BIM is a process that continues to evolve with the addition of contemporary tools available to construction managers. CAD programs automated many of the tasks that used by be done by hand and drawing board as well as integrated the complexities architect and engineering drawings. Two dimensional renderings of design are output of such CAD programs. 3D scanning can bring infinite detail to an object and be incorporated into the BIM model. Finally, project management software creates a timeline for underlying tasks and job completion.
As of 2007, Government funded construction projects must utilize Building Information Modeling. As a result, new technologies and tools must be embraced by owners, architects, engineers, general contractors, and all the various sub‐contractors. It should be no surprise that there may be challenges to this implementation. Already BIM is being used as a resource in litigation. Its design, operation, and history of implementation is critical to litigators.
