Abstract
Completion time is an important criterion for determining construction project success. Many construction projects are
completed behind schedule as a result of various risks involved in construction projects. Performance of project
completion time can be improved if the risk factors that could cause delay are evaluated and managed. This study
assessed the impact of project risk factors on completion lime of construction projects. Data was collected using
structured questionnaires administered to 192 construction practitioners. 138 questionnaires were duly completed and
returned but only 114 (59.38%) were found fit for analysis. Descriptive statistics was used to analyse the data. The
study identijied financial difficulties of owner' (MS = 4.35), 'inadequate time estimate' (4.33), 'delay in progress
payment by owner/client' (4.23), 'poor labour productivity' (4.22), 'shortage of skilled labour' (4.18) and frequent
design changes' (4.05) to be the topmost risk/actors that impact on project completion time. The study concludes that
financial', 'design' and 'contract administration and project management' related factors group are those with high
impact on project completion time.
