Abstract:The production resource utilization efficiency, less environmental pollution, reliable quality of the construction industry is the future trend of the development of construction industry. Aiming at the problems existing in the construction industry in our country, put forward the combined BIM technology and 3D technology form BIM-3D technology system. However, BIM technology and 3D technology in the construction industry in our country at the primary stage, not form a scientific management system and management concept. Based on BIM technology and 3D technology application in the field of construction are analyzed. On this basis, it puts forward the model of BIM-3D technology, and analyzes the BIM-3D theoretical basis and key technology of 3D technology; Expounds the model application platform, and has carried on the detailed; Finally, analyzed the advantages and disadvantages of BIM-3D technology, so as to promote the rapid development of construction industry of China.
