What should a COR do if an issue arises that cannot be resolved informally?

When an issue arises that cannot be resolved informally, the appropriate course of action for a Contracting Officer Representative (COR) is to contact the contracting officer for further action. This step is critical because the contracting officer has the authority and responsibility to manage contractual issues and ensure that the terms of the contract are upheld.

Involving the contracting officer not only brings additional expertise to the situation but also ensures that any action taken is in accordance with procurement regulations and policies. The contracting officer can take appropriate measures such as issuing a formal modification to the contract, facilitating communication with the contractor, or even initiating dispute resolution procedures if necessary. This step is essential for maintaining the integrity of the procurement process and resolving issues in a structured manner.

The other options either bypass the necessary protocols or risk further complicating the issue, which highlights the importance of following the correct chain of command and involving the contracting officer when informal resolutions fail.
