건축 기획단계는 프로젝트 전반에 걸친 주요한 의사결정이 일어나는 부분으로 그 영향력에 비해 프로젝트 정보를 수집, 처리, 저장하여 관련 참여자가 정보를 재사용하거나 참고하여 새로운 의사결정을 수행하는 것이 미흡하다. 따라서 본 논문에서는 BIM을 활용하여 기획단계에서 발생한 정보들이 설계, 시공, 유지관리 단계에 이르기까지 전생애주기에 걸쳐 정보를 통합 관리할 수 있도록 BIM기반의 건축 기획단계 지원 시스템을 개발하고자한다. 선행연구 분석과 이론적 고찰을 통해 건축 기획단계를 정의하고 건축기획 BIM의 개념과 특징을 도출하였다. 이를 토대로 기획단계 BIM프로세스를 정립하여 BIM을 기반으로 건축 기획단계를 지원하는 프로토타입 시스템 VA-Cityplanner를 개발하였다.

The planning stage of an architectural project has much more significant effects on the cost or outcome of the project than other stages of the project. In addition, the importance of architectural planning has been further increasing according to the recent trend of construction projects becoming larger in scale and more complex. In spite of this, the current situation is that the planning stage work is not being systematically managed. Accordingly, the purpose of this study was to develop a BIM-based simulation system for providing support during architectural planning stage such as spatial planning & review, cost review, project owner requirements management, etc. It is easy to review various alternatives using this system that allows not only the modeling of space object modeling but also the instantaneous review of spatial area & layout, cost, etc. based on object information. In addition, it can be used as a communication tool with the project owner as it provides the visualized information and quantitative data of the building model, and the information created through this system can be delivered to the following stage for usage. It is thought that using this system, the entire project work including the architectural planning stage can be supported and even contributing to the advancement of architectural process.

Recently, the architecture remodeling is rising as new alternative for activating the construction market as the interest toward life cycle of buildings has increased. But the reality is that current remodeling business is suffering various types of difficulties in its performance due to the absence of general management technology and factor technology in systematic performance procedure or evaluation, etc toward remodeling effect, evaluation on performance, imperfect system for reflecting user requirements and remodeling life cycle ; planning, $feasibility ^{\circ}\hat{E}designing^{\circ}\hat{E}construction^{\circ}\hat{E}management$ along with lack of overall understanding on remodeling. Accordingly, this research has attempted to search for an effective management method through overall understanding in project performance by presenting work procedure of remodeling project and analysis items for decision making, etc centered on early planning stage out of three stages called planning, designing and construction.

지능형 건물을 건축하기 위해서는 제일 우선으로 해야할 일이 기획을 하는 일이다. 이 첫단계가 건물의 특성을 결정짓는 가장 중요한 시작으로 첫 시작의 단추를 어떻게 꿰는가에 작업인 것이다. 기초를 잘 갖춘 학생이나 운동선수가 실전에 우수한 성질을 내는 것과 마찬가지로 건물도 초기 기획과 설계단계에서 과학적인 검토로 이루어져야 훌륭한 건물이 지어질 수 있다.

In this research, we studied an estimating method in client's sight to estimate the total construction cost which is based on the historical cost data at the early stage of the office buildings as a public phase. It is very difficult to analyze the estimation accurately and logically. When a client estimates a project, he/she has to consider there are many issues at the planning step, according as office buildings become gradually diversified as well as their roles continuously extended. Therefore, those are usually make problems for wasting the budget in accordance with the cost estimation errors. Moreover, many kinds of public construction projects, especially such as school, office, sports complex, and the others, have been invested the private finances defined as BTL(Build Transfer Lease) method that are required to manage the detailed process more strictly from initial planning. In order to make an effective planning, the long-term users amount and the building life cycle at the beginning of project should be considered previously and then it may enable to achieve an appropriate project plan. But actually considering overall variables in a building planning is impossible. Accordingly, suggesting a regression model based on the historical cost data from many similar types of office building to support client's role known as estimating the total cost at the early stage. And then performing the test against the proposed model to research the reasonability as using the historical cost data of Japan office buildings.

The purpose of this study is to apply the process model of the pre-design stage to CPLM(Construction Project Life-cycle Management). Life-cycle consists of 4 stage; Pre-design, Design, Construction, Maintenance. Each stage has organic relations between front and rear stage. Therefore it is important to manage and use the information data of each stage. But these data are not carried to the next stage smoothly, especially at the pre-design stage. It is even vague to define the process of the pre-design stage. To carry and share the information well, this study defines Pre-design stage process and CPLM at first, VA-Cityplanner which is the development system of the pre-design process model is applied to CPLM for the smooth current of the data between participants.

Due to the characteristics of 3D objects of building construction projects which have regular, vertical and repetitive shapes, the most practical utilization of BIM in the country is focused on building projects. The characteristics of 3D objects of civil engineering project have irregular, horizontal and non-repetitive shapes. Therefore, consisting of a practical BIM model is difficult comparing with building project. This study suggests an application process of BIM for the planning and design phases for civil engineering project. A BIM system is developed based on suggested BIM process and it is verified through a bridge construction project.

Recent advancement in ICT and IT infrastructure drives the construction industry towards a IT-based industry. Accordingly, the importance of the planning phase of a project is significantly highlighted due to recent large-scale national development projects such as U-city and multifunctional administration city. various development and studies are conducted on the convergence of 3D CAD and GIS in order to support the decision making by simulation of each phase of construction prior to the actual construction of a building. However there has been limits to the implementation of the IT technology in the planning phase due to its characteristics such as high reliability on the experts knowledge and the compliance of the administration work. In this study, a trendy issue of the convergence of the GIS technology with the 3D CAD design data is suggested to improve the efficiency of a decision support in the planning phase.

우리회는 한국기술사회건축구조분회로 출발하여 2년 전 유병억 회장님시절 개인사업자등록증을 발급받아 구조분회가 아닌 개인 사업체로서 한걸음 진일보하였다가 작년에야 비로서 우리의 숙원이었던 과학기술부 산하 사단법인체로 등록되면서 명실공히 사단법인 한국건축구조기술사회로 위상을 한단계 격상함으로서 합법적으로 정부로부터 인가받은 단체로 발돋음하였다. 그동안 건축구조안전에 대한 문제점을 알고 있었으나, 정부와의 어떠한 합법적이고 독립적인 통로가 없어 제대로된 의견개진을 할 수 없었던 상황에서 이제는 올바른 통로를 확보한 첫 걸음이라고 판단된다. 아직도 우리가 헤쳐나아가야 할 길은 멀고도 험난한 상황임을 잊지말고 끈기있는 인내심과 중단없는 전진을 통해 하나씩 건축물의 구조안전을 확보하기 위한 방안을 위해 지속적으로 노력을 하였으면 한다. 올해 2월 정기총회를 통해 사단법인으로 처음 출발하면서 이동헌회장님을 비롯한 신임회장단이 선출되었고, 그 장도의 첫발을 내딛으면서 앞으로 우리가 어떤 목표를 견지하여야 할 것인가에 대해 의식고취 및 앞으로의 방향설정을 위해 지난해 3월 건설교통부에서 발족한 건설교통안전기획단의 검토 내용에서 발췌한 현행 실태와 문제점 및 대책 중에서 건축물의 구조안전과 관련된 문제점을 다시 한번 되새기면서 우리의 목표와 방향을 점검하는 계기가 되었으면 한다.
