「Act On Contracts To Which The State Is A Party」 stipulates that the "Construction Standard Production Rate" and "Construction Standard Unit Price" be used as the criteria for determining the estimated price of construction works performed by public institutions. In this regard, issues such as the application scope of the Construction Standard Unit Price, and the effect of budget reduction continue. However, due to the lack of quantitative data on the actual application of Construction Standard Unit Price, it is difficult to objectively evaluate various issues. In order to prepare data for objective evaluation of the Construction Standard Unit Price, this study analyzed the ripple effect of applying the Construction Standard Unit Price based on the bill of quantity. As a result of the analysis, the Construction Standard Unit Price ripple effect in the civil engineering part was 9.2%, and it was analyzed that there was a ripple effect of about 1.9% based on the civil engineering direct cost. In the construction part, the ripple effect was analyzed to be relatively high at 17%, but it was found to have a ripple effect of about 3% in the construction direct cost. Based on the total direct cost, the ripple effect was calculated as 2.2%. Based on the analysis results, it is possible to evaluate the effect of applying the Standard Market Unit Price, and it is expected to be used as basic data to solve issues. As a future study, it is necessary to additionally analyze the ripple effect by Standard Market Unit Price application range (over 10 billion, over 20 billion won, etc.) and delivery system type (comprehensive evaluation, qualification examination, technical bidding, etc.). In addition, it is necessary to study the appropriate ripple effect of the Standard Market Unit Price.

본 연구는 공공건설공사 중 조경공사 적산의 단가 비교로 적정 공사비 산출방안을 모색하고자 하였다. 2011년 상반기 실적단가에서 조경공사로 분류되는 12항목 중 유사기준인 7항목을 대비하며, 준용 공종은 5개 현장에 적용된 실적단가 80항목 중 비교 가능한 35항목을 유사기준인 2011년 3월의 표준품셈 단가로 대비하였다. 조경부문 7항목의 실적공사비율은 항목별로는 104.86%, 총공사비로는 92.09%이다. 실적공사비율이 높은 이유는 암반 적용 여부로 씨앗뿜어붙이기의 높은 비율도 있지만, 근본적인 이유는 잔디와 씨앗뿜어붙이기의 사면처리 비용 때문이므로, 품셈의 불합리성과 토양 종류별 기준별 보정계수 규정을 세분할 필요가 있다. 토목과 건축 준용부문 35항목의 실적공사비율은 항목별로 78.65%, 총공사비로는 71.31%(70.17%)이다. 이는 실적단가가 구조적으로 실제 금액을 반영하지 못하는 점과, 품셈은 인력시공에서 현실성이 결여된 때문으로 판단된다. 국토해양부 발표인 85.1~91.2%의 실적공사비율은 신규 전환품목 단가이므로, 이 결과는 실제적인 실적공사비율로 추정되며, 실적단가가 적정 비율을 보이도록 검증 후 보완하고 표준품셈도 이러한 실적자료 등으로 보완이 필요하다.

Construction Standard Unit Price is the unit price calculated based on the market price for work items in construction projects that have already been conducted. It is used as basic data for calculating the budget price of public construction projects. In the Construction Standard Unit Price Book implemented in the second half of 2020, there are 1,810 types of unit prices. Since 2017, 100-150 construction standard unit prices have been revised semiannually (on January 1 and July 1 of each year) through Construction Site Surveys. Other work items have been set based on the rate of inflation during the corresponding period. Later in 2020, this procedure was changed, with on-site survey period extended to one year to strengthen the construction standard unit price investigation. The revisions previous announced during the second half of the year were changed only to reflect the price inflation rates. With such changes in the revisions to construction standard unit prices, one important issue that was raised: The timing of announcing the revisions during the second half of the year (reflecting the price inflation rates). The market unit wage, which is the unit price standard of labor cost that takes up a large part of the construction cost, is announced in January and September. The figures announced in September is reflected on the construction standard unit price four months later in January, but the market unit wage announced in January is reflected only six months after in July, which causes a timing issue. As such, the current study analyzed problems rising from the changed timing of the announcements of the construction standard unit price during the second half of the year, in addition to analyzing their impact on public construction projects.

