  • Concentration Analysis of New Private Residential Units Market in Hong
           Kong

    • Authors: Sai On Cheung, Brigitta Levina, Yuhan Niu
      Pages: 1 - 23
      Abstract: The new residential property price in Hong Kong has rocketed in the last decade and has ranked within the top three metropolitan cities in the world. Housing is a necessity for most people, high residential property price has its social ramification. The rocketing price seems not solely the result of the market. As such, this raised the issue of competition in this market. This study employs Concentration Ratio and Hirfindahl-Hirschman index to evaluate the market concentration of the New Private Resident Units Market in Hong Kong. Using the best information available in the public domains and applying universal thresholds, the New Private Resident Units Market in Hong Kong is considered moderately concentrated. It is noted that the big five listed developers in Hong Kong are collectively holding a dominant position of the potential supply. Moreover, the top three have comparable market shares thus suggesting no monopoly exists. It is also found that the substantial land banks held by the five big listed developers, amount to 60% of that owned by the Government. These developers will therefore retain their dominant market power in the future. Further study is recommended to examine whether the big developers have abused their market power.

  • Volume Home Building: The Provision of Sustainability Information for New
           Homebuyers

    • Authors: Georgia Warren-Myers, Erryn McRae
      Pages: 24 - 40
      Abstract: The new residential housing sector is producing approximately 200,000 homes a year that could benefit from methods to increase sustainability and energy efficiency. Currently, there is limited implementation of sustainability measures beyond mandatory minimum requirements in Australia. New homebuyers are often the scapegoats for the poor sustainability adoption due to their perceived lack of interest and willingness to pay. However, their knowledge and engagement in sustainability is likely to be strongly guided by information provided by the volume builders. This paper investigates the sustainability information that homebuyers are provided by builders, as communicated through their websites. Web searching as an important means of information gathering in the preliminary stages of the process for new homebuyers. This paper reports on the analysis of Australia’s Home Industry Association’s top 100 volume builders’ websites and their provision of sustainability information. The results suggest the lack of sustainability-related information provided by builders is contributing to disengagement by consumers in the sustainability features available in new homes.

  • Towards a Coherent Theory of Project Alliancing: Discovering the
           System’s Complex Mechanisms Yielding Value for Money

    • Authors: Pertti Lahdenperä
      Pages: 41 - 61
      Abstract: Alliancing is a relatively new construction project delivery method receiving increasing interest globally while also eliciting many questions about its effectiveness. That is why its operating logic should be clarified beyond the currently existing general views. Correspondingly, this paper aims to define the means and mechanisms which influence the capacity of alliancing to produce value for money. The work establishes the interlaced impact chains between formal basic solutions of alliancing and the key result areas defining the value-for-money ratio. This is made by focussing on a single alliance project and its procedural solutions and experiences. The case project of the study was an urban road tunnel under a city structure and the impact chains were explored by interviewing all eight members of the alliance leadership team covering all contracting parties. The two-stage personal interviews were conducted in accordance with the systematic modelling procedure resulting in eight cognitive maps which were then combined into a group map. The resulting model included around one hundred interlinked concepts initially, but was streamlined for the paper. Accordingly, alliancing offers a concrete framework which gives better than normal chances of success in the case of complex, challenging projects fraught with much uncertainty. Many diverse basic alliance solutions/features contribute to success, while each feature also seems to strengthen the impact of the others. This suggests that, at its best, pure project alliance is not only a coherent but also a holistic solution to challenging projects.

