It is crucial In decision making to select a project delivery system (PDS) adjusted accordingly to the project characteristics. Furthermore, selecting a tendering system is the kernel in the process of selecting PDS. In October 2007, the Ministry of Finance and the Economy of Korea launched two new project delivery systems, "Best Value Contract (Design-Bid-Build)" and "Bridging Contracts (Design-Build)" by revising enforcement ordinances of "Act on Contracts to Which the State is a Party" to provoke the tendering systems. In order to support the proposed purpose, this research developed a selection model for suitable tendering system, which helps a public owner select a tendering system appropriate to the project characteristics. First, the framework of the model was set throughout analyzing previous researches and interviewing relevant experts. Additionally, by analyzing the survey result from 265 experts engaged in architectural and civil engineering business, the relative weights of the selection factors and the effectiveness values of the alternatives were suggested as the quantitative evaluation references. Finally, the practical guideline was suggested to apply this model to three public projects scheduled to be delivered. The result of applying the model to three case projects showed that further researches were needed to make the selection process logical and to suggest the standard weights and effectiveness values according to project type.

기술의 발전과 사용자환경의 변화는 지도에 대한 의식의 변화와 요구사항을 증가시켰다. 이러한 변화로 지도의 최신성 유지에 대한 중요성이 강조되었으며 수시갱신에 대한 방법들에 대한 다양한 연구가 진행되고 있다. 일반적으로 고해상도의 위성영상 및 항공영상을 활용하는 방법의 연구가 활발히 진행되고 있으며 건설도면을 활용하는 방안에 대해서도 연구가 진행중이다. 이러한 방법은 상대적으로 비용이 많이 소요되므로 이러한 단점을 극복하기 위한 대안을 제시하고자 하였다. 본 연구에서는 효율적인 지도의 갱신을 위해 나라장터의 입찰정보를 분석하고 공간정보 데이터와 연계가 가능하도록 시스템을 구축하였다. 입찰정보로부터 지형지물의 변화를 발생시키는 공사를 분류하고 데이터베이스화하여 변화예측 정보로 활용하였다.

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.

Design VE system in order to promote the economical efficiency and the functional elevation of construction facilities apply to conatruction over 10 billion from december 2005. But it don't achieve purpose of VE original to maximization of value creation through VE because VE perform formal and result center. This study suggests some idea and analyse implementation of design VE through design VE case of turnkey and alternative project performed in domestic.

The purpose of this study is to propose a rational and scientific damage calculation model in relation to damages caused by bid rigging in construction projects. Previous studies and precedents in relation to calculating damages from bid rigging suggest that the main issue was the lack of consideration in standards for deciding successful bids, selection of inadequate standard comparative markets, insufficiency in analyzing the appropriateness of competitive bid price influence factors, and absence of calculation model verification. In order to improve on these issues, a damage calculation method on alternative tenders for construction projects was proposed. For this calculation model, first, a standard market adequate to the successful bid selection standards was determined, second, an appropriate factor was selected by analyzing the correlation between competitive bid price influence factors, and third, a regression analysis was conducted on the selected factor. Lastly, this was demonstrated through verification of appropriateness, significance & normality of the proposed model and application of actual bid rigging cases. Through the proposed calculation model, this study seeks to serve as a base to prevent opportunity damages for parties involved in related court cases by early resolution of disputes and relief from issues of unfair damage burdens on a particular party.

This bridge was planed to be located in Geuk-rak river at south of Kwangju city. And it is very important to emphasis the beauty of bridge appearance. So Ive adopted unbraced tube arch type those linear beauty is elegance and simple. Actually, foreign bridges similar to this won various prizes for excellence of design. But there is no similar precedent in domestic highway bridge. therefore we intended to certify the security of this bridge through computational analysis. In this paper, approximate introduction of this bridge, design procedure and principal examination item is mentioned.

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.

한국건설산업연구원은 8 · 31 대책 이후 주택 시장의 불안정은 주택 수급 불균형 때문이라며 재건축사업을 활성화해야 한다고 진단했다. 도심지 내 주택 공급 문제의 근본적인 해소를 위해서는 각종 규제로 인해 교착 상태에 빠져 있는 재건축 사업을 활용해야 하며 이를 위해 경쟁입찰을 통해 선정된 사업시행자가 '일괄 매수 후 개발 및 분양하는 방식'을 새롭게 도입할 필요가 있다는 주장이 제기됐다.

Currently, TK(Turn-key) projects have been implemented, the projects on TK basis still have shown several problems rather than its own merits as a bidding method. Increasing the number of claims being occurred during construction process of the projects is reality because of unclear notice of tender documents and conditions of the contract, design review system, and decision process of the qualified bidder. To establish desirable TK projects in domestic market, not only should resonable alternatives for carrying out design review system and selecting the bid winner be set up, but also proper standards for reforming irrational system of contract, bid, and notice of tender related to TK projects. This study is intended to reduce the number of claims and implement efficient projects of apartment construction on TK basis by identifying potential problems through analysis of claim examples of TK projects which have difficulties of revising contract agreement such as drawings and suggesting improvement methods for contract conditions and notice of tender docuements.
