Building Information Modeling (BIM) is no longer just for architects, design engineers and general contractors. New advances in BIM technology allow concrete contractors to build constructable models that can streamline internal processes to improve efficiency and productivity throughout the project lifecycle.

While constructable models are BIM, not all Building Information Models are constructable. The difference between design models and constructable models center on the level of accuracy, development and detail present in the model.

To be useful to a concrete contractor, a 3D project model must be constructable. That means it includes accurate, actionable geometry and data that concrete contractors can use to estimate, plan and manage pours. It will include accurate geometry and accurately sized and located embedded items to ensure conflicts are immediately obvious. It also might include pour breaks, rebar, and formwork and shoring detail, as well as associated data such as grade and mix designs.
