Agreement on an add-on view to the coordination view to include base quantities 

Based on          IFC2x3

Initiator            ISG Meeting-Helsinki

Effects              Extended Coordination View

Date                   2007 05 23


The export of base quantities is an add-on functionality that can be provided on top of the extended coordination view. The exact definition of base quantities is included in the model view definition for QTO.

An additional validation / certification for supporting base quantities may be organized, it will not be validated as part of the existing extended coordination view.

Currently the base quantities are an export-only requirement for an add-on to the extended coordination view. Other BIM/CAD applications are not required to import base quantities, they should be ignored on import to avoid potentially inconsistent and redundant property data.
