Authorized Signature

The answer is going to depend on your own agency regulations and culture.

For example:  option exercises.  I have been in an agency where the contracting officer signing the exercise had to have a warrant level appropriate for the potential value of the entire contract, and I am in an agency now where the contracting officer only needs a warrant level appropriate for the option being exercised.

Can other Level III contracting officers with less than $750M warrant have authority to sign documents related to the $750M project?

I have not seen authority stated or limited in terms of program value. FAR 1.602-1, "Authority," says that COs have authority with regard to binding the government by contract. Other than determinations and findings, FAR 1.602-1 does not mention authority with regard to internal documents. The wording used on the Certificate of Appointment, SF 1402, may provide a clue. Otherwise, it will be a matter of agency policy and tradition.

Thank you all for the responses.  Our culture is once a PCO is assigned, on the that PCO or someone with similar warrant signs related documents.  But with our new command policy that limited higher level warrants to only the highest in position, the task of signing Market Research, Inclusion of Options and release of Request For Proposal in SPS that do not require warrant level is getting challenged.

Your "culture"?  

Do you mean your policy, tradition, or practice?

Culture is our practice and tradition.  There is no written policy.
