Example CPFF Contract?

You probably won't find an actual contract unless you know someone who'll give you a copy of theirs.

The best you can do is search FedBizOps for cost-reimbursement RFPs. Of course, the qualify of what you'll find will be mixed and you cannot trust them as models. Some will contain specialized terms and custom texts that are not used in all cost-reimbursement contracts.

If you have access to FPDS-NG (or you are on good terms with someone who has access), you could always run an AdHoc query and limit your search to a relevant NAICS and CPFF contract type to get a list of contracts. If you're with DoD, you could look at the contracts via EDA. I imagine other agencies have similar sites for posting contracts. But, as Vern noted, this will just give you an idea of how the contracts were structured. It's not a guarantee that they are well-written.

That's why I was reluctant to pluck one out of FedBizOps. I hadn't thought of FPDS, but I'd have the same concern with those as well. Thanks!

Here are some "model" awards from the Office of Naval Research. I can't speak to the last time these were updated.

Thank you!
