Research on Integration of Design and Construction by "Sogo-zu"

本研究旨在探讨崇光建筑的设计与施工一体化。首先对1995年学期的研究计划和研究的实际情况作了如下介绍。SOGO-ZU使用方法分析：通过对SOGO-ZU使用方法的实地调查，确定了SOGO-ZU的功能如下：(1)通过调整多个主合同的建筑工程的建筑图纸，在制作施工图之前，提高设计信息的一致性。(2)订购后，经常生成变更单。作为最终确认这一变化的工具的SOGO-U的功能。(3)SOGO-U的绘制过程与承包商对设计的足够了解有关。使施工阶段的问题清晰，提高了施工图的制作效率。(4)建筑设计是通过一定的信息交换，通过制作SOGO-ZU来实现的。这就减少了建筑师在施工阶段的管理力量。作为信息整合工具的SOGO-ZU真实情况。在国际上活跃着设计与施工一体化的研究领域。在日本，这种概念性的安排是落后的，因为日本存在着设计-建造实践的传统。可建造性和可施工性这一概念是在设计阶段以设计-建造合同的形式对施工的简易性进行评估的概念，在英美两国得到了广泛的应用。

This research aims for investigation of integrating design and construction by Sogo-zu. At first the research plan of 1995 term and the real situation of research are described as follows.1. Analysis of use method of the Sogo-zu : The function of the Sogo-zu was defined from the fact-finding survey of the use method of the Sogo-zu as follows.(1) The correspondence of design information are improved by adjusting architectural drawings of each construction work that multiple prime contract is done, preceding the shop drawings made.(2) After ordering, the change orders are frequently generated. The functions of the sogo-zu as a tool of a final confirmation of such a change.(3) The process of drawing of the Sogo-zu is connected with enough understanding of design for contractors. As a result, problems in construction stage are clear and the efficiency of making shop drawings is improved.(4) Architectural design is fixed at early time by a certain information exchange through making the Sogo-zu. So that decreases architect's management force under construction stage.2. Real situation of the Sogo-zu as the information integration tool. The research area where integration of design and construction is activated internationally. The conceptual arrangement is behind in Japan where the tradition of design-build practice existed. the concept named buildability and constructability to which the easiness of construction is evaluated with design stage as design-build contract gains in popularity in U.K.and U.S.A.The classification was done from the analysis of the making step of the Sogo-zu based on such a concept.
