Who can bid
- Limited competition: only holders of a SeaPort-NxG multiple-award contract can bid, not every business that meets the set-aside.
- Hold a SeaPort-NxG multiple-award contract (MAC) in the unrestricted pool; no other offers will be considered
- A PIEE account, needed to receive solicitations and submit proposals
How to submit: PIEE Solicitation Module. What to include is under Full summary below. Check the solicitation's instructions on SAM.gov.
Things to watch
- Serious: SeaPort-NxG MAC holders only. Only holders of a SeaPort-NxG multiple-award contract can bid; offers from anyone else are not evaluated.
- Worth checking: PIEE account needed to get the solicitation. The Navy has moved from the legacy SeaPort portal to PIEE, and the solicitation itself is delivered there, not in this notice.
- Minor: Question instructions conflict. Provision L-215-H006(c) says to email questions, but the notice says all questions go through the PIEE Solicitation Module and that the solicitation will be amended.
