Today's businesses are experiencing intensive global competition and the most accelerating pace of change ever. Competitors have sprung up that were not even on the business's radar. This environment impacts all decisions and strategies as business try to dominate their market or their marker or their industry merely to survive. So recently most of organizations are considering on building the data warehouse system to pursuit the business intelligence. We need the proper model to guide the approach to plan building data warehouse system when we want to plan it in considering the organizational status. Therefore we suggest a model to decide the approach to build data warehouse considering the project's environmental factors. First we review Ronald S. Swift(1998)'s five environmental factors that we have to consider when planing to build data warehouse. Then we propose a model to decide DW approach by the degree of those factors to be measured. DW approaches in this model are classified in conservative approach, increasing approach, enterprise wide approach, and ideal approach.

Professional Construction Management (PCM) services have become more and more popular in Taiwan in the past decade. However, disputes between PCM consultant and the client on the performance of PCM services are also increasing. The evaluation of PCM performance is a tough task due to the lack of "physical product", such as the drawings finished by the architect. This paper is intended to propose a PCM performance evaluation system (PPES) based on Balanced Scorecard (BSC). A case study of PCM consultancy for a real world design/build project is conducted to demonstrate the applicability of the proposed BSC framework

Private companies will get back their investment by leasing facilities to the government, Since act on private participation in infrastructure were changed in January 2005, BTL(Build Transfer Lease) project of introduced in the domestic construction market for the purpose of providing public facilities with the public. BTL projects is for with approximately project life cycle form plan to maintenance the success of the project totally depends on the capability and role of concessionaire. Accordingly, this study is aimed to improve in order to proceed with BTL project efficiently, a clear standard for the item of evaluation was presented.

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.

The Build-Transfer-Lease (BTL) projects have rapidly increased under the Government support during recent years. This paper presents the risk analysis of factors affecting BTL projects in the initial phase. This study resulted in 10 significant risk factors influencing on each phase of BTL projects and then factors were grouped into each phase. The sensitivity analysis was also performed to identify risk factors with more significant influence on BTL projects. The results may useful to practitioners in order to cope with risks in initial phase of BTL projects. The paper resulted in the distribution of risks to project parties, thus it can be used as standards for risk assignment to competent authorities and private enterprises of BTL projects.

Since standardization project is composed of complicate system, such as vehicle, signal, electric power and railway, how to build management system of the project has influence on the success of the project for the first stage of the project. The computer system design tool supports to carry out requirement analysis, DB construction, and history and follow-up management efficiently. Therefore, the aim of this study is to investigate the method to optimize schema using computer system design tool.

The orders of Design-Build Delivery System (DBDS) in a large and public construction project have been increasing. Single Source Responsibility (SSR) for design and construction, which contributes to quality improvement of design and construction, has been performed. The DBDS performs SSR for design and construction, but, it has not maximized effect because of the dissatisfied alternative analysis procedures which are based on constructability evaluation and the information system in the design step. In this research, Constructability Evaluation Factors (CEFs) that must be evaluated, investigated, and reflected in the basic design step for design-build projects. The CEF proposed and the business process of each conductor has been systematized. To propose constructability evaluation factors, first classify drawing information by the constructability evaluation sphere. CEFs must be proposed to evaluate factors according to interference among work items. Second, applicable CEFs must be classified by preference ranking and weight. Third, the values of constructability factors in accordance with building elements and work items, need to be calculated. Finally, the CEFs proposal will support rational decision making, design cost reduction, and quality improvement through the values for constructability of building elements and work items.

Although the design-build (DB) delivery system has been taking great strides in the world and relevant researches have also been quite abundant, few studies have dealt with its potential impacts on the construction industry as a whole. This research first identified the potential entry barrier factors, which may hinder the market access, based on the theory of industrial economics and characteristics of DB project. Then through a nation-wide questionnaire survey involving 103 construction contractors and engineering consultants, the influences of each factor on company's competitiveness and corporate strategies were scrutinized, and consequently, the evolution of the construction industry was examined. It is found that as opposed to the traditional design-bid-build delivery system, the DB delivery system elevates competitive advantages of large organizations in terms of the financial capability, working experience, human resource, and administrative strength, and among them, the financial strength was concluded to be the most significant force in differentiating corporate strategies and widening the gap of competitiveness between companies. It is inferred if the government extensively adopts DB delivery system, large organizations that already possess the competitive advantage tend to obtain both design and construction abilities, and dominate the DB market. Small and medium sized companies will find little room to maneuver and be forced to become specialty sub-contractors.

Although the order of Design-Build is being expanded by increasing construction scale and demanding hybrid function, the suitable regulation of the contracts is not settled. Design-Build is way by government because there are big construction of much government leading in contract relation high position occupy. So, case that prebendary's claim institution develops by litigation is very rare. But, recently Design-Build is magnified. So, these dispute factors is becoming visualization gradually. The contract system is needed to be consistent by international standard to deal with the problem. This study suggests the useful solutions in detail concerned with the main factor of change order claim by each Design-Build phases through practical sorting and analysis of the causes of Change Order-Claim.

The purpose of this study is to apply efficiently a successful Project Finance in BTL. To use Project Finance, it is necessary to Risk Analysis of each work step. This Risk Analysis have to repeatedly progress in overall Project Process. The differences between Corporate Finance and Project Finance are remarkably appeared in Risk Allocation and Limited Resource. To use successful Project Finance in construction industry, first, raising project confidence, second, technical : economical : lawful evaluation by Finance Expert, third, Income Guarantee for Lender or Consortium of Lending Banks, forth, Leverage Effect of Project Sponsor must be preceded.
