Simplification of Concrete Structure Shape and Utilization of Precast Concrete for Robotization

"With an aim of automating and streamlining construction work as well as securing safety, the Ministry of Construction has been striving from 1990 to 1994, for the accomplishment of a general technology development project, 'Development of new construction process technology' that covered an extensive field of construction. The primary objective of the project was to develop new construction equipment and technology that enable the automation of construction work and laborsaving. The project was also aimedto develop new design and construction methods that facilitate the automation of concrete structure construction work through the simplification of concrete structure shapes, pre-assembling of reinforcement (bars are prefabricated in units in specialized factories) and the development of a large-scale structure prefabrication method. This paper reports the results of the study efforts. "
