SYSTEM AND METHOD FOR AUTOMATICALLY CALCULATING QUANTITY AND CONSTRUCTION COST OF RAILWAY FACILITIES BASED ON BUILDING INFORMATION MODELING

Provided are a system and method for automatically calculating a quantity and construction cost of building information modeling (BIM)-based railway facilities through which a quantity and construction cost of BIM-based railway facilities are easily and readily calculated through automatic mapping between BIM object attribute information based on standard classification system information and object breakdown structure (OBS) attribute information/work breakdown structure (WBS) attribute information in the case of BIM design of railway facilities, a quantity and construction cost are automatically or manually input in connection with OBS code-specific itemized unit costs or a quantity and construction cost are manually input to a WBS code so that a quantity and construction cost of railway facilities can be calculated using BIM on items and processes that are not modeled as BIM objects of railway facilities, and completion and a progress rate are managed on the basis of a BIM statement by comparatively examining the BIM statement with an existing statement to automatically and connectively calculate a quantity and construction cost of BIM-based railway facilities.
