  • The driving process of technological innovation in construction: a
           firm-level CDM analysis

    • Free pre-print version: Loading...

      Authors: Zheng Gong, Nannan Wang
      Abstract: Innovation has been acknowledged as the key for modern industries. However, the construction industry is criticised for being poor in innovation performance compared to other industry sectors. Large construction firms are the main contributor to technological innovation in the construction industry, but the driving process of their technological innovation has not yet been fully investigated in previous studies. The purpose of this paper is to provide quantitative analysis of the technological innovation driving process of large construction firms. An extended crépon, duguet and mairesse (CDM) model has been developed to analyse the key influencing factors for technological innovation in construction firms. The sample data are selected from the world’s largest construction market, China, and include 129 listed construction firms. The results show significant positive correlation between R&D investment and innovation output and also between innovation output and performance. The effect of influencing factors on the R&D investment, innovation output and performance are also revealed by the empirical study. The underlying reasons are discussed and suggestions are given for the construction industry to improve the technological innovation capacity of construction firms. This research contributes to the literature of construction innovation and benefits practitioners by providing a quantitative approach to demonstrate the driving process of innovation in construction firms.

  • Productivity and innovation in the Japanese construction industry

    • Free pre-print version: Loading...

      Authors: Koki Arai, Emi Morimoto
      Abstract: The purpose of this study is to identify the essential elements required for innovation in the construction industry. To this end, the authors assessed the innovation at three levels: the firm growth account level, the firm behaviour level and the level of the firm’s experts. The factors influencing innovation at each level were identified and synthesised into guiding strategies for innovation. Three methods were combined to develop a mode of thinking for innovation. First, at the semi-macro level, the authors identified the factors that influence the total factor productivity (TFP) by regressing the TFP across firms of the construction industry on a variety of extrinsic factors. Second, at the firm level, the authors extracted actual innovative firms from a large amount of public procurement individual data. The authors analysed the behaviours of these innovative firms. Third, the authors conducted a survey of expert-level personnel. In addition, a text analysis was performed to determine what was perceived by experts as a factor that leads to innovation. The authors analysed the TFP, the behaviour of innovative firms and the perception issues between industry experts and stakeholders regarding innovation. As a result, two factors were identified. The first factor was the expectation of a positive solution to the problem through monopoly profits, future benefits and increased efficiency. The second factor was peer pressure from other organisations of a similar nature, peer pressure from users and technical information, as well as competitive conditions, e.g. recent environmental growth, including relevant innovations. In the context of innovation, static and dynamic thinking were important requirements. Static concepts were based on the accumulation of knowledge, such as patents and technological progress. Dynamic thinking involved a future outlook, including a competitive environment as a necessary condition. Actual technological innovation was driven by incentives and expectations. According to the results of this study, the authors make the following recommendations for enhancing the construction-industry innovation in Japan: do not rely on a patent policy to drive innovation, create an environment that encourages competition and develop an ongoing initiative that encourages and rewards innovation. This study was novel, in that the nature of innovation was investigated at three levels: the TFP, firm behaviour and expert perceptions. The identification and extraction of the two resulting points – statically necessary and dynamically necessary elements – was a significant contribution of the study.

  • Introducing a fuzzy MCDM model for financial management in multiple
           project environments

    • Free pre-print version: Loading...

      Authors: Mohammad Reza Afshar, Hamed Asadzadeh Zenozi
      Abstract: Statistics in the construction industry show that lack of timely injection of funds to projects by clients is one of the common problems confronted by contractors. This problem is intensified when contractors construct multiple projects simultaneously. In these situations, it is rational that contractors share their financial resources among projects according to project conditions and the firm’s vision. This study aims to propose a fuzzy multi-criteria decision making (MCDM) model for financial management in multiple project environments. First, the project evaluation criteria are defined using exploratory study and interviews with experts. Second, the weights of criteria are determined based on company strategies. Then, each of the projects are evaluated in each criterion. Finally, the fuzzy weighted average approach is used to determine the proportion of each project from the financial resources. The proposed model is prepared as an applicable model for general contractors to assign financial recourses among the multiple projects optimally. As a lack of applicable model assigning the financial resources among the multiple projects, this study is one of the first research studies that proposed a fuzzy MCDM model to assign financial resources to multiple projects optimally.

  • Creating a case for innovation acceleration in the New Zealand building
           industry

    • Free pre-print version: Loading...

      Authors: Johnson Adafin, Suzanne Wilkinson, James O. B. Rotimi, Casimir MacGregor, John Tookey, Regan Potangaroa
      Abstract: This study aims to examine how innovation can be accelerated within the New Zealand (NZ) building industry to improve the productivity and efficiency of the industry. The study adopted a mixed philosophical approach combining interpretivism and post-positivism. Data for the study were obtained through a focus group of 50 practitioners that were selected using a stratified sampling procedure. All focus group data were audio-recorded, notes of the discussions were taken and then transcribed, de-identified and managed using NVivo software. Data analysis was undertaken using thematic analysis and inductive reasoning consistent with interpretative phenomenological analysis. The study findings revealed that the industry could benefit from the adoption of new and emerging technologies to improve its performance, especially its productivity and efficiency. Key drivers for the adoption of innovative practices included the adaptation of “local best practices” from case studies that would consist of stories of successful innovations that could foster confidence in future innovation. It was also identified that Government and industry should nurture innovation through collaborative contracts, policies and regulations. Further, it was highlighted that a culture of innovation needed to be developed to help nurture competencies and capability within the industry workforce. This study provides an in-depth examination of the need for innovation from the point of view of building industry practitioners. This study provides a useful starting-off point for further research and for the creation of policies that could help to support and accelerate innovation within the NZ building industry. NZ’s building industry productivity and efficiency have been sub-optimal relative to other industries. But using evidence from the experiences and knowledge of industry practitioners, strategies can be developed to accelerate innovation within the NZ building industry that could help reverse industry performance. Further, the research findings can help inform government policies to develop support mechanisms that could encourage innovation in the industry in NZ. In addition, it is anticipated that the findings will provide a useful set of guidance for other countries that have similar market and physical constraints as those encountered by NZ. There is a dearth of empirical studies on innovation in the NZ building industry which the current study contributes to. By sharing industry practitioners’ experiences and knowledge of innovation, the paper seeks to counteract more technocratic and technological optimist accounts of innovation within the building industry. Further, the paper provides insights into how the NZ building industry can transform its performance through innovation.

  • Mechanisms for enhancing the use of social media for knowledge sharing by
           the construction professionals

    • Free pre-print version: Loading...

      Authors: Ramtin Etemadi, Carol K.H. Hon, Karen Manley, Glen Murphy
      Abstract: This paper aims to investigate the mechanisms for transforming construction professionals’ intentions into use of social media (SM) for knowledge sharing (KS). The objectives are to: identify the common types of SM platforms used by the construction professionals for KS; identify the key problems influencing transformation of the construction professionals’ intentions into use of SM for KS; identify the factors mitigating the problems; and provide recommendations for enhancing construction professionals’ use of SM for KS. The data was collected through semi-structured interviews with Australian construction professionals and analysed using grounded theory (GT). The outcomes of the analyses formed a framework for the enhancement of SM use for KS. The findings show that private SM followed by enterprise SM are more appealing to the construction professionals for KS compared to public SM; and uncertainties about users’ privacy/confidentiality and the quality of the shared knowledge adversely affect the transformation of the construction professionals’ intentions into use of SM for KS. Three types of trust are identified as the mitigators of the identified problems. A framework is proffered to enhance SM use for KS by construction professionals. This paper contributes to the construction literature by developing a GT to explain the factors which impact the transformation of the construction professionals’ intentions into use of SM for KS. Additionally, the practical contribution of this study is the provision of framework constituting recommendations for the enhancement of SM use for KS.

  • Evaluating distance perception for architecture design alternatives in
           immersive virtual environment: a comparative study

    • Free pre-print version: Loading...

      Authors: Narmin Abouelkhier, Doaa Shawky, Mohamed Marzouk
      Abstract: Immersive virtual environments (IVEs) aid in perceiving spaces by providing a platform for all stakeholders to make better decisions at early design stages. Nevertheless, they are not widely used in architecture, engineering and construction (AEC) industry. This paper aims to illustrate the impact of level of details (LODs) in participants’ perception for architecture design alternatives in IVEs. This paper presents an approach to estimate how distance perception varies between real and virtual environments when different design alternatives are implemented. First, a fully three-dimensional (3D) model for a replica meeting room was created and the level of details (LODs) inside the IVE was gradually modified. Second, a questionnaire was designed to collect responses about how the perceived experience of an IVE is compared to that of the physical environment, where the two environments have the same dimensions. Twenty-six participants were recruited in this study to estimate eight distances in the IVEs while putting on a head-mounted display. Obtained results show that decreasing LOD has negative effect on users’ perception. Thus, when all of the available LODs were added to the IVE, the perceived perception was significantly enhanced. These findings emphasize the relation between the physical details and distance perception in IVEs and shed light on how to design virtual reality architectural models in an efficient manner. Different experiments were conducted to analyze perception differences associated with factors such as LODs, gender and whether participants are wearing glasses.

  • Taxonomic categories for commissioning and startup hot spot strategies

    • Free pre-print version: Loading...

      Authors: Brant Mock, James O’Connor
      Abstract: The purpose of this study is to better understand distinct solution strategy types for common commissioning and startup problems (Hot Spots) in the construction of industrial facilities. The authors also sought to better understand which solution strategy types offer the best value for the effort required. The authors used a method of qualitative coding of text-based data to identify themes, patterns and trends from a collection of 178 commissioning and startup (CSU) solution strategies for the CSU Hot Spots. Coding categories emerged after multiple iterations. The authors also mapped high-value, low-effort solution strategies across the categories. Chi-squared testing and analysis of proportion statistics help quantitatively justify this qualitative research. The authors identified 12 distinct coding categories and showed that they follow a non-uniform distribution via statistical testing. Those strategy types which provide particularly good value for the effort required are identified (such as quality assurance and control strategies), as well as those strategy types that do not. Research is limited to CSU for the construction of industrial facilities. The findings are also limited to a subset of the most commonly problematic CSU activities. Many findings may be beneficial for heavy civil and commercial CSU as well. Coding categories, definitions and descriptions provide a good overview of all 178 solution strategies for CSU project professionals. Implementing certain types of solutions or solution programs may allow CSU managers to prevent multiple Hot Spots from becoming problematic or to keep problems already occurring from becoming worse. Managers will also benefit from knowledge about which strategy types are more likely to give a higher value for lower effort. Qualitative coding and analysis of solution strategies for common CSU problems have never been conducted so rigorously in any other CSU study. This method has yielded results distinct from other CSU studies which have used quantitative methods. Insights from findings have advanced the body of knowledge surrounding problem-solving in the commissioning and startup sub-discipline.

  • IPD-inspired framework for measuring stakeholder integration in
           public-private partnerships

    • Free pre-print version: Loading...

      Authors: Zeina Malaeb, Farook R. Hamzeh
      Abstract: In a public-private partnership (PPP), the private sector is represented by a company termed the special purpose vehicle (SPV), which combines different stakeholders including designers, contractors and service providers under one umbrella. Correct SPV team selection is critical to ensure PPP success as the SPV must act as an integrated entity. In fact, unless the SPV takes an active role in developing trust and promoting integration principles, segmentation of interests, highly adversarial atmospheres, loss of value and economic inefficiency will prevail. Absence of awareness of such principles among stakeholders and the scarcity of literature investigating SPV stakeholder integration create great risks that jeopardize project success. Accordingly, to mitigate the aforementioned risks and provide stakeholders with both the knowledge and the tools to instigate and maintain integration, this paper aims to develop and test a framework to measure SPV stakeholder integration, inspired by the correlation between integrated project delivery (IPD) and SPV operations. Following a design science research approach, a structured review is conducted to develop the SPV integration metrics and framework. The framework is then validated through face validation by a panel of industry and academic experts to assess its applicability in measuring SPV integration. Finally, the framework is tested on a well-recognized international PPP project to measure the SPV integration level, and the outcomes are discussed and analyzed. The framework was able to assess the integration level of the studied SPV highlighting several areas of low-integration settings and providing guidance for achieving better integration. This research is the first that develops a model to investigate the SPV’s integration level, from a holistic IPD perspective, to enable successful relationship management and enhance collaboration success. This study inspires practical recommendations for PPP practitioners to reduce the risks of segregated SPVs and their contribution to PPP failure.

