Introduction of Construction Management Integrated System Using BIM in the Honam High-Speed RailwayLot No. 4-2

The Honam High-Speed Railway Lot No.4-2 consisting of 6 bridges including the arch bridge, the extra- dosed bridge and 2 tunnels with a total length of 9.38km and the whole construction work should be completed within 31 months only. In order to control the detailed cost and the construction process thoroughly, the construction management integrated system based on BIM(Building Information Modeling) has been developed and adopted firstly by the Civil Engineering Technology Dept. of Ssangyong E&C in Korea. In this paper, the application of the construction management integrated system using BIM on the Honam High-Speed Railway Lot No. 4-2 has been introduced. This system is mainly made up of the full-range 3D information models and the web-based 5D system models. The web-based 5D system is composed of the safety and equipment management modules using virtual reality as well as the 4D earthwork quantity control system. Through the construction management integrated system based on BIM, an integrated on-site management can be achieved, especially in the best cost adjustment, construction management and safety conditions.
