Building Information Modeling (BIM)

Building information modeling (BIM) is the process of creating and managing a shared digital model of a facility that holds both its geometry and the information about its parts, used from design and construction through operation.

BIM starts as a coordinated 3D model and gains value as schedule, cost and operating data are attached to the same objects. For a garage, the payoff is fewer field clashes and a usable record for decades of maintenance. Illustrative.

Architects, engineers, contractors and owners work from the same model instead of separate drawing sets. The model is often extended beyond 3D geometry with schedule (4D), cost (5D) and facility management or sustainability data (6D), though the labels vary by firm.

Where it helps a parking project

After construction

  • An as-built model gives owners a record of what is where, from tendons to conduit.
  • Condition surveys and repairs can be tracked against the model over the structure’s life.

The Parkonomics view

The most valuable part of BIM for a parking owner may be the one that comes last: an accurate digital record of a structure that will be repaired for fifty years.
