Improvement of a Computer Integrated and Automated Construction System for High-Rise Building and its Application for RC (Rail City) Yokohama Building

A variety of improvements have been added to the Shimizu Manufacturing system by Advanced Robotics Technology (SMART) developed by Shimizu Corporation based on evaluation of the results from the system's application in the construction of a building in Nagoya, Japan several years ago. The improved system was used this time in the construction of a building in Yokohama, which was not only larger than the Nagoya building but more complicated in design. In this paper, I compare the characteristics of the system application plan for the Yokohama project with the one in Nagoya. I describe the improvements, with particular emphasis on automation technology, discuss the procedures used in carrying out the construction, and examine the implementation results. Finally, I touch on directions of future developments.
