From 2010 years to 2013, the selection method of successful bidder has been changed design suitable lowest method, comprehensive evaluation method(bid price adjustment, design score adjustments, weight standards), fixed amount best design method. Therefore this study was presented by analyzing the impact on the domestic construction industry according the way to determine the successful bidder, the evaluation order method and the operational issues through the analysis of order status, order number, results of acceptance an order, success rate range, results of acceptance an order according to weight success rate, results of acceptance an order by work type and order institution of a turnkey alternative tendering construction performed in domestic civil part.

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.

Full system of turnkey deliberation committee in 2010 was abolished and permanent Deliberation committee was introduced. So far, ordering organization selected the best method suitable for the design and comprehensive evaluation method in the turnkey bid construction. Comprehensive evaluation method have bid price design score coordination, weighted basis, the best design approach fixed amount, five successful bidder decision method in addition. Design deliberation branch committee in the successful bidder decision way configured and operated branch members of special design consultation committee, But main agent changed from committee deliberation pull system to permanent committee deliberation, as well as and The lobby burden was not improved. This similar to the past at the portion of the design deliberation and the way of the design deliberation in the turnkey bid construction. Therefore it is necessary to improve the design deliberation system. In other words, design score and technology competition should be adapted to determine a successful bid. This study suggested the operating system of the design deliberation, the decision method problems of the successful bidder and ways to improve the design deliberation.

300억원 이상의 국가 및 공공기관 발주공사에 대해 최저가낙찰제를 대신하여 종합심사낙찰제 전면 실시 등의 내용을 담은 국가계약법 시행령이 개정되어 2016년 1월 1일부터 시행에 들어갔다. 종합심사낙찰제는 가격 뿐만 아니라 공사수행능력, 사회적책임을 종합 평가하여 낙찰자를 선정하는 제도로 기존의 최저가낙찰제에서 발생한 덤핑낙찰 및 이로 인한 잦은 계약변경, 부실시공, 저가하도급, 임금체불, 산업재해 증가 등의 문제점을 해소하기 위해 도입된 제도이다. 종합심사낙찰제 도입에 따라 공사 품질이 제고됨으로써 생애주기(lifecycle, 유지보수비용 등을 포함) 측면에서의 재정효율성 제고를 비롯하여 불공정 하도급 관행 개선 등 건설산업의 생태계 개선과 함께 시공결과에 책임짐으로써 기술경쟁 촉진 등 건설산업의 경쟁력 강화 효과도 기대된다. 또한 국가계약예규도 개정되어 주계약자관리방식에 의한 공동계약(주계약자 공동도급)이 최저가낙찰제에서 종합심사낙찰제로 전환됐다.

Design-Build, one contractor is responsible for both the design and construction, has become more popular since the government framed the policy on how to activate the design-build projects in 1996. The reality is, however, there are many problems encounted on Contractor Selection Method for Public Design-Build Projects. The purpose of this paper is to improve the problems, no way to meet the goal(value) the owners expect from the design-build projects, for instance, not fully reflecting the characteristics of projects and owners intention, not systematical enough to judge if bidders could carry out the contract. This study will insist we introduce Best Value Procurement, which is being commonly used in some advanced countries recently, so that we would properly select the contractor suitable for Best Value concept which totally depends on the owners, types of work and specified conditions. Furthermore, by passing through the Two-Step Procedures following Pre-qualification in Best Value Procurement, we expect it lighten the bidders' burden for proposal and the owners' complicate bid administration.

Design-build that a single entity performs whole construction process under singular responsibility is one of the project delivery system comes to take expectation effects of time savings, cost saving, and quality assurance. On the other hand, a current domestic method for selecting a design-build contractor is difficult to reflect the purpose of owner and the project characteristics when owner selects the design-build contractor. The purpose of this research is to suggest a model for deciding evaluation weights in design-build which can reflect the purpose of owner and the project characteristics. This research can help owner to select the best suitable design-build contractor for the project.

Recently the Ministry of Finance and Economy of Korea launched two new project delivery systems called "Best Value Contract (Design-Bid-Build)" and "Bridging Contract (Design-Build)" in October of 2007 by revising enforcement ordinances of "Act on Contracts to Which the State is a Party". These project delivery systems require the bidders to submit technical proposal adjusted to the project characteristics and objectives for selecting the contractor by evaluating technical proposals. This research aimed to suggest guideline to effectively operate the project delivery systems described above. To reach the goal of the research, the framework of the operation model was developed, which includes the four categories: the standard bidding process, the technical proposal requirements, the technical proposal evaluation criteria, and the award methods. The contents of the four categories above were fulfilled throughout conferring with the advisory experts. In particular, the award methods, which are the important decision-making factor in the perspective of the owner, consist of four types: Low Bid-Fully Qualified, Weighted Criteria, Adjusted Bid, and Adjusted Score. The quantitative features and application criteria of these four types of award methods were suggested throughout the simulation using the virtual case.

A construction project consists of many types of contracts. In the process of selecting the successful contractor after bidding, there will inevitably be fierce competition, which may lead to corruption or bribery. Even after signing the contract, during the period of settling the amount of the contract, bribery could occur. Such corruption could harm the development of the construction industry. It is, therefore, necessary to establish a strategy to prevent corruption by strengthening the transparency of the bidding process. In this study, to prevent corruption in the construction industry, a new service is proposed in which the successful bidder is selected by a professional third party, and the introduction of diverse delivery systems for construction projects and the invigoration of alternative methods of settling disputes are also proposed in this study.

In bidding processes conducted by government agencies, local governments or public agencies, budget prices are critical to both ordering bodies and bidders since budget prices are bases for selecting a successful bidder. Since a high budget price goes against ordering bodies and a low one goes against bidders, most ordering bodies adopt a system using multiple preliminary prices for determining a budget price to ensure fair and transparent manners. Discussed are how budget prices change depending on the methods of sampling 15 preliminary prices and the methods of sampling 4 out of 15 prices. Computer simulation is conducted to analyze budget prices for various methods to determine multiple preliminary prices. It is more likely for budget prices to be close to base prices when splitting a range of generating preliminary prices into 15 intervals and taking 4 preliminary prices from 15 intervals than when taking 4 preliminary prices from a whole range. In cases when splitting a range of generating preliminary prices, if we take 2 preliminary prices out of intervals above 100% and take 2 out of intervals below 100%, the expected budget prices are equal to a base price and the standard deviations are about half in comparison with those when taking 4 out of 15 intervals.
