Abstract: | Factors that affect time overrun in the Nigerian construction industry have been studied, and the rank agreement factor for the professionals are architects∕engineers, 0.75; architects∕builders, 0.83; quantity surveyors∕engineers, 0.74; quantity surveyors∕builders, 0.79; and engineers∕builders, 0.69. Important findings are (1) the degree of occurrence of time overrun is high—between 80 and 90%; (2) relative contributions of the client, contractor, and others are 62, 32, and 6%, respectively; (3) time overrun is more pronounced in government/public sector projects (89%); and (4) time overrun occurs on all projects, irrespective of size. |
