Expressway Construction

Expressway construction projects are one of the crucial infrastructure projects for a country. Hence, assessment of environmental and social implications prior to initiation of the expressway construction project is vital. Thus, the research aims to analyse effect of social and environmental factors on expressway construction in Sri Lanka. Initially a comprehensive literature review was done to discuss on expressway construction in Sri Lanka and environmental and social implications of expressway construction in global context. The study followed a qualitative approach. Hence, four expert interviews were carried out to explore more on the same context limiting to Sri Lanka. Experts were selected from only on-going expressway project in Sri Lanka, central expressway project. Moreover, collected data were analysed through manual content analysis. The study findings highlighted viaduct construction, land acquisition and rock blasting as the major activities relating to environmental implications of the expressway construction projects. Thus, rational, logical, scientific, and technical selection of the routes is the most effective and efficient mean in minimizing adverse impacts. Hence planning of these activities should be done with due care by authorities only after proper feasibility studies. Further, major factors affecting social implications of the expressway construction have been identified as settlement, livelihood, public infrastructure and health and safety. Hence, resettlement action plans need to be updated to comply with the identified requirements through environmental and social factors.

Purpose The purpose of this study was to investigate the perceptions of construction professionals relative to factors that affect the delivery of optimum health and safety (H&S) on construction projects during the COVID-19 pandemic. Design/methodology/approach The study adopted a quantitative design which entailed the distribution of a web-based questionnaire among construction professionals, namely, architects, construction/project managers, engineers, H&S managers and quantity surveyors working for contractors and construction consultants in Zimbabwe. The data were analysed with descriptive and inferential statistics. Factor analysis was used to reveal interrelated significant sets of factors affecting the delivery of optimum H&S. Findings Factor analysis revealed nine components/factors: change and innovation-related, monitoring and enforcement-related, production-related, access to information and health service-related, on-site facilities and welfare-related, risk assessment and mitigation-related, job security and funding-related, cost-related and COVID-19 risk perception-related factors as the significant factors affecting the delivery of optimum H&S during the COVID-19 pandemic in Zimbabwe. Research limitations/implications The results highlighted the need for social dialogue among construction stakeholders to support initiatives that will enhance the delivery of H&S on construction projects. Construction stakeholders may find the results useful in highlighting the areas that need improvement to protect workers’ H&S during the pandemic. However, the small sample limits the generalisability of the results to construction sectors in other regions. Originality/value The study investigated factors affecting the delivery of optimum H&S during the COVID-19 to inform interventions to enhance H&S.

In highway construction projects, labor-oriented work is an integral part of the management process, requiring analysis of factors affecting labor productivity during Covid-19 pandemic. This research identified 53 influential factors affecting construction labor productivity at selected cities and towns in Cagayan Valley Region, Philippines. Due to the pandemic, the construction industries incurred substantial profit losses. More so, the construction workers are too much affected because of the Enhance Community Quarantine (ECQ) imposed by the local government. Results indicated there was laxity on the Covid-19 protocols. No health worker in the project site ranked the highest in the health & safety factor group with an RII of 0.97 and ranked 1st among 53 factors on the different groups. Besides, no safety engineer was assigned to the projects and ranked 2nd with an RII of 0.93. Among the 7 groups of factors, the health and safety group ranked 1st with 0.81, followed by the schedule compression group with an RII of 0.78. Hence, these two groups of factors have a strong relationship, as evidenced by number of workers reduced. It was learned that the contractors’ strategy was to increase the number of working days to cope with their schedules. Hypothesis testing supported that there are various significant factors influencing labor productivity loss during the Covid-19 pandemic, as suggested by more than 50% of the respondents.

Purpose This paper aims to analyse the factors affecting the performance of large construction projects in Sri Lanka. The causes, impacts and mitigations in association with the critical factors are explored and discussed. Design/methodology/approach The research focuses on the evaluation and perspectives of clients and contractors of large projects in Sri Lanka. Combined quantitative and qualitative methods were applied in this research. Initially, a questionnaire survey was conducted with clients and contractors involved in large projects to evaluate the factors affecting the performance of projects and to identify the ten most critical factors. Interviews with the clients and contractors of three large projects were conducted to examine the causes and impacts of the critical factors and the approaches used to mitigate them. Findings Significant differences in the factors were observed for more than 40 per cent of the total factors under study, the contractors assigning more weight to most of the factors than the clients. The study identified nine internal factors and one external factor as the critical factors. Of these, seven were related to the contractors, which suggested that the contractors have greater roles in defining performance. Lack of management and technical skills of the parties involved, human capacity, lack of understanding and knowledge of the local context, changes in government policies and political interference were identified as significant causes of the critical factors. Originality/value The study analysed the factors affecting the performance of large projects in Sri Lanka, which, at the time of research, had just ended a 26-year-long civil war and was pushing the construction of large projects to be competitive. The challenges faced in this effort were explored as lessons learnt that might improve the efficiency and effectiveness of infrastructure development in Sri Lanka. The combined quantitative and qualitative methods applied in this study are expected to provide new insights in the project performance research, especially the interviews of the critical factors to gain an understanding on how the factors occurred and manifested themselves in real projects. The findings are, however, expected to be applicable to other developing countries that are currently aggressively developing their large infrastructure.

Research Findings

Project delivery systems (PDSs) selection is crucial to construction project management success. The matching between construction projects and PDSs is hypersensitive to project external environment. Existing studies on selecting PDSs mainly focus on owner’s and project’s characteristics and attach less attention to project environmental factors. This study, therefore, aims to formally identify key project external environmental factors affecting PDSs selection using a data-driven approach. Key factors are summarized and identified through the granular computing method based on 61 Chinese project samples. Empirical results indicate that four factors including market competitiveness, technology accessibility, material availability, and regulatory impact are critical to PDSs selection. This study extended previous research findings on PDSs selection from a perspective of project external environments. Research conclusions can be used as references underpinning construction owners selecting appropriate PDSs considering project external environmental factors.

Achieving and maintaining quality values are indispensable for attaining organizational and customer satisfaction. This research investigates different aspects of operationalize quality culture and factors affecting the quality of building construction in under developed countries like Pakistan. A qualitative and quantitative survey was circulated among different stakeholders including Clients, Consultants and Contractors to assess the level of the contractor’s performance, the project monitoring and controlling techniques, proper health and safety requirements, client satisfaction and workers experience in construction industry projects. The practice of professional quality management in building projects is increasing, however, many flaws and negligence are still found in local practices. This analysis also indicates that political and socio-economic factors play a significant role in maintaining the quality level in local industry. Therefore, the allocation of sufficient resources, proper training of workers, and recruitment of quality control staff and the use of advanced technologies are recommended for proper implementation of QMS (Quality Management System).

Abstract Labour productivity is key to the success of every construction project. The paper seeks to determine the factors that affect labour productivity and proffer possible ways to improve it in building construction projects. The study was preceded by a literature review. Data used were primary data collected through the use of questionnaires. The total number of respondents was 175. Snowball sampling technique was used in sampling respondents. Factor analysis was performed on the data collected and mean scores were also generated. The findings of the study showed that the use of wrong equipment, misuse of time schedule, lack of training sessions, poor site organisation, lack of motivation for workers, delays in the supply of materials and rework were the critical factors affecting labour productivity in building projects of Ghana. However, the major ways of improving labour productivity in building construction projects, according to the study, were to correct bad behaviour that negatively influenced productivity, proper layout of site, to improve health and safety, to use proper materials handling systems and to set targets for employees. Management must put structures in place to restrict human, material and construction related factors. This is because giving concessions in these areas can take a toll on productivity.
