건설공사 분리발주가 공공의 이익이 매우 큰 것으로 분석됐다. 또 분리발주로 인한 공사지연, 하자분쟁 등 효율성 저하는 철저한 공사관리와 발주자 보호장치 활용으로 해결, 일부의 우려는 기우에 불과하다는 분석자료가 나왔다. 대한건설정책연구원(원장 노재화)은 박근혜 정부의 주요 국정과제 중의 하나인 공공공사 분리발주 법제화의 효과를 분석하고 향후 도입방향을 제안한 '공공공사 분리발주 법제화의 효과와 도입방향' 보고서를 발간했다. 홍성호 연구위원이 발표한 이 보고서에 따르면 공공공사의 20% 수준으로 분리발주 적용범위 결정 시 4,693억원의 공공예산 절감과 4,198억원의 부가가치, 2만6,048명의 고용이 증진되는 등 공공의 이익이 매우 큰 것으로 밝혀졌다. 또한 발주자 선택권과 자유계약 원칙을 중요시하는 미국, 일본, 독일 등 선진국도 분리발주의 법제화 또는 적극적인 활용을 통해 공공예산 절감, 부가가치 및 고용창출효과를 거두고 있을 뿐만 아니라 통합발주의 문제점도 해결하고 있다고 밝혔다. 선진국은 또 전기 소방 통신 설비공종 뿐만 아니라 건축 및 토목공종에 해당되는 여러 개의 공종을 분리발주하는 다공종 분리발주 방식을 많이 활용하고 있는 것으로 나타났다. 연구원은 또 일부에서 우려하는 다수의 공종 패키지로 인한 효율성 저하는 통합발주에서도 동일하게 발생하는 현상이며 철저한 공사관리와 발주자 보호장치 활용으로 해결 가능하므로 이같은 우려는 현실성 없는 기우에 불과하다고 밝혔다. 이와 함께 분리발주로 인해 발주자 관리업무는 일부 증가하지만 건축 및 토목공종의 일부만 분리된다면 그 증가폭은 크지 않아 크게 문제되지 않고 있으며 향후 CM용역을 통해 충분히 해소 가능할 뿐만 아니라 오히려 건설산업 발전에 필요한 'Smat 발주자 육성'이 가능하다고 전망했다. 본지는 지면관계 상 연구논문 중 공공공사 분리발주 도입에 따른 효과와 공공공사 분리발주의 도입 방향 부문만 게재한다.

Occasionally an owner of public construction work pays financial costs in addition to progress payments. However, the overall scale of financial costs are not known. This research examines, based on a case study, the financial cost incurred in public construction works and the following issues: the overall scale of financial costs, the impact on financial costs on the owner, and the impact of timing on the overall sum of the financial costs. Annually, more than 2.3 trillion KRW are paid as progress payments for public construction work; yet, there is no research data showing the scale of financial costs thus incurred. The purpose of this research is to illustrate the scale of financial costs incurred due to progress payments for public construction works, and to suggest alternatives that would improve relevant regulations.

지방자치단체의 계약업무에 기초가 되는 지방계약법 시행령이 지난 11월 24일 공포되어 시행에 들어갔다. 이번 지방계약법 개정은 지난 해 12월 30일 개정된 국가계약법 시행령 제68조와 동일하게 제77조를 신설하여 '하자책임 구분이 용이하고 공정관리에 지장이 없는 공사에 대하여 기계설비공사와 같은 '설계서가 별도로 작성되는 공사로 명시함으로써 공공공사의 분리발주 활성화를 유도하는 내용을 담고 있다. 이로써 지방계약법에도 분리발주 허용 대상을 구체화 하고 발주기관의 장이 공사의 예산편성과 기본설계 등 사업의 계획단계부터 분리발주의 가능 여부 검토 조항이 명문화 됨으로써 지자체 분리발주가 더욱 활성화 될 것으로 예상된다. 이에 앞서 대한설비건설협회는 분리발주 법제화를 정부, 국회, 제18대 대선후보 등에 지속적으로 건의한 결과 박근혜 정부가 공공공사의 분리발주 법제화가 포함된 40대 중점 국정과제를 확정하고 공공공사의 분리발주 허용 대상과 활성화 조문이 포함된 국가계약법 시행령 제68조를 지난해 12월 30일 개정, 시행에 들어간 바 있다.

