However, the industry has been adjudged as a slow adopter of digital technologies such as big data analytics (BDA) to improve its service delivery. The implication of this slow adoption is the lack of innovativeness and unsustainable project delivery that has characterised the industry in most countries, particularly in developing ones like South Africa. Therefore, this study assessed the intention to adopt BDA by construction organisations using the unified theory of technology adoption and use of technology (UTAUT) model. A post-positivism philosophical stance was employed, which informed the use of quantitative research with a questionnaire designed to solicit information from construction organisations in South Africa. Data analysis was done using Cronbach alpha to test for reliability and Fuzzy Synthetic Evaluation to evaluate the impact of the different constructs of the UTAUT on the adoption of BDA by construction organisations in South Africa. The study found that variables relating to facilitating conditions, performance expectancy, and social influence will significantly impact an organisation’s intention to adopt BDA. However, issues surrounding effort expectancy, resistance to use, and perceived risk cannot be overlooked as they also have high impact levels. The study provides an excellent theoretical and practical contribution to the existing discourse on construction digitalisation.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2021-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83569084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lean construction (LC) has been widely accepted as a robust philosophy to enable sustainable construction (SC) practices. However, the existing literature is more inclined toward defining the integration between LC and sustainability through LC practices and techniques. Little research tackles the challenges of achieving sustainable goals within the current practices. Therefore, this paper aims to present a strategy that can help the construction industry overcome the challenges of SC in the traditional construction management practice by using LC. The challenges of SC are identified through a systematic literature review approach with metadata analysis. Compared with LC principles, tools and techniques, the strategy focused on identifying (1) the power and potential of LC principles and (2) the best LC practices/techniques that help in overcoming these SC challenges. The study results showed 20 out of 32 challenges identified can be overcome by using LC integrated with SC. Finally, a Lean Approaching Sustainability Tools (LAST) matrix is developed to provide guidelines to the construction stakeholders for the selection of LC practices/tools/techniques in overcoming the top 15 most important challenges.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2021-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73426203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whilst sustainability is receiving significant attention in construction sectors in developed countries, this seems to be less true for developing countries. Thus, this study explores the challenges faced by the construction sector in one such developing country, Libya, in integrating sustainability practices into its common scope of activities. The study adopted a mixed research approach consisting of a questionnaire survey and expert interviews. Completed questionnaires (134 No.) were analysed using statistical techniques. The findings from the survey informed the topics for the interviews with 10 experts where the collected data were analysed through content analysis. The outcomes of the research explained that the awareness of sustainability in construction was weak in the practice of the Libyan construction sector. Additionally, the failure of supporting institutions to create an effective application of sustainability guidelines, lack of stricter legislation, building codes or standards were also found to be major challenges. The study contributed to knowledge by providing a better understanding of sustainability and clarified the main challenges faced by the stakeholders and which they have to consider in order to improve sustainable construction in Libya. The practical implications of the study include the strategies identified to avoid or minimise the challenges and their consequences.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2021-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72466572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among various strategies that are proposed to enhance construction safety, Lean construction practices were widely implied and proved to be effective. However, the link between Lean implementation and construction safety has not been completely studied yet in previous research in terms of psychological safety context. This study implies that psychological safety is of utmost importance in terms of explaining the association between Lean and safety. Lean implementation elements such as respect for people, trust, leadership, and continuous improvement positively affect employees’ psychological safety. In this context, semi-structured interviews and a survey were conducted with employees working in U.S. construction companies. The interviews provided that the majority of the construction employees do not feel psychologically safe at their workplaces either in traditional or Lean construction projects due to a number of reasons such as heavy workload, and deadline pressures. However, it was found that construction workers feel safer psychologically in Lean construction projects compared to traditional projects. According to the interview results and literature review, a conceptual model was proposed. Therefore, this study can contribute to the research area of psychological safety in the construction industry.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2021-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77125454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study attempts to investigate the relationship between encouragement-based management mechanism (EMM) and manpower development (MD) in construction firms and examine the moderating effect of firm size on this relationship by conducting bivariate Pearson correlation and hierarchical multiple regression analyses to analyse empirical data collected from 79 construction firms in Vietnam. The results show that EMM positively affected MD, and this positive effect was stronger in small/medium-sized construction firms than in large firms. The findings could provide construction firms in Vietnam, as well as other developing countries, with a better understanding of the effect of EMM on MD. Hence, they could establish appropriate and wise encouragement-based strategies to enhance their manpower. This study could contribute to the extant literature on construction manpower development by providing empirical evidence of the EMM−MD relationship in the context of construction firms. 58 DECLARATION OF CONFLICTING INTEREST The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

As a result of the dynamic complexities inherited in construction projects, changes in the scope of work are inevitable. Of particular concern is that, when scope changes are introduced in a project, contractors follow a systematic procedure in managing the changes, but with poor planning and implementation thereof because the project complexities that underpin the scope changes are not fully understood. Therefore, despite that complexity is an inherent and defining feature of construction projects, studies in the literature have failed to grasp and present the dynamics of project complexity which underlie the scope changes in the delivery of construction project.

As a result, generalizations remain sketchy, and a better understanding is needed. This study lends a voice to the literature’s debate by introducing the part played by institutional pressures. The aim is to evaluate the impact of internal organizational factors and institutional pressures on a Syrian construction firm’s performance outcomes, with institutional pressures playing a mediator’s role. Data were collected using a questionnaire instrument from a sample of 197 building experts working in large public construction companies in Syria and analysed using the partial least squares structural equation modelling (PLS-SEM). The results reveal that leadership style and effective communication have a significant and positive effect on construction firm performance outcomes. However, the effect of team competency and skill was not supported; nonetheless, providing institutional pressures as a mediator into the relationship made it significant, thus, providing a vital theoretical contribution worth considering in future research. Practically, this study is the first attempt at evaluating organizational factors and institutional pressures as a critical determinant of organizational performance that should interest management at organizational levels. 81 DECLARATION OF CONFLICTING INTEREST The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.
