This study explores the issue of program management consortia involving multinational participants. The aim of this research was to leverage advantages in program management (PM) skills and PM model improvement in product line construction in mega scale construction programs, typically funded by public funds. Such ventures involve multinational parties using dedicated partnering based on a program management consortium (PMC) to reduce confrontation between parties in complex circumstances, allowing an open and non-adversarial approach to project management. This research also seeks to implement an ongoing feedback program of best practices and lessons learned to minimize the repetition of mistakes and to reduce costs in sequenced construction. Recently, the Korean government has planned to undertake three large new projects: the Korean Peninsula major river maintenance, the reclamation of Se-Mangum, and the Science/Business City. This paper starts by providing a framework for the cost-reduction strategy for the United States Forces Korea (USFK) Relocation Program, which will be funded with public funds and a private fund investment (PFI) that combines programs executed by two governments as owners and multinational stakeholders, joined in the PMC. The establishment of project-oriented consortia is an innovative and non-adversarial approach to massive international construction projects. Such projects have used various tools effectively and skillfully. This experience may offer an opportunity to practice new and advanced program management delivery methods, and it is expected that Korea will gain a competitive advantage in the international construction market.

Many conventional management methods have emphasized the minimization of required resources along the supply chain. Accordingly, this paper presents a proposed method called the Virtual Design and Construction (VDC)-aided system. It is based on object-oriented resource control, in order to accomplish a feed-forward control monitoring supply chain logistics. The system is supported by two main parts: (1) IT-based Technologies; and (2) VDC Models. They enable the system to convey proactive information from the detection technology to its linked visualization. The paper includes a field study as the system's pre-test: the Scaffolding Works in a LNG Mega Project. The study demonstrates a system of real-time productivity monitoring by use of the RFIDbased Mobile Information Hub. The on-line 'productivity dashboard' provides an opportunity to display the continuing processes for each work-package. This research project offers the observed opportunities created by the developed system. Future work will entail research experiments aimed towards system validation.

오늘날 건설수요는 고도화, 프로젝트의 대형화, 공사여건의 복잡화와 같은 외부환경에 의해 변하고 있다. 이에 정부에서는 외부환경의 변화에 적절히 대응하고자 선진화된 발주방식을 도입하였다. 그러나 이러한 의도와는 달리, 기 발주된 프로젝트에서는 발주방식별 장${\cdot}$단점 등이 효과적으로 나타나지 못하고 있다. 이러한 원인은 사업의 기획단계에서 발주방식을 선정할 때 사업의 특성을 충분히 반영하지 못하는 현재의 "대형공사 입찰방법 심의기준"에서 그 원인을 찾을 수 있다. 따라서 본 연구는 프로젝트의 특성에 따른 적절한 발주방식을 적용하기 위하여 발주방식 선정기준을 위한 모델을 제시하고자 한다.

안전하지 못한 환경은 작업속도를 지연시키고, 사고 발생 시 대응에 많은 시간을 소요하게 하여 건설공사의 생산성을 크게 저하시킨다. 반면, 지나친 안전관리를 오히려 생산성 저해 요인으로 지적하는 연구도 존재한다. 따라서 건설공사의 생산성을 저해하지 않는 적절한 안전관리는 성공적 공사 수행에 매우 중요한 요인이나, 안전관리와 생산성 상호 간 미치는 영향이 복잡하기에 이에 대한 연구가 부족한 실정이다. 이에 본 연구는 시스템 다이내믹스를 활용하여 안전 관리와 생산성 영향 요인 간의 인과 모델을 구축하고, 효율성 지표를 통한 생산성 측정 및 분석을 진행한다. 이를 통해 과다 인원 투입으로 인한 현장 혼잡도 증가, 비정기적 안전 조치 및 비효율적 초과근무가 실제 작업에 투입되는 시간에 미치는 영향을 분석한다. 안전관리와 생산성의 상호 영향성에 대한 기초 연구인 본 연구의 결과물은, 적정 생산성 확보 가능한 안전관리 방안 수립의 기반으로서 건설산업 경쟁력 제고에 기여할 수 있을 것으로 기대한다.

