Delay Analysis in Construction Projects

Abstract

In India, construction is the second largest economic industry next to agriculture. The delay problem in construction industry is a worldwide phenomenon. Delays occur in most construction projects are either simple or complex. To avoid the project delay different factors causing delay should be analyzed and managed properly. This report discussed the delay in construction projects; hence various factors were considered which are responsible for delay in many projects. A questionnaire was prepared by considering the various factors that causes delay in the construction industry. The collected list contained 63 causes for delay which were categorized into seven different groups. This questionnaire was sent to different owners, consultants and contractors for the ranking of the various factors. This data was used to analyze “Frequency index, Severity index and Importance index” of different delay factors. The study aimed to provide the compilation of different views of researchers and results clearly showed that every group of researchers gave different ratings for various factors causing delay. The results were computed and hence the factors were ranked accordingly related to their chances/impact of delay in the construction project. From this study top five factors has been found which are responsible for delay in any construction project are: Equipment breakdown (Rank 1), Shortage of labour (Rank 2), Delay in sub-contractor work (Rank 3), Shortage of equipment (Rank 4) and Low productivity level of labors (Rank 5).
