Building Information Modeling

What is BIM? Building information modeling (BIM) is a process involving the generation and management of digital representations of physical and functional characteristics of a facility.

The process produces the building information model; which encompasses building geometry, spatial relationships, geographic information, quantities, and properties of building components, equipment, etc. • • • • • • • Reduces design related errors Facilitates early MEP design coordination Makes design changes quicker and more accurate (Better decisions earlier in process) Improves efficiency Reduction in drafting hours Maximize Design accuracy Easily detects conflicts with other trades Once the building is constructed and commissioned, the data can be used by the owner in support ongoing facilities asset management related activities.

BIM & Precast Concrete

Unique Use & Development

Precast Projects are modeled 3D in Autodesk Revit Structure® including required connections.

• 3D Models are typically shared between the design team, contractor and other subcontractors & checked for clashes • 2D erection drawings & connection details are created directly from the model • Building Information is exported from the 3D model and used directly to produce Each precast “piece ticket” production drawing.
