Abstract
Delay to contractors’ progress, often resulting in time and budget overruns, is one of a major source of claims and disputes in the construction industry. At the heart of the matter in dispute is often the question of the extent of each contracting party’s responsibility for the delayed project completion and extra cost incurred. Various methodologies have been developed over the years as aids to answer this question. Whilst much has been written about delay, there is limited information on the extent of use of these methodologies in practice. The research reported in this thesis is initiated to investigate these issues in Egypt, towards developing a framework for improving delay analysis and to identify the factors affecting the selection of a suitable delay analysis methodology from point of view of client, project management/consultant, and contractor. The methodology adopted in undertaking this research is the mixed method approach involving : first, a detailed review of the relevant literature, then an industry-wide survey on the use of these methodologies and the factors affect their selection, followed by another survey to develop model to assist and help analysts in choosing the appropriate methodology based on top five ranked factors and each delay analysis methodologies. The data collected was analyzed, with the aid of the statistical analysis tools. The key finding is that delay analysis methodologies reported in the literature having major weaknesses are the most widely used in practice mainly due to record keeping practice. To facilitate the use of more reliable methodologies, which ensure more successful claims resolution with fewer chances of disputes, a framework is developed comprising : (i) best practice recommendations for promoting better record and supporting documents keeping and ; (ii) a model for assisting analysts in their selection of appropriate delay analysis methodology based on the top five ranked effective factors. Finally, areas for further research are identified.