  • Determining Success Criteria and Success Factors for International
           Construction Projects for Malaysian Contractors

    • Authors: Ali Mohammed Alashwal, Nurfarhana Farza Fareed, Karam Mustafa Al-obaidi
      Pages: 62 - 80
      Abstract: The success of international construction projects is fraught with various challenges such as competitiveness, lack of resources, versatile global economy, and specific conditions in the host country. Malaysian contractors have been venturing into global construction market since early 1980s. However, their venturing was not successful all the time. The number of international projects awarded to Malaysian contractors has reduced drastically during the past decade. Taking advantage of this experience, this paper aims to identify the success criteria and success factors of international construction projects. The data was collected from 120 respondents using a questionnaire survey and analysed using principal component analysis and regression analysis. The results revealed three principal criteria of project success namely, Management Success, Functional Success, and Organisation Success. The main components of success factors include Team Power and Skills, Resource Availability, External Environment, Organisation Capability, Project Support, and Project Organisation. Further analysis emphasized the importance of strong financing capacity of contractors, project social environment, and competence of the project manager in achieving project success. The results of this paper can serve as a guideline for contractors and project managers to achieve success in this context. Future studies may provide in-depth analysis of success criteria and success factors specific for construction project type and host-country location.

  • Critical Evaluation of Environmental, Social and Governance Disclosures of
           Malaysian Property and Construction Companies

    • Authors: Renard Yung Jhien Siew
      Pages: 81 - 91
      Abstract: There is an increasing demand from stakeholders for higher transparency on environmental, social and governance (ESG) disclosures. Yet not much is known about the state of sustainability reporting in Malaysia especially in the property and construction industry. This paper aims to fill this gap accordingly. Content analysis of corporate websites, sustainability and annual reports was adopted as the main methodology in this study. Findings show that corporate governance indicators are most reported by Malaysian construction companies compared to other environmental or social indicators. It was also found that details on actual health and safety performance of these companies and the initiatives implemented were largely absent from their reporting. Given the increasing number of rating tools in the capital markets which serve to rank and file companies based on their sustainability disclosures and performance such as the Dow Jones Sustainability Index (DJSI) and FTSE4Good Index, it is questionable as to how reliable this can be done for the Malaysian property and construction market. The paper will be useful to construction management practitioners and ESG analysts with a focus on Asian markets.

  • Reliance on and Reliability of the Engineer’s Estimate in Heavy
           Civil Projects

    • Authors: George Okere
      Pages: 92 - 114
      Abstract: To the contractor, the engineer’s estimate is the target number to aim for, and the basis for a contractor to evaluate the accuracy of their estimate. To the owner, the engineer’s estimate is the basis for funding, evaluation of bids, and for predicting project costs. As such the engineer’s estimate is the benchmark. This research sought to investigate the reliance on, and the reliability of the engineer’s estimate in heavy civil cost estimate. The research objective was to characterize the engineer’s estimate and allow owners and contractors re-evaluate or affirm their reliance on the engineer’s estimate. A literature review was conducted to understand the reliance on the engineer’s estimate, and secondary data from Washington State Department of Transportation was used to investigate the reliability of the engineer’s estimate. The findings show the need for practitioners to re-evaluate their reliance on the engineer’s estimate. The empirical data showed that, within various contexts, the engineer’s estimate fell outside the expected accuracy range of the low bids or the cost to complete projects. The study recommends direct tracking of costs by project owners while projects are under construction, the use of a second estimate to improve the accuracy of their estimates, and use of the cost estimating practices found in highly reputable construction companies.

  • Lean Construction Implementation in the Saudi Arabian Construction
           Industry

    • Authors: Jamil Ghazi Sarhan, Bo Xia, Sabrina Fawzia, Azharul Karim
      Pages: 46 - 69
      Abstract: The Kingdom of Saudi Arabia (KSA) has witnessed a huge increase in construction during the last two decades. However, many projects experienced time delays, cost overruns and the generation of massive amounts of waste. To address these challenges, lean construction has been introduced into the Saudi construction industry; however, it is still in its infancy. This study therefore investigates the current state of lean construction implementation in the construction industry in the KSA. The objectives are to identify: the types of construction waste, level of use of tools that support the implementation of lean construction, stages of application of lean methods, and the benefits of lean construction. To achieve these objectives, a structured questionnaire survey of 282 construction professionals was carried out. After the analysis of the collected data using mean score and Anova test, the following conclusions were made.  In the construction industry in the KSA, waiting is the most common type of waste, while Computer Aided Design (CAD) is the conventional tool supporting the implementation of lean construction. Furthermore, the data suggests that lean construction is most commonly used in the construction stage of projects while customer satisfaction is the main benefit derived from lean construction practices. This study concludes that the level of implementation of lean construction in the KSA construction industry is increasing. The results will help benchmark the current state of lean construction implementation, which will enable the construction industry to identify strategies to implement lean construction in Saudi Arabia in accordance with their needs and project goals, to achieve better productivity.

