In this study, attempts to analyze the case study of production design were carried out through: 1) exploration of the factors influencing the interface between architectural and production design phases; 2)application of precast technologies. Building design and construction planning in Japan may be characterized by ample use of Production Design which extends over the whole projects phases. Taking a composite construction system for apartment buildings which allow for alternative combination of different technologies as a case study object, three projects have been chosen to analyze actual process of determining product sub-system and their specification. And the expectancies of this paper are that it can be used as efficient data for improvement of system to systematize Constructability(Buildability) in korea.

Achieving high productivity and constructability are very important issues in construction industry. Study on constructability have been conducted actively, and many researches referred that improving constructability can enhance cost, quality, schedule, productivity and so on. However, there are lack of quantitative analysis, since most studies have proved correlation between productivity and constructability using questionaries and by case studies. Also, researches are mostly about specific detail scope of work to improve constructability, thus it is hard to apply constructability factors on various work in construction. In this paper, will deduct general factors affecting on constructability and evaluate effects of factors affecting on each work. Furthermore this paper will verify impact of factors affecting on productivity by multi regression anlaysis using actual data sets of high-rise building construction site.
