How The KO Deals With Proposal Assumptions

In this episode of the Contract Warrior Podcast, Christopher Williams — former NAVFAC Contracting Officer with 17 years of experience — explains how proposal assumptions are handled during the pre-award phase of federal contracting. Many contractors hesitate to include assumptions in their proposals, or misunderstand how they are evaluated by the Government. This episode breaks down when assumptions are appropriate, how they can influence the contract if not addressed before award, and why they must be reasonable, logical, and defensible. It also covers how assumptions can be used in both pre-award proposals and post-award change order negotiations. If you are submitting proposals for federal construction, A&E, or service contracts, this is a critical concept that can directly impact both award outcomes and contract execution.
