Final answer:
The contractor submits a subcontractor list to the architect and owner, providing details on the qualifications and experience of the subcontractors to ensure transparency and gain approval.
Step-by-step explanation:
The contractor usually notifies the architect and owner of the subcontractors who will be working on a project through a formal process known as the submittal of a subcontractor list. This typically involves the contractor submitting a document to the architect and owner that enumerates all the subcontractors that will be used for the project. The document often includes information on the subcontractors' qualifications, prior experience, and other relevant details. This process is crucial for ensuring that the architect and owner approve the subcontractors and that there's transparency and agreement on who will be conducting work on the construction project.