      Abstract: The practice of artificial intelligence (AI) is increasingly being promoted by technology developers. However, its adoption rate is still reported as low in the construction industry due to a lack of expertise and the limited reliable applications for AI technology. Hence, this paper aims to present the detailed outcome of experimentations evaluating the applicability and the performance of AI object detection algorithms for construction modular object detection. This paper provides a thorough evaluation of two deep learning algorithms for object detection, including the faster region-based convolutional neural network (faster RCNN) and single shot multi-box detector (SSD). Two types of metrics are also presented; first, the average recall and mean average precision by image pixels; second, the recall and precision by counting. To conduct the experiments using the selected algorithms, four infrastructure and building construction sites are chosen to collect the required data, including a total of 990 images of three different but common modular objects, including modular panels, safety barricades and site fences. The results of the comprehensive evaluation of the algorithms show that the performance of faster RCNN and SSD depends on the context that detection occurs. Indeed, surrounding objects and the backgrounds of the objects affect the level of accuracy obtained from the AI analysis and may particularly effect precision and recall. The analysis of loss lines shows that the loss lines for selected objects depend on both their geometry and the image background. The results on selected objects show that faster RCNN offers higher accuracy than SSD for detection of selected objects. The results show that modular object detection is crucial in construction for the achievement of the required information for project quality and safety objectives. The detection process can significantly improve monitoring object installation progress in an accurate and machine-based manner avoiding human errors. The results of this paper are limited to three construction sites, but future investigations can cover more tasks or objects from different construction sites in a fully automated manner. This paper’s originality lies in offering new AI applications in modular construction, using a large first-hand data set collected from three construction sites. Furthermore, the paper presents the scientific evaluation results of implementing recent object detection algorithms across a set of extended metrics using the original training and validation data sets to improve the generalisability of the experimentation. This paper also provides the practitioners and scholars with a workflow on AI applications in the modular context and the first-hand referencing data.

  • Role of BIM and energy simulation tools in designing zero-net energy homes

    • Free pre-print version: Loading...

      Authors: Shahryar Habibi
      Abstract: The purpose of this study is to design a zero-energy home, which is known to be capable of balancing its own energy production and consumption close to zero. Development of low-energy homes and zero-net energy houses (ZEHs) is vital to move toward energy efficiency and sustainability in the built environment. To achieve zero or low energy targets in homes, it is essential to use the design process that minimizes the need for active mechanical systems. The methodology discussed in this paper consists of an interfacing building information modeling (BIM) tool and a simulation software to determine the potential influence of phase change materials on designing zero-net energy homes. BIM plays a key role in advancing methods for architects and designers to communicate through a common software platform, analyze energy performance through all stages of the design and construction process and make decisions for improving energy efficiency in the built environment. This paper reviews the literature relevant to the role of BIM in helping energy simulation for the performance of residential homes to more advanced levels and in modeling the integrated design process of ZEHs.

      Authors: Mohamed Kasbar, Sheryl Staub-French, Angelique Pilon, Erik Poirier, Zahra Teshnizi, Thomas Froese
      Abstract: The purpose of this paper is to improve the understanding of the impact of mass timber construction methods on construction performance through the successful delivery of the first-of-a-kind tall wood building, Brock Commons Tallwood House (Tallwood House). This paper is one of a set of papers examining the project; companion papers describe innovations used during the mass timber design and construction processes. A mixed-method, longitudinal case study approach was used in this research project to investigate and document the Tallwood House project. Quantitative data were collected to perform the following analysis: hook time, the variability of productivity and schedule reliability. Members of the research team observed construction progress, meetings and decision-making, conducted periodic interviews and reviewed project artifacts. The research presented in this paper is the culmination of a longitudinal study aimed at studying the innovation process on a project where radical innovations of structural systems were developed. Prefabrication, combined with the use of a virtual design and construction (VDC) model for planning and fabrication and early collaboration with trades, construction managers and consultants, increased the labor productivity of the on-site erection of the mass timber structural components and envelope panels and expedited the construction schedule. This paper details an in-depth investigation into the construction productivity for a unique building project and lessons learned. The case study chosen is the construction of Tallwood House at the University of British Columbia. Tallwood House was the tallest mass-timber hybrid building in the world at the time of its construction.

  • Exploiting digitalization for the coordination of required changes to
           improve engineer-to-order materials flow management

      Authors: Qian Chen, Bryan T. Adey, Carl T. Haas, Daniel M. Hall
      Abstract: The dynamic nature and complexity of construction projects make it challenging to ensure that the engineer-to-order (ETO) materials supplied onsite match changing needs. The quick and efficient communication of required changes in material fabrication, delivery and use, due to changes in the design and construction schedules, is needed to address the challenges. This study aims to provide a novel integrated management framework with its embedded informatics to help major stakeholders efficiently absorb agility during communication to deal with required changes and improve workflows. An integrated management framework is developed that integrates the milestones in look-ahead plans and structured iterative processes for major supply chain stakeholders to quickly disseminate information emanating from changes in design, schedules, production and transportation. A prototype system is devised including the informatics to support the framework, which consists of BIM-RFID functional modules and a central database and uses a client-server architecture. The usefulness of the prototype is illustrated using a construction of part of a fictive but realistic high-rise building. The integrated management framework with the informatics provides major stakeholders with the ability to coordinate their activities efficiently and stimulate their agility (measured by process time) in planning and controlling material information. Although only a fictive example was used, it is shown that the use of the system is likely to result in a substantial reduction in the time required to deal with required changes when delivering ETO materials onsite (by 18% in the example). The functionalities of the prototype system can be easily scaled up to coordinate changes in the design and scheduling of other types of materials. More functional developments are needed to show the extent of the possible improvement for entire construction projects. Future work should focus on investigating the possible improvements for other types and sizes of construction projects, and eventually in real-world construction projects. By fitting the look-ahead plans into structured iterative processes through digital data sharing, stakeholders increased their capability to quickly capture required change information and resolve associated problems. This is particularly useful for the management of ETO supply chain processes, where prefabricated elements such as ductwork, plumbing, and mechanical systems typically have to be modified because of last-minute design and schedule changes. Unlike traditional information technology (IT) based supply chain management practices, this research is characterized by a process-centered management framework that provides explicit decision points over iterative planning processes for major stakeholders to manage material information. The iterations through digital data sharing allow stakeholders to quickly respond to last-minute changes on site, which fundamentally achieves workflow agility in the construction supply chain context.

  • Automatic recognition of labor activity: a machine learning approach to
           capture activity physiological patterns using wearable sensors

      Abstract: The first step toward developing an automated construction workers performance monitoring system is to initially establish a complete and competent activity recognition solution, which is still lacking. This study aims to propose a novel approach of using labor physiological data collected through wearable sensors as means of remote and automatic activity recognition. A pilot study is conducted against three pre-fabrication stone construction workers throughout three full working shifts to test the ability of automatically recognizing the type of activities they perform in-site through their lively measured physiological signals (i.e. blood volume pulse, respiration rate, heart rate, galvanic skin response and skin temperature). The physiological data are broadcasted from wearable sensors to a tablet application developed for this particular purpose, and are therefore used to train and assess the performance of various machine-learning classifiers. A promising result of up to 88% accuracy level for activity recognition was achieved by using an artificial neural network classifier. Nonetheless, special care needs to be taken for some activities that evoke similar physiological patterns. It is expected that blending this method with other currently developed camera-based or kinetic-based methods would yield higher activity recognition accuracy levels. The proposed method complements previously proposed labor tracking methods that focused on monitoring labor trajectories and postures, by using additional rich source of information from labors physiology, for real-time and remote activity recognition. Ultimately, this paves for an automated and comprehensive solution with which construction managers could monitor, control and collect rich real-time data about workers performance remotely.

      Abstract: Systemic innovations emerge and create value in an inter-organisational context. However, innovation studies rarely investigate the role of value creation and value capture among multiple organisations in successful innovation implementation. This paper aims to understand the role of value creation and value capture in the implementation of systemic innovations in construction which is by nature, an inter-organisational context. The empirical research focused on the barriers, enablers and opportunities for value creation and value capture of the Finnish construction project parties when trying to implement mechanical, electrical and plumbing (MEP) prefabrication, which is a systemic innovation. Data were collected through interviews, observations and action workshops. The empirical study identified interaction patterns on how social, political, technical and economic barriers lead to uneven value capturing, lack of value-based procurement and unclear value creation between MEP design and installation. They hinder the implementation of MEP prefabrication. The results point to enablers leading to fairly shared value to all parties, procurement of value and collaborative value creation, thus increasing the usage of MEP prefabrication, a systemic innovation. The study adds new knowledge by demonstrating that the identification of barriers and their interaction with enablers and opportunities for value creation and capture lay a baseline for suggestions on how to implement a systemic innovation. This study stresses the importance of enabling value creation and capture for all construction project parties when implementing a systemic innovation.

      Abstract: While smart building technologies (SBTs) implementation ensures sustainability, their adoption is hampered by latent barriers, especially in project management processes. These latent barriers must be addressed to facilitate the successful and widespread adoption of SBTs. Therefore, this study aims to explore the significant latent barriers inhibiting the project management processes in adopting SBTs in developing countries. A positivist research philosophy couched within a deductive approach was adopted to undertake a quantitative questionnaire survey of 227 project management and design team participants. Descriptive and inferential analytical tools (including a one sample T-test and exploratory factor analysis) were then adopted to interpret data collected. The results reveal that the “high cost of smart sustainable materials and equipment” is the major significant barrier hindering the adoption of SBTs in developing countries. Latent barriers were: “structure and time-related barriers,” “construction-related barriers” and “human, policy and cost-related barriers”. The study contributes novel insights into the prevailing nascent discourse on SBTs from the perspectives of construction project managers and design teams in developing countries, particularly. Furthermore, to the best of the authors’ knowledge, this is the first study that ascertains the significant barriers inhibiting project management processes in adopting SBTs in developing countries.

      Authors: Natalya Sergeeva, Meri Duryan
      Abstract: This paper aims to explore the ways innovation becomes enabled through knowledge management and sharing which has important implications for establishing and sustaining the culture of innovative thinking in project-based construction firms. This study adopts a reflective practitioner perspective to explore this relationship. In total, 30 semi-structured interviews were conducted with the construction sector professionals whose roles are most relevant in the connection between innovation and knowledge management. Thematic analysis and cognitive mapping techniques were used to analyse the interview data. The research findings indicate that due to the complexity of project-based construction firms, a more holistic approach to knowledge management and organisational learning at the firm level is required. This would enable a culture of continuous and coordinated knowledge flow that facilitates innovation and continuous improvement in project-based firms. This paper has important implications for practising managers in project-based construction firms. By better understanding the ways organisational knowledge can be managed to become an enabler of innovation would allow to build and enhance firms’ innovative capabilities, individual and team competencies. There is a real need for innovation knowledge managers as formal job positions in the construction sector. This study contributes to construction innovation and project management research and practice by providing insights into establishing and sustaining the culture of learning and innovative thinking.

      Authors: Kobra Gharouni Jafari, Esmatullah Noorzai, M. Reza Hosseini
      Abstract: This paper aims to explore the potential capabilities of the application of computing features (CFs) in resolving the most common issues that adversely affect performance in architecture, engineering and construction (AEC) projects. Through a comprehensive review of the literature, 10 most significant CFs were identified. Also, the 15 most prevalent issues in AEC projects (AECIs), for which computers can provide remedial solutions, were determined and categorized into three phases of design, construction and operation. Potential impacts of each CF on handling AECIs in each of the three stages were assessed based on experts’ perceptions. CFs are ranked based on their potential on solving the identified AECIs. So too, the order of the most common AECIs is provided in terms of their disposition for being solved by CFs. In this regard, findings reveal that the most effective CF in addressing AECIs is “artificial intelligence” and the most solvable AECI by using CFs is “increased costs and poor budgeting.” Furthermore, the most appropriate CF to handle each AECI is specified, as a result of which, it is inferred CFs are more effective in handling operation-related issues, compared to design, construction phases. The results can provide a profound insight into software/tool selection based on features that enable technological tools and programs to handle AECIs in the three major phases of projects. Moreover, technology providers and vendors are provided with a benchmark to supply products according to the demands of the AEC industry. The study provides a readily available point of reference for practitioners in selecting various CFs for handling common AECIs that affect their projects. A large body of research is available on the evaluation of various computer-based technologies and tools. Nevertheless, little, if any, study exists that explores the potential of underlying CFs of these technologies in addressing endemic problems across various stages of AEC projects. This study is one of the first in its kind that shifts to exploring various CFs, as the main enablers of computer technologies, establish links between these CFs and common issues of projects and assesses the potential of various CFs in addressing common problems of construction projects.

