4. Procedure

Phase 1: Identification and Notification

• Attach supporting documentation (e.g., site photos, RFI responses, or revised drawings).

Phase 2: Cost and Schedule Impact Analysis

5. Quality Assurance and Best Practices

• Pro-Tip: Always include a "no-cost" change order if the modification results in a zero-dollar impact to ensure the paper trail remains unbroken.

• QA Check: Ensure that the modification description specifically references the original contract section it supersedes.
