Application ifcBuilding

For a tender, ifc is requested. We use ifc2x3. I have a question about the structure and application of the element ifcBuilding. In Revit there can only be one ifcBuilding under ifcSite. In Tekla it is possible to define ifcBuilding multiple times under one ifcSite. Is this allowed by the ifc2x3 standard?

Yes, you are allowed. This is a known limitation of Revit.
