Équipement utilisé pour la construction
Baugerät - Ressource

IfcConstructionEquipmentResource is usage of construction equipment to assist in the performance of construction. Construction Equipment resources are wholly or partially consumed or occupied in the performance of construction.

HISTORY  New entity in IFC2.0.

Occurrences of IfcConstructionEquipmentResource are products that are used as resources to assist the process of construction. More specifically, they are products that are standalone items brought to a project to fulfil a particular purpose. Examples might be a tower crane or other mobile crane, a screwing machine, or a lifting hoist.

Instances of any subtype of IfcProduct may be assigned to the equipment resource using IfcRelAssignsToResource in order to characterize the equipment further, as described at the supertype IfcResource. Examples of relevant subtypes of IfcProduct are IfcTransportElement, IfcDiscreteAccessory, or IfcProxy (for particular cases where more precise usage details are not available)
