Only holders of the Navy's SeaPort-NxG multiple-award contract (MAC) can bid on this Naval Surface Warfare Center Carderock solicitation for scientific and technical services on how underwater and air explosions (UNDEX and AIREX) affect Navy ships. Offers go through the PIEE Solicitation Module (the Navy's online portal for SeaPort-NxG) and are due November 24, 2026, 10:00 AM Eastern. Proposals from non-MAC holders will not be evaluated.
Who can bid
- Limited competition: only holders of the Navy's SeaPort-NxG multiple-award contract can bid, not every business that meets the set-aside.
- Hold a SeaPort-NxG multiple-award contract (MAC); proposals from non-MAC holders will not be evaluated
- A PIEE account to receive solicitations and submit proposals
How to submit: PIEE Solicitation Module; SeaPort-NxG holders need PIEE accounts to receive the solicitation and submit proposals. What to include is under Full summary below. Check the solicitation's instructions on SAM.gov.
Things to watch
- Serious: Only SeaPort-NxG MAC holders can bid. A business that does not already hold this contract cannot bid, and non-holders' proposals are not evaluated.
- Worth checking: PIEE account needed to receive the solicitation. The Navy moved from the old SeaPort portal to the PIEE Solicitation Module, so setting up an account takes time and is needed to bid.
- Minor: Questions go through PIEE, not email. Amendment 0001 fixes the question process: use the PIEE question function, not the email in provision L-215-H006(c).
