Recently, CM at Risk delivery system(CM@R) that could solve the problems of Design Bid Build delivery(DBB) system has been emerging. In the CM@R delivery system, the contractor negotiates for a maximum guaranteed price(GMP) with the client at the design stage, and the contractor carries out the construction within the GMP. In CM @ R, the construction company with expertise in construction participates from the design stage to reflects the construction know-how in the design. On the other hand, the modification design frequently occurs due to the change of the construction cost when negotiating the GMP. In addition, uncertainties are inherent in the GMP calculation because the calculation is based on unfinished drawings and documents. This study proposes a probabilistic GMP estimation method applying MCS to the BIM - based cost prediction model, in order to extract the accurate quantity information when estimating the GMP and to cope with the change of the construction cost inherent in uncertainty.

본 논문은 스틸하우스 기법에 사용되는 스터드를 이용하여 건축자재인 스터드를 컴포넌트와 패턴으로 구성, 조립하여 패턴 단위로 건축설계가 효율적으로 이루어질 수 있도록 하는 가상 건축물 설계를 시뮬레이션 하였다. 또한 3ds Max를 이용하여 건축 분야에 설계, 분석, 변경정보, 조립 등의 건축설계를 시뮬레이션 하여 건축의 손쉬운 변경과 비용을 효과적으로 절감하기 위한 기술을 지원하는 가상 건축설계 기술을 제안한다. 특히 설계자와 사용자도 패턴을 이용하여 쉽게 건축물에 대한 외부 뿐 아니라 내부 구조도 변경시킬 수 있으며 변경에 따라 필요한 자재들의 패턴 정보와 변경된 건축물의 필요한 자재들이 자동 생성되도록 하였다.

In this study, the change of critical elements of the design evaluation was investigated during two decades at the architectural competition which was held nationwide in Germany. Specifically, the periods of investigation span both from July 1989 to June 1990 and from July 2009 to June 2010. The results of the analysis show that the cost of construction, the maintenance cost, the design of facade and the energy conservation are being magnified for the new important elements. The images of buildings and the economic aspects are meant to be high. The frequency of the critical elements for interior spaces is approximately two times more important than those for the forms and outdoor spaces. Overall, many juries of the architectural competition in Germany were interested in the elements for interior spaces. The field of function accounts for roughly the half of four basic architectural fields such as function, others, aesthetic and construction fields. The critical elements are required persistently such as context, Circulation, organization of space, form, landscape and outdoor space design, arrangement of building, cost of construction, function, design of facade, location of main entrance. These items are regarded as the most important elements of the design evaluation at the competition. Knowing the change of critical elements of the design evaluation, we can understand the trend of architecture in Germany. The results of this study can be applied in Korea to develop the critical elements of design.

In the case of relatively good ground and construction condition in the deep excavation for the construction of subway, railway, building etc., flexible earth retaining systems are often used in an economical point of view. It is generally known that the mechanism of behavior in the flexible earth retaining system is relatively more complicated than the rigid earth retaining system. Moreover in the case of long span strut supporting system the analysis of strut axial force change becomes more difficult when the differences of ground condition and excavation work progress on both sides of excavation section are added. When deeper excavation than the specification or installation delay of supporting system is done or change of ground condition is faced due to the construction conditions during construction process, lots of axial force can be induced in some struts and that can threaten the safety of construction. This paper introduces two examples of long span deep excavation where struts and rock bolts were used as a supporting system with flexible wall structure. And the sections of two examples are 50 meters apart in one construction site, they have almost similar design and construction conditions. The characteristics of ground deformation and strut axial force change were analysed, the similarity and difference between measurement results of tow examples were compared and investigated. The effort of this article aims to improve and develop the technique of design and construction in the coming projects having similar ground condition and supporting method.

The purpose of this study is to prevent dispute due to change orders in construction projects and to handle change orders smoothly. For this purpose, this study analyzed arbitration cases caused by change order handled by the Korea Commercial Arbitration Board. Based on this, dispute factors were analyzed and change order management factors and management plans were presented. Change order management factors were derived from responsibility, contract, design, process, construction cost, and schedule management, and a detailed management plan according to the relevant factor was presented.

Configuration Management (CM) is a process of identifying and documenting the characteristics of a Structures, Systems and Components (SSCs), and of ensuring that changes to these characteristics are properly assessed, approved, issued, implemented and verified. There are requirement management, change control, facility configuration information management for CM activities. In order to improve safety of Nuclear Power Plant(NPP), it is necessary to manage change item systematically. Existing CM concept is focused on the NPP in operation. On the other hand, NPP under construction is difficult to efficiently manage the change because of different change process from varoius stake-holders. This research considers method of consolidation change process for NPP to ensure that approved changes are accurately reflected in the design requirements, facility configuration information, and the physical configuration.

국제적으로 자유무역협정(FTA)에 따른 건설시장의 개방으로 인해 계약상의 권익 주장이 일반화되고 있으며 계약당사자들 간의 분쟁이 빈번히 발생하고 있다. 건설산업의 계약조건은 타 산업과는 다른 특수성을 지니므로 각 공사별로 공종, 환경, 주변 여건 등의 특성을 판단하여 별도의 계약 조건을 설정해야 한다. 국내에서도 공사규모의 증대와 복합기능의 요구에 따라 Design-Build의 발주가 확대되고 있으나 이에 적합한 계약규정이 정해져 있지 않고, 일반공사에서 사용되는 공사계약 일반조건의 일부규정에만 따르고 있어 설계변경 시 여러 가지 클레임 요인들이 발생하고 있는 실정이다. 건설시장 개방이라는 현안을 능동적이고 효과적으로 대처하기 위해서는 국제기준에 부합되는 설계변경 관련 건설 계약규정 및 제도 개선이 요구되므로, 본 연구에서는 이를 위한 객관적이며 합리적인 설계변경 클레임 발생요인의 유형분류와 분석을 통하여 정성적인 클레임요인들을 정량화시켜 D/B사업단계별 설계변경 관련 클레임의 주 요인에 대한 구체적인 분쟁 대응방안을 제시하였다.

As abnormal climate phenomena occur more frequently due to climate change, damage which results from meteorological disaster increases accordingly and its scale and variety are becoming wider. This paper draws out planning and design elements and application techniques to build cities more adaptive to climate change from urban development cases in US and Europe. An urban model is suggested, that enables built environment to be more resilient to risks caused by climate change is applicable to urban development projects in practice.
