추가공사 발주를 미끼로 하도급 대금을 일률적으로 인하하고 다량 발주를 전제로 하도급 대금을 부당하게 감액하는 등 불법.불공정 하도급행위에 대해 법원이 철퇴를 가했다. 광주지법 순천지원 제1민사부(재판장 선재성 부장판사)는 모 하도급업체가 하도급대금미지급 및 부당한 하도급 대금 결정 등으로 손해를 봤다며 자신과 거래한 원도급업체를 상대로 제기한 손해배상 청구 소송에서 "원도급자는 하도급자에게 미지급 공사대금 3억8천600만원과 부당한 하도급 대금 결정에 따른 손해배상금 1억1천500만원, 계약부당 파기로인한 손해배상금 4천200만원 등 5억4천300여만원을 배상하라"고 원고 승소 판결을 내렸다고 밝혔다. 이번 재판은 법원이 하도급대금 미지급 분만 아니라 그 동안 하도급업계에 관행으로 여겨졌던 추가공사 발주를 미끼로 한 하도급대금 감액, 부당 계약해지, 추가계약 교섭 일방파기 등에 제동을 건 것이어서, 앞으로 하도급대금 결정 과정에 상당한 영향이 미칠 것으로 보여져 그 파장이 클 것으로 예상된다.

Despite the many advantages of modular housing, low preference for modular housing for consumers who are familiar with RC structure leads to high construction cost of modular housing. The cost of modular buildings is about 130% of that of RC structures, so it is urgent to secure economical efficiency of modular buildings. Therefore, in this study, after calculating the savings amount of modular housing by type of construction work, economic analysis was conducted from a long - term perspective. In order to carry out the research, the authors compiled and analyzed the material cost, labor cost, and expenses incurred by each type of work by reclassifying the statement of the modular housing into the factory production and the site installation. After that, Pareto diagrams were created to find a core work that is included in the cost ratio of about 80%, and selected it as a cost reduction subject. Based on the assumption that the market size of domestic modular housing is similar to the level of modular advanced countries such as Japan and European countries, six cost reduction methods were set up that reflects the characteristics of the modular construction method and used for the expert interviews. Cost saving potentials in percentage from the interview were converted to the amount of savings that can be achieved by each type of method when applying the method. Finally, the findings of the study are expected to suggest long-term directions for technical development for modular construction and cost savings.

The purpose of this study was to analyze on changes of ready constructed record(RCR) in landscape construction industry for 10 years from 1997 to 2006. For the study, according to the classification system of Korea construction industry, landscape construction industry were classified into landscape constructor as a general constructor, landscape planting constructor and landscape facilities constructor as special constructors. The results are as follows: 1. The RCR in landscape construction industry have increased for 10 years higher than other construction industry. Concretely the RCR ratio of landscape constructor has increased 0.9% in 1997 to 1.9% in 2006, the RCR ratio of landscape planting constructor 1.3% to 2.5%, and the RCR ratio of landscape facilities constructor 0.5% to 1.5%. Futhermore this increasing trend has been strengthened during the last a few years. 2. Differently from landscape constructor, the subcontract ratio of landscape planting constructor and landscape facilities constructor were higher, especially landscape facilities constructor was highest amount for 71.1% in the subcontract ratio. 3. The RCR of landscape construction industry in the metropolitan area including Seoul, Kyunggi, was higher than other region's, and the ratio of RCR of landscape constructor in this area was 53.5%, landscape planting constructor's 58.2%, and landscape facilities constructor 75.0%. 4. The yearly RCR per company and the RCR by project of landscape constructor and landscape planting constructor were stagnant. However, landscape facilities constructor's RCR showed an upward trend as years go by. This study was focused on the RCR of landscape construction industry, further study on the factors to affect the RCR of landscape construction industry and the RCR by project types is required in the near future.

