사물인터넷 기반 건설 프로젝트 성과측정원형 개발

Conventional progress control technique which collects and manages construction progress data manually is involved in inaccurate and omitted information in construction phase. It is time consuming and labor intensive to acquire the construction operation data in detail. It is important to develop the system that analyzes the project performance accurately and control the progress efficiently by keeping track of the progress data at a lower level than the operation. This paper proposes a system prototype which measures project progress at the construction operation level by hybridizing remote-controlled robots (i.e., air-drone and wheel mounted vehicle), smart sensors, and project scheduling and controlling tool. The system is developed into an Internet of Thing(IoT)-based progress measurement system. using robot and information technology. Earned value method-based physical progress measurement method is utilized to compute the quantity of work completed. A test case was performed to confirm that the new system complements the limitation of existing progress control method.
