  • Publication number: 20130290054
    Abstract: The present invention relates to a method of measuring progress of a construction work process using a motion sensor. A reception unit of a management server receives data about expected engaged workers for different processes, for different days, and for different floors. A control unit of the management server arranges the received data into DBs in such a way as to store the data about the expected engaged workers for different processes, for different days, and for different floors in a process-based engaged worker DB, a day-based engaged worker DB, and a floor-based engaged worker DB of a DB unit, respectively. The control unit creates an expected work schedule using the stored data. A communication unit of the management server receives data actually collected via the motion sensor. The control unit measures progress of work by comparing the actually collected data with the expected work schedule.
