Examining factors influencing delay of construction projects in Tanzania: A case of Gerenzani- Mbagala BRT road

Abstract

This study examined the factors influencing the delay in the Gerezani-Mbagala BRT road construction project in Dar es Salaam. Specifically, the study examined client and consultant related factors that resulted in the delay in road construction in the study area. The study was guided by resource-based theory. The study used a descriptive research design and adopted purposive and stratified sampling techniques to select 50 members of the sample of the study. On the other hand, a questionnaire and interview tools were used to solicit information from the respondents. Additionally, the appropriate model for data analysis was the logistic regression model. The findings showed that limited funds provided by the client and poor communication had statistically significant associations with project delays in the Gerezani-Mbagala BRT construction project. Also, the results revealed that a delay in approving major changes and a lack of experience among the consultants had a statistically significant influence on the delays in the Gerezani-Mbagala
BRT construction project. The study further revealed that delays in payments from the client and rework due to errors made by the construction personnel were significantly associated with project delays in the Gerezani-Mbagala BRT construction project. The study concludes that client-related and consultantrelated significantly caused the delays in the Gerezani-Mbagala BRT construction project. The study recommends that the client should provide enough time to produce project briefs and other feasibility studies, as this would lessen the impact of inaccurate project cost estimation, unforeseen site circumstances, and slow site clearances on the delivery of the construction project.
