제출된 입찰서는 대부분 공개적으로 개봉하며, 입찰자의 명칭과 입찰금액이 함께 공표된다. 감리자는 입찰서가 산술적으로 정확한지, 요구된 자재 및 입찰문서의 조건에 부합하는지를 검토하고, 입찰자와 면담 등을 통해 입찰서의 평가를 완료한 후 발주자에게 낙찰(계약)수여에 관해 추천을 한다. 발주자는 낙찰된 입찰자에게 낙찰통지서(Letter of Award) 또는 낙찰(계약)의향서(Letter of Intent)를 발급해 시공자가 작업준비를 할 수 있게 한다. 낙찰통지서를 받은 시공자는 공사이행보증서(Performance Bond) 및 선수금 보증서(Advance Payment Bond)를 제출하고, 입찰보증서(Tender Bond)를 반환 받으며, 계약체결을 완료한다.

On public constructions, that the first planed projects delay than the scheduled completion day occurrence frequently because gap between the scheduled construction durations and the actual construction durations. These facts connect with not only problems of the construction during as the construction delay but also brought about the distribution costs increase as the failure of facility use plan and the people discomfort weight, failure of the production and the supply using facility then tremendous loss of each part etc. For reduce these loss, it must improve accuracy of the scheduled construction duration estimating when it order. This study try contribute to a successful manage of public project and reduce the construction duration extension frequent of the construction during, and then ensure the suitable construction duration by present the estimation model of the scheduled construction duration that include the construction duration correct element using as an index on the scheduled construction duration estimation.

우루과이라운드 협상에서 건설시장개방은 건설서비스로서 일반시장개방과 정부조달과 관련된 공공건설발주시장개방의 두 측면에서 이루어졌다. 정부는 건설시장과 함께 국내 건설관련 제도들을 계속해서 개선해 오고 있다. 제도 개선의 초점은 입찰, 면허제도 등과 같이 외국업체에 대한 영업자격부여방안이며 그밖에 감리제도 등도 부실공사방지대책과 맞물려 개선이 이루어지고 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.
