Case Study of Three-dimensional Optimization Design on Architectural MEP Based on BIM Xiaobiao Lv 1,a, Zijian Liang 1,b 1School of Civil Engineering and Architecture, Hubei University of Technology, Wuhan, Hubei, 430068, China alvxiaobiaohn@163.com, bhaijingyuanling@sina.com Keywords: MEP, BIM, Collision Detection, Optimization design Abstract.
BIM-based collaborative design could create a project file saved in various professional engineers were authorized to read and write files on the server, then created a central file which would be saved as a local file by different professional engineers.
Thus, different professional engineers for MEP could see both their structures and arrangement of things, collisions and errors could be discovered, might at any time a collision with other engineers to discuss.
