Abstract：
During electromechanical construction, information model could be used for collision inspection, pipeline combination, workload statistic, prefabricated component process, system balance verification and construction schedule simulation, etc. Electromechanical installation work of Guangzhou International Sports Arena involves four disciplines, including ventilation and air conditioning, water supply and drainage, building electricity and intelligent building. BIM technique is adopted to successfully realize not only 3D collision inspection function, but also 4D simulation, which could be used for 4D construction schedule management, material management, virtual construction indication, cost management and equipment operation and maintenance management. This technique not only improves construction efficiency, but also optimizes the management efficiency and flow and realizes refined management.
