Purpose Buildability analysis has a potential of improving the outcomes of construction projects. However, the usage of buildability analysis is not well pronounced within the construction sector. This study aims to provide understanding of the concept of buildability analysis with the view to predicting the future stance for buildability analysis. Design/methodology/approach The study adopted a survey research method. Questionnaires were administered to purposively selected group of construction professionals working in Nigeria. A total of 82 questionnaires were administered among the sampled respondents, out of which a total of 51 (62.2%) were adequately filled and returned. The data collected were analysed using descriptive and inferential statistics. Findings The results revealed inability of the designers and constructors to have a common upstanding of the entire construction process, fragmented nature of the construction industry and poor correlation between design and construction as the most essential needs for buildability analysis. On the benefits of buildability analysis, the results showed increase in efficiency, save wasteful efforts and quality improvement as the most significant ones. In addition, the results from the study revealed that there is a statistically significant difference in some of the needs for and benefits of buildability analysis among the survey participants. Originality/value The study identified three future stances for buildability analysis to include building unity, efficient and effective construction and high competition. Framework for buildability analysis was developed aimed at providing guidance to professionals in achieving enhanced project production information. The findings provide in-depth insight of the needs for and benefits of buildability analysis that can inform professionals in the construction industry to adopt buildability analysis programme as a lasting solution to most design challenges and buildability problems confronting the sector.

Purpose Construction contractors serve as economic partners to owners of construction projects, but often times, they could depict opportunistic tendencies which are to the detriment of the client. This study aims to focus on the awareness of construction professionals with respect to influencing factors of construction contractors’ opportunism. Design/methodology/approach A questionnaire survey was adopted in eliciting responses from construction professionals, namely, architects, quantity surveyors, builders and engineers. In total, 337 questionnaires were distributed, of which 264 were retrieved and deemed fit for analysis. Methods of data analysis used are mean item score, factor analysis, analysis of variance, Kruskal–Wallis and Student Newman Kaul post hoc test. Findings The study revealed that the level of construction professionals’ awareness of contractors’ susceptibility of opportunism is very high. Equally, the most ranked factor is “No sanction for not reporting inconsistency of drawings.” The postulated hypothesis was subjected to a test, and the result showed that there is a significant difference in professionals’ perceived level of awareness of factors responsible for contractors’ opportunistic behaviors. Originality/value The study brings to the fore professionals’ knowledge of the awareness of influencing factors to contractors’ opportunism. The established level of its awareness portends a dangerous trend and has a large negative impact on the construction industry as this opens a vista to discouraging prospective investors, developers and owners, taking into cognizance the effect this would have on the economy.

Purpose – Rework is an endemic problem in construction projects and has been identified as being a significant factor contributing cost and schedule overruns. Causal ascription is necessary to obtain knowledge about the underlying nature of rework so that appropriate prevention mechanisms can be put in place. The paper aims to discuss these issues. Design/methodology/approach – Using a supervised questionnaire survey and case-study interviews, data from 112 building and engineering projects about the sources and causes of rework in projects were obtained. A multivariate exploration was conducted to examine the underlying relationships between rework variables. Findings – The analysis revealed that there was a significant difference between rework causes for building and civil engineering projects. The set of associations explored in the analyses will be useful to develop a generic causal model to examine the quantitative impact of rework on project performance so that appropriate prevention strategies can be identified and developed. Research limitations/implications – The limitations include: small data set (112 projects), which include 75 from building and 37 from civil engineering projects. Practical implications – Meaningful insights into the rework occurrences in construction projects will pave pathways for rational mitigation and effective management measures. Originality/value – To date there has been limited empirical research that has sought to determine the causal ascription of rework, particularly in Hong Kong.

