Embracing BIM

Although not common yet, we are now beginning to see collaborative coordination efforts that use a single 3D model where the structure and architecture is shown in the same model. In complex geometric building shapes, working with intelligent 3D models is imperative. This is especially true in some of the non-traditional structures such as the Tempe of the Arts building.

Working with BIM software tools has opened up new methods of communication with contractors and subcontractors that were unheard of just a few years ago. Within Able Steel, our detailers have been using 3D detailing software for the preparation of steel erection and shop fabrication drawings for several years.

Thanks to an AISC initiative a few years ago, a digital standard for electronic communication, CIS/2, was established. Consequently, BIM software packages are continuing with unified standards and the steel detailing packages are now interoperable with the AEC BIM models.

The underlining factor driving the BIM movement has been the enhanced coordination tools among the design team (architect, structural and MEP engineers). In essence, the team generates a virtual prototype of the building containing all aspects - architectural, structural and mechanical which allows the team to coordinate and make better design decisions based on actual, accurate 3D geometries. Utilization of beam and column sizing that works structurally, and meets with the architect approval in terms of office space and ceiling heights on recent projects such as the ASU School for Nursing has proven successful. Furthermore, the model could be used as a construction tool by contractors and by owners (facilities management).

At Able Steel it is no longer a question of whether BIM will succeed or fail - it is already working its way onto projects and we have seen nothing but success. The challenge lies in trying to utilize all that structural BIM packages have to offer - coordination, documentation, scheduling, analysis and design. The key to success to us is early involvement to maximize the owner’s expectations and providing increased value to the overall project.