      Authors: Ifeanyi Okpala, Chukwuma Nnaji, Ibukun Awolusi
      Abstract: This study aims to examine relationships between several key technology acceptance variables that predict workers’ wearable sensing devices (WSDs) acceptance in the construction industry by using technology acceptance model, theory of planned behavior and unified theory of acceptance and use of technology (UTAUT) model. The study proposes a hybrid conceptual model to measure construction field workers’ intentions to use WSDs and their usage behaviors. The study introduces variables that are instrumental in understanding and improving WSD acceptance in construction. The study was carried out using a structured literature review, online survey and structural equation modeling. A total of 195 field workers across the USA, with experience in using WSDs, participated in the study. Results indicate that all three theories predict WSD acceptance with variables explaining at least 89% of the variance in actual use, with the UTAUT outperforming other models (91%). However, the differences between the predictive power of these models were not statistically significant. A hybrid conceptual model is proposed using findings from the present study. The study contributes to knowledge and practice by highlighting key variables that influence WSD acceptance. Findings from this study should provide stakeholders with critical insights needed to successfully drive WSD acceptance in the construction industry. To the best of the authors’ knowledge, this is the first study that evaluates the predictive strength of multiple technology acceptance theories and models within the construction worker safety technology domain. Additionally, the study proposes a hybrid conceptual model which could provide practitioners and researchers with information pertinent to enhancing WSD acceptance.

      Authors: Mohamed Fathy Abd Elsalam
      Abstract: This paper could be considered as the first step of grounding the ambitions and speculations about hyper urban planning. In other words, it is just a brief approach for the critical discussion of hyper urban planning field, without too many details or long explanations, so further studying, arguing and additional future research should be done. The scientific methodology is based on descriptive and analytical methods, in addition to case study method of data collection. Therefore, the paper has reviewed 16 case studies, which could arguably be lumped under the title of “hyper urban planning.” The study focuses on proposing a new way to view urban planning, that is the hyper urban planning, which could be considered as a sort of specialized urban branch of advanced level, characterized by special criteria, which stimulates innovative and creative proposals for the future smart cities. Hyper urban planning field generally aims to contribute to liberating and releasing the full creative imagination of the urban planners’ minds, outside the box and away from the exaggerated strict constraints. The study has been based on theoretical aspects in addition to empirical experiments. The practical aspects reflect the potential and promising features of hyper urban planning, especially with regard to using creativity, sustainability and innovative technology solutions. The paper’s analyses show that many hyper urban proposals have a high potential sustainability, environmentally, socially and economically. As urban problems and built environment challenges have become more complex, the proposed vertical eco-cities under the umbrella of hyper urban planning field may arguably be promising and more sustainable urban solutions for the previously mentioned challenges.

      Authors: Buddhini Ginigaddara, Srinath Perera, Yingbin Feng, Payam Rahnamayiezekavat
      Abstract: The construction industry is currently responding to pressures of industrialisation happening across all sectors. Consequently, offsite construction (OSC) has become a vehicle to achieve industrialisation. This requires changes in traditional construction processes resulting in possible changes in construction skill requirements. Accordingly, the purpose of this study is to identify and review prevailing OSC practices and skills in the Australian construction industry. This study aims to critically analyse the existing skill profile classifications through a single case study and identify the need for an OSC specific skill classification. This study follows a case study design, with an in-depth analysis of a single construction project. Only one case study was studied because scientifically, one example was enough to prove that the prevailing skill classifications do not represent OSC skills in a modern context. Data was retrospectively collected through semi-structured interviews of project stakeholders representing design, manufacture and assembly. Content analysis was conducted to analyse the collected data and produce findings. This study identifies the inadequacy of the existing classification system, unavailability and the need of OSC specific skill categorisation. It highlights new skills that enter OSC; building information modelling engineer, three-dimensional draftsperson, OSC project manager and project coordinator, which are not identified in the available Australian skill classifications. These, together with existing skills need to be carved in to create a new skill classification. This study is the first of its kind where a comprehensive OSC project is evaluated as a case study to determine OSC skill classification requirements in Australia.

           from supply chain stakeholders

    • Free pre-print version: Loading...

      Authors: Vineeth Dharmapalan, William J. O’Brien, Douglas Morrice, Minhyuk Jung
      Abstract: Stakeholders of construction projects exhibit different perceptions regarding the visibility of materials in the supply chain, which affects the timely delivery and installation of materials. This study aims to quantitatively investigate the differences in viewpoints of owners, contractors, designers and suppliers about the visibility of materials at supply chain locations and different material types during the construction of industrial projects. Survey data about visibility at nine typical supply chain locations and three common material types were collected from owner, contractor, designer and supplier groups and analyzed using frequency statistics, relative importance index and tests for equality of odds. Offsite Tier-2 supplier, ports and kitting site shows the lowest visibility level for the owner, contractor, supplier and designer groups. Also, the supplier group tends to have adequate to extreme visibility at the Tier-2 supplier, kitting site and during transportation compared to owner, contractor and designer groups. An example finding concerning the visibility of material types is that owners and contractors perceive prefabricated material requires higher visibility than all other material types. The findings are limited to construction projects in the industrial sector. Further, the survey participants were based in North America at the time of participation. The study’s findings indicate how visibility is spread across supply chain locations and for material types for the owners, contractors, suppliers and designers of industrial projects. As such, academia and industry’s research and investment efforts can be more focused on locations and material types that need improvement. Industrial projects play an essential part in improving society’s daily lives, and this study’s findings contribute to improving the efficiency of the supply chain during construction of industrial projects. Although previous studies mentioned the need and importance of visibility improvement, none have sought to understand the perception of leading supply chain stakeholders about visibility at supply chain locations and of material types. This study’s findings provide specific insights and directions for advancing in these areas with regard to supply chain visibility.

      Abstract: This paper aims to focus on 11 digital technologies (i.e. building information modeling, artificial intelligence and machine learning, 3D scanning, sensors, robots/automation, digital twin, virtual reality, 3D printing, drones, cloud computing and self-driving vehicles) that are portrayed in future trend reports and hype curves. The study concentrates on the current usage and knowledge of digital technologies in the Swedish architecture, engineering and construction (AEC) industry to gain an insight in the possible expectations and future trajectory of these digital technologies. The study applies an abductive approach which is based on three different types of methods. These methods are a literature and document study which focused on 11 digital technologies, two workshops with industry (13 participants) and an online survey (N = 84). The paper contributes to a current state analysis of the Swedish AEC industry concerning digital technologies and discusses the trajectory of these technologies for the AEC industry. The paper identifies hype factors, in which the knowledge of a digital technology is related to its usage. From the hype factors, four zones that show different stages of digital technology usage and maturity in the industry are induced. The contribution of the paper is twofold. The paper shows insight into opportunities, the current barriers, use and knowledge of digital technologies for the different actors in the AEC industry. Furthermore, the study shows that the AEC industry is behind the traditional Gartner hype curves and contributes with defining four zones for digital technologies for the Swedish AEC industry: confusion, excitement, experimentation and integration.

           manufacturing in the UK housing sector

      Authors: Jennifer Charlson, Nenpin Dimka
      Abstract: The purpose of this study is to gain insight into procurement routes and forms of contract used for volumetric offsite manufacturing (VOSM) in the housing sector of the UK West Midlands. Seminal literature and government reports have established the potential of offsite technologies to improve the supply of quality housing in the UK. However, the lack of a structured procurement route, common to manufacturing approaches in construction, has significantly contributed to delays in large scale adoption. To achieve the research intention, an exploratory study was undertaken. A literature review of seminal literature and government papers was conducted to establish and benchmark current trends in context. Data was collected using focus groups and interviews with a housing association and housing VOSMs. Grounded theory was used to analyse data and inductively generate themes leading to an original procurement model. The issues identified in the delivery of volumetric housing were categorised into three themes. The findings suggest a limited familiarity with offsite manufacturing (OSM) by housing providers. Albeit, a willingness to adopt these technologies to deliver housing were demonstrated by trial attempts. However, due to limited knowledge, the approach to procurement is by adapting existing procurement models, which are not ideal and obstruct the potential benefits of using offsite technologies primarily because of the significant difference in processes. Also, geographical location influenced procurement decisions when comparing cost with conventional procurement and the dearth of specific government incentives to deliver housing using offsite technologies. This study proposes a procurement model for VOSM. The results have implications for decisions about procurement routes and contractual terms used by housing providers delivering volumetric offsite manufactured housing at scale. Although this study focussed on the West Midlands region, most of the issues identified were not geographically unique. This study contributes to the existing body of knowledge on potential barriers to the adoption of OSM in the housing sector of the UK. The findings will be of value to stakeholders involved in delivering housing and offers a useful contextual basis for future research.

  • Impact of proactive behaviour antecedents on construction project
           managers’ performance

      Authors: Georgios Kapogiannis, Terence Fernando, Ahmed Mohammed Alkhard
      Abstract: Many aspects of social behaviour are manifested in project managers in interaction with team members in the construction sector. Proactive behaviour as a social behaviour impacts on project and organizational effectiveness. This paper aims to explore and explain how project managers’ proactive behaviour could be enhanced in a project by the use of integrated collaborative environments. The paper aims to discuss these issues. To investigate this interrelationship, researchers used a survey methodology involving gathering both quantitative and qualitative data, and used regression analysis to assess the strength of impact of proactive behaviour antecedents on project manages’ performance on a construction project when using integrated collaborative technologies. For the qualitative data, researchers used content analysis. The research showed that by developing a proactive personality, the construction project manager is more likely to pre-identify “accurately” project time and costs, and to identify project culture, collaboration strategy and project risks. Moreover, co-worker trust as a proactive behaviour antecedent has been shown to impact on raising quality issues in a project. Furthermore, project managers’ flexibility could assist them in designing procurement strategies as well as designing a project business plan and avoiding conflict. Nevertheless, flexibility, including self-efficacy, control appraisal, change orientation, job autonomy and supportive supervision, plays a significant role in the development of proactive behaviour in construction project managers and enhances project performance. The sample is limited, but the research methodology is acceptable because the authors use mixed approach to check the correlation. How project managers can use integrated collaborative technologies on developing their proactive behaviour and thus impacting project performance is observed. The value of this paper is to contribute understanding of the impact of the use of integrated collaborative technologies on developing project managers’ proactive behaviour and thus impacting project performance.

      Authors: Joseph Kwame Ofori-Kuragu, Robert Osei-Kyei
      Abstract: The purpose of this paper is to explore the current state of popular modern methods of construction (MMC) and pre-manufactured construction in the construction industry and propose a framework for future implications for practice and future research. This technical paper is based on a narrative review of the extant literature on the subject. First, the Scopus search engine was used to retrieve relevant papers on MMC, offsite and pre-manufactured construction. Second, institutional literature such as reports by industry professional and trade bodies, literature from leading technology firms and contractors with experience of MMC were extracted. These two strands of literature were synthesised and a comprehensive discussion on the topic was provided. Results show that journal publications on MMC and pre-manufactured construction have increased in the past decade. The paper found significant advances in the development of premanufactured and offsite construction approaches with many benefits. Offsite and pre-manufactured construction are viable and sustainable systems currently suitable for wider adoption as the mainstream construction method. This technical paper based on an integrative review of relevant literature could have benefitted from interviews of professionals with experience of offsite and pre-manufacture techniques and from wider availability of current academic publications on the subject. Validation of the framework has not been undertaken. Not much-published work has been undertaken on the current state of development globally and the viability of these construction approaches. This paper evaluates evidence from academic and industry sources to address this gap. A framework has been developed which can help the industry’s industrialisation drive.

