The Navy is seeking industry input via a Request for Information/Sources Sought Notice to identify potential sources capable of upgrading the Personnel Accountability System (PAS) in support of the Navy CAC Program Management Office. This is market research only, not a solicitation, and responses are voluntary with no reimbursement of costs. A draft Performance Work Statement accompanies the RFI, and interested firms must submit a capability statement limited to two pages, including company information, business size/NAICS, and contract vehicle availability. The expected NAICS code is 541512 with a $34 million small business standard, and the requirement is anticipated to be solicited as other than small business unless a small business set-aside is justified. Responses should be submitted via email to the specified Navy contact; no facsimile responses will be accepted.
