More and more General Contractors and Construction firms find that they can significantly reduce construction delays and cost overruns by doing a "virtual build" before beginning physical construction. This allows a contractor to evaluate the project for constructability. U.S. CAD works with these types of firms to take their 2D construction documents from the various design disciplines and turn them into 3D BIM models. We can then help to bring these models together for electronic clash detection and conflict resolution. This allows RFIs and change orders to be issued prior to physical construction, before they become issues in the field and delay the project.

Utilizing phasing, we can develop the BIM models in conjunction with the project timelines to increase communication and gain a better understanding of the construction process for project stakeholders. Construction sequences can be simulated for quick and effective decision making by the contractor, design team, and project owner. Schedule sequences can be stepped through to show the project at particular moments in time, and linked to the actual project construction schedule.

In addition, the information from a Building Information Model can be used to perform quantity take-offs for tighter budgeting and cost estimation.

We can provide BIM deliverables in a variety of different file formats for use by the extended design team such as Revit, Civil 3D, NavisWorks, even 2D or 3D AutoCAD DWG files.
