Consultants’ Perceptions on Construction Delay Analysis Methodologies

Resolving the delay claims that usually trail delayed completion of construction projects is beset with immense difficulties that often lead to disputes between the parties involved. The research reported in this paper is a part of a wider study aimed at developing a framework for reducing the attendant disputes and aiding cost-efficient dispute resolution. The focus of the part reported here is owner consultants’ perceptions on existing methodologies for analyzing project delay. Based on a survey of U.K. construction consulting organizations, the study examined, among others, the awareness and use of these methodologies, their perceived reliability, expert involvement, and obstacles to their use. The main study findings are: (i) delay analysis is a multidisciplinary task, with the project quantity surveyor often playing the leading role on the owner’s side; (ii) the simpler methodologies are used more often than the complex ones although the former are known to be less reliable than the latter; and (iii) the principal obstacles to the use of the sophisticated methodologies are: lack of adequate project information, the use of programmes not in CPM network form, and poorly updated programmes. It is thus argued that improvement in current programming and record-keeping practices will promote the use of the more reliable methodologies which, in turn, will facilitate smoother resolution of delay claims.
