The BTL project, 4 years since its operation. has benchmarked the PFI Project in Japan and has been introduced. Given the evaluation step to select a preferred bidder, in a technological factor, the basic plans are corrected and complemented, whereas in a price factor, the low price bidding system is being enforced. There is concern that how to select preferred bidders and how to operate project costs during operation and management period may be problematic. Thus, in this study, using the Analytic Hierarchy Process, the method of deciding the priority to select preferred bidders in an early stage of the project and the evaluation model to evaluate the validity of BTL project expenses in process of project enforcement are established. Targeting the group composed of experts who have experiences in the BTL project. Then, the levelling of evaluation factors and grouping have been carried out as following : LCC analysis and disbursement for government including two more detailed factors.

Construction management services have been adopted for more than a decade and are continuously growing; however, the advantages of utilizing a construction management service are still not quite clear, regardless of many arguments can be made in their favor. The construction manager, as a coordinator, is supposed to smoothly facilitate the project teamwork in order to deliver a profitable and satisfactory project, not only for the owner's interests but also for the success of all project participants. This study has focused on the teamwork supports a construction manager can provide during project operations. This study developed a benchmarking tool to assess the construction manager's role in terms of its project teamwork supports, by utilizing the evaluation model and several case studies. In addition, this study also attempted to set the industry average and higher performance so that both the owner and the construction manager can self-assess, and more importantly, can improve project operation. The actual implementation of the benchmarking tool into on-going projects can allow the construction manager to understand the current operation and to make a better project process through teamwork.

Due to the diversification and complication of construction projects, controlling risks from the early design-planning phase gives huge impact on success of the construction project. As a part of managing uncertainties it is also important to estimate the project cost several times. Especially, estimating project cost in the early stage gives effects on making a budget for projects. This study estimated the apartment project cost using case-based reasoning(CBR), which is the process of solving new problems based on the past problems. For this, we deduced the apartment cost influence factors which can be gathered in the early stage of project. Based on the factors we established the database for apartment project and calculated the attribute value, attribute similarity and case similarity. Although we retrieve the most similar case from the database, it is very hard to utilize it directly due to the uniqueness of each project. So, Genetic Algorithm(GA) was applied in revising the cost of the retrieved-case. Therefore, the accuracy of the prediction was improved by GA optimization.

Many studies in risk management have been focused on management process, contract relation, and risk analysis in the past decade, but very few studies have addressed project risks from the perspective of risk efficiency. This study started with using Fault Tree Analysis to develop a framework for the decision-making support system of risk management from the perspective of risk efficiency, in order for the support system to find risk strategies of optimal combination for the project manager by the trade-off between project risk and cost of project strategies. Comprehensive and realistic risk strategies must strive for optimal decisions that minimize project risks and risk strategies cost while addressing important data such as risk causes, risk probability, risk impact and risk strategies cost. The risk management in the construction phase of building projects in Taiwan upon important data has been analyzed, that provided the data for support system to include 247 risk causes. Then, 17 risk causes were extracted to demonstrates the decision-making support system of risk management from the perspective of risk efficiency in building project of Taiwan which could reach better combination type of risk strategies for the project manager by the trade-off between risk cost and project risk.

The annual expenditure on diesel oil and heavy oil in the construction sector is the second largest among all industrial sectors. To meet the government's greenhouse gas reduction targets, the construction sector has until 2020 to cut its emissions by 7.1%. Unlike other high-tech industrial sectors, the construction sector has a fairly limited scope for technological improvements, which hampers its capacity to achieve the reduction target. To reduce emissions, it is necessary to establish an energy and emissions strategy at the project planning stage, and energy use and the resulting emissions must be estimated. This research aims to establish an estimation methodology for greenhouse gas emissions at the planning stage of construction projects. To estimate the project-related emissions, this research indentified the relationship among the types of emissions in a cross-sectional matrix form, and then provided a set of calculation methods for total project related emissions.

International construction contracts to Korean construction companies have been dramatically increased over the 48 years (Contract received worth 65.2 billion dollars in 2013). Especially, the plant construction sector has achieved about 61% among the 65.2 billion dollars. Under this trend, in order to ensure plant construction's competitiveness, 'standard classification' is an important area for systematic management. However, these standards in the plant construction are not widely utilized yet, in comparison with civil and building sectors. Therefore, in this research, a higher level of standard classifications is proposed for various types of power plants from a PMO's (Project Management Office) perspective. This study also provides a comparative analysis outlining different features and common components based on various types of power plants.

The Law of effective building and operation for the information systems took effect at Dec. 2005. Every government and public agency have to build own enterprise architecture(EA), sometimes it's called the Information Technology Architecture(ITA), by this law. The Ministry of National Defense(MND) built the enterprise architecture(EA) during 2006. 12$\sim$2007. 11 by this law too. We knew the specific characters of the public sector thru the EA project. The public sector is less active than commercial sector and most members of the public sector are just looking on the project as a spectator. So the most of key for the success of EA is how to catch the Sponsorship and Participation of members. In this paper we propose the effective building methodology for the Enterprise Architecture of public agency applying the MND-EA. The other governments and public agencies can build own the EA easily by the proposed methodology.

Integrating multi-trade works system helps to reduce to minimize the conflict of subcontract business and improve communication to increase productivity of construction. However it takes such a big risk if subcontract of integrating multi-trade works went bankrupt during the project so some of construction companies executed to only small project and it's not sufficient to adopt overall project. This paper suggested the improvement scheme of work classification integrating multi-trade works, which takes a consideration into work zoning in order to apply current work situation.
