摘要：Time schedule is an essential tool for construction project management. For instance, it can materially help to identify the expected financial requirements. It is also an important tool for the time control process. Construction project time schedule is greatly affected by many uncertain but predictable factors. Hence, a certain percentage of time contingency should be added to the scheduled time to arrive at more reliable time schedule. In this research, the most important factors affecting time contingency in construction projects were identified based on a comprehensive survey among a collected sample of the Egyptian construction experts. In addition, a neural networks model was developed in order to help project planner to have a more reliable prediction for the amount of time contingency that should be added to the scheduled completion time. This paper explains the data collection process, lists the main factors affecting time contingency and discusses the model development methodology.
