Which document authorizes the contractor to begin work on a project?

The document that authorizes the contractor to begin work on a project is known as the Notice to Proceed. This formal notification is essential as it signals the official start of construction activities, aligning with the project timeline established in the contract. It ensures that all involved parties are aware that they may commence their respective tasks as outlined in the project documents.

The Notice to Proceed typically follows a series of pre-construction activities, such as contract negotiations and final approvals, confirming that all necessary prerequisites have been met before actual work begins. By issuing this notice, the project manager or owner provides clarity and sets a defined start date, which is crucial for project scheduling and management.

In contrast, other options serve different purposes: a Change Order modifies the original contract terms, a Request for Information (RFI) seeks clarification on project details, and a Punch List outlines tasks that need to be completed or corrected before project acceptance. None of these documents initiate the actual work phase of a project.
