Abstract

The paper reports on a study of the impact of traditional and design & build delivery methods to ameliorate schedule delays in the South African construction projects. A case study approach of two similar projects was adopted for the study. Data was compiled from document analysis and semi-structured interviews. Selection of projects was purposive and convenience based. A comparative analysis of the two projects was performed on delays to inform on which delivery method ameliorated better the impact of schedule delays. Findings were that design and build marginally reduced the impact of consultant related delays. Little impact was however found for client, contractor and design change related delays. Most construction projects suffer delays, which inevitably increases the contract sums. Reducing the impact of delays is therefore critical. Choice of a delivery method offers an opportunity to reduce the delays and therefore it is valuable to understand which delivery method offered better results. Findings underscore the importance of seeking alternative methods to improve performance. The design and build method seemed to perform better than the traditional method on delay reduction. The implication is that although clients prefer “safe” methods, alternative delivery methods offered better results.
