# Environmental science and engineering A-E services, sources sought
The exact SAM notice N3943027R5001 concerns environmental science and engineering architect-engineer services planned for an indefinite-delivery, indefinite-quantity schedule. Although SAM classifies it as a combined synopsis/solicitation, the original notice text identifies itself as an updated sources-sought notice seeking SF 330 submittals, states that there is no RFP package, and says the information needed for an SF 330 is in the notice. The text returned by the API truncates after “FAR PART 12 (COM”. SAM gives a response deadline of 2 November 2026 at 14:30 America/Los_Angeles. No award or value is reported.
