Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose It is widely recognized that large-scale public–private partnership (PPP) projects require an effective coordination mechanism among various stakeholders throughout the project life cycle. The purpose of this paper is to provide an insight into how this may be achieved through the leading small group (LSG), which is a distinctive informal Chinese institution for coordination among various public agencies. Design/methodology/approach An in-depth case study using secondary data and five in-depth interviews with two staff members from the developer and three government officials involved is used to probe into how the LSG functions during the various development phases of the Yangzhou Teda Waste-to-Energy project. Findings The main finding is that, conditional on its capacity, the LSG coordinated various public agencies to promote fast project implementation and ensure its smooth operation by making high-level decisions, facilitating quick permits and approvals, and mitigating the risks. However, formalization and participation from other stakeholders are needed to ensure good governance. Research limitations/implications Because it is an exploratory case study, the findings cannot be readily generalized. Further research can be done to compare the performance of LSGs in different Chinese cities and PPP projects. Practical implications It is supposed that this paper can provide implications of designing effective coordination mechanisms for managing large-scale PPP projects. Originality/value This paper provides an account of the LSG as a distinctive Chinese coordination mechanism that has been rarely studied.

Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose The purpose of this paper is to deal with the maximum interest rate guarantees (MIRGs), and develop a methodology for setting the optimal value of the interest rate cap, namely the maximum interest rate above which the private investor will obtain reimbursement from the government, which balances the interests of the parties involved in the project. Design/methodology/approach The mechanism underlying the MIRG is modeled through real options. Monte Carlo simulation is employed as the option-pricing method. The resulting real option-based model is applied to the case of the “Camionale di Bari” toll road (Southern Italy). Findings The application provides some insights for the policy maker called to define the proper forms of guarantees. Furthermore, the results support the negotiation process, allowing the different actors to structure the guarantee in a way that satisfies all the parties and fairly allocates risks between them according to different operational and financial conditions. Originality/value The novelty of the contribution is triple. First, the authors advance the state of the art on government supports by focusing on the interest rate guarantee. Second, the authors enrich the existing studies on MIRG by proposing a quantitative model to set the guarantee in compliance with the public–private win-win principle. The developed real option-based model supports the decision maker in finding the optimal value of the interest rate cap, which is able to satisfy the interests of the parties involved in the project. Third, the authors consider not only the private sponsor and the government, as traditionally made by the models developed for other guarantees, but also the lender.

Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose The purpose of this paper is to establish a conceptual framework to assist decision makers in identifying an appropriate decision-supporting method (DSM) to evaluate public-private partnership (PPP) contract types in a disciplined and systematic manner. Design/methodology/approach A systematic literature review was conducted to compare and analyse DSMs in construction procurement processes, and explore the benefits and limitations of using DSMs. A conceptual framework is then developed to accommodate client characteristics when selecting DSM in a PPP context. An example was obtained to illustrate the implementation of the proposed framework. Findings DSMs employed in the procurement method selection are identified by using a systemic literature review. The benefits and limitations of each DSM are established and comparisons of DSMs are provided to fit the client characteristics and a conceptual framework is developed to assist decision makers in choosing DSM for contract selection. Originality/value This paper demonstrates a link between DSMs and PPP contracts which adds value at the stage of PPP contract evaluation. Also, the proposed framework sheds some light on an important aspect of the public sector to consider the improvement of current policies (PPP framework/guideline).

Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose Cultural differences cause conflicts amongst construction project participants, deterring the success of projects. Understanding such different cultural manifestations could help the removal of the misunderstandings amongst sub-cultural groups and removal of formal irrationalities deterring the progress of construction projects. The purpose of this paper is to explore the nature of project cultures in the public sector construction projects. Design/methodology/approach An exploratory case study was selected as the research strategy to achieve the research aim. Three public sector building construction projects were used as case studies. Nine semi-structured interviews and observation of two progress review meetings per case were used for data collection. Findings As per the research findings, contractors believed that construction project culture emerged and transferred through continuous interactions and socialisations with time. Consultants believed that culture was emerged focusing on clearly defined project objectives. In addition, all members assumed that project members at high authority levels were contributing more for the emergence and transfer of cultural aspects. Levels of culture and power existed within the public sector project culture as clients with the highest power, consultants the next and contractors with the least power. Public sector project culture was not leader centred. Shared behavioural norms were not much popular in project culture. Highly differentiated behavioural norms, demonstrating clear professional sub-cultures for the client, contractor and consultant, were available. Originality/value The research findings are helpful to construction project managers to enhance the level of motivation, productivity, commitment, continuous interactions and socialisations of project participants and to avoid any negative outcomes in behaviours.

Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose The Low carbon (LC) agenda has captured interest across governments and research communities. But such focus is not addressed so far in the operation of municipal solid waste (MSW) infrastructure in India. The purpose of this paper is to draw focus on the promotion of low carbon infrastructure by improving the procurement process of the public–private partnership (PPP) approach. Design/methodology/approach The current study employed a case study methodology. This paper develops and validates a “five-fold framework,” comprising of selection, financial, operational, standards and targets measures, for integrating LC principles in the procurement of infrastructure projects. Findings The public sector fails to understand the importance of the need to incorporate climate change mitigation strategies due to poor procurement competencies. With respect to the operationalization of the framework, funding of viability gap in operations instead of construction, allowing renegotiation clauses to cater possible future LC technological improvements and incorporating emission reduction targets at the local and national levels were highlighted. Research limitations/implications LC principles presented in this paper are not exhaustive and are verified using a single Indian PPP case. Future research endeavor can focus on the relevancy and operationalization of these principles using a more elaborate set of indicators and extend the study to other sectors and countries. Originality/value This paper seeks to act as guidelines for governments on how to create and improve LC MSW PPP infrastructure projects to facilitate simultaneous achievement of both climate change mitigation and infrastructure delivery goals. The current study could add value to the current emphasis on LC transitions by policymakers, government agencies and regulators.

Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose The purpose of this paper is to identify the carbon intensive building elements or “carbon hotspots” of office buildings in order to maximise the carbon reduction potential during design stages. Design/methodology/approach Embodied carbon (EC) estimates of 28 office buildings in the UK were obtained and carbon hotspots of the sample (in accordance with the new rules of measurement (NRM) element classification) were identified using the 80:20 Pareto principle. Findings Frame, substructure, external walls, services and upper floors were identified as carbon hotspots of the selected sample. However, findings do not support the 80:20 ratio in this case but propose a ratio of 80:36. Stairs, internal walls and partitions, internal doors, wall finishes, ceiling finishes and fittings and furnishings were identified as carbon insignificant elements that have a lower EC reduction potential compared to the rest. Research limitations/implications The findings are applicable to office buildings in the UK but the methodology is adaptable to different types of buildings in other countries. Originality/value Findings unveil carbon intensive and carbon insignificant building elements of typical office buildings in the UK. This informs designers of the elements that could yield the highest potential EC savings via effective design choices. In addition, a logical design timeline is proposed for building elements based on their element hotspot category and design sequence to assist design decision making.

Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose The purpose of this paper is to discuss policy-relevant findings regarding strategies for mainstreaming gender in achieving sustainable post-disaster reconstruction (PDR). Design/methodology/approach An exploratory case study was used to explore the implementation of gender mainstreaming strategies and the link to sustainable PDR. The Bantul and Sleman regencies of Yogyakarta province provide a unique site for researching PDR as they are located in a region that is more strongly affected by earthquakes than nearly any other in Indonesia. Data were collected through interviews with 17 key stakeholders and 26 beneficiaries who were involved during and after the earthquake. To support the interview findings, surveys involving 50 policy makers and 150 beneficiaries were conducted. Content analysis and t-statistics were used in analyzing the data. Findings Gender mainstreaming strategies within sustainable reconstruction should incorporate strategies for protecting against gender vulnerabilities and for promoting gender capacities. Both are fundamental to the achievement of sustainable PDR. Originality/value The paper establishes comprehensive strategies for mainstreaming gender under three pillars (i.e. economic, social and environmental) of sustainable development. The findings benefit relevant policy makers by improving the policy performance of gender mainstreaming in the affected communities in enhancing sustainable PDR.

