CONCEPTUAL DESIGN USING BIM OF ULTRA-HIGH-SPEED CONSTRUCTION SYSTEM ASSUMING EMERGENCY SITUATIONS

Abstract

The Japanese construction production system has aimed to achieve a high degree of balance between high Q: quality, low C: cost, appropriate construction D: duration, S: safety assurance, and reduction of E: environmental impact in project results. Against the background of low economic growth and low interest rates after the bursting of the bubble economy, the Japanese client did not strongly demand "UHSCS: ultra-high-speed construction system," which is the purpose of this research theme. However, if the QCSE satisfies the required standard, it is obvious that the introduction of UHSCS that realizes early recovery of funds will increase the value of the project. In addition, it goes without saying that reducing time, which is a parameter for amount of labor, material, and indirect costs, is effective in improving productivity, which the Japanese construction industry is currently working on. During the recent spread of COVID-19, those of us involved in construction watched helplessly as lives and health were lost due to the lack of medical facilities. In Wuhan city, China, a medical facility with 1,000 beds is said to have started operating 10 days after the site was prepared. In China, which is undergoing economic growth and has high financing costs, there was a strong need for UHSCS for hotels and offices. Based on the current situation, it is necessary to review UHSCS as another form of building production. The international architectural society has a social mission to prepare for the occurrence of similar pandemics and disasters such as earthquakes directly hitting the Tokyo metropolitan area that are predicted to occur in the future. This research utilizes the excellent construction elemental technology of Japanese industry, BIM, IoT, SCM and robotics, and presents a conceptual design of an UHSCS based on thorough standardization and labor-saving construction.
