HISTORY New entity in IFC2.0.

An IfcSubContractResource can be used in cost estimating and work planning with or without specifying the subcontractor and contract agreement.
The purpose of an IfcSubContractResource is to indicate work of a particular type that is that is to be engaged through the use of a sub-contract. Its aim is to identify the description of the sub-contract work required. It can be used to identify the generic type of sub-contract resource that is required for a purpose without having to be specific about the actor (person or organization) providing the resource occurrence. It may be particularly useful when creating an overall plan for a process or processes. For instance, within maintenance or work planning there may be a known task that needs to be done which is planned to require an 'insulation specialist'.
A subcontract resource may be described at various stages and levels of detail through its assignments:
- Subcontract resource designated for particular tasks
- Actors identified to request bids
- Cost schedules (bids) received from actors
- Project order (work order, change order, etc.) executed
