In the post-award phase, contract modifications, such as change orders, are common activities.

• A. Review of completed portions
• B. Development of bid specifications
• C. Change orders
• D. Issuance of solicitation document

Answer: (C)

In the post-award phase, the project team must manage how the original contract unfolds as real conditions on the ground change. When scope, design, timing, or unforeseen issues require adjustments, the formal mechanism to handle these is a contract modification known as a change order. It explicitly documents what is changing, how much it will cost, how the schedule shifts, and who approves the change, ensuring the agreement stays accurate and enforceable as work progresses. This keeps the project aligned with evolving needs and provides a record of impacts for both parties.

Reviewing completed portions is part of monitoring and closeout activities, not a tool for modifying the contract after award. Development of bid specifications and issuance of solicitation documents occur before award to define requirements and select a contractor, not during the post-award modification process.
