Abstract

It is common to encounter delays in construction projects. The consequences of these delays symbolize a substantial percentage of the overall project contract value. Delays might also cause trepidation among different project stakeholders, breed troubles in contractor's cash flow, and amplify owner losses. Therefore, the assessment of delays in construction projects should be an integral part of contract development. Current research identifies the main causes of delay; evaluates their effect on various construction projects; and classifies them according to four sectors: residential, building, heavy, and industrial construction. Four main causes of delay were identified: (1) acts of owner; (2) acts of contractor; (3) acts of owner' representative; and (4) unforeseen conditions. Data, related to the causes of delay and their effect on projects, were collected from construction practitioners in various industry sectors. The Analytic Hierarchy Process (AHP) was utilized to evaluate the causes of delay and prioritize them. Results show that delays in construction projects are mostly due to acts of owner (29.90%). However, industrial construction sector has the highest percentage of delays (42.20%).
