BIM makes it possible to fully model all the components within a building, according to an article from Building Operating Management on the FacilitiesNet website.

This is especially crucial in healthcare settings where overhead space is often limited and there are myriad services vying for space, all of which have their own maintenance needs and clearance requirements that must be coordinated for an effective installation.

Design teams can accurately model above-ceiling conditions and coordinate the installation space and clearance requirements for the various services. This information can then be communicated to the construction team through a coordinated construction model.

The construction team can refine the modeling with the equipment to be installed for a particular project and work with the design team to refine the model so that installation drawings for the various trades can be produced for use in the field by installers. The entire effort can occur before fabrication of any piping, ductwork, or conduit occurs.
