Pset_PrecastConcreteElementFabrication Production and manufacturing related properties common to different types of precast concrete elements. The Pset applies to manufactured pieces. It can be used by a number of subtypes of IfcBuildingElement.

The content depends on local standards. For instance in Finland it usually a one-letter acronym, e.g. P=Column, K=reinforced concrete beam,etc. Type Designator ProductionLotId The manufacturer's production lot identifier. Production Lot Id SerialNumber The manufacturer's serial number for the precast concrete element. Serial Number PieceMark Defines a unique piece for production purposes. All pieces with the same piece mark value are identical and interchangeable. The piece mark may be composed of sub-parts that have specific locally defined meaning (e.g. B-1A may denote a beam, of generic type ‘1’ and specific shape ‘A’). Piece Mark AsBuiltLocationNumber Defines a unique location within a structure, the ‘slot’ into which the piece was installed. Where pieces share the same piece mark, they can be interchanged. The value is only known after erection. As Built Location Number ActualProductionDate Production date (stripped from form). Actual Production Date ActualErectionDate Date erected. Actual Erection Date
