This paper is an attempt at developing a method for the analysis and estimation of the effects of project disruptions due to uncertainties. Such uncertainties may result from design changes in large-scale, complex, research and development, or construction projects. An entropical risk analysis method is developed. The method is able to estimate the project capacity to handle equivocation due to design changes and the effects of project disruptions. In an attempt to evaluate the predictive capability of the method, it is compared with the results obtained by a computer Monte Carlo simulation program. It is shown that the entropical risk analysis method may be suggested as an expedient means of evaluating project status for management in the different stages of project execution.

Recently, Information System (IS) development projects such as the next generation IS project of the financial business domain have shown tendency to become large and complex. Accordingly, a large number of enterprises have introduced a Project Management Office (PMO) to successfully manage multiple complex large-scaled projects. Many researches and empirical studies have proved the positive results of PMO-based projects. For example, most PMO-based projects have been accomplished successfully without exceeding the planned deadline and budget. However, even in the case of PMO-based projects, participants are still supported by legacy Project Management Systems (PMS) developed without considering the PMO. It implies that recent large projects are hardly performed efficiently because of the large gap between the legacy PMS tools developed only for single small projects and the real process of PMO-based project management. Therefore, we attempt to design and develop a PMO-based PMS in which the role and responsibility of PMO are completely implemented. To demonstrate our systems practicality, we applied the devised system to the real project management cases of "K" bank in The Republic of Korea. According to the results of case analysis, all of the four projects supported by our PMO-based PMS have been completed without exceeding planned deadline and budget, and the quality of their final outcome is appraised to be superior.

공동주택 리모델링 프로젝트의 성능개선과정은 일반적으로 프로젝트 의뢰단계, 기획 및 조사진단 단계, 설계단계, 시공단계의 4단계의 사업절차로 구분될 수 있다. 하지만 현재 국내 리모델링 사업은 각 단계별 의사결정 업무체계와 사업수행절차가 체계화 되어있지 못하여 사업수행시 설계자 관점의 종합적 관리계획 수립의 어려움 등 여러 가지 문제점을 겪고 있다. 그 중 리모델링 설계단계는 사업시행자, 설계자, 거주자, 엔지니어 등 사업 참여 주체의 역할 및 업무절차가 타 단계에 비해 매우 복잡하고 정형화되어 있지 못하여 사업에 대한 시행착오, 사업지연, 설계부실 등을 발생시키는 주요 단계로 볼 수 있다. 특히 설계단계에서 각 사업참여자별 발생되는 정보활용 능력에 대한 부족과 부적절한 의사결정으로 인한 설계도서의 부실은 시공단계에 각종 문제를 발생시킬 뿐만 아니라 궁극적으로 거주자가 원하는 리모델링 성능향상에 대한 만족과 신뢰를 어렵게 하고 있다. 따라서 리모델링 설계단계는 매우 주요한 관리대상 단계이며, 설계관리 기술과 함께 사업수행 프로세스에 관한 종합적 이해가 필요하다. 이를 위해 본 연구에서는 리모델링 설계단계를 대상으로 참여사업주체의 역할과 책임을 규정하고, 설계 프로세스 단계별 발생정보를 중심으로 정보활용 과정을 분석하고자 하였다. 본 연구의 정보활용은 발생정보(Input)와 활용기법(Tool) 및 결과물(Output)의 과정으로 분석하였으며, 이를 통해 설계단계별 의사결정 방법을 정립하고, 설계관리 전반의 사업수행 프로세스를 구축하고자 하였다.

The capability of design and engineering of global EPC companies has long been equalized through past similar construction experiences. Among various key factors in the success of EPC project, the capability of engineering is considered to be the most important factor since the engineering is preceding activities of EPC contract. The failure of engineering may adversely affect the subsequent procurement & construction activities and in turn may cause cost overrun or schedule delay. Therefore, an EPC company needs to continue to improve the engineering capabilities for the success of project. The engineering capabilities can be further improved if the EPC company should prevent recurrence of similar design faults that were previously committed. This study is intended to present how to make the most of the failure examples from previous projects towards a success of project. Failure is but a stepping stone to success. The EPC company can obtain useful lessons from the analysis of past failure examples.

국내에서 BIM의 실무 활용은 건축공사 중심으로 적용되고 있다. 건축공사의 부위별 객체 특성이 정형적, 수직적, 반복적인 형태를 갖는 반면에 토목공사의 객체 특성은 비정형적, 수평적, 비반복적인 형태를 갖으므로 3D객체 구성이 어렵기 때문이다. 본 연구에서는 토목공사의 기획단계부터 설계단계까지의 업무 및 정보관리의 문제점을 파악한 후 BIM기반에서의 적용 프로세스를 제안하며, 제시한 프로세스를 기반으로 BIM시스템을 구축하여 교량공사를 대상으로 실무 적용성을 검토한다.

Ethnography, a major research method in Anthropology, has been recently applied in human-centered design research. Since ethnography has empirical, naturalistic, holistic and eclectic characteristics, it is needed a guideline to apply ethnography into design research in accordance with a characteristic of project. Design project in which ethnography is applied can be categorized by two criteria; degree of newness of project goal(existing user-potential user) and limitedness of worksite(site-oriented-work-oriented). Among work-site activities, technology in use, and user group culture, it should be decided which content to content to focus more than others and thus what kinds of research techniques to apply in the ethnographic research.Case study was to design an interior of a Korean express train. This project is site-oriented and has an existing-potential users. Therefore, video ethnography was effectively applied to obtain chronological data of activity potential users. Therefore, video ethnography was effectively applied to obtain chronological data of activity flow, and participant observation was applied to obtain statistical data of synchronous activities. Case study shows a concrete process example of how to apply ethnography into design research.

This mixed-use Raffles City (RCH) development is located near the Qiantang River in Hangzhou, the capital of Zhejiang province, located southwest of Shanghai, China. The project incorporates retail, offices, housing, and hotel facilities and marks the site of a cultural landscape within the Quianjiang New Town Area. The project is composed of two 250-meter-tall twisting towers with a form of vibrant waves, along with a commercial podium and three stories of basement car parking. It reaches a height of 60 stories, presenting views both to and from the Qiantang River and West Lake areas, with a total floor area of almost 400,000 square meters. A composite moment frame plus concrete core structural system was adopted for the tower structures. Concrete filled steel tubular (CFT) columns together with steel reinforced concrete (SRC) beams form the outer moment frame of the towers' structure. The internal slabs and floor beams are of reinforced concrete. This paper presents the engineering design and construction of this highly complex project. Through comprehensive discussion and careful elaboration, some conclusions are reached, which serve as a reference guide for the design and construction of similar free-form, hybrid, mix-use buildings.
