Contractor Guidance for Your Bid

Government can change fixed-price contracts unilaterally. You're entitled to compensation for reasonable cost and schedule impacts. The key is documenting impact immediately when changes occur—don't wait until project end to submit claims. Track all change-related costs separately. Without contemporaneous documentation, you'll have trouble proving impact.
