The effect of a modification is tied to when it is issued. For a solicitation amendment, change order, or administrative change, the effective date is the date the government issues the amendment. That issuance date is when the new terms are communicated and become binding, unless the modification itself specifies a different date. The other dates don’t determine when the change kicks in: award date relates to awarding the contract, signing date may occur later but doesn’t set the usual start of the amendment’s terms, and proposal submission date is about when bids were due, not when a modification becomes effective.
