The Department of Defense, specifically the Department of the Navy through NAVSUP FLT LOG CTR Norfolk, has issued a special notice regarding a modification to Contract N00189-21-D-Z043. The modification aims to increase the ceiling value of this sole source contract, which is an Indefinite Delivery, Indefinite Quantity Firm-Fixed-Price contract, allowing for additional orders to be placed before the contract's expiration on 31 August 2026. This contract is crucial for providing ongoing engineering and technical support services, and while the requirement remains unchanged, the follow-on contract has already been solicited and is set to be awarded prior to the contract's end date. Interested parties can direct inquiries to Danielle Udinson at danielle.udinson@navy.mil, with the notice closing on 9 January 2026 at 12:00 PM EST.
