A good knowledge of project complexity at the construction phase of a project, as well as a well thought out plan to manage complexity will determine how proficiently construction projects are planned, managed, and executed in an environmentally friendly manner. The level of complexity of construction projects to a large extent determines the performance or otherwise of the projects with regards to achieving specific environmental standards. At construction sites, the effects of adopting green site practices on environmental performance is largely dependent on the level of complexity inherent in the project’s construction processes. This study investigates the moderating effects of project complexity on the relationship between various green construction site practices and environmental performance of construction projects. A survey was conducted on class A contractors in Nigeria and 168 usable responses were received. The data were analyzed using the partial least squares structural equation modelling technique. The results show that project complexity moderates the relationship between waste management and environmental performance, and the relationship between materials management and environmental performance. But project complexity does not moderate the relationship between energy management and environmental performance. The study provides important theoretical and practical information for construction managers in understanding the dynamics involved in managing of projects with different degrees of complexity, while adopting certain green site practices with the aim of delivering projects with high degree of environmental performance.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":"25 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78347392","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}

Three tools are compared to determine the extent to which ergonomic tools can reduce the risk of injury to the back and wrist in steel-tying. A whole body system of wearable sensors was used to measure biomechanical risk in tying. Three tools were assessed to determine their impact on the risk of work-related musculoskeletal injury when used at different heights. These were: a conventional pincer-cutting tool; a power-driven tying tool, and a long handled stapler tool. \u0000No tool was found to work best in all situations. The long handled stapler tool significantly reduced trunk inclination when used from ground to shoulder height, but produced higher trunk extension (backward bending) when used above shoulder height. The power tying tool did not reduce the need to bend when working at lower work heights. The power-tying tool produced significantly lower peak wrist flexion values compared to the conventional pincer-cutter tool at all work heights except overhead. The power tying tool involved significantly lower levels of wrist rotation than the conventional pincer-cutter tool at all work heights above knee level. \u0000Many assessments of ergonomic risk factors in construction rely on observational methods. The use of small, lightweight wearable sensors permits the objective measurement of biomechanical risk factors for work-related musculoskeletal injury, as well as providing objective performance data that can be used in the design and selection of task-specific tools. Our analysis of work by height also provides insight into the way in which risk factors and reduction opportunities afforded by different tools vary depending on the height at which work is to be performed.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":"1 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2019-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75975760","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}

As part of a wider intervention study to improve the safety practices of the SMEs, this study has taken the first step in identifying the barriers and strategies to improve the safety practices at construction sites in Malaysia. The study has been conducted using various approaches (workshops, site observation and questionnaire survey) that have enabled the triangulation of information. The findings highlighted that the main barriers to good safety practices are the implementation costs, poor safety culture and lack of safety commitment from the client. The proposed solutions include introducing safety as one of the construction KPIs, creating more safety-conscious culture and establishing a funding mechanism to support the cost of safety training. Subsequently, several recommendations have been provided by collating inputs based on the barriers, strategies and drivers through three-party collaboration (authorities, industry and academia) in creating a collaborative movement towards enhancing safety practices among the SMEs. The fresh insights from this study would enable authorities and SMEs to be more proactive, rather than reactive in improving safety practices in the construction industry.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":"15 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2019-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87588668","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}

For decades, public entities have been known for a lack of compliance that manifest in: poor performance, poor personnel management, poor resource utilization and unprofessionalism. In Uganda, this has resulted in several restructures aimed at improving service delivery. Despite this, compliance remains an issue. The purpose of this study is to establish factors affecting compliance within a public procurement regulatory framework in public road construction projects and foster economic development. A cross-sectional research design including a structured self-administered questionnaire survey and PLS-SEM data analysis by SmartPLS3 was conducted. The research reveals that three factors positively affect compliance with a regulatory framework that govern public road construction projects; sanctions on staff, inefficiency of the public procurement regulatory framework and contractors’ resistance to non-compliance. While a further three factors have little positive effect on compliance; familiarity, monitoring activities and professionalism. Hence, the research contributes to construction management by showing that sanctions, perceived inefficiency and contractors’ resistance significantly enhance compliance within a public procurement regulatory framework.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":"40 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2018-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84045244","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}

