With increasing awareness on sustainable construction and green buildings, environment-friendly construction activities have been introduced and promoted. Green value engineering (VE) is an effort that is recently introduced to facilitate environment-friendly construction. To support the application of green VE in construction, this paper suggests a green value assessment model considering the environmental performance and carbon emissions during construction. The value assessment model presented in this study is expected to help conduct objective value evaluation of construction activities in terms of both cost and environmental performance.

This study was conducted to draw various decisive elements of a reasonable heat curing method and to examine the importance in deciding a construction method when constructing cold weather concrete. As a result, the items proposed as important elements at the time of decision of a heat curing method included economy, workability, maintainability, insulation capability, reduced construction period and usability. As a result of importance by items under AHP technique, it was found the most important element was insulation capability, followed by reduced construction period and workability. As a result of comparison of a heat supplying and a heat insulation method by dual bubble sheet differed 2 times as much as a heat supplying method, especially the evaluation degree by insulation capability and reduced construction period was high.

Recently, the scale of construction project is getting bigger compared to previous projects. Therefore, the job stress of the field manager responsible for the construction project is getting more and more intense. Therefore, construction companies should establish a job stress management plan for stable human resource management of the field managers. From this perspective, in this study was developed a job stress measurement system in connection with MBTI personality types. The developed system allows the job stress of the field manager to be judged on a scale from 1 to 9 points. Accordingly, it is expected that construction companies will contribute to the effective management of field managers in the future.

In most PFI(Private Finance Initiative) projects in Korea, the project management are in charge of the Special Purpose Company(SPC) established for carrying out the project. This paper is a case study about an owner CM executed by the organizations and staffs of SPC itself. : Seoulbeltway (Ilsan $\~$ Toegaewon) Private Investment Project. In time management area, the SfC was the leader of project management throughout the life circle - plan, design, permit, construction, operation and maintenance - beyond the schedule manager's role. In cost management area, the methods of reducing the total costs by VE, new technologies, etc. has been needed assuming the construction risks were subject to SPC.

Recently, the demand of sewage treatment facilities have increased by growing the population growth of city and industrialization. However, most of public sewage treatment facilities lack the preparations of design criteria by increasing sewage water amount in the future. In order to respond to this situation, the government has consistently promoted the sewage treatment construction project. This study conducted a survey targeting residents and sewage treatment facilities, civil engineering a VE project professionals for effectively operating the sewage treatment facilities and improving its value to be built in the future. Based on this survey, this study will introduce the list of performance measurements which can not only save cost but also reflect opinion of users and residents. In addition, using Multi-Level Performance Measurement and AHP analyzed the weights of performance measurement which is more objective than existing things for applying efficient VE process

Development work of apartment houses is a complex medium-and long-term project requiring grand resources and work force. Since in combination inner and outer project variables relate to project output, uncertainties caused by not only a given site condition but also politic, economy and social sectors are generated during the project. These risks influence output of the project as important factors, and ultimately as management variables in priority giving an effect on earnings and the financial structure of enterprises they should be manageable with the risk reduction plan. In this point of view, this study focused on development work of apartment houses among construction project. Risky factors were deduced, analyzed and evaluated based on Value Engineering from planning to designing to executing to maintaining. Eventually, this study showed the foundation guaranteeing competitive power of public and private construction sectors.

The CM at Risk project, which started with the aim of strengthening the global competitiveness of the domestic construction industry through innovation of ordering system, is being implemented in the form of pilot projects in the public sector. However, it seems that it is necessary to enact related laws and regulations to move to the formal ordering system, and the performance analysis of the project is still insufficient. In this paper, the effectiveness and reliability of the project were verified through the performance analysis of the Pre-Construction Service of the four pilot projects currently being implemented. The results of the study were analyzed in five areas including Team Building, Design Book, Construction Period, VE, and BIM. Through the interview survey, the problems were confirmed and improvement plans were presented. The results of this study are expected to be used as basic data for the legalization of ordering system to be implemented in the future.

건설사업의 원가절감은 사용자 요구에 부합되는 기능과 품질을 확보하면서 가장 경제적인 방법으로 시설물을 구축하는 것으로 건설환경 변화에 따른 경쟁력 향상을 위해서는 체계적인 원가관리를 통한 원가절감이 필요하다. 국토교통부 소속 산하기관에서는 공공건설사업의 수행에 따라 설계의 경제성 등 검토, 공정관리 및 사업관리 등을 통해 공사비 절감에 대한 많은 노력을 기울이고 있다. 현재 설계단계에서 설계VE 결과정보는 공공발주기관 간에 상호 공유하고 있으나, 시공단계에서의 원가절감사례 정보에 대한 공유는 아직까지 부족한 실정이다. 공공건설사업의 수행시 유사 건설사업에 대한 원가절감사례 정보를 참조 활용할 수 있도록 단계별 정보시스템 구축 및 원가절감 사례 정보서비스 방안을 제시하였다. 향후 공공건설사업의 기획, 설계, 시공, 유지관리 등 생애주기별 원가절감사례 정보의 분석 및 서비스를 통해 보다 합리적인 의사결정과 공공건설사업의 투자 효율성을 제고할 수 있으리라 기대된다.
