Contract Change Orders in Construction: Protecting Margins from Unpaid Scope Creep

The Hidden Danger of Handshake Scope Changes

Every contractor has experienced it: an owner or property manager asks for "just one quick modification" during walkthrough. Two weeks later, thousands of dollars in labor, crane rental, and specialized fittings have been invested, but when the final bill arrives, the client disputes the charge because no written agreement exists.

AIA-Standard Financial Reconciliation

A legitimate contract amendment must clearly document four financial data points:

1. Original contract value prior to amendment
2. Net change in contract sum from previous approved change orders
3. Exact addition or deduction for the current scope change
4. Revised total contract sum and revised substantial completion date

By capturing dual contractor and client signatures on-site before mobilizing materials, you eliminate 99% of billing disputes.
