정부는 지난 8월 11일 건설분야 기업환경 개선대책을 확정 발표했다. 정부가 발표한 '건설업 기업환경 개선대책'에 따르면 앞으로 최저가낙찰제 공사의 덤핑입찰을 차단하기 위해 노무비와 품질 안전 환경 등의 공종에 대한 저가심의가 한층 강화되고, 하도급대금 지급 확인제도를 모든 공사에 확대 적용하며, 주 계약자 공동도급제도도 개선한다. 또한 중소 지역업체의 경영환경 개선을 위해 건설공사 도급하한액을 상향 조정하고 입찰참가자격 사전심사 시 지역업체 시공참여 배점제를 도입한다.

우루과이라운드 협상에서 건설시장개방은 건설서비스로서 일반시장개방과 정부조달과 관련된 공공건설발주시장개방의 두 측면에서 이루어졌다. 정부는 건설시장과 함께 국내 건설관련 제도들을 계속해서 개선해 오고 있다. 제도 개선의 초점은 입찰, 면허제도 등과 같이 외국업체에 대한 영업자격부여방안이며 그밖에 감리제도 등도 부실공사방지대책과 맞물려 개선이 이루어지고 있다.

This paper considers the effect of various types of procurement auction system on competition focusing on the rate of successful bidding. We analyze the number of bidders and the rate of successful bids using online procurement data of the Public Procurement Service. The average number of bidders is 301 and the average rate of successful bids is 87.42% while the weighted average rate is 75.13%. These numbers show that there is quite strong competition among bidders and the rate is lower as the expected price is higher. When we analyze the data of price procurement auction, the rate is also shown to be lower as the expected price is higher. Furthermore, the rate decreases as the number of bidders increases which naturally makes the competition stronger. Meanwhile, the analysis finds that the inclusion of the onsite bidding, the PQ(Pre-Qualification) result, or major-10 winning companies cannot explain the rate much in our data. In case of turnkey-alternative, the average rate of successful bidding for 484 cases record 90.20%. The average is 84.89% with 120 alternatives and 91.97% with 364 cases of turnkey. The reason why the rate of turnkey-alternative is lower than that of price procurement auction is the lack of competition as well as the systematic difference. By setting up a model, we are able to explain the difference in rate caused by the respective reason. When we suppose there are 3 bidders in case of price procurement auction for a project that exceeds 100 billion won, the rate is expected to be around 64%. This implies that difference of 26% is caused by the systemic difference and 3% by the lack of competition. Therefore, we conclude that the difference in rate between turnkey-alternative and price procurement auction is caused mainly by the systemic difference. In case of PPP(Public Private Partnership) projects, among 154 projects in total, only 40% has more than 2 bidders that compete. The average number of bidders is 1.88 which is less than 2, and the average rate of successful bids is 90%. In sum, under the price procurement auction, there is strong competition which is reflected by the rate of successful bids. However, there is room to decrease the rate by strengthening the competition under the turnkey-alternative. Also with PPP projects, we expect the rate can be steadily reduced with revived competition among bidders.

The government intensifies screening criteria for the guarantee of reasonable bidding price and the prevention of low bidding price, however, the low tender rate still becomes an issue. This study analyzed the problems of screening criteria for the guarantee of reasonable bidding price, and then derived some major issues such as the restriction of decisive factors for initial construction cost, the rate of activities over five percent of surveyed price and the restrictive review criteria of inadequate activities. To solve thess problems, this study suggests an improved process model for estimating optimal bidding rate that can select a contractor with the guarantee of reasonable bidding price.

Inspection system which was performed in the past selected the final winning bidder by separating Pre-Qualification, the basic design evaluation and price evaluation. However, turnkey and alternative bidding construction has selected way to determine the successful bidder as the best design and the most low cost method, comprehensive evaluation method (bid price adjustment, design score adjustments, weights standard), the best design and the fixed amount method from january 1, 2010 to the present. Due to these institutional problems, orders institutions were often a way to determine the successful bidder to apply differently for identical or similar construction. Therefore this study winning bidder selection criteria through analysis of construction the number and construction order performance, order performance by work division and institutional orders, the weights bidder order performance and orders status of turnkey alternative tendering construction to civil part performed in domestic.
