전주시는 올해 보안등의 신설 또는 개체가 필요한 일부지역에 ESCO사업을 통한 보안등 교체공사를 실시해 밝은 거리 조성에 나섰다. 예산부족에 따른 사업비부담과 전력요금부담을 덜면서 민원을 해결할 수 있는 방안으로 ESCO사업을 추진한 것이다. 에너지절약성과가 가시화되고 사업의 성패여부가 판가름나는 내년부터는 다른 지역의 자치단체에 미치는 파급효과도 클 것으로 예상된다.

The main purpose of Construction Management(CM) is the improvement of efficiency and effectiveness of the project with construction methodologies systematically and technically. This pilot project Dong Myeong Service Area and Gas Station project among 5 projects designated and supervised by Ministry of Construction and transportation(MOCT), is to reduce cost, to maintain and control schedule, to keep proper quality, Claim and Risk through Partnering, Design Review, Constructability, Value Engineering and Project Management Information System(PMIS) and so on. Major factors of CM Plan are introduction of the phased and classified Construction Management Services from initiation of project to completion and adaptation of CM technologies and guide the implementation methodologies of the CM Pilot Project in CM construction market.

While a detailed cost estimation utilizes the comprehensive quantity information obtained from a complete drawing and specification, an approximate cost estimation heavily relies on the subjective decisions. This phenomenon is because the approximate estimation is usually conducted in early stage of the construction phase where the drawing and specification are not available. This study developed a roadway construction cost estimation system which enables users to estimate the approximated cost of the project in early stage. The system identifies the variation of the construction costs due to the road route change using a cased based reasoning(CBR) method. Overall the system is expected to improves the accuracy and effectiveness of the estimation process, because it would provide users with increased accessability and consistent results in early stage of the project which leaded to the increased work transparency.

The railway route and alignment planning have been executed with a limited number of alternatives based on the site pre-survey and the topographic map. This study developed an intelligent railway alignment planning program (ei-Rail) which can derive all the considerable design alternatives and provide the data for the alternative evaluation such as constructions cost, operation cost, and etc. According to the comparisons with prevailing planned railway projects, the time and cost for planning can be reduced as well as the construction costs. This program may contribute to the development of railway industry by reducing the time and cost for planning as well as the total project cost.

The purpose of this study is to examine the problem of BTL(Build Transfer Lease) projects through comparative analysis on running costs, focusing on primary school, junior and senior high school education facilities, and then to provide useful information on the estimation of running costs by suggesting valid cost criteria. For this, eight schools from A and B consulting firms were sampled from capital region and other areas. Sampled schools were classified into four categories according to school grade, and running cost data are collected and analyzed from relative view points. The results of this study are as follows: 1) running costs which are analyzed by categories show some difference among sub-items, 2) major problems related to running cost prediction of BTL projects are revealed and improvement schemes are suggested for two groups (Owner and Project applicants).

With rapid industrialization since the 1960s, development projects have contributed to the development of the national economy. In addition to the development projects promoted by the government, private project operators are also promoting development projects for reasons such as increased public convenience, insufficient financing of SOC assets, and expansion of their own development projects other than public orders. However, as the economy has been stagnating due to several factors such as continued supply of facilities for decades and recent COVID-19, the success of the development projects are unsure these days. Therefore, this study attempted to analyze project costs through the case of such development projects, and to present a plan to judge and manage the risks of each project cost item in advance. The AHP technique, which is widely used as a risk factor selection method for existing development projects, was used, and items were determined through interviews with experts related to development projects in order to stratify the upper and lower subjects of the risk. We analyzed how the derived risk factors affect the business performance through sensitivity analysis, and finally substituted the risk factors management plan into the risk response strategy and suggested.

The purpose of this study is to examine the civic participation in supply process of social welfare services in the Japanese communities and to detect the background that how "Non-profit citizen welfare organization" emerged as a social welfare service supplier of local government. Furthermore the effect of Non-profit citizen welfare organization on the expansion of employment opportunities for women is also analyzed in this study. In order to investigate the background of the emergence of non-profit citizen welfare organization as a social welfare service supplier, this study approached not only from the viewpoint of the trends of welfare pluralism followed by the crisis of welfare states, but also from the viewpoint of how local government solve the problems of consumption flexibility on welfare services. In addition, to examine the effects of Non-profit citizen welfare organization on the expansion of employment opportunities for women, a case study on the employment function of non-profit citizen welfare organization is also carried out in this study. The various background how non-profit citizen welfare organizations emerged and the employment effect from those organizations are empirically analysed through the methods mentioned above.

Natural stream disasters due to a localized torrential and flash flood has occurring in a small stream especially un-implemented small stream. The survey results during ten years from 2001 to 2010 show that the small stream implementation projects (SSIPs) expenses is increasing with the damages is generally decreasing with variableness in which SSIPs is contributing to disaster prevention in a small stream. This study develop guideline for the selection of SSIPs to support high risk stream at first and save the small streams located on the mountainous area, prevention area and agricultural area which streams have no implementation effects. Developed sub items in guideline are evaluated by stream data collected from 212 small streams where it is proved that sub distance of each item are well arranged by normal distribution. This SSIPs is useful for selecting high risk small stream at first to maximize disaster risk reduction with minimum SSIPs expenses. Also, this SSIPs is used for leading to save small stream on the upstream to minimize flood damages on the down stream with selection a SSIP purchasing agricultural land for preparing flood plane.

Predicting accurately the construction cost budget in the early stages of construction projects is crucial to support the client's decision-making and achieve the objectives of the construction project. This holds true for public construction projects as well. However, the current methods for predicting construction cost budgets in the early stages of public construction projects are not sophisticated enough in terms of accuracy and reliability, indicating a need for improvement. The objective of this study is to develop a construction cost budget prediction model that can be utilized in the early stages of public building projects using an artificial neural network (ANN). In this study, an artificial neural network model was developed using the SPSS Statistics program and the data provided by the Public Procurement Service. The level of construction cost budget prediction was analyzed, and the accuracy of the model was validated through additional testing. The validation results demonstrated that the developed artificial neural network model exhibited an error range for estimates that can be utilized in the early stages of projects, indicating the potential to predict construction cost budgets more accurately by incorporating various project conditions.

ESCO사업은 진단에서부터 출발하지만 그 종착역은 사후관리에 있다. 우리가 만난 많은 에너지사용자들은 ESCO사업 추진동기를 ''사후관리''때문이라고 말하는데 주저하지 않았다. 그만큼 다른 일반 사업에 비해 ESCO사업에 있어서 사후관리는 중요하다는 이야기가 된다. 지난해 ESCO편집부에서 취재한 ''화제의 ESCO현장''중에는 당시 사업이 완료된 곳도 있었지만 진행중인 곳도 있었다. 이번 호에는 사후관리의 중요성을 강조하자는 취지에서 사업의 후기를 들어본다. 대부분의 현장은 ESCO사업 실시에 대해 긍정적이었으며 원활한 메인티넌스가 확보되어 만족한다는 답을 해왔다. ESCO사업의 긍정적인 측면을 보는 것 같아 안심이다.
