The central goal of construction stakeholders is to successfully deliver projects to stated objective (s). However, for decades, construction projects have been plagued by perennial constraints of cost and time overruns, poor quality, and lack of sustainability. The objective of this paper is to identify and assess the constraints to construction project delivery, and to recommend solutions to enhance project performance. This paper adopted both quantitative and qualitative methods to establish the constraints in the Nigerian construction industry. A pilot survey and literature reviewed revealed a total of fifty (50) construction constraints, which were further classified into eight (8) major groups. Well-structured questionnaires were administered to construction stakeholders (client, consultant and contractor) in Abuja, the federal capital city of Nigeria. Relative Importance Index (RII) was used to analyze the data using Likert scale.  The results suggest that cost/time overrun related factors (inability to reduce project cost), Stakeholders interactive-related factors (inability to establish client value system), Client-related factors (Delay in interim payment and finance problem), and Labor/material-related factors (escalation of material prices and materials quality variability) are the most prevalent constraints in the Nigerian construction environment.  To mitigate the effects of these challenges, it is suggested that a formal innovative approach should be used by stakeholders to address the problems of poor communication, high project cost, and delay. Clients should also take measures to provide adequate funding and should promptly honor interim certificates.

Purpose The non-achievement of projects of best value remains a perennial problem within the construction industry. This paper aims to identify the latent shortcomings affecting the achievement of value for money (VfM) within the Ghanaian construction industry. Design/methodology/approach From a comprehensive literature review and pilot survey, 18 variables responsible for the non-achievement of VfM were identified. Through purposive and snowballing sampling techniques, a questionnaire was administered to the target professionals. Factor analysis was used to establish the latent shortcomings underlying the same dimensions of VfM achievement in the Ghanaian construction industry. Findings A total of six components were identified and explained as external factors; institutional culture and policy constraints; technical and decision-making factors; human-related factors and accountability and transparency constraints. The relative importance index was used in analysing the strategies to addressing the shortcomings. Social implications The prevalent situation of poorly delivered projects and the continuous campaign for VfM necessitated the need for a study into explaining the latent shortcomings in achieving VfM within the Ghanaian construction industry. It is recommended that governments give VfM in public projects serious attention. This would help to reduce the overall cost of construction projects without compromising quality. When VfM is taken seriously, governments can save more money and undertake more projects as well as gain public acceptance in terms of transparency and accountability. Originality/value This study has set the pace for further research in the VfM analysis by identifying the latent shortcoming, which other developing countries can emulate.

Negative Perceptions

The fourth industrial revolution (4iR) technologies offer an opportunity for the construction industry to improve health and safety (H&S) compliance. Therefore, implementing the technologies is of top priority to improve the endless H&S incidents in construction projects, which lead to poor quality of work, late project delivery, and increased labour injury claims. Central to improving the nature of work and other industrial processes, the 4iR technologies have emerged. Concurrent with this trend is the importance of 4iR technologies in enhancing health and safety performance on construction sites. However, the implementation of 4iR technologies in the construction industry is faced with various challenges. Therefore, this paper reports on a study aimed at examining the challenges associated with implementing 4iR technologies in the construction sector in South Africa towards effective management of H&S. The study followed a systematic literature review, data collection using a questionnaire survey and thereafter, descriptive, and inferential analyses were conducted. The findings revealed that the implementation of 4iR technologies is challenged by a lack of adequate relevant skills, the unavailability of training capacities, expensive technologies, and negative perceptions such as fear of job loss by industry professionals. The findings are essential for the advancement of H&S research and implementation. In addition, the findings are important to industry decision-makers in order to elevate their awareness and promote the use of 4iR technologies to manage construction activities. The study implications include the need for the construction industry to collaborate with higher education institutions to conduct research and include 4iR in the curriculum.

