Time overruns are major problems facing the Nigerian construction industry. It’s of high concern to those who are involved in the construction industry. This study was carried out to identify the major causes of time overruns in the Nigerian building construction industry, by means of a literature review and a questionnaire survey. A total of twenty (20) time overrun causative factors were obtained from the literature. The questionnaire survey was distributed to randomly selected respondents from a combination of clients, consultants, contractors, site engineers, project managers and sub-contractors. In all, one hundred and forty-one (141) questionnaires were distributed to randomly selected respondents (clients, consultants, contractors, site-engineers, project-managers and sub-contractors), one hundred and thirty-two (132) questionnaires were returned out of which three (3) questionnaires were found incomplete and invalid. Only one hundred and twenty-nine (129) questionnaires were found consistent and valid for use in this research. Relative Importance Index (RII) and Severity Index were used to carry out a ranking analysis. Based on the data received, the five (5) most severe factors influencing project handling overtime in Nigeria construction industries are Inaccurate evaluation of projects time/duration (91.9%), Risk and uncertainty associated with projects (91.6%), Complexity of works (87.6%), Weak regulation and control (86.8%) and Lack of financial power with severity (86.3%).

Cost overrun in construction projects is a common phenomenon in Iraq. This might occur due to diversity of factors. This study aims to identify the factors influencing construction projects cost that are potentially controllable by main contractors. A field study through a questionnaire survey was directed to a sample of related Iraqi professional engineers from general contracting companies at both public and private sectors. Their opinions on the impact and frequency of each factor were investigated. The questionnaire offered (59) factors classified in (8) categories namely; legislations, financial and economic, design, contractual, site management, material, labor and equipment. The factors were ranked according to the highest Relative Importance Index (RII). The study revealed (10) major factors that are potentially controllable by main contractors namely; labor productivity, sub-contractors and suppliers performance, equipment productivity, site organization and distribution of equipment, experience and training of project managers, scheduling and control techniques, planning for materials supply, planning for equipment supply, materials delivery and planning for skilled labor recruitment. Recommendations to aid contractors and owners in early identification of these factors are also included in this study.

PurposeManagerial shortfalls can considerably undermine the delivery performance of construction projects. This paper appraises the project management essentials (PMEs) for successful construction project delivery.Design/methodology/approachFollowing a detailed literature review, a questionnaire survey was developed encompassing 20 PMEs that were identified. An opinion questionnaire survey was used to facilitate data collection from key construction stakeholders in the Malaysian construction industry. The survey data were subjected to descriptive statistics and exploratory factor analysis.FindingsFindings indicated that the leading PMEs are competency of the project team, competency of project manager, good leadership, effective planning and control and realistic cost and time estimate. Spearman’s rank correlation tests affirmed a good agreement on the ranking of PMEs across stakeholder groups. The present study found that PMEs for construction have a total of four dimensions, namely: scope, communication and competence management; stakeholder commitment and collaborative engagement; construction time–cost planning and control; and environment, health, safety and quality management.Practical implicationsThe findings could potentially contribute to the development of appropriate project management best practices to address managerial shortfalls in Malaysia and other developing countries.Originality/valueThis paper bridges the identified knowledge gap about critical managerial dimensions for successful project management in construction. The present study adds to the existing body of knowledge around this under-explored area in the construction management literature.

Contractors are one of the important parties in completing a construction project as they directly involved in the construction works execution. Therefore, contractors’ performance should be monitored and assessed on a regular basis to ensure the success of the project, particularly by identifying the failures and shortfalls, as well as any delays and losses that might occur due to the poor productivity of the contractors. A systematic performance appraisal is one of the endeavours in ensuring that the contractors’ performance is as per the expectation of the stakeholders, particularly the client. Hence, this paper provides a review on the contractors’ performance appraisal practices in construction industry in Malaysia. Questionnaire survey on 214 respondents from construction industries, ranging from contractors to project managers, was undertaken where the results showed that contractors’ performance appraisal in a particular construction project is very essential as it drives the project towards better improvement and ultimate success.

