Purpose - The purpose of this study is to find out any potential factors for explanatory variables when calculating the virtual successful bid rate in case of no collusion. Design/methodology/approach - An empirical analysis was conducted in this study with a regression analysis that included 725 bid samples under the public construction technical type bidding. Findings - The result of the basic analysis showed that there are several factors affecting the successful bid rate. First, collusion variable; second, government variable; third, successful bidder design score variable and the number of bidder variable among bidding features; fourth, turnkey variable based on the alternative method; fifth, civil works variable and plant works variable based on building work; sixth, asset variable and the fourth-quarter performance difference variable. However, the technical proposal method variable among bidding features was found to be statistically insignificant in column(4). Research implications or Originality - The significance of this research is that new variable such as the government variable and the fourth-quarter performance difference variable were added in the regression model, which showed statistically significant research results.

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.

In the delivery systems for public construction works, design-build methods such as turn-key and alternative have contributed to improving the quality of structures and developing the construction technology. However, it is pointed out that construction based on a design-build method is likely to waste a budget due to its higher contract price than construction based on a design-bid-build method. Other issues such as contract monopoly, bid rigging and deliberation irregularity in design-build. Since there are not much works have been accomplished to comparatively analyze the actual performance and effect based on delivery methods, discussing and judging the performance and effect of each deliver method with limited information could lead to an error. Thus, this study by extensively investigates the actual project cost data, ranging from contract price to the construction cost of the public construction works and comparatively analyzed the characteristics of each delivery method about cost structure and fluctuation trend. This work is expected to assist stake-holders in properly understanding delivery systems for public construction works and promoting their efficient management.
