7.3.3.2 IfcConstructionEquipmentResourceType

Équipement type utilisé pour la construction
Baugerät - Ressource -Typ

The resource type IfcConstructionEquipmentType defines commonly shared information for occurrences of construction equipment resources. The set of shared information may include:

It is used to define a construction equipment resource specification (the specific resource information that is common to all occurrences of that resource). Resource types may be exchanged without being already assigned to occurrences.

Occurrences of the IfcConstructionEquipmentResourceType are represented by instances of IfcConstructionEquipmentResource.

HISTORY  New entity in IFC4.

Assignment use definition

In addition to assignments specified at the base class IfcConstructionResourceType, a construction equipment resource type may have assignments of its own using IfcRelAssignsToResource where RelatingResource refers to the IfcConstructionEquipmentResourceType and RelatedObjects contains one or more IfcTypeProduct subtypes. Such relationship indicates the type of equipment to be used as input, which is instantiated as an occurrence assigned for each resource occurrence. There may be multiple chains of production where such product type may have its own task and resource types assigned indicating how to assemble such equipment.