As the needs for the mega-sized, high-rise and irregular shape of building increase, domestic application of BIM in construction industry is increasing in recent years. In this circumstance, interests in BIM modeling and modeling detail level have been also increased. BIM that is based on a three-dimensions, requires a specific and precise building expressions. And model expression level required for each phase such as design, construction, and maintenance of the construction project could be different as its needs. Because that it is not clear to define the criteria for the expression level of construction BIM model, It is difficult to decide how detail and what to model is appropriate in the practical application of BIM model. It could be the reason why the productivity in construction project became lower and lower. In this study we consider the way how to improve the productivity of BIM and analyze the appropriate representation level of construction BIM model through the experts' survey. The results of study could suggest the basis for an appropriate expression level of construction BIM model.

The construction industry can be described as one of the most volatile industry depending on the situation. As such, a contractor, who is usually positioned to take all kinds of risk, may frequently require to form a strategic partnership for better execution of a project. In this study, we are going to review act or behavior that may happen among such partnership. For such review, a survey targeted at domestic construction companies has been conducted on their thoughts as regards opportunism, risk perception, and the contractual governance between partners. The analysis result of structural equation and regression has indicated that there exists a positive effect on the opportunistic behavior from the risk perception, a moderating effect on contractual governance between the performance risk and opportunism, whereas no such moderating effect on the same between relational risk and the opportunism. The output of this study may assist various domestic individuals who wish to participate large scaled overseas projects.

This paper outlines the current steel design climate and describes some recent and unusual designs using structural steel or composite steel and concrete which have been carried out in Hong Kong and the East Asia region. Composite structural systems for very tall buildings are outlined. A case study of concept designs for one of these is presented. Two further case studies are presented: a refurbishment project where the use of steel and innovative strengthening techniques allowed an additional five stories to be built on an existing reinforced concrete frame and a monumental sculpture.

This paper addresses the key technologies for supertall building construction based on the Lotte World Tower project in Korea. First, the mega-mat foundation construction technologies are shown, including ultra-low heat concrete, heat of hydration control programs, and the logistics plan. Then, high strength concrete technologies of 50~80 MPa are introduced and discussed within the context of the highest pumping record in Korea at 514.25 meters. Structural design concepts of gravity load and lateral force resistance systems are introduced, along with surveying systems using GNSS and temporary installation plans of special heavy equipment like tower cranes, hoists, and high pressure concrete pumps. If it is possible to coordinate these key technologies and others, optimizing for the building's design and construction, supertall building construction can be successfully completed.

This paper examine the changing ecosystems in Malaysia, starting with the government policy driven greenfield cluster of Cyberjaya, which is part of the Multimedia Super Corridor (MSC) mega project. In this context of an emerging economy, predominantly production oriented, the role of the government was crucial with respect to implementing policies and building infrastructure for the ecosystems. First, the roles played by the cluster development agency, universities, and industry are explained. As the cluster developed, this paper, taking an entrepreneurial ecosystem approach, explores how some actors evolved and changed their roles to become catalyst organisations established for the cluster now serving nationwide. This was followed by the emergence of new actors in the ecosystems, for example, knowledge intermediaries, and new roles for universities. In addition to actors such as universities and industry, this paper recognizes the emergence of media organisations as new actors in the entrepreneurial ecosystems in Malaysia.

최근 건설 산업은 IT기술의 발전과 함께 새로운 기류를 맞고 있다. 컴퓨터를 이용한 다양하고 신속한 정보 및 지식관리가 이루어지고 있으며 사용자간 의사소통도 활발하게 이루어지고 있다. 이미 시공단계의 정보들을 처리해 주는 PMIS와 사용자들의 업무 노하우를 공유하는 수단인 KMS와 같은 시스템이 현장에 적용 되어 활용되고 있고, 최근에는 전자매뉴얼(IETM)로 대변되어지는 생애주기 전반의 법, 행정 절차제공자에 관한 연구로 범위가 확장되고 있다. 그러나 도시재생사업과 같은 대규모 건설사업의 경우 사용주체와 용도에 따라 주요 기능이 역동적으로 변화되는데 이 역동성은 전자매뉴얼 고유의 역할을 제한하기도 하고 기존의 시스템들과 경계를 모호하게 하기도 한다. 이에 본 연구에서는 경력 실무자들을 대상으로한 설문과 인터뷰, 건설프로젝트의 특성 분석을 통하여 건설분야 전자매뉴얼이 갖추어야 할 요소들과 설계 전략을 규정하고 이를 토대로 도시재생사업의 적용예를 통해 법과 행정절차 제공자라는 개발취지에 적합한 전자매뉴얼 개념 모델을 제시한다.