Dental prosthetic restoration shows a big difference of cost per itemized unit depending on the size of dental labs, facility standard, manpower, and performance. Even the same dental labs have distinctive cost according to manufacturing performance, inflation, and the number of workers. However, in apite of such a change of circumstances, it appears to be quite stable in the relative cost per itemized unit unless the manufacturing trend of particular item changes dramatically. Therefore, if the relative number of cost per itemized unit, which is produced by costing, is indicated, we are able to utilize it effectively as a standard wage estimate. If the wage of dental prosthetic restoration is determined on the basis of cost, it is desirable that the relative value of cost and that of wage are identical. But, by means of comparative analysis, since the relative value of wage reveals mostly lower than that of cost depending on an item, it is considered that the wage is not reflecting the cost approproately. Due to the subdivision and the profession of medical technology, the new development of wage items for dental prosthetic restoration is required. This means that the need for the establishment of new wage items should be presented as the general concept of dental prothetic restroation changes and the level of pathologic technology increases. The current wage structure has differences in the degree of difficulty accroding to unit items and in the cost factors. Nevertheless, the differences are not reflected enough to the wage, so there is potential to lower the medical quality through the use of low-proce materials to avoid the increase of cost and the work process which skips a manufacturing step. The new items of dental prosthetic restoration also increases, but the development of proper numerical value system is not supported. Thus, the right proce is set mostly by applying to the wage of a similar item. Since most wages are established by an individual agreement between the dental clinic institute and the dental labs, the propriety of wage level lacks. Therefore, it is urgent to provide and promote the system of a fair work charge by a standard cost which can be applied to all medical institute.

Unlike price calculation by cost accounting, which categorizes costs into material costs, labor costs, and miscellaneous expenses to determine the construction budget price, construction cost calculation based on Construction Standard Unit Prices utilizes unit prices extracted from market prices of items from projects already completed to estimate costs of similar construction projects. Although unit price information is collected through construction site surveys to revise these construction standard unit prices every year, but due to the limitations of the site survey method, it is difficult to quickly implement the rapid changes in the construction methods and market prices. As such, an important issue that arose was the identification of work items whose prices need urgent revision. This study conducted research on factors that need to be considered when developing online survey system for monitoring construction site market prices. This study is expected to enhance convenience for users, and provide an efficient data collection and management system for administrators.

표준품셈과 실적공사비 적산방식은 건설공사의 예정가격을 산정하는 가장 대표적인 기준자료이다. 하지만 이러한 공사비 산정방식은 1일 작업량 미만의 작업에서 정의, 할증 또는 보정기준 등이 명확하지 않아 적정 공사비의 산정이 어려운 실정이다. 따라서 본 연구는 1일 작업량 미만의 작업에서 표준품셈과 실적공사비의 문제점을 파악하고 이에 대한 개선방안을 제시하고자 한다. 이를 위해 본 연구에서는 경기도내 44개의 전문건설업체에 대하여 설문조사를 실시하여 빈도분석을 하였다. 본 연구를 통하여 표준품셈에서는 인건비, 실적공사비에서는 장비비, 공종별로는 도로포장 및 유지공사의 장비비가 각각 가장 높은 비율로 초과되었다는 결과를 도출하였다. 결과를 바탕으로 표준품셈과 실적공사비는 공사의 규모에 따른 구분 등 각각 3가지의 개선이 필요하다. 본 연구의 결과는 1일 작업량 미만의 작업에서 공사비 산정 제도의 개선을 위한 기초자료로 활용될 수 있을 것이다.

It is needed to classify the kinds of construction and demolition(c&d) debris to 6 catagories of waste concrete, waste asphalt concrete, waste wood, scraps, combustible waste and incombustible waste in order to properly do a separate discharge and to estimate unit generation rate in construction site. Also, in this case, the unit treating cost for mixed wastes should be applied with the unit treating cost for combustible waste. The construction standard materials estimation data is used for basic data for estimating unit generation rate. The mixed wastes in this data should be classified to waste wood, combustible waste and incombustible waste, and their ratio is obtained by using the unit generation rate of Asia Pacific Environment and Management Institute and Seoul Metropolitan Development Institute. The waste amounts generated from newly-built construction can be obtained from multiplying the loss rate by the amount of materials used from construction standard estimation data. Also, those from dismantling construction can be obtained by subtracting waste amount generated during newly-built construction from total input amount of materials in newly-built construction. Those in two cases can be used in construction site. It can be used for estimating the amount generated and establishing the treating plan in the case of setting up the policy of waste management and doing the environment impact assessment.