This study analyzes necessity of expanding construction insurance and estimates required budget. Construction insurance is obliged by National Contract Law and Local Contract Law to protect projet owners and contractors from any unexpected construction risk such as financial losses in construction process. Currently the contracts of design-build and alternate-bid projects as well as PQ project, which are greater than 20 billion won, require the contractors to provide construction insurances in Korea. Insurance premiums are borne by the public project owner. Those contractors whose contract volume is less than 20 billion won burden all risks of projects at their cost. This causes equity problem. Because small-and-medium contractors are discriminated against large contractors since insurance-obliged projects are performed by large contractors and insurance premiums are borne by the public project owner. On the other hands, in all engineering projects, regardless of volume, insurance premiums are borne by the project owner. Therefore current regulation has to be improved, by expanding to all public projects. The average ratio of unobliged projects is 46%, in recent 3 years, prime cost of insurance companies is estimated 0.2%. Moreover considering risks of each construction type, prime cost of unobliged works is estimated as 0.13%. Hence additional necessary budget is estimated to be 2.09 billion won if total volume of public work is 3.5 trillion won. And 2.39 billion won is derived if total volume of public projects is 4 trillion won.

The contract price of successful bidders in domestic public work projects has dropped significantly under lowest bidding process. Furthermore, compared to the U.S. and Japan, the bids are substantially lower. The increasing trend for domestic construction companies to bid projects without considering markup or expected profit, with the purpose of gaining experience for future similar work, has contributed to the overall dumping in bid prices. The government has implemented controls in hopes of reducing the price dropping trend but these have yet to work in the market. This study determines the level of significance of the contract price of the successful bidder in domestic public works projects and identifies factors that cause bid-dropping by comparing to those of the US and Japan. By mirroring advance countries' rules and regulations to prevent an abnormally low bidder, recommendation are provided to keep unrealistically low bidders from winning the work.

As the government has enforced recently the policies on the distribution of the housing, the construction cost of multi-family housing projects has increasingly become very sensitive and political issue. However, it is difficult to predict the construction cost in planning and design phase of the project because the Bill of Quantity of the multi-family housing projects was composed of breakdown structure based on each work package. To predict the construction cost in planning and design phase for multi-family housing projects in more effective and reasonable way, this study developed the cost breakdown structure based on spaces using Delphi method. The Cost Breakdown Structure (CBS) based on spaces for multi-family housing projects basically consists of three parts: (i) Building part; (ii) Non-building part; and (iii) Additional part. The characteristics of spaces in multi-family housing projects are fully taken into consideration. Then these three parts were subdivided into work packages in terms of work tasks. Additionally, the usefulness and effectiveness of Space CBS in this paper were validated by analyzing the BOQs of several collected sample projects and matching with Space CBS afterwards.

Domestic construction industry accounts about 15% of Gross Domestic Product(GDP) and Korean government spends approximately 50 trillion won per year for public infrastructure projects. Effective management of public construction projects would result in cost saving and enhance financial stability of the government. In doing so, the government promoted a new budgeting system, Continual Budget Method(CBM) as a part of public project performance enhancement program published in 1999. This research mainly attempted to investigate and analyze the impact of new budgeting in term of cost and schedule performance. Based on the analysis result of n2 projects. The new budgeting system could save project cost by 9.83y. Due to the saving of indirect costs from reduction. Although limited government budget cannot allow all the projects to be excuted with the new budgeting system, the new budgeting system should be more-widely utilized in the public sector because of its proven benefits from this research.

In the construction project, construction supervisor influences greatly the construction managements such as process management, quality management, safety management, and cost management. Therefore, from the first stage of the project, the managing activities of the supervisor are consistently needed. But the assesment of supervisor's work and cost has not been made enough in the public construction project. And there have been doubts as to whether a supervisor can take a consistent managing activity from the early stage of the project. Accordingly, the works between Korean supervisor and foreign supervisor in their public corporations are analyzed and compared in this paper. And the evaluation is made each of the cost for supervisor and the cost for engineer as a substitute of supervisor in construction project. This study is believed to contribute to improving the supervisor's work and reducing the personnel expenses and construction indirect cost.

In domestic public works, there are several problems in the measurement of payments based on the bill of quantity, which doesn't match with the activity progress rate, heavy paper works and complicated procedures. It can be classified formal and simplified method. By using the simplified method, it can be solved many problems by summarizing the procedure, but is not generally used. This paper proposes a payment method by progress measurement for specified activity based on WBS(Work Breakdown Structure) verifying efficiency which reduced cost account and advanced work on payment compare to method of domestic public works using the data about construction of eco-river. This method will be an important contribution on being a base for cost-schedule integrated management which were verified and also improving efficiency on measuring payment.
