This article is about the study on construction contractors in Daegu during the Japanese Colonial Rule. The first construction contractors who involved with Kyong-bu railroad work in 1904 personally. But, after they go through the bidding method, changed by the Japanese Government General of Korea in 1922, and the second bid rigging in 1932, contractors was changed gradually the organization into unlimited partnership, limited partnership or stock corporation. The number of them was increased. Most contractors were Japanese, and organized a limited partnership which has been capitalized at 30,000 won. On the other hand, Korean contractors couldn't work at an important part, except for the personal activities of Youngsil Lee(李永實). They were usually employed as consultants or field deputies by Japanese contractors. After the Liberation, Japanese construction contractors returned to Japan, however Tatuoka-kumi(龍岡組), Yasiro-kumi(屋代組) and Sakano-kumi(坂野組) that was leading the business which were took over by Koreans. They were leading architecture field in Daegu.

Most of specifications are composed by letters and the contents of specifications are very bulky. There exists correlation between the detailed contents. Therefore, to be achieved suitable quality of electricity function; it requires effectively organized and well expressed structured system. Therefore, it should be considered that assuring user's safety and guarantee capability of electricity installation through development of making such systematic specifications and supply of a technology that heighten consummative technology. Because the scope of electricity construction that requires making specification is very wide, in order to save resources and improve the level of technology, it is required that the standard of technology that is composed in the electricity construction that is from unit of electricity construction to whole electricity construction should be united and controlled nationally.

Little attention has been focussed on a precise definition and evaluation mechanism for project management risk specifically related to contractors. When bidding, contractors traditionally price risks using unsystematic approaches. The high business failure rate our industry records may indicate that the current unsystematic mechanisms contractors use for building up contingencies may be inadequate. The reluctance of some contractors to include a price for risk in their tenders when bidding for work competitively may also not be a useful approach. Here, instead, we first define the meaning of contractor contingency, and then we develop a facile quantitative technique that contractors can use to estimate a price for project risk. This model will help contractors analyse their exposure to project risks; and also help them express the risk in monetary terms for management action. When bidding for work, they can decide how to allocate contingencies strategically in a way that balances risk and reward.

In Japan, it has been argued between architects and contractors that which process is desirable, the traditional process or the design-build process. It is called the contractor-designer issue. In 1968, Kajima Corporation chairman Morinosuke Kajima and the Japan Architects Association had a public controversy over it. On the other hand, in practice, architects and contractors have secured quality of buildings thorough a close communication in the design and construction process of building. What are the relationships between architects and contractors? What roles do architects and contractors have in practice? This study has two aims. First one is to analyze the contractor-designer issue based on roles and relationships between architects and contractors, and then to show conflicts between them. Second one is to consider issues which architects face in the relationships with contractors.
