Computer-Aided Planning, Design, Estimating and Scheduling of Earthwork

A computer-aided technique is being developed for planning, design, estimating, and scheduling of horizontal construction for facilities required to support military operations. This technique permits the user to quickly analyze possible sites and identify those which would require the least construction effort. Once the user selects the site for a facility, the system can design the earthwork, quantify estimates of each earthmoving function, and generate a construction schedule. The user can choose whether the schedule is to be equipment constrained or completion time constrained. This paper describes the technique, including discussions of site data acquisition, the procedures used for quantifying earthwork and estimating equipment productivity, and correlations of these with a required task sequence to generate a construction schedule.