At present, the lack of BIM in tertiary education has been the rising concern around the world as the demand for BIM talent increases. The current landscape suggests that few pedagogic researches have been undertaken to advance BIM education, particularly in Malaysia. BIM implementation could only be possible by identifying the potential barriers, which is a basic pre-requisite for successful adoption of BIM. Unfortunately, previous studies on the barriers of BIM adoption have often based on theoretical constructs, which are deterministic in nature. The methodology used could not portray a conclusive correlation of causal relations among the variables, creating difficulty in developing holistic and workable solutions. Therefore, this study aims to develop a methodology that provides a dynamic representation of the barriers in implementing BIM in tertiary education. The methodology combines both the deterministic (feedback from questionnaire survey) and dynamic approach (causal loop diagram). Data was first collected and analysed through a questionnaire survey administered among lecturers from selected Malaysian universities. Following that, a dynamic systems approach (causal loop diagram) was used to demonstrate the complex nature and interrelationship of the barriers for a more holistic representation. Results from the deterministic analysis has suggested barriers that relate to technology, while findings from the dynamics has identified the people aspect as the core barrier for BIM adoption. This study has contributed in establishing a methodology that integrates the dynamic approach with the deterministic data towards providing a more holistic representation of a system that further enables the identification of holistic solutions that would address the core barriers inhibiting the implementation of BIM education, particularly at Malaysian Universities.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":"72 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2018-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91160335","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}

The study was conducted by considering construction industry in the Eastern Cape of South Africa and using a survey research method and conceptual System Dynamics (SD) modelling. Findings reveals that investment, wage challenges, talent management, work environment, training, experience, and Government policy are the important challenges for the skilled labour shortage. Inadequacy of skilled labour considerably impacts the quality of work, productivity, and scheduling. The causal loop diagrams show that enhancement in investment in the labour wages will strengthen the availability of skilled labourers leading to higher productivity, and vice versa. Talent management based on appropriate recruitment and retention policy, staff development programmes and investment in these aspects will augment the skilled labour pool. Also, a better work environment through a policy of health and safety, investment in working condition and supported by Government policy will reduce the attrition of the labourer because of job dissatisfaction, which consequently will reduce the skilled labour shortage in the industry.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":"22 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2018-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82560753","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}

The aim of this study is to identify important factors for incorporating spatial data into the BIM at the preconstruction planning stage. Three rounds of the Delphi method were employed to obtain a consensus among twenty construction industry experts, selected through purposeful sampling.

However, it has been established that JV projects have experienced unsatisfactory performance leading to clients’ dissatisfaction. The purpose of this paper is therefore to determine the critical success factors (CSFs) influencing the performance of JV construction projects in South Africa. A positivist philosophy position was adopted using a structured questionnaire survey administered to the construction professionals. Prior to the main study, a content validity of the questionnaire was achieved using a pilot study. The data was collected from 115 conveniently sampled respondents, and analysed using principal component analysis and multiple regression analysis. The exploratory factor analysis revealed two empirical models to be tested; namely the first and second order factor models. The result of the first order model revealed that, management control influenced achievement of project objective of JV, whereas, the second order model established that understanding of contractual agreement, which was explained by six components of CSFs influenced achievement of project objective. It is suggested that stakeholders who prefer to be involved in JV projects should acquire good understanding of the contractual agreement in managing JV projects in order to successfully achieve the project objectives. This study adds to the discourse and literature on CSFs of JVs. It provides new empirical evidence of the CSFs that influence project performance outcome of JV in the context of South Africa which can also be replicated in other countries globally.

However, there is little research into the nature of crew work practices. This paper aims to unveil the influence of onsite crew work practices on productivity. An exploratory case study investigated work practices on a residential project involving two separate crews (of 18 and 23 workers) engaged in rebar placement for 112 columns each, which included a high-performing and an average-performing crew. A triangulated mixed methods approach to data gathering utilised site observations, individual and group interviews, and time measured work studies, to assess productivity of the crews. The findings indicate that the high-performing crew achieved 44% higher productivity than the average-performing crew and this manifested across specific tasks including rebar cutting, bending, stirrup fabrication and tieing. Five broad work practices were observed to significantly influence the above productivity differences: work preparation and execution strategy; group formation and stability; avoiding duplication of tasks; crew social cohesion; and internal and external leadership practices. These five practices are proposed as dimensions that can be used to measure crew productivity in ongoing research. In-depth understanding of crew based work practices will enable training of foremen and work crews in such practices to systematically develop high-performing crews.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":"11 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2018-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82815041","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}
