Case Study of the Field-BIM for Precision Construction of Elevator Core Wall in Top-down Project

Top-down 공법 현장에서 엘리베이터 코어월 정밀 시공을 위한 시공 BIM의 적용 사례 연구

Top-down construction is a useful method of utilizing the working space, economic benefits and shorten the construction period. Precision construction of the elevator core is very important for safety of the top-down structure. In this study, the layout system for the field-BIM(Building Information Modeling) was used to precisely construct the elevator core in the basement and the ground. Through the layout system, it was possible to process the construction status, review the design results and construction errors, and confirm whether there is or not within the construction error range for elevator installation.
