Knowledge management (KM) is one of the useful management tools in today's project management (PM) practice, such as construction projects. Nobody can deny the importance of "useful knowledge" always helps organizations and project managers shaping a decision. Due to the trend of globalization, it is now very common that an organization may comprise employees from different countries of distinct national-cultures working together. It is also not uncommon that different projects, within an organization, may have their own organizational-cultures which influence its knowledge repository, transfer process and knowledge strategy. Therefore, it is extremely difficult to align all these cultures and consolidate them to benefit the KM process and PM practice. Organizations and project managers understand that different national-cultural and organizational-cultural factors will create impact on the philosophy of KM process which will subsequently affect PM practice. Those factors may affect interpersonal relations and exchange of knowledge between projects and amongst staff. Systematic KM process can utilize the goodness of different employees from distinct cultures which can eventually drive the organization and projects to success. The purpose of this paper, based upon a case study of a Hong Kong construction company, is to discuss how those cultural factors are linked to KM and what organization and project managers can do to improve the KM process and PM practice.

Effective communication flow is a fundamental for the success of any construction projects. The key role of communications among project parties is even more critical in the case of Design-Build (DB) projects. Previous research has shown that these projects have an environment where integration between different project team members and schedule constraints increase channels of communication, and require faster communication flows. This paper summarizes the findings from research analyzing organizational structures and communication flow of the Texas State Highway 130 (SH130) project. Awarded in 2002, the SH130 project, totaling $1.3 billion USD, constitutes the "pilot" application for the DB approach in the state of Texas. A set of observations pertaining to team organization and communication issues in the design-build environment is included.

In recent years, building commissioning has often been part of a standard delivery practice in construction, particularly in the high-performance green building market, to ensure the building is designed and constructed per owner's requirements. Commissioning, therefore, intends to provide quality assurance that buildings perform as intended by the design and often helps achieve energy savings. Commissioning, however, is not as widely adopted as its potential benefits are perceived. Owners are still skeptical of the cost-effectiveness claims by energy management and commissioning professionals. One of the issues in the current commissioning practice is that not every project is guaranteed to benefit from the commissioning services. This, coupled with its added cost, the commissioning service is not acquired with great acceptance and confidence by building owners. To overcome this issue, this paper presents a unique methodology to enhance owner's predicting capability of the degree of success of commissioning service using the Bayesian theorem. The paper analyzes a situation where a future building owner wants to use a pre-commissioning in an attempt to refine the success rate of the future commissioned building performance. The author proposes the Bayesian theorem based framework to improve the current commissioning practice where building owners are not given accurate information how much successful their projects are going to be in terms of energy savings from the commissioning service. What should be provided to the building owners who consider their buildings to be commissioned is that they need some indicators how likely their projects benefit from the commissioning process. Based on this, the owners can make better informed decisions whether or not they acquire a commissioning service.

BAT 공장 건설 프로젝트는 외국 발주자에게 한국 CM업체의 관리능력을 입증한 대표적인 프로젝트라고 한 수 있다. 본 프로젝트는 CM 사의 전문적인 관리를 통하여 외국의 공장건설에 비하여 $15\%$ 절감된 금액으로 공사를 완공할 수 있었으며, 철저한 공정관리로 공기를 단축하는 한편 준공 후 1개월도 안되어 생산이 이루어지는 성공적인 결과를 달성할 수 있었다. 본 프로젝트의 성공요인(Key Success Factors)은 CM사의 탁월한 관리능력이라고 할 수 있으나 더욱 중요한 성공요인은 사업관리의 모든 권한을 CM사에 위임하는 발주자의 신뢰에서 기인되었다고 할 수 있다. 본 연구는 "One Stop Shop" 개념의 CM 적용을 통하여 사업의 전단계에 걸친 전문적인 관리활동과 발주자와 CM사간의 신뢰의 중요성을 입증한 프로젝트에 적용된 Cost Management, Contract Management, Value Engineering 등의 활동을 고찰하였다. 본 연구를 통하여 민간시장의 CM활성화에 비하여 적용에 어려움을 주고 있는 공공시장에도 CM이 활성화 될 수 있는 계기를 되기를 바란다.

The limited public funds available for infrastructure projects have led governments to consider private entities' participation in long-term contracts for finance, construction, and operation of these projects to share risks and rewards between the public and the private. Because these projects have complicated risk evolutions, diverse contractual forms for each project member to hedge risks involved in a project are necessary. In light of this, Build-Operate-Transfer(BOT) model is considered as effective to accomplish Public Private Partnerships(PPPs) with a characteristic of an ownership-reversion. In BOT projects, the government has used such an incentive system as minimum revenue guarantee(MRG) agreement to attract the private's participation. Although this agreement turns out critical in success of BOT project, there still exist problematic issues in a financial feasibility analysis since the traditional capital budgeting theory, Net Present Value(NPV) analysis, has failed to evaluate the contingent characteristic of MRG agreement. The purpose of this research is to develop real option model based on option pricing theory so as to provide a theoretical framework in valuing MRG agreement in BOT projects. To understand the applicability of the model, the model is applied to the example of the BOT toll road project and the results are compared with that by NPV analysis. Finally, we found that the impact of the MRG agreement is significant on the project value. Hence, the real option model can help the government establish better BOT policies and the developer make appropriate bidding strategies.