  • Factors Influencing the Private Involvement in Urban Rail Public-Private
           Partnership Projects in China

    • Authors: Yongjian Ke, Weiya Hao, Huiping Ding, Yingying Wang
      Pages: 90 - 106
      Abstract: Private investors have been encouraged to participate in the development and operation of urban rail projects in China through Public-Private Partnerships (PPPs), given the fact that subnational governments are suffering from urgent development demands and severe fiscal pressure. However, there is no formal assessment to determine the private involvement in a PPP project. This problem is particularly critical in the sector of urban rail, in which the huge investment cannot rely on the private sector alone. This study hence aimed to uncover and identify the influencing factors. Multiple research methods, including content analysis, case study and focus group discussion were adopted to achieve the research purpose. Seven types of influencing factors were identified, including project financial model, government fiscal commitment, risk allocation, public accountability, efficiency considerations, policy and regulations, and organisational marketing strategies. The findings add to the current knowledge base by uncovering the drivers behind private involvement in a PPP project. They are also beneficial for industry practitioners as a basis/checklist to determine the private involvement.

  • Insights into Architects’ Future Roles in Off-Site Construction

    • Authors: Jianing Luo, Hong Zhang, Willy Sher
      Pages: 107 - 120
      Abstract: Today’s construction industry is overflowing with new ideas about its future. Off-Site Manufacture and Construction (OSCM) is at the heart of the modern construction industry. Much has been written about the state and context of OSCM in different countries regarding its perceived benefits and barriers to implementation. Off-site production (OSP) plays an important role in improving fragmented construction processes. Although most OSP research targets the attitudes and practices of OSP adoption, there is limited understanding of the philosophical issues underpinning OSP-related architecture. The roles of the architects’ personal philosophies are neglected and this hampers their implementation of OSCM (which has had a largely technical focus). This paper explores the traditional thinking patterns of architects in China and predicts possible future roles for them. It then conceptualizes an “architectural work” mode and a “building product” mode of design and construction and identifies the shortcomings of architects in an OSCM environment. The arguments made are based on practitioners’ perceptions and the first author’s practical experiences of leading several real-life projects in recent years. The findings reveal the implications and significance of the transformation from an “architectural work” mode to a “building product” mode. We foresee a study approach that focuses on the order and rules for OSCM, resulting in architects’ existing mindsets being changed to thinking patterns and design methodologies better suited to OSCM.

  • Where the Gaps Lie: Ten Years of Research into Collaboration on
           BIM-Enabled Construction Projects

    • Authors: Mehran Oraee, M.Reza Hosseini, Saeed Banihashemi Namini, Christoph Merschbrock
      Pages: 121 - 139
      Abstract: A BIM-enabled Construction Project (BIMCP) refers to a project involving relevant BIM tools to generate, exchange and manage project data between project participants. Success in delivering BIMCPs largely relies on how effective project members collaborate. As a result, collaboration on BIMCP has become a growing field of research while a review of studies on collaboration on BIMCPs is still missing. To address this gap, this paper presents the findings of a systematic review on studies devoted to collaboration on BIMCPs over the past 10 years (2006-2016). To this end, 208 studies published in 12 ICT-oriented journals in the construction context are thoroughly reviewed. The findings bring to light that studies on collaboration on BIMCPs are sporadic, isolated and focus on narrowed, limited and disjointed areas associated with collaboration. The study contributes to the field through highlighting the gaps of the existing literature on the topic. This provides a stepping stone to direct future inquiries that target collaboration on BIMCPs.
