Faced by a need to overcome work force shortage and vanishing skill replacement, a semi-automatic lift-up system of pre-assembled roof floor is developed by Hazama Corporation, which is one of general contractors in Japan. The semi-automatic lift-up system is able to automatically lift the pre-assembled roof floor up along with the progress of building frame construction. In addition, a monitor and warning computerized system is developed to monitor how the automatic lift-up system is working and the existing state of the pre-assembled roof floor, and to warn operators of the need of their intervention. As a testbed, these systems are applied to construct four stories steel structure building at the field of Technical Research Institute, Hazama Corporation. This testbed shows the constructability, operability and reliability of the systems when applying to an actual work site. This paper report the monitor and warning computerized system and its field evaluation and remarks.