First page: 334 Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose The purpose of this paper is to build upon the extensive application of risk registries in the construction literature and establish a systematic methodology to develop risk registries. Risk registries channel judgment of experts as a basis for risk analysis and should be tailored for each project to be more effective. Given their prevalence, there is a need for systematic integration of tacit and explicit knowledge to develop practical risk registries. Design/methodology/approach A combined approach is proposed using the systematic literature review (SLR) technique to integrate explicit knowledge and Delphi technique to integrate tacit knowledge in the development of risk registries. This two-step approach further increases the robustness of the registries by validating them through integrating and contrasting multiple forms of knowledge for a tailored risk registry. Findings The application of the proposed approach indicates that the use of multiple forms of knowledge can increase the robustness and practicality of risk registries. It also showcased its potential in the development of risk registries for complex projects. Examples include modification of risk factors obtained from the explicit sources of knowledge based on contextual tacit knowledge. Originality/value The proposed approach is an imperative step to standardize the development of risk registries. With its inherent validation process through integrating and contrasting tacit and explicit knowledge, practitioners can use this approach to develop practical risk registries for different categories of projects. Integrating different forms of knowledge can increase the impact of registries beyond risk assessment and in contexts such as decision making and performance assessment.

First page: 348 Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose The purpose of this paper is to develop a conceptual cost estimation (CCE) model for building project by using a pragmatic approach, which is a mix of tools drawn from multiple regression analysis (MRA) and adaptive neuro-fuzzy inference system (ANFIS), to improve the accuracy of cost estimation at an early stage. Design/methodology/approach This paper presents a set of MRA and integrating MRA with ANFIS or MRANFIS. A simultaneous regression analysis was developed to determine the main cost factors from 12 variables as input variables in the ANFIS model. Cost data from 78 projects of state building in West Sumatra, Indonesia were used to indicate the advantages of the proposed model. Findings The result shows that the proposed model, MRANFIS, has successfully improved the mean absolute percent error (MAPE) by 2.8 percent from MRA of 10.7–7.9 percent for closeness of fit to the model data and by 3.1 percent from MRA of 9.8–6.7 percent for prediction performance to the new data. Research limitations/implications Because the significant variables are different for each building type, the model may be not appropriate for other buildings depending on the characteristics of building. The models can be used and analyzed based on the own historical project data for each case so that the model can be applied. Originality/value The study thus provides better accuracy of CCE at an early stage for state building projects in West Sumatra, Indonesia by using the integrated model of MRA and ANFIS.

First page: 358 Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose A section of project management literature attributes overruns to estimators’ deceit and delusion. An example of this is Flyvbjerg’s theorisation of strategic misrepresentation and optimism bias. To show that such a notion is not true entirely, the study elicits evidence relating to how costs of projects often fluctuate erratically as prices of construction materials change throughout contract cycle times. The purpose of this paper is to examine the causal relationships between persistent changes in prices of construction materials and project’s outturn costs. Design/methodology/approach The authors obtained and analysed price data of construction materials published in a Nigerian national daily in the 16 years between 2000 and 2015. Additional data were obtained from a quantity surveying firm to validate the archival data on material prices, and to compare the firm’s robust database of project estimates and the corresponding outturn costs of specific building elements (detailed in the study). The goal of the analysis is to explore spontaneity and causal impact in the relationship between changes in prices of construction materials and project costs. Kolmogorov-Smirnov and Anderson-Darling tests were used to obtain the probability distributions of the causal relationships. Findings Findings show disproportionate positive correlations between changes in material prices and outturn costs in Nigeria. An important dimension to this, however, is that although fluctuations in material costs often trigger variations to project costs, outturn price only accounts for about one-third of actual cost variability. Recovery of costs, not least profit making, under these conditions is a complex process. Originality/value This paper concludes that dynamism in cost attributes is neither a deceit nor a delusion; understanding and tolerating them is not a systemic weakness, rather an essential key to project success and stakeholder satisfaction. Findings from the study also bring measured certainties to the transformation of variable costs into fixed price outcomes, an important consideration that will help contract estimators and project managers to understand the likelihood of fluctuation in material costs and how these might trigger variability in project costs.

First page: 372 Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose Building information modeling (BIM) has been proven to enable outstanding results in construction processes by enhancing knowledge sharing with regard to a building or facility throughout its life cycle from the conceptual design to facility management. The purpose of this paper is to investigate the extent to which the use of BIM has impacted the legal and contractual implications of the existing construction contracts for aligning the three sets of relevant development domains: BIM functionality, contract procurement methods, and BIM legal and contractual issues to enhance the efficient use of valuable resources. Design/methodology/approach This exploratory study was undertaken by analyzing the literature using a novel approach involving a matrix that juxtaposes BIM functionalities for each project life cycle with contract procurement methods. As part of the study, 28 interactions of BIM legal and contractual issues have been identified, as representing positive and negative interactions. Findings The interaction matrix framework that juxtaposes BIM functionalities and procurement methods highlights the theoretical and practical relationships identified between the methods. It also simultaneously recognizes the constructive and destructive interactions between these development domains by means of critically identifying the possible interactions of the legal and contractual aspects of both the BIM project procurement and the practical aspects of BIM project delivery. Originality/value The present study contributes to the existing literature by extensively identifying the probable interactions of contractual issues within BIM functionality with contract procurement methods throughout the life cycle of a building construction project.