      Abstract: Advanced construction technologies (ACTs) are transforming infrastructure projects, yet there has been little research into and theorization of the process by which these innovations are diffused. The purpose of this paper is to address this paucity of research by exploring the problems of information asymmetries between vendors and customers in the ACT diffusion process. Specifically, the paper explores whether information asymmetries exist between vendors and customers in the ACT diffusion process and what forms they take. A structured survey of 153 vendors and customers of advanced construction technologies was undertaken across three international ACT exhibitions in Australia. By comparing the perspectives of both customers and vendors across 15 technology diffusion process variables using importance-performance analysis and principal component analysis, significant differences are found between vendors’ and customers’ perceptions of how effectively information flows in the ACT diffusion process. The results show that vendors are significantly more optimistic than customers about information asymmetries on a wide range of diffusion variables. They also highlight significant potential for information asymmetries to occur which can undermine the advanced technology diffusion process. The results provide important new conceptual and practical insights into an under-researched area, which is of increasing importance to a major industry, which is being transformed by advanced technological developments.

  • Simulation of vehicle movements for planning construction logistics
           centres

      Authors: Fei Jin Ying, Michael O’Sullivan, Ivo Adan
      Abstract: Materials supply is one of the important elements in construction operation and a major factor affecting the quality of construction projects. Many industries look to manage materials effectively by attempting to integrate logistics processes into logistics chains of suppliers and customers. Logistics processes, being crucial for successful completion of construction projects, but in fact, auxiliary, are often entrusted to external professionals specialised in logistic services, such as logistics centres. However, this tendency is yet to be developed in construction. The purpose of this paper is to develop a simulation framework for the examination of potential improvements of logistics performance using logistics centres. A case study approach was adopted with computer simulation using Flexsim. Data of vehicle movements were collected during construction on-site from the start of construction to “hand-over” to the building owner. The ideal location of a logistics centre is identified using vehicle movements data collected on the site. The potential improvements of the planned centre are then evaluated by simulating various scenarios of vehicle movements. The enclosed results from the simulations indicate that using a logistics centre will reduce waste for the construction project considered. The paper emphasises that creating a logistics centre for a project can improve construction logistics performance, by consolidating and optimizing both off-site and on-site logistics, especially when the site condition is prohibitive (small footprint with limited loading bay area). Establishing logistics centres may help find ways of making the overall construction project more effective by improving the management of materials.

      Abstract: This paper aims to identify and examine the factors that influence construction industry-university (IU) collaboration and develop the likelihood model of a potential industry partner within the construction industry to collaborate with universities. Mix method data collection including questionnaire survey and focus groups were used for data collection. The collected data were analysed using descriptive and inferential statistical methods to identify and examine factors. These findings were then used to develop the likelihood predictive model of IU collaboration. A well-known artificial neural network (ANN) model, was trained and cross-validated to develop the predictive model. The study identified company size (number of employees and approximate annual turnover), the length of experience in the construction industry, previous IU collaboration, the importance of innovation and motivation of innovation for short term showed statistically significant influence on the likelihood of collaboration. The study also revealed there was an increase in interest amongst companies to engage the university in collaborative research. The ANN model successfully predicted the likelihood of a potential construction partner to collaborate with universities at the accuracy of 85.5%, which was considered as a reasonably good model. The study investigated the nature of collaboration and the factors that can have an impact on the potential IU collaborations and based on that, introduced the implementation of machine learning approach to examine the likelihood of IU collaboration. While the developed model was derived from analysing data set from Western Australian construction industry, the methodology proposed here can be used as the basis of predictive developing models for construction industry elsewhere to help universities in assessing the likelihood for collaborating and partnering with the targeted construction companies.

      Authors: Eymen Cagatay Bilge, Hakan Yaman
      Abstract: Integrated project delivery (IPD) and building information modeling (BIM) has begun to be used in real estate development projects over the past decade to improve collaboration, communication and efficiency. However, the use of BIM and IPD in projects does not always imply that the information is well used and managed. This study aims to explain how information management should be carried out in BIM and IPD projects, what activities should be managed by the information manager and which stakeholder should play this role and why' This study provides a framework on the subject by conducting a comprehensive systematic review in the field of real estate development, BIM, IPD and information management. In this context, the Web of Science and Scopus databases have been systematically reviewed, n = 45 out of a total of n = 1,356 articles and additionally, the BIM documents and standards prepared by public institutions and organizations and industry reports have been examined in detail. The framework for information management roles was established by reviewing the literature. According to this framework, information management activities of information managers are listed in the table that covers all phases of real estate development. The owner should undertake this role as it is the entity that oversees the built asset from planning to the management of that facility. In terms of acquiring information management roles, there is no research on BIM and IPD projects and who will take over this role. This study desired to close this gap in the literature.

  • Actor-network theory and the evolution of complex adaptive supply networks

      Authors: Zelinna Pablo, Kerry London, Peter S.P. Wong, Malik Khalfan
      Abstract: Current understandings of innovation in construction portray it as linear, deterministic phenomena centered around novel objects and technologies deployed in sequentially-organized supply chains. This study aims to develop an enriched understanding of construction innovation as non-linear, socio-material and dynamic phenomena in complex networks by formulating a novel conceptual apparatus of complex adaptive supply networks (CASNs) expanded through actor-network theory (ANT) concepts. This combined CASN/ANT apparatus is mobilized in the context of a qualitative case study involving a housing construction supply network in Australia making use of offsite manufacturing (OSM) techniques. The study shows that innovative technologies such as novel OSM products can play an important though not necessarily deterministic role in the evolution of CASNs. The study also explicates the process by which the enrollment of non-human agents and the resulting CASN evolution are linked: innovative technologies shape human and non-human interactions in ways that redefine task delegation, role definition and schemas that are fundamental to the shape of CASNs. Findings provide a compelling empirical basis for arguing that CASNs must be conceptualized as heterogeneous systems and that innovation in construction must be understood as non-linear, socio-material and dynamic, rather than linear and driven by technological determinism. The study also interrogates limiting notions of supply chains and supports the notion of alternative inter-organizational forms to understand construction project work.

      Authors: Lovelin Ifeoma Obi, Mohammed Arif, Bankole Awuzie, Rubina Islam, Aman Deep Gupta, Robert Walton
      Abstract: Effective cost performance is a crucial criterion measuring successful project management in public-housing projects. This paper aims to analyse the vital underlying factors surrounding the successful cost management process (CMP) outcomes in public housing projects (PHPs). The research was conducted in three stages. The first stage consisted of a detailed literature review to document success factors affecting cost performances and management. In stage two, brainstorming sessions were undertaken with construction experts knowledgeable in cost management practices and have been involved in PHPs. These sessions were used to refine those success factors for the PHPs settings and define their criticality with respect to the CMP stages using interpretive ranking process. In stage three, focus group sessions were performed to validate the interrelationships of the contextualised critical success factors. The top three most critical factors for successful implementation and outcomes at all CMP stages in PHPs settings were found to relate to competencies, team qualities and collaborative practices of the project team. Early contractor involvement and effective construction planning and management also emerged relevant to the process. Government project departments, project managers and construction organisations (consultants and contractors) need to commit and mandate continuous development of cost management competencies for all professionals engaged in PHPs. Channels supporting team integration and collaborative practices between design and construction teams are required to increase the likelihood of successful project cost management practice and outcomes in PHPs. The research has developed a factor-process relationship model that can be used to improve and evaluate the efficacy of CMP implementation in PHP settings.

      Abstract: The purpose of this paper is to present the construction process innovations that enabled the successful delivery of the hybrid mass timber high-rise building in Canada, the Brock Commons Tallwood House at the University of British Columbia. It is one of a set of papers examining the project, including companion papers that describe innovations in the mass timber design process and the impact of these innovations on construction performance. The focus of this paper is on innovation in the construction phase and its relationship to innovations implemented in previous project phases. A mixed-method, longitudinal case study approach was used in this research project to investigate and document the Tallwood House project over a three-year period. Both quantitative and qualitative data collection and analysis techniques were used. Members of the research team observed prefabrication and construction, conducted periodic interviews and reviewed project artefacts. The research identified three innovation “clusters,” including the use of innovative tools, techniques and strategies in the design and construction processes and the role they played in delivering the project. The “clusters” were further characterized according to the type of “connectivity” they afforded, either facilitation, operationalization or materialization. These two perspectives support a compounding view on innovation and help to understand how it can flow throughout a project’s life cycle and across its supply chain. Three process-based innovations were initiated during the design phase, integrated design process, building information modeling and virtual design and construction and flowed through to the construction phase. These were seen to enable the creation of connections that were crucial to the overall success of the project. These innovations were operationalized and enacted through the construction phase as design for manufacturing and assembly and prefabrication, staged construction and just-in-time delivery, integration of safety and risk management and a rigorous quality control and quality assurance process. Finally, a full-scale mock-up was produced for practice and constructability assessment, materializing the radical product innovation that was the mass timber structure. These strategies are used together for a synergistic and integrated approach to increase productivity, expedite the construction schedule and develop an innovative building product. This paper details an in-depth investigation into the diffusion dynamics of multiple systemic innovations for the construction process of a unique building project, the tools and techniques used by the construction manager and team, and the challenges, solutions and lessons learned.

      Authors: Gursans Guven, Esin Ergen
      Abstract: The purpose of this study is to monitor the progress of construction activities in an automated way by using sensor-based technologies for tracking multiple resources that are used in building construction. An automated on-site progress monitoring approach was proposed and a proof-of-concept prototype was developed, followed by a field experimentation study at a high-rise building construction site. The developed approach was used to integrate sensor data collected from multiple resources used in different steps of an activity. It incorporated the domain-specific heuristics that were related to the site layout conditions and method of activity. The prototype estimated the overall progress with 95% accuracy. More accurate and up-to-date progress measurement was achieved compared to the manual approach, and the need for visual inspections and manual data collection from the field was eliminated. Overall, the field experiments demonstrated that low-cost implementation is possible, if readily available or embedded sensors on equipment are used. Previous studies either monitored one particular piece of equipment or the developed approaches were only applicable to limited activity types. This study demonstrated that it is technically feasible to determine progress at the site by fusing sensor data that are collected from multiple resources during the construction of building superstructure. The rule-based reasoning algorithms, which were developed based on a typical work practice of cranes and hoists, can be adapted to other activities that involve transferring bulk materials and use cranes and/or hoists for material handling.

      Abstract: Accidents resulting from poorly planned or setup work environments are a major concern within the construction industry. While traditional education and training of personnel offer well-known approaches for establishing safe work practices, serious games in virtual reality (VR) are increasingly being used as a complementary approach for active learning experiences. By taking full advantage of data collection and the interactions possible in the virtual environment, the education and training of construction personnel improves by using non-biased feedback and immersion. This research presents a framework for the generation and automated assessment of VR data. The proposed approach is tested and evaluated in a virtual work environment consisting of multiple hazards. VR requires expensive hardware, technical knowledge and user acceptance to run the games effectively. An effort has been made to transfer the advantages VR gives to a physical setup. This is done using a light detection and ranging sensing system, which collects similar data and enables the same learning experiences. Encouraging results on the participants’ experiences are presented and discussed based on actual needs in the Danish construction industry. An outlook presents future avenues towards enhancing existing learning methods. The proposed method will help develop active learning environments, which could lead to safer construction work stations in the future, either through VR or physical simulations. The utilization of run-time data collection and automatic analysis allows for better personalized feedback in the construction safety training. Furthermore, this study investigates the possibility of transferring the benefits of this system to a physical setup that is easier to use on construction sites without investing in a full VR setup.

      Authors: Cheng Gong , Hongyu Xu , Feng Xiong , Jian Zuo , Na Dong
      Abstract: Some papers have investigated the complex factors impacting building information modeling (BIM) application in prefabricated buildings (PBs), but few paid attention to their interaction relationships. Ignoring the fact that different factors are not isolated may lead to some key factors being overlooked without appropriate improvement strategies being proposed. This paper aims to analyze those factors and their inter-relationships, with the view to identify the critical factors and their interaction relationships so as to derive constructive strategies that would effectively facilitate BIM adoption in Chinese prefabrication. First, factors influencing BIM application in prefabrication are extracted and collated by literature review, expert interview and analysis of PBs characteristics. Thereafter, an evaluation laboratory (decision-making trial and evaluation laboratory) and interpretive structural modeling are used to explore the relationships and hierarchy among the factors. Based on the degree of cause and centrality, critical factors are extracted and the interaction relationship are investigated. The results show that BIM policies and standards for PBs are the main causal factors. The maturity of BIM software and BIM data interface for PBs, willingness to share data, the strategic goals of the enterprise, BIM law and BIM input and benefit are the main transitional factors while BIM staff and workflow, enterprise attitude, distribution of BIM liability and cooperation of participants are the main direct factors. Based on the above findings, corresponding improvement strategies are proposed so as to promote BIM application in prefabrication and the rapid development of China’s PBs efficiently.

