Approach of establishing As-Is BIM Model Process in Apartment Remodeling project using 3D Laser Scanning.

공동주택 리모델링 사업에서 3D 레이저스캐닝 기술을 활용한 기존 구조체 As-Is BIM모델 구축 프로세스 제안

More than 50% of the existing buildings in Korea are over 15 years old. Therefore it is necessary to be held reconstruction or remodeling deteriorated buildings more efficiently. Especially, since remodeling project reserves existing structures, it requires less period of project and construction period compare to reconstruction. It is possible to minimize uncertainty in communication between participants and able to manage information and construct efficiently in remodeling projects. This paper is first step of integrated BIM-based whole lifecyle management of apartment remodeling process. It suggests 3D laser scanner specification factors and site constraint factors for mapping between two groups. Therefore it will contribute to develop mapping algorithm of two groups and find optimal combination for apartment remodeling.
