Integrating barcode and GIS for monitoring construction progress

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