First page: 386 Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose Public procurement capacity is composed of three facets: individual, organisational and an enabling national environment which encapsulates national legislation, policies and institutional arrangements that can facilitate or hamper the effectiveness of procurement. The purpose of this paper is to investigate the extent to which procurement capacity challenges in the national environment affect the effectiveness of infrastructure procurement by public agencies in Nigeria. Design/methodology/approach A total of 30 procurement capacity challenges drawn from literature were operationalized in a survey of infrastructure procurement personnel in different tiers of public agencies (i.e. local and state government) in order to ascertain the critical challenges affecting the effectiveness of infrastructure procurement. The survey yielded 288 responses, which were analysed using descriptive statistics, one-sample t-test and independent-samples t-test. Findings Challenges related to transparency, integrity and accountability are amongst the topmost challenges adversely affecting the effectiveness of public infrastructure procurement. There is limited difference in the extent to which the challenges affect the effectiveness of infrastructure procurement in different tiers of public agencies in Nigeria. Originality/value Whilst various procurement capacity challenges have been identified in the extent literature, this study has shown that an assessment of their effect on the effectiveness of infrastructure procurement could reveal valuable insights regarding the status of public infrastructure procurement within a country, particularly countries in Sub-Saharan Africa and other developing regions where there is acute infrastructure deficits. Such insights could inform appropriate infrastructure procurement reforms by policy makers, procurement entities and infrastructure funders.

First page: 403 Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose This paper focusses on external stakeholders’ perspective of stakeholder management in public–private partnerships (PPP) projects within the context of developing countries where public opposition to PPP projects is prevalent. The purpose of this paper is to identify the key enablers to PPP projects’ success from the perspective of external stakeholders. Design/methodology/approach Data were collected from two case studies via semi-structured interviews in two PPP project locations in Nigeria. In total, 14 external stakeholders comprising community leaders, trade unionists and human right activist participated in the research. Findings Five key enablers of external stakeholder management were identified. These are as follows: the choice of project location; transparency of the internal stakeholders; timing of stakeholder engagement; knowledge of PPP; and relationship with internal stakeholders. Originality/value External stakeholders’ perspective of stakeholder management in PPP projects within the context of developing countries new to PPP has been established. The practical implications of the five enablers can be used by policy makers and industry professionals to ensure effective stakeholder management of PPP projects.

First page: 415 Abstract: Built Environment Project and Asset Management, Ahead of Print. Purpose Knowledge-based economies are popular in the present world. Simultaneously, universities are becoming more responsible for leading economic development through research. As a key contributor to the national economy, it is vital for the construction industry to move beyond outdated practices, and hence, reviewing the role of academic research in empowering the construction industry with knowledge is essential. The purpose of this paper is to focus on how relevant theories conceptualise the expected role of academic research in the innovative development of an industry and the specific location in the Sri Lankan construction industry. Design/methodology/approach Following a comprehensive literature review, empirical data were collected from the Sri Lankan context with a mixed approach informed by a pragmatist philosophical stance. The perspective of academia and industry practitioners were deductively obtained through surveys and inductively explored through qualitative interviews. Findings This study provides evidence that academic research in Sri Lanka does not contribute effectively to innovative construction management. Due to the absence of industry-focussed knowledge dissemination strategies, the academic–industry relationships are mostly non-research based. The industry lacks in research-informed-decision making, leading to lesser innovations. Research limitations/implications The research conclusions are more applicable to the developing country construction industry contexts. Practical implications The research urges the need for improved academic–industry research collaborations and strategic knowledge dissemination movements. Originality/value The research confirms that academic research is a major integral part of the developing construction industry in a knowledge-based economy. In establishing the expected role of academic research, the research revealed the current practice to be under-located. Hence, the research prescribes the necessary actions; research collaborations in major and subsequent requirements.
