Abstract
The Ashiyahama Housing Competition which included construction system as well as planning was carried out for the main purpose of the development of building techniques. This paper is intended to consider the purpose of the development and the problem which occured in the execution process. Every participator proposed its original superstructure system which aimed lightening, enlarging and standardization of the member of the frame-work considering the systems of the production and the transportation. Though the first prized proposal was put into practice on the whole, its planning was considerably modified by many reasons, one of which was the guidance by the goverment authorities and supplier considering safety and administration systems. Moreover, the construction systems was tolerably modified eventually. This showed the construction systems could be changed if the economical situation have changed. So the role of the expected contractor was important in technical development through the term of settlement of the working plans. By which, the proposed techniques were actualized and improved for the practical use. This type of condition for modification could highly occur in future projects which are aimed the development of techniques. Therefore, it is necessary to re-consider the situation of the construction systems in the proposal adding to the problem of the standard performance. Hereafter, We have to study the way in which both of the client and the contractor can make a certain profit by accelerating a technical development in construction terms as well as in planning terms.
