Quantity Update / Forecast
The forecast should reflect 100% of the project scope and start off as estimate through to As-built quantities. Normally the information is extracted from Contractor’s engineering / weight data systems and imported and reviewed / adjusted by Company. Figure 2 explains the relation between estimate, IFC Quantities and finally As-Built quantities.

Measured – IFC / As-Built Quantities

Contractor Estimate – Quantities that neither is IFC / As-Built nor modeled.
