IFC (IFC4X3_ADD2) under development Pset_DuctSegmentTypeCommon Semantic definition

Duct segment type common attributes. Applicable entities Properties

Name Property Type Data Type Description
Reference IfcPropertySingleValue IfcIdentifier

Reference ID for this specified type in this project (e.g. type 'A-1'), Also referred to as "construction type". It should be provided as an alternative to the name of the "object type", if the software does not support object types and no classification reference to a recognized classification system used.

Status IfcPropertyEnumeratedValue PEnum_ElementStatus

Status of the element, predominately used in renovation or retrofitting projects. The status can be assigned to as "New" - element designed as new addition, "Existing" - element exists and remains, "Demolish" - element existed but is to be demolished, "Temporary" - element will exists only temporary (like a temporary support structure).

CrossSectionShape IfcPropertyEnumeratedValue PEnum_DuctSegmentShape

Cross sectional shape. Note that this shape is uniform throughout the length of the segment. For nonuniform shapes, a transition fitting should be used instead.

WorkingPressure IfcPropertySingleValue IfcPressureMeasure

Working pressure.

Pressure classification as defined by the authority having jurisdiction (e.g., SMACNA, etc.).

PressureRange IfcPropertyBoundedValue IfcPressureMeasure

Allowable maximum and minimum working pressure (relative to ambient pressure).

TemperatureRange IfcPropertyBoundedValue IfcThermodynamicTemperatureMeasure

Allowable maximum and minimum temperature.

LongitudinalSeam IfcPropertySingleValue IfcText

The type of seam to be used along the longitudinal axis of the duct segment.

NominalDiameterOrWidth IfcPropertySingleValue IfcPositiveLengthMeasure

The nominal diameter or width of the duct segment.

NominalHeight IfcPropertySingleValue IfcPositiveLengthMeasure

The nominal height of the object. The size information is provided in addition to the shape representation and the geometric parameters used within. In cases of inconsistency between the geometric parameters and the size properties, provided in the attached property set, the geometric parameters take precedence.

Reinforcement IfcPropertySingleValue IfcLabel

The type of reinforcement, if any, used for the duct segment.

ReinforcementSpacing IfcPropertySingleValue IfcPositiveLengthMeasure

The spacing between reinforcing elements.
