Projects supply chain is overwhelmed with unethical practices. Managing construction projects supply chain, which is traditionally void of transparency, has led to issues of corruption, vested interest, clientelism, ghosting, bid rigging and poor professional ethical standards. The centralized nature of data management in the construction industry is characterized by the lack of visibility and transparency of details and this lack of visibility is a major cause of inefficiency in construction project delivery. The objective of the paper is to assess the indicators for adaptability of projects supply chain using blockchain technology. The article adopts a bibliometrix strategy to extract qualitative data from existing peer-reviewed articles. The research design is a combination of different approaches, including bibliometric and visualization, bibliometric and content analysis, as well as bibliometric, visualization and content analysis. Data was obtained from articles indexed on SCOPUS and Web of Science. R-studio was used for data analysis, while VosViewer was used for visualization. The paper is a part of an on-going research. The research is exploratory and adopts a pragmatist approach. The research is expected to develop a framework that will introduce transparency and provenance in projects supply chain using blockchain technology. Findings from this review show that there are indicators for adaptability of construction projects supply chain using blockchain.

The Government

Economic transformation and the provision of basic infrastructure to engender growth and development in any nation is vested in the construction industry hence the massive investment of the government in this sector. However, the expected gains of the construction industry have been eroded by the failure of many construction projects due to unethical professional practices on the part of the construction professionals. This study analyzed the causes and effects of unethical practices on the industry and project delivery with measures to combat the unethical practices among the stakeholders. The study adopted the survey design and a stratified random sampling technique was used to select 140 respondents. A structured questionnaire was designed and administered to construction professionals (Architects, Quantity Surveyors, Builders and Engineers). The relative importance index tool was used to analyse the severity of the factors identified. Findings revealed the absence of punishment for unethical practices (0.94), collusion between officials, consultants and contractors (0.91), availability of loopholes in project monitoring (0.89), weak law enforcement institution (0.87) and greed for money (0.83) among others as major causes of unethical professional practices which have serious effects on the construction industry. The result also revealed poor workmanship and substandard project delivery (0.88), high cost of construction (0.86), the collapse of structures/buildings (0.82), inflated contract sums (0.81), high maintenance cost (0.79), time and cost overrun (0.76) as the extremely severe effects of unethical practices in the industry. Prosecution and punishment of offenders (0.98), the whilstle blower protection policies and rewards (0.84), strengthening of institutionand anticorruption agencies (0.78), award of contracts on merit (0.75) and civil society participation and oversight (0.68) were identified as highly effective measures to curtail unethical professional practices. The study recommends that the government being a major actor should abide by the due process of contract award and letting, using Public Procurement Act (PPA) guidelines in executing all its construction projects. The professionals, contractors and clients’ representatives should also exhibit high professional excellence through adherence to professional ethics and codes of conduct.

Interview Survey

Despite its obvious theoretical benefits, there has been some reservations regarding the practical implementation of Value Management (VM) for construction projects. In particular, these concerns the extra time and costs involved in conducting VM in relation to the actual benefits gained as a consequence of its use. This paper provides the result of an interview survey of the experiences and observations of 17 professionals working in the property and construction industry to establish the extent to which this is an issue. The main conclusion is that the process is working well, with VM being popular among those with experience in its use - which has been extended into the area of consultant selection. However, in contrast with the prescriptive literature, much of the participants' experiences appear to be more concerned with VM's contribution to the identification and management of the risks involved in project delivery than the straight value-for-money aspects. This may be due to the higher levels of uncertainty involved in construction work than in VM's original use in construction.

This paper presents findings of an investigation into benefits of using Building Information Modelling (BIM) in construction projects. The research methodology includes a review of BIM development and achievement in construction industry, questionnaire survey, interview, and content analysis of secondary data. Data was collected and analyzed to identify the various benefits reflected from BIM implementation in addressing common problems experienced by the construction industry. The review and survey results indicate that a high frequency of occurrence of time and cost overruns occur in construction projects. Contributing factors were mainly rework, poor planning, documents delivery and approval, constructability issues, resources and weather condition. While some of the factors were unpreventable, BIM could be used as a tool to eliminate problems causing time and cost overruns. Various project benefits have been reflected through the content analysis of project case studies. It was found that time was the most positively influenced by the use of BIM followed by coordination, procurement, communication, cost and change of scope of the project, and lastly, risk.

Ranking Analysis

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.

Carbon estimating plays a vital role in the construction industry. The current focus on introducing zero-carbon construction projects reduces operational carbon, at the expense of Embodied Carbon (EC). However, it is important to reduce overall net carbon emissions. There are various methods to estimate carbon, but the accuracy of these estimates is questionable. This paper reviews a novel methodology, the Supply Chain based Embodied carbon Estimating Method (SCEEM), which was introduced recently to accurately estimate EC in construction supply chains. SCEEM is compared against existing EC estimating methods (Blackbook and eToolLCD) using a case study approach. It is also supplemented with a comprehensive literature review of existing EC methods. The EC values calculated using Blackbook and eToolLCD were mostly higher than SCEEM. Since SCEEM uses actual site data and considers first principles-based value addition method to estimate EC, it is considered accurate. The cross-case analysis revealed that SCEEM provided consistent results. Hence, SCEEM is recommended to accurately estimate EC of any type of project.

The United Arab Emirates construction industry is beset with negative project performance outputs, such as defects, low productivity, delay in completion, and higher costs. Most critical among the recorded reasons for having these undesirable outputs is the engagement of unskilled craft workers. However, the demand for construction projects in the UAE is continually increasing, especially after Dubai won hosting of Expo 2020, as this consequently translates to increased demand for skilled construction craft workers, if optimal project delivery performance must be achieved. Therefore, subject matters related to skillfulness and productivity of construction craft workers become research windows for academic scholars and industry investigators in the UAE built environment. The main purpose of this study is to explicate the reasons behind employment of unskilled craft workers in the construction projects from the management level perspective. To meet this purpose, the authors conducted in-depth interview with construction project managers. The results show number of reasons why unskilled craft workers are been hired and the effect of specialized certificates on hiring the craft workers

Illegal Dumping

This nowadays an increasing number of construction projects in Malaysia have contributed to the production of construction waste which has had a negative impact on the environment, especially through illegal dumping. The increasing number of illegal dumping activities is a sign that construction waste management needs to be examined. To date, a comprehensive criterion for construction waste management, in developing countries is still not clearly defined. Therefore, the objectives of this paper are to investigate current illegal dumping activities, and identify the challenges towards reducing illegal dumping activities in the Malaysian construction industry. Hence, this research conducted interviews with 20 expert stakeholders related to construction waste management in order to scrutinise illegal dumping activities in Malaysia. The data from these semi-structured interviews were analysed by content analysis. The findings are used to determine the current challenges for reducing illegal dumping activities in the Malaysian construction industry. The elements in the current findings are potentially to improve construction waste management in order to archive the proper construction waste management. Finally, this findings will help to identify strategies to reduce illegal dumping activities and to enhance challenges towards reducing illegal dumping activities in the Malaysian construction industry.
