Abstract

The degree of uncertainty which surrounds the accuracy of a schedule in construction is one of the key factors which extends the expected finish dates on many construction projects. This paper describes a process that enables a systematic assessment of schedule uncertainty to be made using four dimensions of schedule uncertainty. The evaluation of a knowledge base of schedule related risks is described. A Hypercard application program provides an information module which is used so that schedule risks can be identified. A spreadsheet is used to model schedule risk and determine the expected project completion date, the importance of each risk, and other knowledge and statistical data. 1 Introdu
