Abstract: An investigation into current earthworks planning practice showed that the planning techniques used tend to be subjective and time consuming with a heavy reliance given to the experience and knowledge of the planner. This practice can lead to inaccurate planning and makes explanation of the techniques used difficult. In this paper, an approach to automate the earthworks planning process is described and the basic techniques that are used are outlined. A computer-based system has been developed to help planners use existing techniques more efficiently. With their input the system has been extended to incorporate a knowledge base and a simulation of the earthworks processes. As well as creating activity sets in a much shorter time, the system has shown that for a real project the model is able to generate activity sets that are comparable to those generated by a project planner.
