Mechanical, electrical and plumbing (MEP) refers to these aspects of building design and construction. In commercial buildings, these elements are often designed by a specialized engineering firm. MEP design is important for planning, decision making, accurate documentation, performance- and cost-estimation, construction, and operating/maintaining the resulting facilities
BIM is a modern engineering design approach, which goes beyond the use of conventional construction plans to represent and specify a project. Instead, BIM uses 3-dimensional building models with detailed information about system components, effectively creating a virtual reality version of the building before actual construction. BIM can be applied to all technical disciplines, including not only MEP systems but also architectural and structural aspects.
