The use of BIM goes beyond the planning and design phase of the project. It is also important during the construction phase and for post-construction phases and facility management.

Model management

A Building Information Model spans the whole concept-to-occupation time-span. To ensure efficient management of information processes throughout this span, a BIM Manager (also sometimes defined as a virtual design-to-construction, VDC, project manager - VDCPM) might be appointed. The BIM manager is retained by a design build team on the client's behalf from the pre-design phase onwards to develop and to track the object-oriented BIM against predicted and measured performance objectives, supporting multi-disciplinary building information models that drive analysis, schedules, take-off and logistics.

BIM in construction management

Participants in the building process are constantly challenged to deliver successful projects despite tight budgets, limited manpower, accelerated schedules, and limited or conflicting information. The BIM concept envisages virtual construction of a facility prior to its actual physical construction, in order to reduce uncertainty, improve safety, work out problems, and simulate and analyse potential impacts. Sub-contractors from every trade can input critical information into the model before beginning construction, with opportunities to pre-fabricate or pre-assemble some systems off-site. Waste can be minimised on-site and products and resources delivered on a just-in-time basis rather than being stockpiled on-site.

BIM in facility operation

BIM can bridge the information loss associated with handing a project from design team, to construction team and to building owner/operator, by allowing each group to add to and reference back to all information they acquire during their period of contribution to the BIM model. There are many benefits to the facility owner or operator who adopt BIM. For example, a building owner may find evidence of a leak in his building. Rather than exploring the physical building, he may turn to the model and see that a water valve is located in the suspect location. He could also have in the model the specific valve size, manufacturer, part number, and any other relevant information.
