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.

The maintenance cost is rapidly increasing due to the increased of infrastructures such as railway and port etc., it is necessary management method of facility for measures and extend life. In the case of international infrastructure, in order to asset management to reasonably and effectively, asset management systems were developed for the management of facilities in various countries such as Australia and Canada etc. In this study, to develop the asset management process, the question investigation was conducted on maintenance site personnels for maintenance of the steel structure.
