Building Information Modeling

Building Information Modeling (BIM) is a process which provides for a 3-dimensional virtual information model. It is a ‘model’ oriented process as opposed to a 2-dimensional document process. The model and data contained therein can be used by all parties in the building process. The BIM model has application in the construction of new buildings as well the management and servicing of existing buildings.

BIM used in new building construction is sometimes referred to as virtual design and construction (VDC). It is employed to facilitate both design and construction in an integrated environment. Cost savings are realized with a more efficient design and documentation process. During design, the shared model provides for 3-dimensional visualization and enhanced coordination and input among all team members. Spatial and physical conflicts (‘clashes’) between building systems or components are revealed prior to construction and saves on unbudgeted change orders during construction. Alternate design schemes can be evaluated more quickly and in greater detail with associated costs. Real-time energy analysis can be performed to evaluate alternate design decisions, carbon footprints, and life cycle building costs.

During construction, cost savings are realized with more efficient cost estimating and accurate bids. The BIM model can be used in a 4-D virtual environment to generate more efficient scheduling. Cost saving are realized with shortened construction times and building Owners are able to occupy their structures sooner.

In existing structures, BIM technologies can be integrated with facilities management to improve space management and reduce operating costs, processes typically addressed by two-dimensional computer aided facility management (CAFM). Technical maintenance is aided with the BIM model providing quick and easy access to the building’s parts and inventory. It can be a data storehouse of relevant parts and suppliers. Models can display the elements and schedules requiring regular maintenance or replacement. Linked with cost databases, future operating costs can be projected. BIM for existing buildings provides a ready database of rooms, spaces, and square footages, allowing improved management of occupancy and space use. Security and emergency preparedness are enhanced by integrating accurate spatial schematics that can with surveillance systems, evacuation plans, and smart technologies. The virtual model can even be used for marketing as facets of the facility or operations can be viewed remotely.
