Abstract
This paper proposes a new method for construction supporting system, purpose for“information sharing and cooperation” and “improvement of operating processes” in the construction field. Web3D technology helps field supervisions in construction with interactive and intuitive display. Utilization of information, progress control of working form support system using 3D-CAD and TS has. First, sort out problems in exciting supervision and inspection of works and set system requirements. Second, build and propose of systems to meet the requirements. Finally, verify effectiveness of systems in actual road works and consider the results of demonstrational experiments.
