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.
