Integrating barcode and GIS for monitoring construction progress

This study focuses on developing an automated schedule monitoring system for precast building construction. Erection of prefabricated structural components is the major critical activity for precast building construction. An efficient lifting schedule and control plan can significantly reduce construction conflicts and project delay. In this research, the system ArcSched was developed to assist engineers in controlling and monitoring the erection process in a real time basis. ArcSched is composed of a Geographic Information System (GIS) integrated with a database management system. Through systematic monitoring of the construction process and representation of the erection progress in graphics and colors, the scheduled components for erection are repetitively tracked and well controlled to implement the lifting schedule as planned.
