Pset: Pset_PreSupportCommon

Applicability: IfcBuiltSystem/TUNNEL_PRESUPPORT, IfcTunnelTypicalSection/EXCAVATIONSUPPORT, IfcElementAssembly/PRESUPPORTVAULT, IfcElementAssembly/PRESUPPORTFACE

Description:

Properties describing the characteristcs of excavation pre-support measures.

Property	Datatype	Description
PreSupportLocation	PEnum_PreSupportLocation	Specifies whether the pre-support is in face or around circumference.
UserDefinedPreSupportLocation	IfcLabel	Specifies a user defined pre-support location. Used when PreSupportLocation is set to USERDEFINED.
PreSupportType	PEnum_PreSupportType	Specifies the type of pre-support applied.
UserDefinedPreSupportType	IfcLabel	Specifies a user defined type of pre-support applied. Used when PreSupporttype is set to USERDEFINED.
Arrangement	PEnum_PreSupportArrangement	Specifies whether the pre-support is simple or staggered.
BoreholeLengthPlanned	IfcPositiveLengthMeasure	Existing property.
BoreholeOverlap	IfcLengthMeasure	Overlap of staggered boreholes.
UsefuleLength	IfcLengthMeasure	Length that can be used, generally length less overlap.
DrillingDiameter	IfcPositiveLengthMeasure	Property to be removed when Pset_BoreholeConstruction is merged and DrillingDiameter from there is reused.
IsBoreholeCased	IfcBoolean	Specifies whether the boreholes are cased or not.
DrillingMethod	PEnum_DrillingMethod or IfcLabel?	There is a DrillingMethod from Pset_SpatialGeoObsBorehole as IfcLabel - reuse (and generalize description)?
AreHolesGrouted	IfcBoolean	Specifies whether holes are grouted after insertion of pipes/bars.

Added generic PEnum constant descriptions and reused generic DrillingMethod from geo instead of the PEnum.
