BIM을 활용한 VE/LCC/LCA 평가 모형 개발

Abstract

PURPOSES : This study aimed to provide a method for linking VE/LCC/LCA and BIM and to develop a system for BIM-based VE/LCC/ LCA evaluation. METHODS : Based on literature reviews and case studies, we propose bridge hierarchies for sharing and integrating VE/LCC/LCA and BIM information and standard unit price and equipment workloads for LCC and LCA analysis. We further developed a BIM library to visualize various ideas and alternatives. RESULTS : The results of the proposed system demonstrate that the VE can be systemized and the original draft and alternatives can be visually provided via the BIM library. In addition, the LCC cost can be calculated by the automatic volume calculation of the bridge BIM library and the LCA can be calculated using the materials and equipment (these are BIM attribute information). CONCLUSIONS : The developed method can be more reliable and productive of VE, LCC, and LCA work owing to the partial automation and visualization of the developed system.