PurposeThis research aimed to investigate the extent to which organisational culture is practised in local and foreign contractors in grade one and two categories and how it affects their performance.Design/methodology/approachThe approach for this research was positivist in nature adopting a mono-method of data collection through a survey using self-administered questionnaires. A total of 138 questionnaires were distributed among public clients and large-scale contractors registered in the stated grades, and 112 questionnaires were returned for analysis representing an overall response rate of 81% for contractors and clients.FindingsFindings revealed that in organisational culture, significant differences were found for management style and dominant characteristics of the organisation between local and foreign contractors. Differences were not found for leadership styles, measures of success and organisational glue. Results suggest that for local contractors to perform better, significant changes are needed to their management style and dominant characteristics of their organisations.Originality/valueForeign contractors in the Zambian construction industry are reportedly outperforming local contractors making them preferred contractors on larger public projects accounting for 85% of construction projects by value of works. This study presents the differences in organisational culture between foreign and local firms. It further demonstrates that organisational culture plays a key role in determining performance of a contracting firm. The study presents areas that local contractors can improve in organisational culture in order to remain competitive.

Purpose Furthermore, the purpose of this study is to compare the student engagement and the learning outcomes in offline and online PBL in the aforementioned course. The COVID-19 pandemic has caused disruption in various sectors, including education. Since it was first announced in mid-March 2020 in Indonesia, teaching and learning activities have been carried out online. In this study, a comparison of the offline (Spring 2019, prior to the pandemic) and online (Spring 2021, during the pandemic) problem-based learning (PBL) method in the sustainable chemical industry course is investigated. Design/methodology/approach A quantitative analysis was conducted by measuring the students’ engagement, course-learning outcomes (CLOs) and student learning outcomes (SLOs). Difference tests of engagement score, CLOs and SLOs were investigated by using the t-test or Mann–Whitney U-test. Furthermore, the perceived students’ stressors were measured. Findings It is found that the students’ engagement in offline and online PBL gives similar scores with no significant difference. This is possible because of the PBL structure that demands students to be actively engaged in gaining knowledge, collaboratively working in teams and interacting with other students and lecturers. Although similarly engaged, the CLOs and SLOs of online PBL are significantly lower than offline PBL, except for SLO related to oral and written communication skills and affective aspect. The decrease in CLOs and SLOs could be influenced by students’ academic, psychological and health-related stressors during the COVID-19 pandemic time. Originality/value This study provides a recommendation to apply online PBL during the COVID-19 pandemic time and beyond, although some efforts to improve CLOs and SLOs are needed.

Purpose Although there is a boom in the construction industry in the Kingdom of Saudi Arabia (KSA), it is yet to fully adopt building information modeling (BIM), which has received a lot of attention in the US, UK and Australian construction industries. Thus, the purpose of this paper is to provide the current state of the art in BIM implementation in Saudi Arabia, as well as perceived benefits and barriers through a case study. Design/methodology/approach A broad overview of BIM, the construction industry in KSA and the research and implementation of BIM in KSA was presented in this study. The research further established the perceived benefits and barriers of BIM implementation through a case study of a local AEC firm. A questionnaire survey was used to obtain lessons learned from the BIM team of the pilot project and was further analyzed using the RII approach. Findings The study’s findings include the lack of policy initiatives in KSA to enforce BIM in the construction industry, as well as the lack of sufficient research in the domain of BIM in KSA. Furthermore, the case study also revealed that the most important benefit of BIM adoption is “detection of inter-disciplinary conflicts in the drawings to reduce error, maintain design intent, control quality and speed up communication,” whereas the most important barrier is “the need for re-engineering many construction projects for successful transition towards BIM.” Originality/value The study provides a background for enhanced research towards the implementation of BIM in Saudi Arabia and also demonstrates the potential benefits and barriers in BIM implementation.

Purpose – With the increase in the cases of construction claims in Nigeria, many projects have remained uncompleted, while many of those completed receive poor client satisfaction. The purpose of this paper is to investigate how construction claims are managed. Design/methodology/approach – In total, 58 claim factors were identified and addressed to construction professionals through survey to indicate the extent at which the factors contributed to claims. A case study was conducted to illustrate claim management. Findings – In total, 37 factors were the major source of claims. Late payment, delayed approval of change order and delay cost were the extremely influential while the least were storage charges, loss of productivity, and costs of preparing claims. Evidences revealed that all stakeholders should play active roles to deliver “claim free” projects. Practical implications – The findings will be useful to practitioners in the effort to improve project delivery by providing some guidance on claim minimization. It is hoped that this study will encourage academics to conduct more research on this issue. Originality/value – There is no known conclusive empirical study on construction claim factors in Nigeria. In light of this, the findings offer greater opportunities for claim minimization/avoidance.