      Abstract: Industrialized construction (IC) is promoted to address some of the ills associated with the processes and products of the traditional construction approach. With several successful projects, IC is progressively becoming a preferred alternative construction approach and spurred the interest of contractors, developers and housing authorities in the technology. Increasingly, these stakeholders are keen to ascertain the compatibility and feasibility of using IC in their projects. This paper aims to develop a knowledge-based decision support framework for implementing industrialized construction projects (ICPs) that can facilitate better and informed decision-making when deciding to implement ICPs. A comprehensive literature review was implemented to recruit 40 decision support factors (DSFs) and grouped into project requirements, location and site attribute, labour considerations and organizational factors. A 3-member expert panel validated the relevance of 35 DSFs, which became candidates for a structured questionnaire survey of experts in 18 countries. Statistical techniques are used to evaluate and prioritize the DSFs, leading to the development of a conceptual framework. Statistical analysis revealed 33 significant DSFs. The top five most significant factors that could influence the decision to implement IC in a project include a stringent requirement for project quality control, suitability of the design for IC, organizational readiness and competencies in ICPs, client receptivity to IC and the need to minimize field construction time. A framework of project requirements, location and site attributes, labour considerations and organizational factors was proposed as decision support. The proposed framework may help to inform decision-making regarding the implementation of IC in a project. It has wider applicability because it includes technical, managerial and operational aspects of and the required competencies for IC, which are shared between project types and territories. The prioritized DSFs could be used as a guide when implementing IC, especially in countries where bespoke decision support systems cannot be developed. The paper delineated the most important DSFs that are shared between IC project types and territories and can be used to investigate the compatibility of using IC in a proposed project. This research constitutes the first exclusive attempt at delineating, quantifying and ranking the sets of decision-making factors, drawing on international data set and contributes to the empirical checklist of DSFs for ICPs.

      Authors: Shawn H. Charles , Alice Chang-Richards , (Kenneth) Tak Wing Yiu
      Abstract: The purpose of this study is to elicit the success factors from empirical evidence, as construction industry requires an improved understanding of factors for managing projects to positive outcomes. Increased stakeholder involvement, including the new technologies, achieving sustainability and safeguarding health and safety, whilst at the same time facing uncertainties, it is crucial to examine whether there are new factors that drive construction projects to succeed, especially from a value-driven perspective. Using a systematic review approach, this research reviewed 172 studies published after 2004. When compared to a comprehensive project success factor framework presented by Chan et al. in 2004, 19 factors are considered new since 2004. Though several scholarly outputs highlighted significant improvements to project operations and innovations in equipment and techniques, there has not been a comprehensive oversight since Chan’s et al. (2004) conceptual framework. This paper investigates 16 years of industry changes and identified two new success factors categories (innovation and sustainability) and 19 new factors that add to Chan’s et al. (2004) study. Consequently, a new framework of factors affecting project success was developed. This paper was very specific in its attempt to find the new and additional success factors for managing construction projects. A new conceptual framework, which includes the newly identified factors, was then developed that will create a greater awareness of stakeholders’ concerns and ultimately contribute to significant improvement in developing project objectives and defining success measures.

      Abstract: Defining building information modelling (BIM) standards for the infrastructure domain is a central issue to the successful implementation of BIM in civil engineering domains. To this end, this paper aims to present a requirements and process analysis for the ports and waterways domain to address the lack of BIM standards development, using the information delivery manual (IDM) approach and the ethos of openBIM standards. This research uses the IDM approach. This involves the definition of use cases, process maps, exchange scenarios and subsequent exchange requirements. All these developments were sourced and validated by a series of international industry consultations. The paper identifies 30 domain relevant use cases collated from existing sources and new cases. An overview and detailed ports and waterways process map (defining actors, activities and data exchanges). The process maps highlighted 38 exchange scenarios between various activities. Various exchange requirements were defined and are discussed in the context of the required information exchange model and the extensions required to fulfil the needs of the domain. The analysis provides the core information for the next steps of development for a substantial extension to the Industry Foundation Classes and the supporting data dictionary standards. Because of the international scope of the research, the outcomes can be applied by any stakeholders in the domain of ports and waterways. Therefore, some variation is expected at a national and organizational level. This research has the potential to accelerate the adoption of openBIM standards within the ports and waterways domain leading to increases in efficiency, collaborative working. This paper reviews the requirements of an identified gap in the provision of openBIM standards relevant and applicable to the domain of ports and waterways.

      Abstract: The traditional construction delivery method is challenged by low trust and collaboration issues, resulting in increased project costs. The integrated project delivery (IPD) method is developed, through a contractual agreement, to overcome these challenges by creating a common set of terms, expectations and project goals. A singular construction case was followed during a four-month period. Data collection consisted of contract documents and a series of semi-structured interviews with representatives from the owner, design-group and contractors. The IPD contract was found to have a number of positive effects; it improved project behavior (e.g. trust, collaboration and communication), increased ownership among project participants and improved buildability of the design, leading to fewer surprises and interruptions in the construction phase. The study also revealed a number of challenges including contractual and legal challenges and involving too many participants in the early phases. Moreover, co-location was identified as a particular important supporting element, to build relations and improve collaboration. This research identified lessons learned from the application, as well as initial barriers and persistent barriers for implementing IPD. To improve IPD application the top three lessons were as follows: 1) the contractual documents should be adapted and signed at an early stage as this increases financial transparency, 2) cost estimates should be carried as an iterative process and project main concept be freezed at an early stage to increase understanding and minimize risks, 3) only the most important project developers should be involved in the early phases, to avoid going into detailed design issues before the main concept is completed.

      Abstract: Water and wastewater (WW) projects are gaining attention in Iran because of shortages of water resources. However, these projects are lengthy and they are accompanied by numerous risks, such as lack of sufficient financial resources. Public–private partnerships (PPPs) are taken into account as a constructive approach to deal with the problem of insufficient government funds and they are increasingly being implemented to construct the required infrastructures in different countries. Although WW projects in PPPs can reduce the government’s debt, investors are still uncertain about this approach. Hence, this study aims to identify and evaluate the risk of all parties involved in WW-PPP projects, from the viewpoint of investor. First, the risk factors which are involved in WW projects are identified by interviewing experts and reviewing the literature by means of fault tree analysis (FTA) tool. Second, the probability and effects of the risky factors which are related to specific event are evaluated and analyzed by hybridization of interval fuzzy Type-2 sets (IT2FS) and risk score formulation. Finally, some solutions are proposed to deal with the most challenging risks. Six gate events, namely, risks which are related to investors such as investor’s consultant-related risks, risky conditions from engineering, procurement, and construction (EPC) contractors’ point of view, risk factors which public sector takes into account, public sector’s consultant-related risks which public sector’s consultant consider challenging and external factors were defined according to the literature. From FTA tool and by interviewing the experts, 94 basic events were identified. Finally, from hybridization of IT2FSs and risk score formulation, top five risks are determined as “Difficulty of injecting financial resources into the project,” “Fluctuation in inflation rate,” “Poor decision-making process” in public sector, “Difficulty of importing the equipment which are required for the project (such as pumps, grain catchers, garbage collectors, etc.) from other countries” and “Impact of risky conditions in other projects on operation of PPP project.” In the absence of a constructive approach for risk identification and a reliable model for evaluating the identified risks in PPP projects, this research project is one of the first research studies which used FTA for identifying risks and hybridization of IT2FSs and risk score formulation for evaluating the risks.

  • Machine learning for the identification of competent project managers for
           construction projects in Nepal

      Abstract: Project manager’s competency is crucial in the construction sector for the successful completion of projects, particularly in the case of developing countries like Nepal. Therefore, it is very essential to select competent project managers by finding the competency factors required by them. Hence, this study aims to identify the characteristics of competent project managers by expert opinion method and to evaluate their competency level by a questionnaire survey to develop a prediction model using a supervised machine learning approach via Waikato Environment for Knowledge Analysis (WEKA), a machine learning tool which predicts Project manager’s performance as “Higher than expected,” “Expected” or “Lower than expected” for the medium complexity construction projects of Nepal (from US$200,000 up to US$10M). The data collection procedure for this research is based on an expert opinion method and survey. Expert opinion method is conducted to find the characteristics of a competent project manager by validating the top 15 competency factors based on literature review. The survey is conducted with the top management to assess their project manager’s competency level. Both qualitative and quantitative approaches are used to collect data for classification and prediction in WEKA, a machine learning tool. The results illustrate that the project managers in Nepal have a high score in leadership skills, personal characteristics, team development and delegation, communication skills, technical skills, problem-solving/coping with situation skills and stakeholder/relationship management skills. Furthermore, among the seven classifiers (naïve Bayes, sequential minimal optimization [SMO], multilayer perceptron, logistic, KStar, J48 and random forest), the accuracy given by the SMO algorithm is highest of all in both the percentage split and k-folds cross validation method. The model developed using SMO classifier by k-folds cross-validation (k = 10) is acknowledged as a final model. This research focuses to develop a prediction model to predict and analyze the competency of project managers by applying a supervised machine learning approach. Seven extensively used algorithms (Naïve Bayes, SMO, multilayer perceptron, logistic, KStar, J48, random forest) are used to check the accuracy of models and an algorithm that gives the highest accuracy is adopted. Data collection for this research is carried out by expert opinion method to validate the characteristics (factors) essential for competent project managers in the first round and the description of each factor as high, medium and low is inquired with the same experts in the second round. After an expert opinion, a structured questionnaire is prepared for the survey to assess the competency level of project managers (PMs). The competency level of PMs working under government funded, foreign aided or private projects from the contractor’s side is measured. This research is limited to the medium scale construction projects of Nepal. This model can be a huge asset in the human resource department of construction companies as it helps to know the performance level of project managers in terms of “Higher than expected,” “Expected” or “Lower than expected” for the medium complexity construction projects of Nepal. Also, the model will assist human intelligence to make the decision while recruiting a new project manager/s for different types of projects at a time. Moreover, the model can be used for self-assessment of project manager/s to know their performance level. The model can be used to develop a user friendly interface system or an application such that it can be conveniently used anywhere any time. This research shows that most of the project managers working in a medium complexity construction project of Nepal are male, maximum of them hold bachelor’s degree and study for road projects. Furthermore, most of the project managers scored high in leadership skills, personal characteristics, communication skills, technical skills, problem-solving/coping with situation skills, team development and delegation and stakeholder/relationship management skills. The model has given the “Personal characteristics” attribute the highest weightage. Likewise, other attributes having high weightage are communication skills, analytical abilities, project budget, stakeholder/relationship management, team development and delegation and time management skills. This research was conducted to find the competency factors and to study the competency level of project managers in Nepal to develop a prediction model to predict the PM’s performance using a machine learning approach in medium scale construction projects. There is a lack of research to develop a model that predicts project manager’s competency using the machine learning approach. Therefore, the predictive model developed here helps in the identification of a competent project manager as it will be advantageous for project completion with a high success rate.

      Abstract: The key to green building (GB) success is to have GB expansion driven by consumer demand rather than enforced rules and regulations. Yet, only a few studies have focused on the market impediments to GB development. This study systematically identified and evaluated the critical impediments to the demand for green and sustainable architecture by construction clients in Ghana. The study adopted a two-stage data gathering approach. Qualitative data was collected first through an interview administered to 18 construction clients in Ghana. Based on the early findings, a survey instrument was subsequently developed to seek the views of 120 GB experts and professionals with 96 valid responses-returned. The study discovered that – ineffective advertisement of GB, the perceived cost of implementation, lack of expertise, lack of financial incentives, illiterate construction market and risk and uncertainties were the top six reasons for the low demand for GB by construction clients in Ghana Findings from this research would guide industry practitioners and stakeholders to make informed decisions regarding how to stimulate demand for GBs among construction clients. The paper models and presents contextual realities on barriers to GB demand in Ghana. The study has added to previous studies by unearthing what constitutes the lack of demand for sustainable architecture. The findings of this study are expected to provide valuable information and insight to policymakers to catalyze green construction by actively involving construction clients.