PurposeConstruction delay is the most common issue and creates many adverse effects in any construction industry. This study has investigated the views of engineers, project managers and contractors on the causes of delay during a construction phase to identify potential delay factors, negative effects on project delivery and prioritize the delay factors.Design/methodology/approachAn extensive literature review and interview with construction stakeholders have been conducted to identify potential causes of construction delays and design a questionnaire survey. The final questionnaire was designed with 40 potential delay factors, and a total of 102 valid Bangladeshi construction stakeholders responded to it. The result was analyzed by the relative importance index.FindingsAmong the 40 delay factors, the top five most influencing delay factors are “delay in progress payments,” “rework due to mistakes during construction,” “lack of skilled labor,” “poor monitoring and control of activities” and “delays in the making of a decision.” The top five most damaging effects of delay are “time overrun,” “cost overrun,” “disputes,” “arbitration” and “litigation,” among ten negative effects of construction delay. All construction stakeholders believe that the owner-related, consultant-related and contractor-related groups are the first, second and third most important groups of delay factors.Originality/valueThe outcome of this study would enable the Bangladeshi construction industry to develop strategies to overcome delay factors and their harmful effects. By focusing on the outcome of this research and prioritizing the critical factors, the construction industry of Bangladesh will be able to minimize construction delay significantly and propagate the progress of the construction industry by delivering quality projects timely.

Leadership skills are required in any area, including the construction industry. Compared to conventional construction projects, the obstacles of practising leadership skills are more significant in sustainable construction projects. In the context of managing a project, a project manager is accountable for overseeing the project from the pre-construction phase to the post-construction phase. Nevertheless, project managers often encountered utmost difficulties in sustainable construction projects during the pre-construction phase. Despite that, improving leadership skills would emerge to boost project manager performance in managing sustainable construction projects. Thus, this paper aims to determine the improvement factors of leadership skills among project managers in the pre-construction phase of sustainable construction projects. A questionnaire survey was developed with 44 improvement factors of leadership skills among project managers in the pre-construction phase of sustainable construction projects, in which 153 experienced project managers in sustainable construction projects in Malaysia responded. Data were analysed using normality test, exploratory factor analysis (EFA) and reliability analysis via IBM SPSS version 24 software. The finding reveals that all improvement factors were significant to improve leadership skills among project managers in the pre-construction phase of sustainable construction projects. Hence, this paper's findings would assist project managers in grasping the improvement factors that can improve their leadership skills, particularly in sustainable construction projects.

A construction company must acquire regulatory permits and licences before granting project approval. The formal processes do not embrace all the stakeholders. While regulatory permits or licences are granted by government, local and statutory authorities, there is also the need for the hosting or local community to consent to a firm’s activities to complete the symbiotic relationship. This commitment of residents towards acceptance, approval and support for a project to exist within their community is known as a social licence. This paper investigates the application of the concept of social licence in the Ghanaian construction industry. A total of 102 questionnaires were used in the analysis. Findings based on the questionnaire survey of contractors, project managers, quantity surveyors, engineers and architects indicate that social licence is an emerging concept in the Ghanaian construction industry. The result also shows the limited grasp and restricted application of the concept. Only 37% of the professionals with some level of familiarity with the concept admitted to using the term social licence or its concept in the construction industry. There is a need for industry sensitisation and education to harness the benefits a company derives from acquiring a social licence. Keywords: Community; Construction industry; Construction professionals; Ghana; Social licence.

Despite the roles which small and medium construction enterprises (SMCEs) play in the Nigeria construction industry and the economy at large, extant research revealed that their participation in public procurement is poor as large firms have dominated the public procurement market. Previous studies have identified barriers responsible for their low participation and also suggested improvement measures. However, improvement measures best suited to dismantle/mitigate each barrier is not known. This study thus, assessed measures for improving SMCEs’ participation in Nigeria public procurement. The study collected data from 100 SMCEs in Nigeria, via a questionnaire survey. Mean/relative importance index was used for ranking the measures and ANOVA for checking difference between the studied measures. The result of the study revealed that E-procurement is the best measure for improving SMCEs’ participation in public procurement as it is best in dismantling barriers related to “problematic procurement procedure”, “lack of awareness of public procurement” and “legal issues/corruption”. Training which is suitable for eliminating barriers related to “lack of skilled employees and partners”, emerged as the second best followed by Division of Contract into lots that is best suitable for tackling barriers related to “lack of resources” which is contrary to previous researchers’ belief that it is the best measure. The study concludes that E-procurement, training and division of contract into lots are all suitable measures for improving SMCEs’ participation in Nigeria public procurement in their other of priority. The study’s findings show that it is desirous that the measures are applied together as none of these measures is singularly sufficient in dismantling all barriers to SMCEs’ participation in public procurement.
