Which document typically initiates the start of construction work?

The document that typically initiates the start of construction work is the notice to proceed. This notice serves as an official communication from the owner or client to the contractor, indicating that all pre-construction requirements have been met, and the contractor is authorized to commence work on the project.

The notice to proceed is crucial because it signifies that the contract has been finalized, financing is secured, and any necessary permits have been obtained. This helps to establish a clear timeline for when the work should begin, ensuring that all parties involved understand their responsibilities and the projected start date.

While the construction contract lays down the terms and conditions of the project and the project scope statement defines the work to be completed, it is the notice to proceed that formally activates the agreement and marks the transition from planning to actual construction. The site evaluation report, on the other hand, provides important information about the site conditions but does not authorize the start of construction.
