The M/E/P (Mechanical, Electrical, and Plumbing) system of the building project has become more and more complex as the demand of the better living environment within the modern buildings increases. However, since the complexity and uniqueness involved within MEP trades, various fields of designers or contractors can hardly share their information with each other. This study employs BIM (Building Information Modeling) technology to assist the stakeholders of the construction projects to share and exchange information according to their needs. First, the process of different MEP disciplines will be systematically analyzed. Then the possible conflicts between trades will be identified. According to the study, necessary and important attributes required for the MEP BIM objects will be developed. Those developed BIM objects will later serve as the core of the communication platform, on which the project participants can easily access and share information. In addition, a better information integration mechanism for MEP systems will be developed throughout different phases of the project life cycle.
