  • Turnkey and alternative-design contracts was introduced operation in the country from january 2004 to February 2010. this was introduced operation. The selecting method of contractor for turnkey projects has being operated by an open forum type that consists of technical committee and appraisal committee in an integrated design approach deliberations. But to improve the operation of the problems, the government is operating design review committee consisting of the central, local and special design advisory committee in march 2010. But this system has also been suggested as still problems, too many contracts by large companies, increasing of design cost and excessive competition. This study is intended to contribute that turnkey and alternative-design contracts can be well operated in domestic construction markets. In this paper suggests some improvement methods and operational problems caused from application of an open forum type for selecting contractor of turnkey project.

  • Design-build, which is defined as single source responsibility for design and construction, has been widely used in large public works since governmental formulation of measure for encouraging use of design-build in 1996. However, civic groups and small and medium sized enterprises are highlighting over-competition and unbalanced market shares of conglomerate in domestic design-bid market and insisting on decrease in the use of design-build and absorption into the lowest-price bidding. This study collected information about cost, schedule, quality, new technology adoption from 51 civil design-build projects and measured their performance.

  • Turnkey contract system is an effective ordering system for the ordering organizations that technical engineers are insufficient for their construction projects. It is possible to reduce project duration and to improve project quality in an integrated contract system between design and construction. However, owners can have a difficulty caused from unitary responsibility system. This study analyzes present situation and problems of turnkey contract system including railway projects. The result includes various methods for improving the system based on the analysis of bid price and selection procedure.

  • 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.

  • 단체수의계약은 중소기업의 경쟁력을 강화하는 기능을 갖고 있는 반면, 생산업체들은 경쟁을 하지 않고 일정 수준의 물량을 확보할 수 있기 때문에 중소기업들이 품질향상과 기술개발 노력을 등한시하는 요인으로 작용하기도 한다. 따라서 동 제도의 점진적인 축소에 이어 폐지시에는 그 대안으로 제한경쟁 및 지명경쟁 입찰자격 증명과 계약담당 공무원이 실시하는 이행능력평가를 협동조합이 담당하는 입찰자격증명 및 이행능력평가제도 도입도 검토해 볼 필요가 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.

  • 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.

  • Currently, the unit price of public construction projects are not being evaluated appropriately for several reasons. First, the evaluation of the unit price differ per nature of the bidding process and its estimation process. In fact, pricing is determined to meet the total price in turnkey projects and to pass the low bid price deliberation process in unit price projects, and thus, such prices cannot be said to be reasonable prices per public project. After the contract is awarded, however, the prices determined without taking into consideration the characteristic of each bidding process and price estimate process are used for the valuation of progress payment, design changes, and escalation. Furthermore, this is also being applied to other low bid deliberation process as actual public project unit price, thereby affecting other processes as well. In effect, this system increases the risks for both the owner and the bidder who have determined the unit price. This research examines the risk factor and its extent in order to properly manage it in preparation for the future.
