What documentation is typically required from a contractor for payment releases?

The correct choice reflects the common practice in construction payment processes, where lien waivers, invoices, and proof of project completion are critical pieces of documentation.

Lien waivers serve as legal documents in which the contractor agrees to waive future lien rights against the property for the amount paid, providing security to the property owner that they will not face a lien claim for that portion of the work. Invoices are vital as they detail the charges for the services rendered and materials supplied, ensuring transparency in billing. Finally, proof of project completion, such as a certificate of completion or inspection reports, is essential to confirm that the work was satisfactorily completed before any payments are released. This documentation not only protects the interests of both parties but also assists in maintaining clear financial and legal records throughout the project's lifecycle.

The other options, while containing relevant documents, do not encompass the specific requirements for releasing payments effectively. Personal identification and tax forms relate more to the contractor's identity and tax obligations rather than project execution. Project proposals and contractor's licenses, though important for establishing capability and authority to work, do not serve the immediate purpose of facilitating payment. Insurance documents and work schedules are undoubtedly useful for risk management and planning, but they do not directly impact the payment release process
