What Is a Contracting Officer (CO / KO)?
A Contracting Officer (CO), sometimes referred to as a KO, is the government official authorized to enter into, administer, modify, and terminate contracts on behalf of the federal government.
Only a warranted Contracting Officer has the legal authority to bind the government in a contractual agreement.
Key Characteristics of a Contracting Officer
The CO is the only individual who can legally bind the government, modify contractual terms, approve equitable adjustments, and issue final decisions in disputes.
Technical representatives, program managers, and CORs may provide direction, but only the CO can authorize changes that impact contract scope, cost, or schedule.
Warranted Authority
A Contracting Officer receives authority through a formal warrant specifying dollar thresholds, types of contracts permitted, and scope of authority. A CO cannot exceed the limits of their warrant.
Entering Into Contracts
The CO issues solicitations, evaluates proposals, conducts negotiations, and awards contracts.
Administering Contracts
During performance, the CO approves modifications, resolves contractual issues, interprets contract terms, and ensures compliance with regulations.
Terminating Contracts
The CO may terminate contracts for convenience, for default, or for cause in commercial item contracts.
Regulatory Framework
Contracting Officers operate under:
Federal Acquisition Regulation (FAR), particularly FAR Part 1.602 which outlines CO authority and responsibilities
Defense Federal Acquisition Regulation Supplement (DFARS), when applicable
Contract Disputes Act
Why the Contracting Officer Matters for Contractors
For contractors, understanding the CO's exclusive authority is critical. If a contractor is performing under a federal contract and the program office requests additional work:
The contractor cannot begin new work based solely on program office direction
The CO must issue a formal modification
Only the CO can legally expand scope or adjust funding
Failure to follow this rule can result in nonpayment or unauthorized commitments.
Understanding the distinction between the CO and other roles prevents scope creep and payment disputes. A Contract Specialist supports the CO but cannot bind the government. A Contracting Officer's Representative (COR) oversees technical performance but cannot change contract terms. A Program Manager defines requirements but does not hold contractual authority.
Common Misconceptions About the Contracting Officer
Anyone in the contracting office can modify the contract.
Only a warranted CO can legally modify a contract.
The CO must approve every operational detail.
The COR manages day-to-day oversight, but major contractual actions require CO approval.
CO authority is unlimited.
Authority is limited by the warrant and regulatory framework.
