BIM. Building Information Modeling replaces standard two-dimensional construction drawings with multi-dimensional computer models.

The technology helps our project team identify and resolve issues during design, rather than during construction, avoiding additional expense and schedule delays. Sundt's use of BIM was fully integrated during the design and construction of our new corporate headquarters. It launched our SIMCON (simulated construction) department, which today is one of the largest of its kind for a general contractor. SIMCON modelers take the electronic files of various building systems, usually provided by the designer and key subcontractors, and integrate them into a collaborated 3-D model. The software is then used to run a "collision report," which shows each instance where one element intersects, or "collides" with another. All parties on the project team work together to analyze and resolve these collisions on a weekly basis. As the design progresses, models are revised and collision reports are updated and analyzed. When the design is complete, virtually all of the problems that used to surface during construction have been identified and resolved. Plus, it allows our owners to have a clear visualization of what the finished product will look like and take a virtual "tour" of the project.

The Project Schedule can be integrated into the 3D model, creating a 4D model. This is used to analyze the schedule for accuracy as well as a tool to help explain the sequence of work to different trades. The 4D model shows if work is out of sequence, if multiple trades are scheduled to work in the same area creating a low productivity environment, and can be used to analyze "what if" scenarios.

Sundt is now using modeling on all of its design-build projects, and many others as well. Most industry experts believe that in the not-too-distant future, all structures, including single-family homes, will be designed using BIM tools.
