The mechanical,electrical and plumbing（MEP）in the artificial island of Hong Kong-Zhuhai-Macao Bridge have many types and large number,meanwhile the net height requirements are strict and the project construction period is short.We apply Revit software to deepen the design of MEP of this project,establish the professional BIM models.Through the design process such as model linking,collision checking and pipeline adjustment,we draw the nodes plan,section and 3D drawings with BIM characteristics.By deepening the design work,it satisfies the requirements of the net height,improves the aesthetics of the MEP layout,reduces the number of design changes,and promotes the project to be successfully completed on schedule and by quality.