Project manager plays a very important role in the success of any project. The primary duty of the project manager is to combine the outcomes or results of the various processes and activities of project management into a systematic project management strategy or plan for the project. In the construction industry, a lack of motivation is an urgent problem for many project managers in construction and engineering projects. Lack of motivation affects the quality and productivity of jobs, reducing profits and growth for companies, businesses, contractors or organizations that rely on human resources. The reasons for this lack of motivation are diverse ranging from salary to culture to life and working environment, among others. Through surveys and data analysis using Cronbach's Alpha reliability and EFA (Exploratory Factor Analysis), our research scaled the factors affecting work motivation of project managers in the construction industry in Vietnam. The research results identified six major groups of relevant factors including (i) salary and benefits, (ii) work environment, (iii) promotion opportunities, (iv) organizational culture, (v) interest in the job, and (vi) relationship with the organization. From there, this paper contributed useful information as well as measures for businesses, companies, contractors or organizations in the construction industry.

Although the evolution and deployment of information technologies will undoubtedly play an important role in the current construction industry, many engineers are still unsure of the economic value of using these technologies. Especially for the planning of a construction project, a collaboration system to utilize the whole resources is a essential tool for the successful outcome. A detailed, authoritative, and readily accessible information model is needed to enable engineers to make cost-effective decisions among established and innovative plan alternatives. Most engineers rely on limited private experiences when they create solutions or design alternatives. Initial planning is crucial for the success of the construction project. Most construction projects are done through collaboration of engineers who have different specialized knowledge. Information technologies can dramatically enhance the performance of the collaboration. For the information delivery, we need a mediator between engineers. Object-based 3-D models are useful for the communication and decision assistance for the intelligent project design. In this paper, basic guidelines for the 3-D design according to different construction processes are suggested. Adequate interoperability of 3-D objects from any CAD system is essential for the collaboration. Basic architectures of geometry models and their information layer were established to enable interoperability for design checks, estimation and simulation. A typical international project for roadway was chosen for the pilot project. 3-D GIS model was created and bridge information models were created considering several requirements for planning and decision making of the project. From the pilot test, the integrated construction project planning using 3-D information models was discussed and several guidelines were suggested.

Since 'Act on Private Participation in Infrastructure' were changed in January 2005, BTL(Build-Transfer-Lease) projects of Private Participation in Infrastructure was introduced in the domestic construction market for the purpose of providing public facilities with the public. Selecting the most qualified Promoter should be considered discreetly in BTL projects because BTL projects is for projects with approximately thirty year project life cycle, plan, construction, operating, maintenance and obviously the success of the project totally depends on the capability and role of Promoter. However, score for cost is likely to influence selecting Promoter to take the project. Accordingly, low bid contract with too much competition could decrease the quality of the construction plan and operating plan. Thus, this study did preliminary research and documents on problems of evaluation criteria for selecting Promoter in BTL projects, and proposed improvement factors by doing questionnaire over specialists of each field.

IT발전의 따른 산업분야의 정보시스템은 기업 또는 프로젝트의 생산성 향상과 전략적 경쟁우위를 점하게 하는 필수적 지원도구 중 하나로 인식되고 있다. 이러한 정보시스템의 효과를 극대화하기 위해서는 정보시스템의 성과에 영향을 미치는 성공요인들을 규명하는 과정이 필요하다. 왜냐하면, 이러한 성공요인을 활용하여 IS의 성과달성 또는 성공여부를 예측하거나 또는 성공에 이르는 메커니즘을 규명할 수 있기 때문이다. 하지만, 우리나라에서 건설프로젝트 참여자의 의사가 반영된 웹 기반 PMIS의 성공모델에 대한 연구는 미흡한 실정이며, 따라서 웹 기반 PMIS의 성과달성 또는 성공 메커니즘 역시 아직 규명되지 않은 상태이다. 따라서 본 연구의 목적은 기존 연구에서 널리 활용되고 있는 DeLone and McLean의 수정된 IS 성공모델[5]에 근거하여, 웹 기반 PMIS가 국내 건설프로젝트에서 국내 건설기술자에 의해 활용되는 상황에서, 웹 기반 PMIS의 성공요인이 사용자 사용의도와 만족도 어떠한 영향을 미치는가를 분석하는 것이다. 분석을 위한 건설 PMIS의 성공요인은 연구자의 선행연구에서 타당성 및 신뢰성이 검증된 을 항목을 활용하였으며. 건설 PMIS의 성공변수는 사용의도 및 사용자 만족도로 설정하여 기존 정보시스템 성공모델에 관한 문헌고찰을 통해 평가항목을 구성하였다. 실제 PMIS의 사용자인 시공사, 사업관리자를 대상으로 설문조사를 실시하였으며 이렇게 수집된 자료들로 통계프로그램인 SPSS 12.0을 활용하여 다중회귀분석을 통해 건설 사업에서 웹기반 PMIS의 성공요인과 사용의도, 사용자 만족도간의 영향관계를 분석하고 시사점을 도출하였다. 이 연구에서 제시하는 웹 기반 PMIS 성공모델을 통해 검증된 성공요인은 시스템 평가와 성공 예측 등에 활용 가능하며, 연구 결과 제시되는 시사점들은 향후 보다 설명력 높은 성공모델 구축의 방향 설정에 기여할 것이다.