      Abstract: This study aims to assess the importance of transformational leadership competencies, as well as supply chain learning, to green innovation in construction at the supply chain level. A questionnaire survey is conducted to collect data from construction firms in Vietnam. Many statistical analysis methods – including the Shapiro-Wilk test, one-sample Wilcoxon signed-rank test and Kruskal-Wallis test – are performed to achieve the research objectives. The results indicate that the importance of most transformational leadership competencies is similarly perceived among different role groups (i.e. directors/deputy directors, project managers, consultants, quantity surveyors and designers). This study enriches the understanding of leadership research in construction at the supply chain level and also develops a theoretical framework for theory testing research, where the relationships of transformational leadership competencies and supply chain learning with green innovation are highlighted. Research on leadership in the green supply chain context is still limited, especially in the construction industry. Thus, this study is conducted to fill this gap of research.

      Authors: Paola Reyes Veras , Suresh Renukappa , Subashini Suresh
      Abstract: The construction industry, being one of the main activities in the ever-demanding need for technology developments, sometimes falls short of other industries in terms of implementation. The adoption of Big Data (BD) in industries such as health and retail has had positive impacts in aspects such as decision-making processes and forecasting trends that allow planning some future business movements. Hence, the question of whether these results can be imitated in the construction industry. Therefore, this paper aims to address the level of awareness identified as a first step towards implementation of the BD concept within the construction industry in the Dominican Republic (DR). As little to no information exist on the subject; the selected approach to perform this research was qualitative methodology; 21 semi-structured interviews were studied using situational awareness. Four levels of awareness were developed based on the Endsley’s Situation Awareness model. The results showed that nearly 95% of the interviewees had either no knowledge or very basic awareness of the BD requirements or intermediate awareness, but only 5% had applied BD concepts in the construction industry. This study shows the gaps that exist in the understanding and implementation of BD concepts in the DR construction industry. This paper establishes the need to develop continuous professional development programmes for construction professionals and a need to update curriculum in construction-related education.

      Abstract: The purpose of this paper is to report on the results of an exploratory study on the use of unmanned aerial vehicles (UAV) as a visual data collection tool in the architecture, engineering, construction and facility management industry for the inspection of pathological manifestations in building facades. The methodology used a field research experimental approach, where three case studies were carried out involving buildings of medium and high elevation. The protocol of activities included image collection and processing stages, as well as detailed analysis of the collected visual data for the identification of pathological manifestations in building facades. The findings emphasize the technical feasibility and efficacy of inspections with UAV, showing that among the visual assets produced, digital photographs collected with the aircraft were more effective for the detection of pathologies when compared to the three-dimensional models and orthomosaics generated by digital photogrammetry software. The research has formulated the protocol for the inspection of facades using UAV and the comparative analysis of visual assets that can be generated for inspection purposes.

      Authors: Dilani Niroshika Abeynayake , BAKS Perera , Chandanie Hadiwattege
      Abstract: Survival challenges compel construction firms to change their business thinking on adapting business models (BMs). Unlike in the other fields, in the construction field, it is still a novel concept, probably because BM adaptation in the industry has not been sufficiently studied. Hence, the purpose of this study is to set a roadmap for the effective adaptation of the BM concept in the construction industry. To develop a roadmap, this study analysed BM literature through a comprehensive literature review by finding the BM research development stages using studies done in other fields and locating construction industry BM literature. No stage-wise development of BM research has taken place in the construction industry. The four BM research development stages, namely, defining BMs, listing BM components, describing BM components and modelling BM components as a business model ontology (BMO) in relation to the construction industry have to be followed for proper BM adaptation in the construction industry. This study provided an overview of and a roadmap for BM adaptation in the construction industry for the benefit of future researchers. The proper adaptation of the BM concept through a BMO will enable construction business managers to easily innovate, design and change construction BMs to streamline their business thinking.

  • A smart objects library for BIM-based construction site and emergency
           management to support mobile VR safety training experiences

      Authors: Vito Getuli , Pietro Capone , Alessandro Bruttini , Tommaso Sorbi
      Abstract: Health and safety training via immersive virtual reality (VR) in the construction sector is still limited to few early adopters despite the benefits it could provide in terms of training effectiveness. To foster its adoption, in this work, the authors address the lack of an organized asset of digital contents dedicated to the production of VR site scenarios that emerged as one of the most limiting factors for the implementation of building information modeling (BIM) and VR for construction workers’ safety training. To improve this critically time-consuming process, a dedicated site object library is proposed. The development of the site object library for the production of BIM-based VR safety training experiences followed a four-step process: definition of the object list and categories from the analysis of heterogeneous knowledge sources – construction sectors’ regulations, case studies and site scenarios’ imagery; definition of the object requirements (e.g. information, graphics, sounds, animations and more); design of an object information sheet as a library implementation support tool; and library implementation and validation via collaborative VR sessions. This work provides the definition of a structured library of construction site objects dedicated to the production of VR scenarios for safety training comprising 168 items, implemented and validated. The research contributes to facilitate and standardize the time-consuming contents’ production and modeling process of site scenarios for VR safety training, addressing the lack of a dedicated site object library. Furthermore, the novel library framework could serve as a base for future extensions dedicated to other applications of VR site simulations (e.g. constructability analysis).

  • Enhanced model of the innovation-decision process, for
           modular-technological-process innovations in construction

    • Free pre-print version: Loading...

      Authors: Barry Gledson
      Abstract: The purpose of this study is to establish an enhanced model of the innovation-decision process (IDP), specifically for construction. As context, innovation diffusion theory (IDT) is concerned with explaining how some innovations successfully stick whilst others fail to propagate. Because theoretical models provide abstracted representations of systems/phenomena, established IDT models can help decision-making units with innovation-related sense-marking and problem-solving. However, these occasionally fail or require enhancement to represent phenomena more successfully. This is apparent whenever middle-range theory seems ill-fitted to the complexity of construction. Qualitative research via 13 semi-structured interviews occurred, with participants recruited via convenience and purposive sampling strategies. The study forms part of a broader mixed-method study (n = 246) informed by a research philosophy of pragmatism, investigating the applicability of classic IDT to the adoption of four-dimensional (4D) building information modelling (4D BIM) by the UK construction sector. This diffusion study resulted in the adaptation of an existing IDP model, ensuring a better contextual fit. Classified more specifically as a modular-technological-process innovation, 4D BIM with its potential to provide construction planning improvements is used as a vehicle to show why, for construction, an existing model required theoretical extensions involving additional stages, decision-action points and outcomes. This model can assist construction industry actors with future adoption/rejection decisions around modular-technological-process innovations. It also aids the understanding of scholars and researchers, through its various enhancements and by reinforcing the importance of existing diffusion concepts of compatibility and trialability, for these innovation types. An enhanced model of the IDP, specifically for construction, is established. This construction-centric contribution to IDT will be of interest to construction scholars and to practitioners.

      Authors: Karim Farghaly , William Collinge , Mojgan Hadi Mosleh , Patrick Manu , Clara Man Cheung
      Abstract: With the rapid development of digital information and modelling software applications for construction, questions have arisen about their impact on construction safety. Meanwhile, recognition that designers can help reduce risks involved in construction, operation and maintenance via a prevention through design (PtD) approach (also known as design for safety) highlights the significance of digital technologies and tools to PtD. Thus, this paper aims to provide a systematic review of a wide range of digital technologies for enhancing PtD. A five-stage systematic literature review with coding and synthesis of findings is presented. The review covers journal articles published between 2000 and 2020 related to the applications of various digital technologies, such as building information modelling (BIM), 4D, databases, ontologies, serious games, virtual reality and augmented reality, for addressing safety issues during the design phase in construction. Analysis of the articles yielded a categorisation of the digital applications for PtD into four main areas: knowledge-based systems; automatic rule checking; hazard visualization; and safety training for designers. The review also highlighted designers’ limited knowledge towards construction safety and the possibility to address this by using gaming environments for educating designers on safety management and using artificial intelligence for predicting hazards and risks during design stage in a BIM environment. Additionally, the review proposes other directions for future research to enhance the use of digital technologies for PtD. This paper contextualises current digital technology applications for construction health and safety and enables future directions of research in the field to be identified and mapped out.

      Abstract: This paper aims to study the effects of different weather conditions on typical concrete work tasks’ productivity. Weather is one important factor that has a negative impact on construction productivity. Knowledge about how weather affects construction works is therefore important for the construction industry, e.g. during planning and execution of construction projects. A questionnaire survey method is used involving means to perform pairwise comparisons of different weather factors according to the analytical hierarchical process (AHP). The survey also contains means to enable assessment of the loss in productivity for typical work tasks exposed to different weather types. The survey targets practitioners involved in Swedish concrete construction projects, and the results are compared with previous research findings. The survey covers responses from 232 practitioners with long experience of concrete construction. The pairwise comparisons reveal that practitioners rank precipitation as the most important followed by wind and temperature. The loss in productivity varies significantly (from 0 to 100%) depending on the type of work and the type of weather factor considered. The results partly confirm findings reported in previous research but also reveal a more complex relationship between weather and productivity indicating several underlying influencing factors such as type of work, type of weather (e.g. rain or snow) and the intensity of each weather factor. This paper presents new data about how 232 practitioners assess the effects of weather on construction productivity involving novel means to perform objective rankings such as the AHP methodology.

      Abstract: The purpose of this study is to develop a building information modelling (BIM)-based mixed reality (MR) application to enhance and facilitate the process of managing bridge inspection and maintenance works remotely from office. It aims to address the ineffective decision-making process on maintenance tasks from the conventional method which relies on documents and 2D drawings on visual inspection. This study targets two key issues: creating a BIM-based model for bridge inspection and maintenance; and developing this model in a MR platform based on Microsoft Hololens. Literature review is conducted to determine the limitation of MR technology in the construction industry and identify the gaps of integration of BIM and MR for bridge inspection works. A new framework for a greater adoption of integrated BIM and Hololens is proposed. It consists of a bridge information model for inspection and a newly-developed Hololens application named “HoloBridge”. This application contains the functional modules that allow users to check and update the progress of inspection and maintenance. The application has been implemented for an existing bridge in South Korea as the case study. The results from pilot implementation show that the inspection information management can be enhanced because the inspection database can be systematically captured, stored and managed through BIM-based models. The inspection information in MR environment has been improved in interpretation, visualization and visual interpretation of 3D models because of intuitively interactive in real-time simulation. The proposed framework through “HoloBridge” application explores the potential of integrating BIM and MR technology by using Hololens. It provides new possibilities for remote inspection of bridge conditions.

      Abstract: This study aims to thoroughly examine the trends and developments of crane layout planning (CLP) in the construction field and reveal future research directions for modular integrated construction (MiC). Through a rigorous systematic mixed-review methodology that integrates bibliometric, scientometric and qualitative analysis, this study explored the crane layout research trend; the scientometric analysis of journal sources and keywords occurrence network; the research contributions and links between influential countries; the classification of research articles based on the type of problems and solution approaches; the qualitative analysis of existing findings and research gaps; and the future research direction for CLP in MiC. This study found five categories under the CLP domain, namely, crane selection, crane location, integrated crane selection and location, integrated crane location and allocation of supply points and hybrid problems. The major research approaches used to solve CLP is optimization (43%), visualization (23%), decision support systems (16%), simulation (11%) and qualitative techniques (7%). The possible future research directions include artificial intelligence-based models, multi-crane locations, CLP for MiC re-use, dynamic models representing real-life scenarios and building information modeling-based virtual reality models. Through a mixed-review methodology, this study provides a comprehensive analysis of problem settings and solution methods of CLP while mitigating the subjectivity of traditional review methods. Also, it presents a repertoire on CLP and illuminates future directions for seasoned researchers in the context of MiC.

      Authors: Martin Lennartsson , Samuel André , Fredrik Elgh
      Abstract: The purpose of this research is to support the customization ability for industrial house building companies striving to offer individualized products but with a strategy which includes a production facility. This is accomplished by analyzing the as-is state in terms of existing engineering assets and by proposing a to-be state using the design platform and product lifecycle management (PLM) support. This study is based on design research methodology and collected data are in-depth interviews, document reviews and workshops and method development. The theoretical baseline is product platforms and the design platform. The analysis showed that despite use of a platform, inherent assets are disorganized. Still, the identified object-based engineering assets were possible to include in a conceptual proposal for better management, both in the process and product view, using an asset relationship matrix and a PLM system. The results should be applicable for industrial house building and off-site construction companies and offers an approach to identify and manage their assets and platforms which are crucial to stay competitive. Previous research on design platforms has focused on engineer-to-order companies within the mechanical industry. The contribution of this paper lies in the application and support of the design platform for industrial house building and the introduction of PLM system support.

