Automated Construction System for High-Rise Reinforced Concrete Buildings

The all-weather automated construction system has been developed to reduce the total cost of high-rise reinforced concrete building construction, and was applied to a 26-story reinforced concrete condominium project located in Chib a prefecture in 1995 for the first time in the world. This automated construction system consists of four major technologies: a) Synchronously climbing all- weather temporary roof; b) Parallel material delivery system with one construction lift and three overhead cranes carrying three transfer hoists; c) Prefabrication and unification of construction materials; and d) Material management system using database system linking with CAD. Consequently this automated system is effective when used at the site. It ensures good quality, improves the working and environmental conditions, reduces the construction period, manpower, and wastes, and improves overall productivity.
