Completion time is one of the yardsticks for measuring the level of project success in the construction industry. Thus, timely completion of construction projects is of great concern to construction projects participants. However, time overrun in building projects has been observed to be one of the major problems of the industry for many years. This paper examined the causes of time overrun in building projects with a view to attracting policy response which could enhance project time performance. Copies of structured questionnaire were administered on 95 construction professionals in contracting and consulting firms in Lagos State, Nigeria out of which 70 were properly filled and used for analysis. Mean score and Spearman’s rank correlation were used to analyse the data collected. The study indicates that both contractors and consultants were in agreement that time overrun was mostly due to financial difficulties, incomplete project details and clients’ interference.