      Authors: Hyun Jeong Koo , James T. O’Connor
      Abstract: In recent decades, professionals in the architecture, engineering and construction industry have come to recognize building information modeling (BIM) as one of the most powerful technologies available to ensure successful project outcomes. The purpose of this paper is to explore the benefits of BIM on design defect prevention during the design phase of building projects. The authors qualitatively analyzed 160 design defect leading indicators (LIs) to identify key themes for design defect prevention. Then, by matching appropriate BIM functionalities to each key LI theme, they identified BIM-supported key LI themes. The result of this paper served as the foundation of a BIM-based key design processes framework, which identifies the necessary data, project parties, actions and applicable BIM functions for preventing particular design defects. In addition, the authors found that BIM implementation can benefit 71.2% of the LIs of the design defects associated with problematic deliverables. This study establishes the current state of BIM use for design defect prevention and also gives practitioners precisely targeted guidelines for using BIM functions during the design phase for better quality management.

      Abstract: This study aims to evaluate enterprise technology innovation capability in prefabricated construction (PC) from an input-output perspective, using six integrated enterprises in China as cases. An evaluation system for enterprise technology innovation capability in PC was constructed, including total input, technology output (TO) and project output. All the evaluation indexes were quantified, and the subject and object indexes weights were determined using the fuzzy cognitive map and information entropy, respectively. The final scores and ranks were evaluated through gray relational analysis (GRA) based on the combined weights. It was found that enterprise technology innovation capability in PC was low in China, with its unbalanced development in different dimensions and the poorest performance in TO, currently. This research has developed an evaluation system for technology innovation capability in PC at the enterprise level and scientifically quantified all the indexes, which is a breakthrough over existing studies. The GRA model based on the combined weights proposed in this study can be applied to other comparable fields and regions, with its easy operation.

      Abstract: This study aims to explore DroneSim, a virtual reality (VR)-based flight training simulator, as an alternative for real-world drone-mediated building inspection training. Construction, engineering and management students were asked to pilot drones in the VR-based DroneSim space and perform common flight operations and inspection tasks within the spatiotemporal context of a building construction project. Another student group was also recruited and asked to perform a similar building inspection task in real world. The National Aeronautics and Space Administration (NASA)–Task Load Index (TLX) survey was used to assess students’ inflight workload demand under both Real and DroneSim conditions. Post-assessment questionnaires were also used to analyze students’ feedback regarding the usability and presence of DroneSim for drone building inspection training. None of the NASA–TLX task load levels under Real and DroneSim conditions were highly rated by students, and both groups experienced comparable drone-building inspection training. Students perceived DroneSim positively and found the VR experience stimulating. This study’s contribution is twofold: to better understand the development stages involved in the design of a VR-based drone flight training simulator, specifically for building inspection tasks; and to improve construction students’ drone operational and flight training skills by offering them the opportunity to enhance their drone navigation skills in a risk-free, repeatable yet realistic environment. Such contributions ultimately pave the way for better integration of drone-mediated building inspection training in construction education while meeting industry needs.

      Abstract: The construction industry (CI) is known for heavy workloads and long working hours. Consequently, quantity surveyors (QSs) find it difficult to integrate work with life. Thus, the purpose of this study was to identify the causes and consequences of poor life management (LM) in both female and male QSs working for contractors at construction sites and strategies that would improve the LM of the QSs. The study adopted a mixed research approach by conducting semi-structured interviews and a questionnaire survey to identify the significant causes and consequences of poor LM in QSs and strategies that would improve the LM of the QSs. Manual content analysis and mean weighted rating (MWR) were used to analyze the collected data. Heavy workloads are the most significant cause of poor LM in QSs. The study found that male QSs are highly addicted to substance use and that female QSs lose sleep because of poor LM. Teamwork is the most significant strategy that would enhance the LM of both female and male QSs working at sites. The traditional work–life balance refers to the harmony between work and non-work lives of an individual. LM is associated with five spheres of life: work, family life, health, social life and spiritual life. Given that, to the best of the authors’ knowledge, no previous studies have focused on LM, this study becomes significant because it identifies the causes and consequences of poor LM of QSs working in the CI and the strategies that would enhance the LM of the QSs.

      Authors: Ibrahim Yahaya Wuni , Geoffrey Qiping Shen , Amos Darko
      Abstract: Industrialized construction (IC) leverages manufacturing principles and innovative processes to improve the performance of construction projects. Though IC is gaining popularity in the global construction industry, studies that establish the best practices for implementing IC projects are scarce. This study aims to benchmark practical lifecycle-based best practices for implementing IC projects. The study used a qualitative research design where nine IC cases from Australia, Singapore and Hong Kong were analysed to identify best practices. The methodological framework of the study followed well-established case study research cycle and guidelines, including planning, data collection, data analysis and reflection on findings. The study identified and allocated key considerations, relevant stakeholders, best practices, typical deliverables and best indicators to the different construction lifecycle phases of IC projects. It also developed a lifecycle-based framework of the best practices for IC projects. The study provides practitioners with practical insight into how best to effectively implement, manage and evaluate the performance of the IC project lifecycle phases. The proposed framework can serve as a practical diagnostic tool that enables project partners to evaluate the performance upfront progressively and objectively in each project lifecycle phase, which may inform timely corrective actions. The study’s novelty lies in developing a framework that identifies and demonstrates the dynamic linkages among different sets of best practices, typical outputs and best practice indicators across the IC project lifecycle phases.

      Authors: Sami Wasef Abuezhayeh , Les Ruddock , Issa Shehabat
      Abstract: The purpose of this paper is to investigate and explain how organizations in the construction sector can enhance their decision-making process (DMP) by practising knowledge management (KM) and business process management (BPM) activities. A conceptual framework is developed that recognises the elements that impact DMP in terms of KM and BPM. The development of this framework goes beyond current empirical work on KM in addition to BPM as it investigates a wider variety of variables that impact DMP. A case study is undertaken in the context of the construction industry in Jordan. A theoretical framework is developed and assessment of the proposed framework was undertaken through a questionnaire survey of decision-makers in the construction sector and expert interviews. The outcomes of this research provide several contributions to aid decision-makers in construction organizations. Growth in the usage of KM and BPM, in addition to the integration between them, can provide employees with task-related knowledge in the organization’s operative business processes, improve process performance, promote core competence and maximise and optimise business performance. Through the production of a framework, this study provides a tool to enable improved decision-making. The framework generates a strong operational as well as theoretical approach to the organizational utilization of knowledge and business processes.

  • Conceptual framework of value management adoption in the Nigerian
           construction industry

    • Free pre-print version: Loading...

      Authors: Lekan Damilola Ojo , Deji Rufus Ogunsemi , Olusola Ogunsina
      Abstract: The Nigerian construction industry is bedeviled with poor project performance and outcomes which value management (VM) could address if applied. The application of VM on Nigerian construction projects is very minimal due to certain obstacles, namely, lack of VM experts, paucity of knowledge on the techniques, etc., which inhibits the adoption into the construction industry. Therefore, this study aims to develop a conceptual framework of the adoption of VM on construction projects in a typical developing economy. This study engaged 15 selected VM experts in two rounds of Delphi survey to develop a conceptual framework of VM adoption. The method of data analysis includes mean score, standard deviation, Kendall’s coefficient of concordance, chi-square (χ2) test, interrater agreement analysis and significant level analysis. The developed conceptual framework was sent to a team of local and international VM experts for validation. This study reveals that the adoption of VM requires the collective effort of relevant stakeholders in the construction industry. The framework developed presents individual and collective activities to be undertaken by the stakeholders. The activities include training, legislation, government-funded research, etc. Thus, the adoption of innovative management methodology like VM requires the collaboration of academics, construction professional bodies and government parastatals. This will assist in the judicious use of limited construction resources and boost the relevance of the Nigerian construction industry among developing nations and in the global construction market. This study used the opinions of few construction professionals that can be regarded as VM experts in Nigeria, as against engaging a pool of construction professionals who may not be knowledgeable in VM process. Engaging the few VM experts in the Nigerian construction industry is important to have a valid basis for drawing conclusion, as large questionnaire survey could be possibly filled by inexperienced or unqualified respondents if stringent criteria are not considered at the outset of this study.

      Authors: Nor’Aini Yusof , Kong Seng Lai , Amy Marisa
      Abstract: As innovation has been recognised as important in improving construction company performances, this study aims to determine the effects of client focus and company type on innovation and company financial performances. A self-administered questionnaire was sent to 300 architectural and contractor companies and 163 (54.3%) were returned. The questionnaire data were analysed using a partial least squares structural equation modelling. Client focus was found to have a complementary partial mediation effect on the relationships between innovation and company financial performance and that innovation independently affected company financial performance with the influence being stronger in the architecture companies than in the contractor companies. The study adopted a broad definition for innovation without considering the innovation types. As different types of innovation require distinct knowledge, skills, capabilities and management practices, future studies could investigate the various types of innovation and their effects on financial performance. The findings provide valuable suggestions for principals, top management and policymakers on the importance of client focus when developing and disseminating innovation within the company. Also, architecture companies should focus on implementing innovation to stay competitive. The mediating effects of client focus and the moderating effects of company type were simultaneously analysed on the relationship between innovation and financial performance.

      Authors: Kwadwo Oti-Sarpong , Erika Anneli Pärn , Gemma Burgess , Mohamed Zaki
      Abstract: Government initiatives to improve construction have increasingly become more focused on introducing a repertoire of technologies to transform the sector. In the literature on construction industry transformation through policy-backed initiatives, how firms will respond to the demands to adopt and use innovative technologies and approaches is taken for granted, and there is scarcely any attention given to the institutional implications of transformation agenda. The purpose of this paper is to discuss these gaps and offer directions for future research. Following a synthesis of literature on the UK’s industry transformation agenda, the authors use the concepts of institutional logics, arrangements, complexity and strategic responses to suggest seven research questions that are at the nexus of policy-backed transformation and institutional theory. In this paper, the authors argue that increasing demands for the adoption and use of digital technologies, platforms, manufacturing approaches and other “industry-4.0”-related technologies will reconfigure existing logics and arrangements in the construction industry, creating a problem of institutional complexity for general contracting firms in particular. The questions are relevant for our understanding of the nature of institutional complexities, change, strategic firm responses, field-level dynamics and implications for the construction industry in relation to the transformation agenda. This paper is positioned to spur future research towards exploring the consequences of industry transformation through the lens of institutional theory.

  • An early-stage project complexity assessment tool for the AEC industry

    • Free pre-print version: Loading...

      Authors: Paulo Vaz-Serra , Peter Edwards , Guillermo Aranda-Mena
      Abstract: Complex projects require careful management. They may expose stakeholders to greater risks and place additional demands upon resources. In the initial stages of project development, however, little may be known about the nature and magnitude of such complexity. This paper aims to ensure that this gap is at least subjectively assessed and addressed. Research, using focus group workshops with a convenience sample of construction professionals, was carried out to test the validity of a Project Early Stage Complexity Assessment Tool (PESCAT). The PESCAT concept brings together selected complexity theories and uses subjectively based measures for assessment. The findings confirm that an early-stage project complexity assessment tool is practicable and can contribute to project management practice in the construction industry. It should be applied by individual project stakeholders using small teams of experienced staff. PESCAT explores project complexity through “filter” sets of perspective factors which should be customised to reflect the stakeholder’s role and processes in a project. In the initial complexity assessment model, resolution space and uncertainty were tested as project complexity parameters. However, in subsequent versions of the tool, four measures (differentiation and differentiation uncertainty; interdependency and interdependency uncertainty) are used in an innovative way that focuses users’ attention more clearly and points to a more targeted approach for addressing project complexity. The value of our model lies in its practical application and the project management benefits it can deliver.

