Purpose The purpose of this paper is to develop a framework for value management (VM) implementation by establishing the effect of critical success factors on current construction practices. This will aid stakeholders to improve productivity of construction practices in the Nigerian construction industry. The study established the requirements that ought to be satisfied for VM to successfully enhance productivity of construction activities. Design/methodology/approach Data collection was based on self-administered questionnaires from 344 registered construction professionals in Nigeria. The Statistical Package for Social Sciences version 25 and structural equation modelling were used to analyse the data for both descriptive and inferential analyses. Kaiser-Meyer-Olkin measure of sampling adequacy revealed that the internal consistency of the developed research instrument was appropriate, while the confirmatory factor analysis indicated satisfactory goodness-of-fit indices among acknowledged determinants of the structural model. Findings A framework that established the requirements for the successful implementation of VM construction practices in the Nigerian construction industry. Originality/value A structural model validated the requirements of applying VM on current construction practices. The established requirements (environment, people, government and information/methodology) can be used by decision makers and stakeholders to improve productivity of the current construction practices in the Nigerian construction environment. A framework was developed and validated by construction experts to confirm its suitability, usefulness and acceptance.

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.

Background: The construction industry in Nigeria, is pigeonholed by poor quality of construction products as a result of the inherent corruption in the country. Lack of purposeful leadership and inappropriate choice of leadership styles in the industry have been attributed to project failure. Abandoned and failed projects are more predominant in the public sector which litters every corner of the country. Objectives: The objective of this paper is to assess the impact of leadership styles on quality performance criteria of public projects in Nigeria. Methodology: A total of 43 questionnaires were distributed to 3 key groups of respondents (Quantity Surveyors, Builders, and Architects) who are project managers in Nigeria. Descriptive and Inferential statistics were used to analyse the data using the Statistical Package for Social Sciences (SPSS). Likert Scale was used to measure the independent variables (leadership style): facilitative, coaching, delegating and directing; and the level of achievement of projects based on the dependent variables (quality and function performance criteria) which are: achieving highest aesthetic quality; and functional building that fits its purpose. Findings: The study revealed that Directing is the major leadership style used by project managers in Nigeria. Amongst the leadership styles which has the most impact on quality performance indicators is also directing which has the most relative influence on achieving highest aesthetic quality and functional building that fits its purpose. Conclusion/Recommendation/Way forward: The underlying relationship between Directing leadership styles and the performance criteria of achieving highest aesthetic quality and functional building that fits its purpose will be beneficial to the Nigerian construction environment.

Over the last decade, digital applications and Building Information Modelling (BIM) have been introduced in the construction industry to realize a smart construction ecosystem. However, the construction industry has not completely accepted BIM as a standard, and the concept of using BIM applications in universities has not been thoroughly researched. This paper addresses the first scientometric study of BIM education in universities, identifying the state of BIM education practices, skillsets, and the level of BIM education in universities. The paper used scientometric analysis and the VOSviewer mapping technique to assess the most impactful publication sources with the most important impact on BIM education by searching “BIM Education” and using 250 bibliographic data extracted from the Scopus database from 2011-2020 to identify the existing research gaps and research direction. Second, a structured questionnaire was distributed to 343 Year 2 and Year 3 students from two public and two private Malaysian universities that use BIM in their learning. Descriptive data analysis using cross-tabulation in SPSS and relative importance index (RII) were used to analyze the data. The paper revealed two stages of BIM education research; and identified research gaps in the fields of BIM education, architectural education, e-learning, curriculum and information management. The paper also revealed Revit, Cost X and the Glodon Cubicost software as the most used applications, while the common skillsets are design authoring, modelling, and cost estimation. However, both public and private university students mainly design 3D models at BIM Stage 1. The study recommends that institutions and other stakeholders provide continuous BIM training, purchase BIM software, and integrate BIM into the curriculum of Built Environment higher learning institutions for the next generation to be the generation that uses virtual collaborative platforms

PurposeThe purpose of this study is to explore existing literature on Building Information Modelling (BIM) in Malaysia and examine the perception of practitioners about the potential of BIM applications in reducing construction waste and enhancing productivity.Design/methodology/approachFirst, using 244 bibliographic data extracted from the Scopus database, the paper used scientometric analysis and VOSviewer mapping technique to assess the most impactful publication literature on BIM in Malaysia to identify the existing research gaps. Second, using a structured questionnaire, a total of 100 questionnaires were distributed to practising practitioners who incorporate BIM in the delivery of their projects. Descriptive analysis using cross-tabulation in SPSS software, radar chart, relative importance index and Pearson’s correlation were used to analyze the data.FindingsThe research gaps are in the fields of construction projects, buildings, energy efficiency, lifecycle and housing. The findings of the survey indicate that quantity take-off, clash detection, site utilization planning, digital fabrication as well as 4D stimulation were the main BIM applications used among the practitioners in Johor and Selangor.Practical implicationsBy assessing the state-of-the-art of BIM and BIM applications in this region, the practical implications of this study provide useful insights to construction stakeholders, funding organizations, policymakers, research institutions, professionals, journal editors, reviewers and researchers to understand the overall trend of BIM in Malaysia and its usage.Originality/valueThis paper is the first to use science mapping using scientometrics to reveal the current BIM research in “Malaysia only”. Relying on the identified gaps, the study further examined the usage of BIM applications in Malaysian construction projects.
