Abstract
Time performance of a project is usually a particularly important consideration for the construction parties. Often, the most troublesome construction disputes involve delay and failure to complete the work within the specified time frame. This study aims at identifying the risk matrix for delay causes in building construction projects in Saudi Arabia from contractors' viewpoint. A questionnaire survey was undertaken of 35 contractors working on construction projects in Saudi Arabia. 20 delay causes were identified through literature review. The study concluded that the top delay causes in building projects from contractors' perspective are: Bid award for the lowest price, fluctuation of prices of materials, frequent changes in design, payments delay, poor labor productivity, rework, and lack of adequate manpower.
