A Management System for Cut and Fill Earthworks Based on 4D CAD andEVMS

摘要

A cut and fill earthworks management system was developed based on 4D CAD andrnearned value method. The system is composed of a schedule management system, 4DrnCAD system, cost estimation system, and earned value management system (EVMS).rnLandXML was employed as the product model to represent terrain data, and IFC wasrnused to represent the process model. We applied the system to a past actualrnearthworks project and demonstrated that it could facilitate enhancing the control andrnmanagement of cost and schedule of construction works as well as incorporating thernprogress payment method effectively.
