CAUSES OF DELAY IN CONSTRUCTION OF HIGHWAY PROJECTS: A REVIEW

Construction is an essential process for all of the developing countries. Moreover, highway and infrastructure construction projects are rigid development in a country. Delay is a common phenomenon in the construction industry which directly impacts the cost and quality of the project. Delays can only be reduced when the causes and its influences are identified and analyzed. In the past, most researchers have been working on finding the causes of delay in the construction project through several method and analysis. Nevertheless, the study on the delay causes and its influences towards the infrastructure and highway construction project is still limited and require more precise attention on it. The main objective of the study is to find the significant factors causes delay in the construction project especially in highway and road construction projects. Thus, the review methodology based on the frequency of occurrences of the factors causes delay in the highway and road construction project were significantly analyzed. This paper contributes a deep review on the factors that cause delay in the construction industry especially in the construction of highway and road projects. The top most significant factor causes delay in construction project was poor project planning and scheduling with the highest frequency of occurrences and percentage value which is 25 and 2.5% respectively. Therefore, this findings will be useful for future planning and time management in order to minimize the delay occurrences on the highway and road construction projects.