Purpose This study aims to understand the construction process of an organizational identity in a hybrid organization. Design/methodology/approach The author developed a single case study based on in-depth interviews, non-participant observations and document analysis in a credit cooperative. Findings After periods of changes in organizational identity (from idealism to pragmatism), the formation of a paradoxical organizational identity was observed in which the core value became a central polarity between idealism and pragmatism; after periods when members engaged in actions that promoted resistance or change, they framed past events in a story of stable dynamics between idealism and pragmatism; and pro-distinctiveness and -similarity forces in relation to other organizations were reconciled in a quest for optimal distinctiveness that simultaneously enabled the development of uniqueness and adequacy. Originality/value This is the first study to adopt a paradox perspective to analyze the identity of a cooperative.

Critical Success

Purpose The decentralisation of information and high rate of mobile content access in the construction industry provides an ideal scenario for improvement of processes via the implementation of the paradigm of the Internet of Things (IoT). Smart devices are considered as the objects interconnected in the IoT; therefore, they play a fundamental role in the implementation of digital solutions during the execution of construction projects. The purpose of this paper is to assess the critical factors for a successful implementation of smart devices in the construction industry. Design/methodology/approach An empirical study was performed in the Dominican Republic. This country, located at the heart of the Caribbean, presents an economy that strongly relies on the construction industry. Following a systematic approach, a qualitative data collection and analysis was performed based on semi-structured interviews and content analysis to professionals of construction companies in the Dominican Republic, enquiring the concept of smart devices and critical success factors for implementing the devices in the industry. Findings The key success factors obtained from the contestants were leadership, technology awareness, company size, usability of proposed solution, cost of implementation and interoperability. Originality/value This paper provides information to clients of the construction sector regarding the benefits of embedding smart devices into their business activities. Furthermore, this study provides a better understanding of the key factors to be considered by construction organisations when embedding smart devices into their projects. This study also provides recommendations for distinct stakeholders of the construction sector, such as policy makers, clients and technology consultants. Policy makers should especially consider factors such as technology awareness and leadership to develop the right policies for the integration of the IoT in construction projects. Technology consultants should be aware of the latest case studies of successful implementation of smart devices and IoT systems in the world in order to adapt and implement smart devices and IoT in their projects.

Purpose – The purpose of this paper is to evaluate the waste occurrence level in the construction industry. It includes: first, identifying the mean value of frequency of waste occurrence according to respondents’ characteristics; second, identifying the main predictive factors for waste occurrence based on latent relationships between initial waste factors; and third, identifying the waste occurrence-level indicator (WOLI) for the construction industry based on the main waste measurement factors. Design/methodology/approach – A total of 19 waste factors were sorted from the literature review. A structured questionnaire was adopted to carry out the survey. The respondents are professionals who have much experience in construction and management of project. Shapiro-Wilk test of normality, Levene’s test, ANOVA test, and factor analysis technique were used to analyze the collected data. Findings – Frequency of waste occurrence in construction projects is quite high. There was no statistically and practically significant difference in means for waste occurrence between selected population categories. Based on factor analysis technique, there were five principal components extracted with 56.7 percent of total variance. The WOLI in the construction industry was found as 61.55 per the scale of 100. Research limitations/implications – The non-probability sampling was applied to collect data because of several certain limitations and difficulties. The number of data sets is relatively small. This study has only examined the frequency of waste occurrence without quantitative information. Practical implications – This is another study of waste factors in the construction industry, which is different from traditional waste studies. Originality/value – The contribution of this study to the practical project management is that a proposed evaluation sheet for WOLI could be applied for any construction firm.
