Rapid development in construction industry had caused the increasing of construction waste. This situation brings many negative impacts towards the environment, cost, productivity, time, social and economy. The increasing of construction wastes is mainly due to the inefficient waste management practices in the construction projects. Hence, the effective management practices in handling construction waste should be highlighted. This study seeks to identify the waste management practices that are able to engender on-site waste minimization. As much as 54 practices had been found from previous research publications. Mapping technique was used to determine the frequency for each practice. This study have found five (5) significant management practices that need to be emphasized in order to achieve on-site waste minimization. The findings of this paper will help researchers to further investigate the significant management practices in minimizing on-site construction waste.
The construction industry is known as the most hazardous industry and has always been plagued with accident for a long time. Incidents or accidents that happened at construction sites has caused several drawbacks of project performance, such as delay in project completion, increase project cost, reduce productivity and create negative impressions to the organization. Therefore, it is crucial for employer to ensure safety and health at the workplace is taken care of to avoid accident. This paper presents the review of the factors affecting safety performance of construction project, focusing on project level. Among the most frequently cited factors that affect safety performance of construction project in project level are safety training, implementation of safe working environment and implementation of safe plant and equipment. The outcomes of the paper may serve as a starting point for further research in investigating the main.
Cost overrun occurs when the final cost of the project exceeds the approved cost at the time of tender. Cost overrun or budget overrun is one of the many problems facing by construction industry stakeholders in the construction of building projects in Sindh Province of Pakistan. To attain the main objective of the research, deep literature review was carried out whereby the total of 64 causative factors of cost overrun were identified in construction industry. A questionnaire was developed and distributed among 28 well experienced experts having more than 20 years of experience in handling building projects. Collected data was analyzed by average index method. The results revealed that significant causative factors of cost overrun in building construction projects include financial difficulties faced by client, slow information between parties, change in price of material, delay of design, poor site management, cash and payment problem faced by contractor, and delay in decision making. The findings from this research can help practitioners of building projects to find measures to mitigate or overcome these causative factors of cost overrun way before they can lead to damaging impact on project's cost performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
