The construction industry in Nigeria faces many problems, including the delay due to variations in project execution. This delay has been studied as a major setback in the Nigerian construction industry. In Nigeria, the construction industry's performance in terms of time has been observed to be poor. The objective of this study is to examine the variation of the construction project in order to determine the effect on the delivery of the project. The maximum performance of the project would be reached if the work always goes efficiently on time with the budget. The result of the variation is delay, cost overruns, quality defects and other negative impacts. The causes of variation were identified by a questionnaire survey for two higher education institutions. The results of the study identified the five main factors, including change of plan or scope, defective labour, customers' financial problems, unavailability of skills and desired profitability of the entrepreneur. In general, the study shows agreement among clients, consultants and contractors regarding the classification of the 20 factors that cause the variation. The results also reveal that factors related to clients are the main causes of variation, followed by factors related to contractors. An understanding of the causes and effects of the variation would be helpful in training professionals to assess the variation. In addition, the study would also help professionals take proactive measures to reduce the gaps on construction projects.

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.

PurposeIt is well recognized that the construction industry is characterised by inefficient and ineffective service delivery due to various causative factors. Thus this study aims to examine the influential factors affecting public construction project performance in Ethiopia to improve the industry's service delivery.Design/methodology/approachFrom the extensive literature reviewed, 58 potential factors affecting construction project performance have been compiled. Based on the evidence accumulated, the conceptual model of this paper has been developed. By using survey questionnaires, valuable data were collected from the construction industry professionals in Ethiopia; analysed and interpreted with the use of both SPSS and AMOS software.FindingsIt is concluded that failure factors related to the “performance” of the contractor, the “capability” of the owner, the “project design-procurement process,” and project contract management can significantly contribute to the poor performance of public construction projects in Ethiopia. Ten key factors include inadequate contractor capacity, weak project site management and supervision, weak project management skills and capabilities of the owner, additional work orders, delayed payment, lack of comprehensive project plans between parties and incomplete project design, rising material prices, ineffective project schedules, and cost management, rising market prices and devaluation of the currency.Research limitations/implicationsThe scope of this study confined to public projects in Ethiopia. It suggests that further research needs to consider public and private construction from a comprehensive perspective in the developing countries.Practical implicationsIt provides practitioners with information and guidance on the factors that affect the performance of construction projects.Originality/valueIt provides inclusive evidence related to many factors that affect the performance of public construction projects.

The Impact

Purpose The coronavirus disease 2019 (COVID-19) pandemic has affected the global economy and, thus, the global construction industry. This paper aims to study the impact of COVID-19 on construction project performance in the United Arab Emirates (UAE). Design/methodology/approach This study adopted a qualitative and exploratory approach to investigate the impact of COVID-19 and its policies on project performance in the UAE construction industry in critical areas of the project management body of knowledge (e.g. schedule, cost, resources and contracts). Semi-structured interview questions were asked from ten construction professional to obtain valuable insights into the pandemic’s effects on the UAE construction industry and the effectiveness of policies implemented to rectify the damage and identify the industry’s new normal. Findings The findings indicate that the construction industry faced several challenges such as schedule delays, disrupted cashflows, delayed permits, approvals and inspections, travel restrictions, serious health and safety concerns, material and equipment shortages, among others which hindered the timely delivery of construction projects. It also indicates that efforts made by the government institutions and the construction industry of the UAE such as economic support programs, digitization of processes, fee and fine waivers, health facilities, among other statutory relaxations proved effective in supporting the construction industry against the adverse effects of the pandemic. Research limitations/implications The research findings are limited to the literature review and ten semi-structured interviews seeking an expert’s opinion from industry professionals working in the UAE construction industry. The research team did not get access to project documents, contracts and project progress reports which may be required to validate the interview findings, and to perform an in-depth analysis quantifying the impact of COVID 19 on construction projects performance, which is a limitation of this research. Practical implications The implication is that, owing to the imposed lockdowns and strict precautionary measures to curb the rapid spread of the pandemic, smooth execution of the construction project across the country was affected. The government institutions and stakeholders of the construction projects introduced and implemented various techniques and solutions which effectively handled the implications of the COVID-19 pandemic on the construction industry of the UAE. Originality/value This study has identified the challenges faced by the construction industry of the UAE in the context of the management of project schedule, project cost, construction contracts, health and safety of construction employees and other related aspects of the construction projects. This study also identified the techniques and solutions adopted by various public and private institutions of the country and their implications on construction projects. Therefore, this study provides guidelines for policymakers and future research studies alike.

Labor Issues

The construction industry in the United Arab Emirates (UAE) is faced with negative project performance, including low productivity, higher costs, delays in project completion, and defects during construction. One of the main reasons for these issues is the engagement of unskilled craft workers. Despite these labor issues, demand for construction projects in the UAE has been explosively increasing, in part due to Dubai winning the hosting of Expo 2020, which has given rise to an unprecedented demand for skilled construction craft workers. This study aimed to investigate the views and experiences of construction project managers regarding the reasons and challenges associated with the hiring of skilled craft workers in the construction labor market of the UAE. To fulfill the study purpose, the authors conducted structured open-ended interviews with UAE construction project managers. The results revealed several reasons for hiring craft workers despite a clear lack of qualifications and suggest some potential solutions.

