The Development and Application of an Automatic Building Construction System Using Push-Up Machines

The "AMURAD" system developed by Kajima Corporation is so-called "building factory". The first to fourth floors function as a factory where low level construction work is performed utilizing integrated construction information. When one floor is completed, it is pushed up by special computer-controlled jacks. The first application of this system was at a condominium construction project in Nagoya implemented by Kajima Corporation.

This paper gives an outline of the AMURAD system and describes the results of its application.
