Are there any restrictions on including contractor assumptions in FFP contracts?

There isn’t.  It’s negotiable.  In fact, assumptions often are included but subtlety overlooked.  Offerors make assumptions in proposals and contracting officers then incorporate technical proposals as part of the contract.  It’s a sloppy way of doing business but quite common.

Thanks formerfed, that is exactly what I thought. It has been hit or miss with this particular client so wanted to confirm.

@pconnerWhy do you want to include your assumptions in the contract? What legal effect do you think that would have?

Maybe we can categorize contractor FFP assumptions into two buckets for this discussion?

1. Proposal Pricing Assumptions.  Assumptions an offeror makes as part of developing its firm-fixed-price proposal.
2. Performance Assumptions.  Assumptions an offeror makes which condition or limit its offer, provide an excuse for non-performance, and so forth.

pconner, what kind of assumptions are you talking about?

Are there any known clauses or other provisions that prohibit these from being included?
