Abstract
This paper presents the study on some productivity in the Ashiyahama housing complex construction in order to contribute design and constrnction planning for long term and large scale projects with industrialized construction methods. The study was produced with collecting and analyzing daily site reports and time lapse research. As a result of this study, the learning effect and differences in capacity of a work team were found both in the super structure construction and in the interior finish works. In addition, it was recognized that man hour planning and outside order planning based on learning effect are useful in the super structure constructions. Meanwhile, it was realized that efficiency in the interion finish works depends on crew's experience, which resulted in that skill training as will as effective constitution of work teams is significant. Consequently the formula to predict man hour was defined to grasp many factors which influence man hour in works. Also selection and layout of cranes in connection with flat layout and component design have proven useful.
