Abstract

Building and infrastructure projects at the North-West Province Department of Public Works and Roads (NW DPWR) often perform poorly in terms of overrunning both the original approved timeline and the budget. Adding to poor time and cost performances, these projects often do not meet the desired functional requirements. This article reports on findings of a study which investigated the causes of these poor performances in the NW DPWR. Fifty potential causes of poor performance were identified from literature. These factors were grouped under three main related categories of owner-related, contractor-related and consultant-related and were subjected to a questionnaire survey to identify the most critical causes of failure. The results were analysed using the Relative Importance Index (RII) and Spearman’s Rank Correlation Coefficients. The results indicated that the most significant causes of poor building and infrastructure project performance in the NW DPWR include underestimation of project cost, the lack of experience in executing projects, contractor’s cash-flow constraints, corruption and bribery during the bidding and contract award phase, as well as poor site management and supervision. Recommendations are made to prevent similar causes of projects failure in the NW DPWR in future.
