Purpose: The purpose of this study is to provide an effective construction project cost estimation tool for preparing a business plan of healthcare facilities which can be practically used for development projects. Methods: In order to provide a tool for calculating construction project costs, this study analyzed the Building and Related Laws, the Building Technology Promotion Laws, the Ministry of Land, Infrastructure and Transport notifications and directives, the Ministry of Trade, Industry and Energy notifications, the detailed guidelines of the Ministry of Strategy and Finance, the Building Service Industry Promotion Acts, various certification standards, actual project budget calculation cases, etc. with advices from related experts. Results: 1) Construction cost is classified into construction costs, architectural design costs, supervision costs, incidental costs, and each sub-element. In particular, since there are many incidental cost items, essential items to be reviewed during planning are derived and costs are calculated according to appropriate consideration criteria. 2) Criteria for Payment calculation mainly applies the construction cost rate method or the actual cost fixed amount method in consideration of the characteristics and scope of work. Implications: There are many calculation factors that need to be applied to the construction project cost. Therefore, it is necessary to organize the calculation process more clearly.

Nuclear power plants in Korea are usually built based on a duplicated model; so the project cost data of the preceding unit can be used as reference when estimating the project cost for the succeeding unit. However, since the contracting method is oriented towards the price, empirical factors such as making top-down estimations using the reverse calculation method based on the completion cost of the preceding unit is dominant. In order to develop a project cost database to resolve such problems, the detailed cost boundary of the project cost data must be categorized by project and by system. This study proposes a method to connect the code of account with the base quantities and the IAEA account, and proposes a database structure for the development of a project cost estimation system. The estimation system developed in the future is expected to utilize the proposed project cost data structure.

Estimating the reasonable construction-cost according to the construction phase in public construction is an important element for securing and executing a national budget efficiently. As a general rule, the predetermined cost of construction is estimated at the end of the design of the target structure. Therefore, it seems to be a considerably difficult problem to estimate the approximate cost of construction, only with its basic information of the bridge in the design planning phase and the early design stage where we can not have specific detailed-section of the target structure. In this paper, we present the calculation of construction-cost in the planning phase based on the analysis of factors affecting the cost of construction conducted in the previous study. Beside, to estimate the cost of construction in early design phase, we would like to present the calculation of construction-cost in the early design phase by executing the analysis of data collected from 61 steel box bridges. It was found from the result of study that the estimated cost of construction gained by the calculation of construction-cost in this paper reduces the error between the real cost of construction and that by the existing method of using.

In the Construction Technology Promotion Act (CTPA) of the Republic of Korea, safety management cost is enforced as a statutory cost that must be included in the budget of construction projects. However, the construction of underground electric power transmission facilities (UEPTFs) is not included in the category of construction works defined in the CTPA. Consequently, the statutory safety management cost does not apply to the construction of UEPTFs. To overcome this limitation, the clients of UEPTF construction projects generally provide internal guidelines enabling the addition of the safety management cost in the project budget. Nevertheless, even after the execution of the internal guidelines, some important cost items are omitted from the budget owing to the incompleteness of the guidelines. In this context, this paper proposes a complete set of accounting items and their calculation methods for appropriate budgeting of the safety management cost of UEPTF construction projects. To this end, the current budgeting method of the safety management cost of UEPTF construction projects is analyzed, and a questionnaire study is performed to confirm the necessary cost items and their appropriate calculation methods. Based on the results of the questionnaire study, a set of accounting items and their calculation criteria for the budgeting of the safety management cost of UEPTF construction projects are proposed.

수질오염총량관리제도 추진 절차 중 시행계획 이행평가 사업의 대가는 기존 환경부 용역비 지원기준에 따라 산정하고 있다. 그러나 용역비 지원기준은 기본금에 해당 유역면적과 인구 규모에 따른 가산금을 합산하여 대가를 산정하도록 구성되어 있어 사업의 특성을 상세히 반영한 대가를 산정하기 어려운 구조이다. 따라서 본 연구에서는 이행평가의 상세 업무별 영향을 미치는 요인으로 단위유역별 면적, 인구, 축산 두수, 폐수배출업소 등을 반영한 표준품셈을 적용하여 대가산정 방안을 제안하고 그 적정성을 검증하였다.

Regarding the implementation of ROMM project (Rehabilitation, Operation, Maintenance & Management), which is one of overseas development projects, it is very important to diagnose the exact current status of aged thermal power plant. However, when people visit the power plant for the purpose of prediagnosis to implement the ROMM project, most target power plants for diagnosis, in general, are under operation. This can be a big interference factor to diagnose the exact current status of power plants. Therefore, in order to solve such interference factor, based on the 30 years of know-how in the field, the present study has developed a regression curve for a simple life time assessment and the calculation of rehabilitation cost that may be used as a reference relatively for the quantitative diagnosis on the status of a relevant power plant even during the operation of the power plant.
