This project applies the BIM 5D technology, and takes the BIM platform as the core. All specialized models, including civil engineering, mechatronic engineering, steel structure and curtain wall, are integrated on the platform, which, as a carrier, correlates with various construction information of progress, contract, cost, quality, safety, material, etc. The instinct visualized and computable characteristics of BIM models provide valid data supports for the project progress, cost control and material management. The application of BIM technology in this project is mainly during the construction stage, including field simulation, scheme simulation, visualization technical disclosure, construction simulation, schedule checking, material quantity extraction, contract programming, three costs comparison, progress quantity extraction, quality and safety management, etc. These applications have assisted managers in effective decision and precision management in the whole construction management process, so as to achieve the purposes of reducing change of construction project, shortening time, controlling cost, improving the quality.
