Technology streamlines construction process
An electronic database alternative to traditional construction documents, Building Information Modeling (BIM) applies multi-dimensional modeling computer software updated in real time.
BIM outperforms two-dimensional CAD drawings by adding more dimensions and geometry, materials information and ongoing updates to the buildingscape. However, BIM does present potential new legal and risk management considerations, including issues of control, professional responsibility, standard of care, insurance and allocation of risk/liability.
Cost savings attributed to BIM are variously estimated at 4 percent to 8 percent of project cost, with most savings attributed to spotting design problems and interferences at early stages and enhanced project coordination. Other cited cost-control advantages of BIM include the following:
Materials inserted into the design can be evaluated and estimated for the entire job; Expenses and budget can be quickly updated and calculated as work progresses; Project progress can be quickly updated, along with schedules and deliveries and Proposed changes can be inserted into the model and results and cost evaluated.
BIM is defined by the American Institute of Architects as a digital representation of the physical and functional characteristics of the Project. Building Information Modeling means the process and technology used to create the model. (AIA, Document E202 Building Information Modeling Protocol Exhibit, Art. 1 § 1.2.1 (2008).
BIM is an improvement upon traditional CAD drawings by including 3-D geometry and actual building parts and systems. BIM includes information on materials, specifications, quantities, cost and geometry. BIM breaks down barriers on a project in favor of a collaborative process where design professionals, engineers, contractors, subcontractors and specialty manufacturers work from one BIM model.
