Management of a construction project is challenging due to the unique nature of each project. Even though the project itself is unique, the activities within it are generally repetitive. Network techniques which were developed for overall management of projects are not appropriate for detailed planning as they are highly abstract representation of the actual project activities. Simulation has the potential to be used for detailed planning as it permits the modelling of cyclic activities and uncertainties, such as, variations in duration and occurrences of probabilistic events, such as, equipment breakdown. The objective of this study is to investigate the application of discrete event simulation as a tool for detailed planning of repetitive construction processes. As a part of the investigation, CPM and simulation models representing the girder casting and placing activities a of bridge construction project was developed. Two alternate construction processes were modelled using the techniques. The models were tested by varying the resource levels and factors, such as, duration of project. Utilization of key resources were assessed. The results obtained are presented and discussed. It was found that the simulation is a useful tool for detailed planning of repetitive construction activities.
