The purpose of this study is to present both problems and improvement plans on the bidding system of the Korea National Housing Corporation, which orders apartment houses professionally. For data gathering, this study used data from electronic procurement system from 2001 to 2005. The research method of this study is to analyze the data categorized into four types: changes of ordering and contract price ration, the lowest-pricing bidding system, and permanent projects by grades. As a result of the analysis, the amount of ordering is biased in favor of particular level. Finally, this study present following improvement plans: 1) screening system and the lowest-pricing bidding system need to be supplemented, 2) the contract price ratio and the amount of ordering should be controlled, and 3) the improvement of PQ and the introduction of the list of Qualified companies by types need to be presented.

입낙찰제도의 효율적 운영은 건설산업의 발전과 산업구조 선진화를 위한 정부 정책의지 실현에 있어 핵심적인 요소가 된다. 본고에서는 현행 입낙찰제도 중 가장 큰 논란이 되고 있는 최저가낙찰제도를 대상으로 그 시행성과와 실태를 짚어보고, 그 개선방향과 효율적 운영방안을 제시하였다. 실태분석 결과, 현행 최저가낙찰제도의 핵심적인 문제는 지나친 저가낙찰로 인한 건설업체의 수익성 악화와 부실공사의 우려이며, 이는 건설업계의 차원을 넘어 국가와 공공의 이익에 있어서도 위험요소로 적용할 가능성이 크다. 그러나 건설산업의 선진화 관점에서 볼 때, 최저가낙찰제라는 제도 자체는 많은 긍정적인 가능성을 가지고 있는 제도이다. 따라서, 최저가낙찰제가 정착되기 위해서는 단기적으로는 실효성 있는 저가낙찰 방지대책의 조속한 수렵이 필요하며, 장기적으로는 최저가낙찰제가 제 기능을 발휘할 수 있도록 보증제도 개선, 발주자의 역량 강화 등 건설산업 전반에 걸친 제반 여건들을 정비해 나가야 할 것이다.

Korean engineering firms need to improve their performance in order to stay competitive in the globalize environments which has been led by some international movements including World Trade Organization (WTO) and Free Trade Agreements (FTA). There have been various activities and researches focusing on how to improve competitiveness of Korean engineering firms and the out-of-fashion Engineering Project Delivery System (EPDS) has repetitively identified as one of main barriers to deter advancements of Korean engineering industry. Therefore, this research attempted to investigate global standards of EPDS such as International Federation of Consulting Engineers (FIDIC), American Federal Acquisition Regulations (FAR), Brooks Act, and so on. The procedures of international EPDSs along with a few case studies were comprehensively analyzed and compared with Korean EPDS in order to propose recommendations of improving Korean EPDS. Some major differences between international and Korean EPDS were identified and they includes emphasis on qualifications of engineers and/or firms rather than their proposed cost, extensive use of long and short-list, common use of negotiation process, etc. Research findings are envisioned to guide the Korean public engineering sector to innovate Korean EPDS.

Our country's bidding system had made the lowest price successful bid system in foundation before introducing eligibility review system at July, 1995, and a averaged- price successful bid system or the restrictive-lowest price successful bid system had been enforced by repletion. However, they were introduced as dumping that do not reach in direct cost level of construction cost is generalized and worry about illegal construction practices rises by the lowest price successful bid system. According as they had not been promoted construction company's technical development effort or cost reduction effort, vicious circle that advocate competition principle again and recur as the lowest price successful bid system is repeated last 50 years. Therefore, I present improvement direction that can satisfy all Global Standard and real condition of our country through foreign countries example analysis to cope with the rapidly changing building circumstances socially and economically to correspond actively to the construction industry's reorganization to reconsider domestic construction engineering's competitive power.

International construction market has been depressed significantly after 2000. Exclusive techniques and advanced construction management methods are desperately in demand so as to ensure the competitiveness in unlimited competition. Although public construction delivery system has been revised several times starting with introduction of the lowest bidding system in 1951, there has been no remarkable achievement whenever new system was introduced. This study analyzed the successful stories of developed countries like Europe, USA and Japan to settle successful rating system down and vitalize the best value system in Korea, which was introduced in October 2007. We constructed the bidder evaluation system for domestic situation, and designed the evaluation tool which is useful in utilization. Since this study were analyzed on only same systems of developed countries and domestic similar cases, this study is limited to typical construction in Korea. The study of specialized rating system in the field related should be followed.

Domestric Construction & Engineering market has been long in recession due to the global economic crisis. Domestic construction industries consequently looks at overseas construction markets where relatively more construction projects are constantly required. In order to provide meaningful information for Korean engineering companies to keep the pace with the changes in the construction industry, various construction related date and statistics are analyzed. In addition, previous research from the related organizations and construction engineering companies are closely reviewed. Investigation of preliminary data and research have been conducted to draw remedies for their overseas expansion. Moreover, it is attempted to classify foreign markets as the Asia, Africa and etc. (Europe, North America/the Pacific and Latin America) to provide the list of first target countries and its regional market information focusing on their bidding system. This study had tried to show comparative analysis of different bidding procedures between Korea and the selected countries to suggest measures of improvements for the domestic bidding system. Finally, this study suggested policy recommendations to meet the requirement of bid qualification to advance the global market that was suggested with validated clustering bidding data.

The Domestic Construction Industry is in the process of changing from a one-sided production method centered on the contractor to a production method in which the order and the contractor can collaborate. Depending on the delivery method, the bid/success method, the contract method, and the degree of business involvement of the order may also vary. In this thesis, in order to introduce 'Construction Management at Risk' suitable for the domestic environment, domestic and foreign institutional analysis, bid process analysis, contract fulfillment and management analysis, post management analysis, and related laws and regulations for legalization In order to suggest a plan for the efficient operation of the system, a system and case analysis of domestic and international construction responsibility type construction project management was conducted. 'Construction Responsible Construction Project Management' defined in the Framework Act on the Construction Industry is divided into the main contract transfer contract, which is a service contract performing pre-con work, and the main contract, which is construction project management and construction contract. Therefore 'Construction Management at Risk' should be regarded as one of the ordering methods rather than a successful bid system, as in the case of overseas, and legalization as a bidding system equivalent to design/construction batch bid and technology proposal is necessary for introduction. In order to introduce 'Construction Management at Risk' suitable for the domestic environment, domestic and foreign institutional analysis, bidding process analysis, contract fulfillment and management analysis, and follow-up management analysis are conducted. A method for efficient operation was suggested so that it can be applied in the domestic market while maintaining the original merits of this system.

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.
