### Use Definition

A construction crew resource typically includes labor resource, equipment resource, material resource, subcontractor resource, as well as other crew resources. Construction crew resources are partially or wholly consumed, or occupied in a construction process (i.e. IfcTask). Since IfcCrewResource represents the resource types, individual persons are not required to be identified and linked to the crew resource, while they can be associated if needed.

The IfcCrewResource is enabled to contain other crew resource types (i.e. crew resource type nesting) through its relationship to IfcRelNests.
