#### 7.1.3.5 IfcSubContractResourceType

| Type de ressource de sous-traitance
| Unterauftragnehmer - Ressource -Typ

The resource type IfcSubContractResourceType defines commonly shared information for occurrences of subcontract resources. The set of shared information may include:

- common productivities
- common cost rates
- common properties within shared property sets

It is used to define a subcontract 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 IfcSubContractResourceType are represented by instances of IfcSubContractResource.
