BIM and Construction Management: Proven Tools, Methods, and Workflows

2.5. Estimating

Extracting quantities, areas, and volumes from a model is one of the most useful functions BIM technology offers. The following tutorial uses a Revit model and shows how to use Innovaya's estimating tool to extract quantities from the model and then tie them to a Timberline estimate. Other software combinations are also available, such as Vico Software and Beck Technology's DProfiler, with which you can accomplish similar tasks.

Estimating takes place during preconstruction (see Figure 2.9). The procedure that follows shows how to complete updates. This example assumes that all you have received is a business development model that is in its infancy. You start by gathering square footage data and then begin to link model objects ...
