Building Information Modeling (BIM), also called n-D Modeling or Virtual Prototyping Technology, is a revolutionary development that is quickly reshaping the Architecture-Engineering-Construction (AEC) industry. BIM is both a technology and a process. The technology component of BIM helps project stakeholders to visualize what is to be built in a simulated environment to identify any potential design, construction or operational issues. The process component enables close collaboration and encourages integration of the roles of all stakeholders on a project. The paper presents an overview of BIM with focus on its core concepts, applications in the project life cycle and benefits for project stakeholders with the help of case studies. The paper also elaborates risks and barriers to BIM implementation and future trends.

Purpose – The objective of this paper is to present different perspectives on building “trust” among supply chain participants working on construction projects. Design/methodology/approach – A case study methodology was adopted; with five construction projects selected as five case studies for the trust in construction project on the basis a selection criteria devised for the research project. Over 40 interviews were conducted with participants operating at different levels in their respective organisations and at different point in the supply chain. Findings – The information provided by the multiple informants was, to a large extent, consistent with much of the academic literature relating to the importance of and barriers to trust. Specifically, the case studies highlighted: what people within the construction industry understand by trust, reliance, and honest professional relationship; the key factors that contribute towards building trust and factors that result into breakdown of trust; and organisational and project related factors that influence trust and relationships among people within the industry. Research limitations/implications – The findings from this study are limited due to: a small number of case studies undertaken, focused within the North West Region of England, and limited time and resources available. However, the ideas proposed for ways to develop trust in construction projects as seen from project findings have important implications for not only the clients but also for the main contractors and sub-contractors who need to pay greater attention to build trusting and long-term relationship as part of an integrated supply chain in order to deliver the continuous demand for services especially from public sector clients. Practical implications – If more businesses operating in the construction sector gave more thought to the importance of trust in construction projects then this could have a significant impact on contract design and over all procurement strategy. Specifically the repetitive work carried out by the local authorities in the UK, such as school building and maintenance, social housing stock improvement, etc., can be subcontracted to the contractors on a longer term basis resulting into long term supply chain relationship among organisations and cost savings. Originality/value – The research is among the first attempts in response to Latham report published in 1994, in order to explore the role of trust in construction projects, from the perspective of multiple stakeholders. The paper provides insights into the practical issues that prevent the widespread development of trust within the construction industry, which is a challenge that clearly warrants further attention from academics and practitioners.

The populations of major cities in Australia are increasing rapidly and facing an acute housing shortage. Traditional apartment procurement techniques involve lengthy lead times, and therefore, factory-based, or off site–constructed (OSC), multistory apartment buildings may offer the opportunity to help fulfill the need by significantly reducing build times and potentially offer good economic value. Other advantages of OSC may include superior quality, low weight ratios, economies of scale achieved through repetition of prefabricated units, use on infill sites, sustainable design standards, and better occupational health and safety. There are also positive labor and training implications, which may help to alleviate an industrywide shortage of skills through use of semiskilled labor. Previous uncertainties about the adoption of OSC because of the high capital costs and perception issues were generally based on precast concrete structures, which are a quite different building type in terms of flexi...

The construction industry is plagued by fragmentation of the functions carried out by the various disciplines involved in a project, particularly between the design and construction teams. Concurrent engineering (CE) is seen as a possible means of overcoming this problem. However, for the use of CE to produce the desired benefits, various issues have to be addressed, one of which is the use of appropriate organisational structures. To this effect, this paper explores organisational structures for the implementation of CE in the construction industry. It does so by first reviewing the main principles of, and issues concerning, CE and organisational structures, and by examining the structures which have been proposed for CE by researchers and those which have been used by manufacturing companies in their implementation of CE. By taking into account the peculiarities of the construction industry, this information is used, in conjunction with the results of case studies of companies within the industry, to suggest suitable types of corporate and project level organisational structures to support CE.

With the COVID-19 outbreak across the world, policymakers and authorities have realised that they cannot solve the emerging issues using conventional policies and practices. COVID-19 has severely affected many industries, including construction and demolition (C&D) waste management and C&D waste resource recovery sector. Extended Producer Responsibility (EPR) and schemes alike are policy instruments that prevent waste generation and promote a circular economy in the construction industry. These schemes are long adopted in various countries for different waste streams. EPR policy development and implementation, particularly for C&D waste, is still at an early stage in Australia. This study aims to review the Australian regulatory environment and practice to identify barriers and enablers towards successful policy development and implementation of C&D waste-related EPR. This study is based on secondary data that are publicly available. The document analysis was conducted to identify the level of regulatory and other stakeholders support in Australia. Following three rounds of examination of sources and applying multiple selection criteria, 59 different sources were reviewed in total. The results showed that there is widespread support among different stakeholders to develop EPR and expand the existing regulation to other materials. The barriers were cost and time implications for EPR policy establishment and enforcement, diversity of stakeholders involved, construction product lifecycle, responsibility of manufacturers, complexity in implantation of EPR regulations, modification inbuilt facilities and health and safety issues. Recommendations are made to alleviate these challenges. The outcome of this study could serve as a guideline for designing effective EPR policies.

Public private partnerships (PPPs) have gained widespread adoption as an innovative way of procuring public infrastructure projects over the last two decades. Risk identification, assessment, and allocation have received considerable attention from researchers due to the risk heavy nature of PPP projects. Adoption of PPPs has triggered a sudden increase in research interest in the area in recent years. This study attempts to provide an updated systematic review of literature related to risks in PPPs using a PRISMA flowchart. The results of the study offer some valuable insights into the future and current state of research. The study found that the focus of research on PPPs has shifted from an overall risk identification and assessment approach to individual risk analysis. Moreover, this research trend is on the rise in developing countries, and that quantitative methods for risk management in PPP research and qualitative methods in practice are preferred. In developed economies, due to negative public sentiments, transparency concerns, and arguments of value for money not being achieved, PPPs are becoming less popular. For these reasons a shift to availability-based payment mechanisms such as in Design-Build-Finance-Maintain (DBFM) from traditional revenue-based mechanisms as in Build-Operate-Transfer (BOT) has been observed. These shifts in research trends and practice offer researchers future opportunities to investigate these relatively newer approaches.
