The construction phase normally begins with which type of letter?

• A. Notice to Proceed (NTP)
• B. Letter of Intent
• C. Change Order
• D. Purchase Order

Answer: (A)

The construction phase starts when the owner issues a Notice to Proceed, which formally authorizes the contractor to begin field work and mobilization under the contract. This document sets the official start date and triggers the project timeline, after all prerequisites like contract execution, bonds, insurance, and permits are in place. A Letter of Intent may indicate intent to contract but does not authorize starting construction. A Change Order adjusts scope or terms after work has begun, not at the project’s start. A Purchase Order handles procurement of materials or subcontracted services and does not by itself authorize the overall construction start.