      Authors: Caleb Debrah , De-Graft Owusu-Manu
      Abstract: The purpose of this study is to develop a framework to guide green cities development in developing countries. The study adapted and validated indicators that can be adopted, to predict, estimate, depict and measure green city development in developing countries. In using a covariance-based structural equation model (CBSEM), the study developed a framework for green cities development in developing countries using Kumasi city (Ghana) as a case study. To test the proposed framework, a quantitative methodology was used, in which, data was collected using research questionnaires that targeted a sample of 200 green city experts. In total, 154 useable questionnaires were retrieved, representing a response rate of 77%. The confirmatory and exploratory factor analyses were adopted in a CBSEM. The indices reported were indicative that the model/framework is a good fit for the data. This points to the direction that the model for measuring green city development was statistically significant and acceptable. The results of the confirmatory factor analysis revealed a robust fit of the indices, as they met the standardised cut-off points and as such the model fits the data. This novel research is one of the few studies investigating green cities development in Ghana which could serve as a lesson for other developing countries. The proposed green city framework will serve as a guide to stakeholders in identifying the key indicators/factors that are critical to green city development in developing countries, especially Ghanaian cities. This study proposed a green city framework to guide the development of green cities based on the local context of Ghana.

      Abstract: The purpose of this paper is to study the design process innovations that enabled the successful delivery of a hybrid, mass-timber high-rise building in Canada, the Brock Commons Tallwood House at the University of British Columbia. It is one of a set of papers examining the project, including companion papers that describe innovations used during the mass timber construction process and the impact of these innovations on construction performance. A mixed-method, longitudinal case study approach was used in this research project to investigate and document the Tallwood House project over a three-year period. Both quantitative and qualitative data collection and analysis techniques were used. Graduate student researchers were embedded within the project team to observe meetings and decision-making and to conduct periodic interviews. The research highlights a case of a balanced triple-helix system that provided a context for the successful “clustering” of product and process innovation, which were developed and implemented to flow throughout the project’s lifecycle and across its supply chain to provide benefits at each stage. Four significant process-based innovations were implemented at the design phase of the building project to support radical product innovation: an integrated design process, virtual design and construction, designing for manufacturing and assembling and a rigorous quality control and quality assurance process. The product innovations developed through these process innovations were the structural system and the prefabricated envelope system. The context of innovation was seen to allow this “clustering,” which is believed to be a key condition of success and enabled the efficient and successful delivery of the project. Generally, the approach was successful; however, some factors including the number of stakeholders and good-faith collaboration may limit the replicability of these strategies. This paper presents an in-depth investigation into the instantiation of an innovation system, identified as a balanced triple-helix system, which enabled and facilitated the design and decision-making process for a radical product innovation. Moreover, this paper describes the deployment of a “cluster” of process innovations that flowed throughout the project’s lifecycle and across the project supply chain. This was seen as a key factor in ensuring the successful delivery of the project.

  • Achieving construction innovation in best value procurement projects: New
           Zealand mega projects study

    • Free pre-print version: Loading...

      Authors: Fei J. Ying , Nan Zhao , John Tookey
      Abstract: Best value procurement (BVP) has been recognized for some time as offering significant opportunities to advance process excellence in the construction sector. As an innovative approach to strategic procurement, BVP has attracted attention from the New Zealand (NZ) Government. It has similarly been found that the most substantial benefit of this modified approach to procurement is in value creation and innovative organizational processes through identifying “best value.” Yet to date, there is a lack of robust evidence as to how BVP can exactly influence construction innovation. Accordingly, this paper aims to explore how to improve BVP implementation to promote construction innovation and what are the values to be achieved in BVP mega projects from the view of innovation. Semi-structured interviews with 22 participants, including project managers, procurement specialists, engineers and general managers from three organization types, were conducted to explore BVP implementation in a range of mega construction projects in NZ. Barriers to BVP implementation and value innovation have been identified in this paper. Data analysis suggested traditional mindset in the procurement process, market constraints, mistrusts and fuzzy definition of BVP are the challenges for BVP implementation; BVP cultivates organizational competition because of diverse collaboration models and value attitudes; and BVP considers more values from the whole supply chain. To promote innovative construction, existing BVP should consider adopting progressive enhancements toward updating procurement guidance, encouraging effective communications, collaborating and promoting changes in stakeholders’ mindset. Identified barriers to BVP implementation set up a platform for framing guidance, which could provide an effective approach as it enables a better understanding of what BVP means to NZ and what needs to be overcome. Taking this into account, similar small size markets around the world would be able to consider the applicability of BVP for innovative improvements. This paper provides insights into value concepts in project procurement. It theoretically and practically possesses originality in linking BVP to innovative construction. The study of BVP and its application further reveals the importance of establishing a distinct regulation and fostering organizational competition from value aspects to achieve construction innovation.

  • Application of semantic Web ontologies for the improvement of information
           exchange in existing buildings

    • Free pre-print version: Loading...

      Authors: Farhad Sadeghineko , Bimal Kumar
      Abstract: Facilitating the information exchange and interoperability between stakeholders during the life-cycle of an asset can be one of the fundamental necessities for developing an enhanced information exchange framework. Such a framework can also improve the successful accomplishment of building projects. This paper aims to use Semantic Web technologies for facilitating information exchange within existing building projects. In real-world building projects, the construction industry’s information supply chain may initiate from near scratch when new building projects are started resulting in diverse data structures represented in unstructured data sources, like Excel spreadsheets and documents. Large-scale data generated throughout a building's life-cycle requires exchanging and processing during an asset's Operation and Maintenance (O&M) phase. Building information modelling (BIM) processes and related technologies can address some of the challenges and limitations of information exchange and interoperability within new building projects. However, the use of BIM in existing and retrofit assets has been hampered by the challenges surrounding the limitations of existing technologies. The aim of this paper is twofold. Firstly, it briefly outlines the framework previously developed for generating semantically enriched 3D retrofit models. Secondly, a framework is proposed focussing on facilitating the information exchange and interoperability for existing buildings. Semantic Web technologies and standards, such as Web Ontology Language and existing AEC domain ontologies are used to enhance and improve the proposed framework. The proposed framework is evaluated by implementing an example application and the Resource Description Framework data produced by the previously developed framework. The proposed approach makes a valuable contribution to the asset/facilities management (AM/FM) domain. It should be of interest to various FM practices for existing assets, such as the building information/knowledge management for design, construction and O&M stages of an asset’s life-cycle.

      Abstract: The relatively low capital cost and contributions to mitigating global warming have favoured the continuous construction and operation of nuclear power plants (NPPs) across the world. One critical phase in the operation of nuclear plants for ensuring the safety and security of radioactive products and by-products is decommissioning. With the advent of digital twinning in the building information modelling (BIM) methodology, efficiency and safety can be improved from context-focus access to regulations pertaining to demolition of structures and the cleaning-up of radioactivity inherent in nuclear stations. The purpose of this study, therefore, is to propose a BIM-driven framework to achieve a more regulation-aware and safer decommissioning of nuclear power plants. The framework considers task requirements, and landscape and environmental factors in modelling demolition scenarios that characterise decommissioning processes. The framework integrates decommissioning rules/regulations in a BIM linked non-structured query system to model items and decommissioning tasks, which are implemented based on context-focussed retrieval of decommissioning rules and regulations. The concept’s efficacy is demonstrated using example cases of digitalised NPPs. This approach contributes to enhancing improvements in nuclear plant decommissioning with potential for appropriate activity sequencing, risk reduction and ensuring safety. A BIM-driven framework hinged on querying non-structured databases to provide context-focussed access to nuclear rules and regulations and to aiding decommissioning is new.

      Abstract: This paper aims to present factors affecting the Indian construction organisations in adopting off-site construction (OSC) methods. An existing readiness maturity model has been used to assess three large organisations in different parts of India. A case study methodology has been adopted in this paper to highlight critical issues in OSC adoption in India. This paper presents three case studies and concludes the Indian construction sectors readiness to adopt the OSC methods. Through the case studies, different issues related to the adoption of OSC have been identified and highlighted for the Indian construction sector. Although the three companies are large, there are several small- and medium-sized enterprises (SME) operating in India's construction sector, and future research shall be needed to review these SMEs. This research study is broadly focused on developing and assessing an OSC readiness framework for Indian construction organisations. The research scope and the population for data collection are limited to large construction organisations in India only. The proposed OSC readiness maturity model guides construction practitioners in India through a structured process to assess their OSC readiness in the market. This assessment enables them to evaluate and benchmark their processes through the strategic and operational phases. This research will add to the existing knowledge of OSC in India by mapping issues relevant to India's construction industry. The research has provided background on the status of OSC, the drivers and barriers affecting the implementation of OSC techniques in the Indian construction industry. Through the three case studies, several factors related to the implementation of OSC methods have been identified and highlighted within the Indian construction sector. Although the model has been applied to the Indian construction sector, it can easily be modified to fit into other areas and similar dynamics and business conditions.

      Abstract: The purpose of this paper is to investigate building information modelling (BIM) integrated Internet of Things (IoT) architectures extensively and provide comparative evaluation of those against deciding parameters pertaining to their characteristics and subsequent applications in construction industry. This paper identifies BIM-integrated cyber physical system frameworks, specific to project objectives, comprising of sensors working as physical assets and BIM-based virtual models acting as the cyber component , connected via wired or wireless protocols (e.g. WiFi, Zigbee, near-field communication, mobile-to-mobile, Zwave, 3 G, 4 G, long-term evolution, 5 G and low-power wide-area networks) and their potential applications in decision-making, visual management, logistics and supply chain management, smart building system management and structural performance assessment, etc. Such proposed architectures are evaluated against deciding parameters such as availability, reliability, mobility, performance, management, scalability, interoperability and security and privacy to evaluate their respective efficiencies. This study finds that the underlying aim of planned IoT frameworks is to integrate systems and processes for a better information flow and to initiate shift from silo solutions to a smart ecosystem. The efficiencies of such frameworks are completely subjective to their respective project natures, objectives and requirements. This study is unique in its nature to identify requirements of an efficient BIM-integrated IoT architecture and provide comprehensive insights about potential applications in construction industry.

      Authors: Seyedeh Neda Naghshbandi , Liz Varga , Yukun Hu
      Abstract: The development of communication and artificial intelligence technologies has raised interest in connectivity and increased autonomy of automated earthmoving equipment for earthwork. These changes are motivating work to reduce uncertainties, in terms of improving equipment object detection capability and reducing strikes and accidents on site. The purpose of this study is to illustrate industrial drivers for automated earthwork systems; identify the specific capabilities which make the transformation happen; and finally determine use cases that create value for the system. These three objectives act as components of a technology roadmap for automated and connected earthwork and can guide development of new products and services. This paper used a text mining approach in which the required data was captured through a structured literature review, and then expert knowledge was used for verification of the results. Automated and connected earthwork can enhance construction site and its embraced infrastructure, resilience by avoiding human faults during operations. Automating the monitoring process can lead to reliable anticipation of problems and facilitate real-time responses to unexpected situation via connectedness capabilities. Research findings are presented in three sections: industrial perspectives, trends and drivers for automated and connected earthwork; capabilities which are met by technologies; and use cases to demonstrate different capabilities. This study combines the results of disintegrated and fragmented research in the area of automated and connected earthwork and categorises them under new capability levels. The identified capabilities are classified in three main categories including reliable environmental perception, single equipment decision-making toward safe outcomes and fleet-level safety enhancement. Finally, four different levels of automation are proposed for earthwork technology roadmap.

      Abstract: The purpose of this paper is to present a new method for project tracking and control of integrated offsite and onsite activities in modular construction considering practical characteristics associated with this type of construction. The design embraces building information modelling and integrates last planner system (LPS), linear scheduling method (LSM) and critical chain project management (CCPM) to develop tracking and control procedures for modular construction projects. The developed method accounts for constraints of resources continuity and uncertainties associated with activity duration. Features of proposed method are illustrated in a case example for tracking and control of modular projects. Comparison between developed schedule and Monte Carlo simulation showed that baseline duration generated from simulation exceeds that produced by developed method by 12% and 10% for schedules with 50% and 90% confidence level, respectively. These percentages decrease based on interventions of members of project team in the LPS sessions. The case example results indicate that project is delayed 5% and experienced cost overrun of 2.5%. Developed method integrated LPS, LSM and CCPM while using metrics for reliability assessment of linear schedules, namely, critical percent plan complete (PPCcr) and buffer index (BI). PPCcr and BI measure percentage of plan completion for critical activities and buffer consumption, respectively. The developed method provides a systematic procedure for forecasting look-ahead schedules using forecasting correction factor Δt and a newly developed tracking and control procedure that uses PPCcr and BI. Quantitative cost analysis is also provided to forecast and monitor project costs to prove the robustness of proposed framework.
