Dealing with Unauthorized Change Orders: PM Directions vs. Contracting Officer Authority

The field environment on a commercial or federal project moves fast. Deadlines are tight, material delivery windows are narrow, and unexpected structural conflicts occur daily. When a crisis hits the field, a General Contractor's Project Manager or a government agency’s technical representative will walk up to your foreman and give a direct order: "We need to alter this routing pattern immediately. Do it now to keep the schedule on track, and we will catch up on the paperwork during the next billing cycle."

Your crew acts in good faith. You reroute materials, authorize overtime, and deploy equipment to handle the emergency.

But weeks later, your formal change order request gets completely rejected. The project owner states that the field modification was completely unauthorized, and they owe you exactly $0. You have just fallen victim to the **Unauthorized Change Order Trap**.

The Law of Implied vs. Actual Authority

The brutal reality of public and heavy commercial contracting is that the law does not care about good intentions or verbal handshakes. It cares strictly about **Actual Authority**.

Under federal acquisition regulations (specifically FAR Part 1.6), a government Project Manager, Contracting Officer’s Representative (COR), or technical inspector possesses absolutely **no legal authority to alter a contract or obligate funds**. They have *implied authority* to supervise field production, but they cannot sign checks.

Only an officially designated **Contracting Officer (CO)** possesses the legal power to bind the government financially. If you execute extra work based entirely on a PM’s verbal nod, the law views your labor as a voluntary contribution. The government is under no legal obligation to pay for it, and the prime contractor will use that same logic to deny your back-charges.

The "Constructive Change" Catch-22

General contractors capitalize on this framework by inserting aggressive boilerplate text into subcontracts that forces you to choose between two catastrophic options:

1. If you refuse to perform the extra work until a formal, written modification is signed by the CO, the GC will threaten to declare you in default for **disrupting the project schedule**.
2. If you perform the work to keep the peace, you assume the entire financial risk of the modification being rejected during the final closeout audit.

To survive this system, you must understand how to safely convert an unauthorized verbal order into a legally recognized **Constructive Change** before your crews deploy their tools.

Establishing an Unshakeable Field Routine

Never risk your company's weekly payroll on a verbal field instruction. Take control of your change management track with these non-negotiable operational steps:

• Issue an Immediate Written Directive Notice: The exact millisecond a verbal change is requested, send a formal email notice back to the GC before executing any labor: *"Pursuant to your field direction on June 2, we are proceeding with the re-routing modification under protest. We estimate the impact to be $12,500 and 3 working days, and expect a formal written modification from the Contracting Officer within 48 hours."*
• Segregate All Tracking Codes: Instruct your field foreman to track every single hour of labor and every line item of material used for that specific modification on a separate, dedicated timecard stamped "Disputed Field Directive." Never blend change-order labor with your base scope logs.
• Strike Out "Work First, Settle Later" Boilerplate: Modify incoming contracts to ensure you have the right to halt production on disputed changes if the cumulative cost of unauthorized modifications exceeds 5% of your total contract value.
