What document indicates that construction work has been officially completed?

The document that indicates that construction work has been officially completed is the Notice of Completion. This formal notification is typically filed by the contractor with the local governing authority or the client, and it serves as an official acknowledgment that the work has reached the final stage.

The Notice of Completion is important for several reasons: it starts the timeframe for the warranty period, it allows the owner to begin the process of final approvals and occupancy, and it can also affect the timing of lien rights for subcontractors and suppliers. By filing this notice, it assures all parties involved that the project has reached a significant milestone and provides a clear indication that construction activities have been concluded.

Other documents, while related to the process of completion, do not serve as the official indication of construction completion. For instance, a Completion Certificate may validate that work adheres to the agreed standards but is often different from the formal notification provided by the Notice of Completion.
