document: Planning linear construction projects : automated method for the generation of earthwork activities Earthworks planning for road construction projects is a complex operation and the planning rules used are usually intuitive and not well defined . 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 , initially 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