A meta-synthesis approach was used to identify, synthesize, and categorize appropriately factors in the literature that contribute to design documentation quality. The categories include factors on quality attributes, quality indicators, and quality-influencing factors. Findings indicate that the quality of design documentation in practice is unsatisfactory, therefore, there is a need for collaboration between the owner, designers, and end-users to improve design documentation quality. The results offer pragmatic data on design documentation quality in the construction industry between the years 1992 and 2019. However, further research on the significant impacts of poor-quality design documentation on construction projects is recommended.

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.

Construction practitioners recognise that rework is undesirable due to the detrimental effects. While rework literature has examined rework causation factors in construction projects, the problem continues to plague the industry resulting in poor delivery performance. To better understand this phenomenon and given the scarcity of Malaysian-based rework study, a questionnaire survey involving 130 Malaysian construction practitioners (consultants, contractors and clients) were undertaken to obtain feedback about nature, implications, causes and solutions for rework. Data were analysed using descriptive statistical techniques to prioritise the variables studied. From the analyses, rework is a causal factor for delays and cost overruns, higher wastage and productivity inhibitor. The findings revealed the leading causes of rework are poor quality management, improper planning, lack of communication, design changes and poor subcontractor management. Some practical rework minimisation approaches are also suggested to better manage and prevent rework towards enhanced project performance.

Questionnaire Surveys

In recent decades, the construction industry has been widely criticized for its lack of efficiency and productivity, and it has been shown that the Malaysian construction industry records poor quality on its projects. To overcome this issue, the Technical Committee on Quality Assessment in Construction with the support of the Construction Industry Development Board (CIDB) has introduced Quality Assessment System in Construction (QLASSIC). QLASSIC is a scoring system that is used to assess and evaluate the performance of construction buildings. It is based on the Construction Industry Standard (CIS 7:2006). Unfortunately, this assessment system had poor implementation since its introduction in November 2006. QLASSIC was not extensively implemented and was taken lightly by the contractors and developers in Malaysia. There are still a huge number of contractors that are not aware of QLASSIC even the big construction companies. Thus, this research is aimed at investigating the contractor’s perspective towards the implementation of QLASSIC in the construction industry in Malaysia. Three objectives are developed to achieve the aim: (1) identification of the needs to implement QLASSIC; (2) investigation of issues and challenges to implement QLASSIC and (3) recommendation of strategies to implement QLASSIC. Structured questionnaire surveys were distributed to the G7 and G6 contractors in the Klang Valley area; which may have or may not have experience in implementing QLASSIC in their projects. The result revealed that majority of the respondents were aware and understand the needs of QLASSIC implementation, but there were still few who were unfamiliar with the QLASSIC. The current level of implementation of QLASSIC in Malaysia is still not satisfactory due to several issues and challenges acting as barriers to its implementation. Therefore, the initiatives from the government are important to promote QLASSIC implementation in the construction industry. By doing this, the contractors would be aware of the implementation of QLASSIC in the construction industry. The significance of this research is that it will assist contractors and other construction players in comprehending the implications and importance of QLASSIC implementation.

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.

Poor productivity of construction craftsmen is one of the causes of cost and time overruns in construction projects. Successful delivery of construction of projects within the measurable tenets is driven by effective site supervision. Nevertheless, the inability of many supervisors to organize, communicate with workers, and direct activities sufficiently is primarily connected to the quality of the construction. Hence, this study examined how enhanced supervision styles can lead to the improvement of craftsmen performance in Anambra State, Nigeria. Being a survey research, the study employed the use of review of related literature and structured questionnaire. Accordingly, a total one hundred (100) questionnaires administered and seventy-five (75) were retrieved. This corresponds to a response rate of 75%. Data garnered were analysed and presented using relative importance index, mean scores and frequency tables. The study found out that listening to subordinates or supervisees was the most important supervision styles for improved building craftsmen performance in the study area. Therefore, the study concluded by recommending team work and effective communication channels should be adopted for improving building craftsmen performance as regards project delivery.

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.

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
