건설사업은 대형화, 복합화, 전문화되면서 목적물의 규모 및 범위가 점차 커지고 다수의 사업참여자가 수행하는 대규모 사업이 국내 외에서 지속적으로 발주되고 있다. 대규모 건설사업의 특성상 사업참여자들 간의 공정별, 분야별 간섭 및 충돌이 발생되면 해결을 위한 시간과 노력이 사업이 진행될수록 더 필요하다. 따라서, 본 연구에서는 인터페이스 해결을 위해 시간적, 물리적으로 유리한 설계단계의 인터페이스 관리방안에 대해 사례현장 적용내용을 바탕으로 제시하였다. 인터페이스 관리 협의체 구성, 체크리스트 도출, LIST 관리, PMIS 적용 등의 실제적인 관리방안을 통해 설계간섭 및 설계변경 관리 노하우가 필요한 타 현장에 적용하여 효과적인 사례로써 활용될 수 있을 것으로 기대된다.

The spiral case concrete (SCC) used in the underground powerhouse of large hydropower stations is complex, difficult to pour, and has high requirements for temperature control and crack prevention. In this study, based on the closed-loop control theory of "multi-source sensing, real analysis, and intelligent control", a new intelligent cooling control system (ICCS) suitable for the SCC is developed and is further applied to the Wudongde large-scale underground powerhouse. By employing the site monitoring data, numerical simulation, and field investigation, the temperature control quality of the SCC is evaluated. The results show that the target temperature control curve can be accurately tracked, and the temperature control indicators such as the maximum temperature can meet the design requirements by adopting the ICCS. Moreover, the numerical results and site investigation indicate that a safety factor of the spiral case structure was sure, and no cracking was found in the concrete blocks, by which the effectiveness of the system for improving the quality of temperature control of the SCC is verified. Finally, an intelligent cooling control procedure suitable for the SCC is proposed, which can provide a reference for improving the design and construction level for similar projects.

In the Urban Regeneration Project, the scale becomes huge and the composition of participating organizations is complex. It is necessary to establish the master plan fast and effectively harmonize conflict options and interests in the early stage of the project. However, the master planner, who is tasked to establish the master plan, and the master planning team, are difficult to establish the master plan fast while effectively considering various and complex information related to regeneration. The Urban Regeneration Project is composed of various types of computer files like HWP, EXL, PDF, DWG and others. When the master plan is established, it is necessary to link the information items and physical files of urban generation in order to effectively save the files in storage for easy search and utilization. This study developed a prototype system to support participating subjects of the Urban Regeneration Projects. It will effectively utilize the information items in the physical computer files using information blocks and Metadata. The developed system provides the base to effectively manage large amount of documents in the early stage of the Urban Regeneration Project and make effective decision-making using the concept of data warehouse.

As construction projects have been getting larger and more complex, a single individual or organization cannot have complete knowledge or the abilities to handle all matters. Collaborative practices among heterogeneous individuals, which are temporarily congregated to carry out a project, are required in order to accomplish project objectives. These organizational knowledge creation processes of project teams should be understood from the active and dynamic viewpoint of how they create information and knowledge rather than from the passive and static input-process-output sequence. To this end, agent-based modeling and simulation which is built from the ground-up perspective can provide the most appropriate way to systematically investigate them. In this paper, agent-based modeling and simulation as a research method and a medium for representing theory is introduced. To illustrate, an agent-based simulation of the evolution of collaboration in large-scale project teams from a game theory and social network perspective is presented.

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.

With the advances in the high-tech knowledge and service industries, along with a high-flying economy, the industrial structures of many cities have changed. The subject of the successful cases of dimensional integrated complexes in Roppongi Hills, the actions and preferences of these complexes'users were surveyed and analyzed in this study to determine the factors that contribute to the success or failure of such development projects. The results of the survey that was conducted in this study regarding the satisfaction of the residents of Roppongi Hills with such complexes will be considered in the formulation of a construction plan and will be used as base data for designing a large-scale dimensional integrated complex in Korea.

As interest for visualization and real time processing of construction management information was heightened recently, a diversity of management tools have been developed and corresponding systems also have been changed. In the case of BIM(Building Information Modeling) which is being spotlighted as such kind of management tool, its outcome such as technical innovation and time saving through overseas success case, reducing effect of unnecessary work, and so forth has continuously been established. The BIM in which various information related with life cycle of project are managed with the base of 3D object is useful as an information management tool of construction project which becomes complex and large in its scale. The aim of this paper is analysis or reliability on BIM design for expressway. To solve these issues, this study analyzes the design document, road design handbook, guide. Also this paper performed analysis of reliability 2D vs. BIM quantity calculation. This pilot projects "BIM design at Daegu expressway Lot No.5" lays the foundation for future work on BIM based civil engineering design.

최근 공사규모의 대형화, 복잡화 등으로 토목, 건축, 기계 등의 복합공종으로 구성된 공사들은 공기절감을 위해 패스트트랙(Fast Track) 방식으로 진행되는 사례가 많으며, 패스트트랙 방식에서는 적정 단계구분이 전체 프로젝트의 공기 책정에 중요한 사안이다. 본 연구에서는 복합공종으로 구성된 건설공사가 패스트트랙으로 진행될 때 적용할 수 있는 단계구분 방식을 제시하고 있다. 이를 위해 연구에서는 토목, 건축공사로 구성된 4개의 축구전용경기장 공사를 적용 사례로 분석하여 세분화된 공정분류체계(Work Breakdown Structure, WBS)를 통해 주요 단계별 공정 구분에 의한 일정표를 분석하고, 5가지 시안을 적용하여 패스트트랙 단계구분의 적정성을 분석한다. 분석된 시안중에서 최소 공기를 갖는 시안에 대하여 패스트트랙 단계구분 및 단계별 주요 공정의 구성 모형을 제시하였다. 이러한 방법론은 패스트트랙이 적용되는 유사한 규모의 대형 복합공사에서 패스트트랙 적용 시에 적정 단계 구분과 단계별 공정 구성 체계에 활용성을 가질 수 있다.

Currently, the way of providing housing in Korea has been regarded as public rental housing through large-scale development by the government. However, there is an increasing need for qualitative growth not only in quantitative growth but also in policies, systems, and sustainable design. The purpose of this study is to explore the applicable methods for domestic social housing through the policy and design guideline study of UK social housing which has achieved qualitative growth through diversification of development subject. First, the concept of social housing in the UK and sustainable housing design elements will be examined. Second, the characteristics and policy direction, project background, management and sustainability of five social housing projects over the last 10 years in the UK will be analyzed. In conclusion, in order to achieve the sustainable design of social housing, the construction of the social housing in terms of policy and environment must include safe and eco-friendly design adaptability that can secure local identity and respond flexibly to social change. In addition, the social housing in the UK, which forms a sustainable complex through cooperation between the public and the private sector based on its place and history, can be a guideline for establishing policies and design guidelines in terms of urban regeneration.
