Knowledge is the resource that contributes the most to an organisation’s competitiveness. Construction projects usually introduce project teams from different disciplines. Hence, knowledge in projects is complex and difficult to manage. To efficiently manage knowledge in projects, various strategies and tools have been applied over the years to support knowledge management (KM). Building information modelling (BIM) is a technology that has recently gained a lot of attention in the construction industry. The main feature of BIM is object-oriented and parametric modelling with the functions of dynamic visualisation, life cycle simulation, early analysis, coordination and collaborative working. Many studies have explored the functions of BIM mainly at the information level. However, only a few studies have considered the management of knowledge in a BIM environment. To fill this knowledge gap, this study explored the potential and expectation of a BIM-based system for early collaboration among contractor, facility management (FM) and design teams in the design stage. This study chose semi-structured interview as the main method to collect qualitative information. A total of 30 experts working in the construction industry were interviewed. On the basis of the analysis results of the collected information, a discussion was presented on how BIM can facilitate KM activities and relieve KM challenges. Therefore, the discussion focused on the requirements and expectations of the integrated KM system in a BIM environment that can facilitate the early involvement of construction contractors and the FM team into the design stage. This study also provides a new research direction for the transformation of research focus from BIM to building knowledge modelling. This paper is the revised version of the paper that has been published in the proceedings of the Creative Construction Conference 2018 (Wang et al., 2018).

Financial Losses

Construction industry is an important industry and remains so with the continuation of the development process especially in the developing countries. On the other it is very risk and hazard. As industry when compared to other industries financial losses and bodily injury and death, and resulting human, social impacts are more in the case of construction.  Mishaps also contain significant costs that are not insurable. Financial deliberations contains direct costs like medical reimbursement and  hidden costs includes loss of competence by breaking up crew, cost to train fresh or changed employee, damage to equipment and tools, cost experienced by delays. Many researchers have been suggested risk management techniques to minimize the losses in the industry and very few companies may be implemented the suggestions.  The goal of this study is to recognize and rank risks in construction projects. This study proposes the hierarchical dependencies between the criteria. The variations and factors have been investigated via questionnaire and is an element of an on-going research into the application of risk management in major projects. To know the performance and applicable of proposed model set of data collected from different industries by using the informal approaches such as intuition and experiences the study is conducted to prioritize and manage risks.

Sustainable procurement is an emerging theme in the construction industry across the globe. However, organizations in the construction industry often encounter impediments in improving environmental performance in construction projects, especially in procurement. Besides its other facets, procurement of construction equipment is inherited to be capital-intensive and vital for managing environmental concerns associated with built environment projects. In this regard, selection criteria in such procurement processes are generally supportive of considering cost and engineering specifications as key parameters. However, sustainability apprehensions in today’s Malaysian construction industry have mounted pressure on industry professionals to rethink their equipment acquisition strategies. The notion of green or sustainable procurement is still infancy for the Malaysian construction industry and facing challenges for embedding it in the current procurement practices. This research aims to address these apprehensions by considering six main criteria, namely, life cycle cost (LCC), performance (P), system capability (SC), operational convenience (OC), environmental impact (EI), and social benefits (SBs), and their 38 subcriteria towards procurement of sustainable construction equipment. A multicriteria-based equipment selection framework on the triple bottom line of sustainability in the context of the Malaysian construction industry has been developed and tested. The application of analytical hierarchy process (AHP) established the sustainable procurement index with a consistent sensitivity analysis results. As such, the proposed procurement index shall help decision-makers in the process of the acquisition of sustainable construction equipment in Malaysia.

Prefabrication has been widely adopted in the construction projects in recent years. It has also been advocated as a greener and more sustainable approach of project delivery. However, with a wealth of evidence supporting other reasons as the drivers of using prefabrication, it is questionable whether the real goal of prefabrication is to achieve sustainable construction. This study aims to investigate the roles of prefabrication in fostering sustainable construction. The effectiveness of prefabrication on fostering sustainable construction was evaluated on the five aspects enlisted by the UK’s Green Construction Board: Waste, Water, Carbon, Materials, and Biodiversity. An industry survey was conducted in Melbourne, Australia for data collection. 200 questionnaires were sent via email or post to a variety of fields within the construction industry. Entropy ranking analysis was adopted to analyze the effectiveness of using prefabrication in construction. The results suggest that prefabrication is effective in reducing construction waste and sourcing energy efficient materials. However, the utilization of prefabrication was found unsuccessful in reducing carbon emissions during the construction process. It is suggested that proactive actions should be taken at the design stage to unleash the potential of prefabrication in construction.

PurposeThough the Public Procurement Act of Ghana makes room for specific socio-economic policies (environmental, social, economic and other policies which are intended to promote social and economic impact), there is no explicit definition and provision for social value as an evaluation criterion, culminating in the absence of a definition in the Act. This paper elicits the conception and understanding of social value from stakeholders in the Ghanaian construction industry.Design/methodology/approachThe study adopted a qualitative method that relied on a semi-structured interview of 30 participants purposively drawn from Western, Western North and Central regions of Ghana. An inductive thematic analysis approach, which involved identifying repetitions, exploring similarities and differences, noting linguistic connectors, and a framework were employed to analyse the data.FindingsThe study established no single definition or explanation for social value in the construction industry in Ghana. However, it was revealed from the study that the concept of social value could be defined from the functional perspective of the definer, particularly from the perspective of a Procurement Officer, Works Engineer, and a Quantity Surveyor. A new insight from the study that differs from the body of literature is that participants equated benefits derived from physically constructed projects as social value.Social implicationsThe study has implication for public administration and practice regarding the decision-making process in the construction industry in Ghana. It provides a vital awakening on social value as a criterion in evaluating construction works procurement in Ghana. The ability of participants to equate the benefits derived from executed construction projects as social value creates a new perspective on understanding the meaning of social value in the procurement of works construction.Originality/valueThe study contributes to the state-of-the-art and ongoing discourse on the concept of social value globally. The findings create an important catalyst for social value research in the Ghanaian construction industry.

Proposed Model

Schedule delays frequently occur in construction projects. The first step in resolving delay problems is to identify the main causes of delay. Previous studies identifying significant causes of delay have not examined how different causes work together to influence project schedule delays. Structural equation modeling (SEM) of causes of delay in construction has been developed for describing and quantifying the influence of different causes. Although this empirical study is based on a survey in Taiwan’s construction environment, the proposed model is applicable to construction industries in other countries. The analytical results clearly show the correlations among key causes of delay, which is the basis for resolving future schedule delays. This study proved that SEM is capable of quantifying the comprehensive relationships among investigated factors. Additionally, SEM has a high potential to resolve experience-oriented problems in the construction industry.