Delay schedule coming about duration extension is happening essentially because public construction project consist of many sub contractor. The method which can calculate delay day is suggested by many studies in case of happing delay schedule, but It is difficult to apply to real construction project because there is no mention about the control of The law of contract according to delay schedule. The law of Contract which is cost of account has more uncertain problem than FIDIC condition of contract. This study suggests method which can make extension of duration procedure clear in case of happing the reason of design change related with activity duration during carrying on construction, and a submission process of the reason of duration extension and modify schedule making way about section which is basis of calculating contract amount clear.

Under Korean law, small-to-medium-sized construction projects with budgets of more than 100 million won and less than 12 billion won must receive technical guidance by a visiting technician belonging to a specialized institution. This study proposed a method for calculating the technical guidance fee to prevent the potential inadequacy of technical guidance when the responsibility providing the technical guidance fee is changed from a contractor to a client. The method simplified the construction works which should receive technical guidance into four sections according to the construction amount. For each section, the number of instances of technical guidance per day provided by the visiting technician and the minimum technical grade of the visiting technician were limited, and the guideline for estimating engineering services fees was applied to calculate the fee per instance of technical guidance. The results show that the proposed method can be applied to the establishment of a technical guidance fee guideline since it well reflects the current fee distribution and K2B analysis results.

Construction business, which is complex and long-term business, requires accurate estimation and verification in construction costs and payment procedure from project planning to the completion of construction phase. And more importantly, it is necessary to investigate and determine the risk factors related to construction costs during the entire process including design planning, construction drawings, and quantity calculating. But, currently, it is not seem to be adequate to cope with the risk and increased construction costs against the operational budget in terms of actual costs when screening and estimating the bidding cost of public apartment. Therefore, this study selected and analyzed 40 sites' report of construction completion account from 2004 to 2010 focused on the adequacy on the modification of contract and design planning and on the complication of the budget in the beginning of the project. This study deducted various risk causes and results by analyzing actual costs according to year, architectural area, region, construction cost and sale/lease classification. We could find out construction risk according to annual variation of government policy and economy, and also deducted risk items by construction characteristic according to region and architectural area. Study result, we first found out the problems of lowest price award system according to the construction costs. The weight of the cost increase risk was analyzed that subcontract and material costs are very high. Roof and tile work were analyzed highly in subcontract cost risk and reinforcing bar and cement were analyzed highly in material cost risk, among direct construction cost. Finally, this study results could be used in comparing the categories of the construction costs made by specific construction process, belonging to the construction costs, with the operational budget made in the beginning of the project that can enable to grasp unpredictable risks over the construction costs and making quantitative analysis for it through analyzing the range of fluctuation and variations led by the fluctuations in the actual construction costs.

안전행정부가 지방 중소기업의 입찰참가 기회를 확대와 하도급업체 보호 강화를 주요내용으로 하는 "지방자치단체 입찰시 낙찰자 결정기준"과 "지방자치단체 입찰 및 계약집행기준" 예규를 개정하고 7월 1일부터 시행에 들어갔다. 개정된 예규에 따르면 중소기업 지원과 입찰 참여 확대를 위해 5억원 미만 주계약자공동도급 공사에 접근성 평가를 도입해 지역 중소업체의 입찰 참가를 확대하도록 했으며, 하도급업체 보호를 위한 방안으로 원도급자가 하도급계약을 체결하면서 지나치게 하도급금액을 낮추거나 하도급 표준계약서를 사용하지 않거나 하도급 내용을 부당하게 변경하는 등의 사례를 방지하기 위해 공사 적격심사기준을 강화했다.

The purposes of this study is to survey unfair aspect of specific provisions in the construction contract. The research method of this stud)'includes judicial precedents and a questionnaier survey. The result of thus study are as follows: 1) unfair payment condition gives increase to faulty construction. 2) shift of the responsibility gives increase to delay, 3) adjusted contract sum gives increase inappropriate compensation to contractor.
