Using Building Information Modeling to Improve the Mechanical, Electrical, and Plumbing Coordination Process for Buildings

Abstract

The coordination of mechanical, electrical, and plumbing (MEP) systems has become a major challenge for building contractors. Specialty design firms and trade contractors, working independently, provide these systems. The coordination of these systems involves locating equipment and routing Heating, Ventilating, and Air-Conditioning (HVAC) duct, pipe, and electrical raceway in a manner that satisfies many different types of constraints. For the past several years MEP coordination has involved sequentially comparing and overlaying drawings from multiple trades, in which representatives from each MEP trade work together to detect, and eliminate spatial and functional interferences between MEP systems. This multi-discipline effort is time-consuming and expensive. With the recent development of Building Information Modeling (BIM) this process is now able to evolve with the software technology. Using examples from several case studies, this paper demonstrates how BIM can improve the MEP coordination process in buildings. The results of this research provide a foundation for a revised work process utilizing modeling software and information technology.