Design Changes

Design changes in construction projects are always going to happen and cannot be avoided. Design changes are the primary contributor to disruption of time and cost performance of construction projects. Previous research in this domain lacks of detail studies on systematic review on the existing literature. This paper reviewed literature published in peer-reviewed journals and conference proceedings in the construction management field and had emailed several questions to the expert in construction industry. The objectives were to recognize the causes and impacts of design changes on project performance and to provide insights for future studies in Malaysian context. The findings indicate that design changes originate mainly from the owner side are identified as important causing factors to time overruns and cost overruns. This paper proposes framework for the management of design changes in construction projects.

Stakeholder Satisfaction

The Indian construction industry is facing challenges due to performance shortfalls. The construction projects are highly complex, distinctive, fragmented and do not have of well-established performance assessment models to evaluate their project success. Assessing overall project success is not possible to measure by single factor. To address this limitation, the Modified Project Quarter Back Rating (PQR) model was developed for the Indian construction industry. Modified PQR model’s output is a project score based on performance areas affecting project success and outcome. The model integrates ten performance areas that have identified through literature review. Performance areas included in the model are; (i) Cost (ii) Schedule (iii) Stakeholder satisfaction (iv) Safety (v) Quality (vi) Finance (vii) Environment (viii) Communication and collaboration (ix) Customer relation and (x) Productivity. These performance areas are measured through different performance metrics; i.e. performance metrics scores are aggregated to compute performance area scores. The model gives a single score that will help in comparing overall performance for different projects. This paper attempted to highlight the importance of performance metrics in modified Project Quarter Back Rating (PQR) based construction project performance assessment model for the Indian construction industry. The validity of the model needs assigning appropriate weights to the performance metrics as the weightage determines the relevance. Appropriate weights were determined using two round Delphi survey with 12 experts. Findings reveal that two performance metrics; return business from customer relation and OSHA recordable from safety have high weights. This modified PQR model will help key participants of the industry to compare the performance of various projects and to monitor performance areas that impact project performance rating.

Religious Elements

PurposeReligiousness is evident in every aspect of life, and its impact on construction project performance is undeniable. However, little has been done to fully understand the influences one's religiosity has on performance factors. This paper aims to explore the influence of religious elements on performance factors in the Ghanaian construction industry (GCI).Design/methodology/approachUsing a desk survey and closed-ended questionnaire, data were obtained from the three religious' bodies (Christianity, Islamic and Traditionalist) in Ghana. The analysis of the collected data was done using mean score ranking and regression analysis.FindingsIt was revealed that most of the religious bodies were aware of the presence of the seven factors identified for measuring construction project performance. The findings suggested that there was a significant and positive relationship between the religious elements (of all the three religions) and cost as well as schedule performance. Islam recorded the highest relationship in influencing public construction project performance relative to cost performances. Specifically, 1% increase in Islamic elements accounted for an 82.7% increase in cost performance. Traditionalists and the Christian religion had minimal significance in influencing cost performance. Furthermore, a 1% progress in Islamic elements accounted for a 45.8% increase in the schedule performance of construction projects and among construction professionals.Research limitations/implicationsThis study has provided better understanding of the religious views on project performance. This research has also provided pragmatic directions to project stakeholders to encourage religious groups to take critical look at the other performance factors that were seen not to be significant.Originality/valueThis paper represents a novel attempt to measure the influence of religious elements on project performance factors in the construction industry. A key contribution to the body of knowledge is that the study has proven that religious element has tendencies to influence cost performance and schedule performance in the construction industry.

Sustainable development of any country to some extent depends on successful accomplishment of construction projects, particularly infrastructures. Contractors have a key role in the success of these projects. Hence, the selection of a competent contractor as a complicated and hard decision process has a vital importance in the destiny of any construction project. Contractor selection is in essence a multicriteria decision-making that ought to encompass so many aspects of the project and the client’s requirements on one hand and the capabilities and past records of the contractors on the other hand. Failure in selecting a competent contractor may cause time and cost overruns; quality shortcomings; increasing in claims, disputes and change orders; and even failure of the project. In spite of deficiencies of selecting a contractor by the rule of “the lowest bid price”, it still prevails in many countries including Iran. In this paper, a new contractor selection model based on the best-worst method (BWM) and well-known Fuzzy-VIKOR techniques is proposed as a solution to overcome the deficiencies of the traditional “lowest bid price” rule. An illustrative example of a water channel construction project verified the applicability of the proposed model in practice.

The problems of material waste and cost overruns are common in the construction industry. These problems occur at different stages of a construction project, from planning, design to project completion. The argument on how to eliminate cost overrun has been on-going for the past 70 years as on-site wastage of materials leads to increase in the final project cost. This paper examines the relationship between the causes of material waste and those of cost overrun at the pre-contract and post-contract stages of a project. The desktop methodological approach was firstly adopted in comparing the causes of material waste and those of cost overruns from the literature, in order to determine the possible relationship. Subsequently, interviews were purposively conducted with construction professionals within Abuja, Nigeria, in order to verify the literature based information. The result reveals that all the causes of material waste also cause cost overrun at the pre-contract and the post-contract stages of a project. 96.88% and 81.81% of the causes of cost overrun also cause material waste at the pre-contract and post-contract stages respectively. Other causes which are not related are mostly, the micro-economic and macro-economic factors. These results are not different from those of the interviews conducted with professionals and summarised in the tick box. It was also found that to achieve Effective Construction Material Waste Management (ECMWM) for any construction project, material waste must be controlled at its sources and causes, and at different stages of a project. Based on these findings, it can be concluded that effective management of material waste would translate into a reduction in the level of project cost overrun. The study recommends that construction-project managers, as well as the construction practitioners should encourage the management of material-waste causes, as it has the potential to minimise cost overrun for projects.
