Were the responses to the Sources Sought notice favorable? The Government intent was to determine the level of interest in the upcoming Hanscom Air Force Base Steam and Condensate Indefinite Delivery Indefinite Quantity Contract; Sources Sought and Questionnaire responses were not assessed for favorability.

Is an acquisition strategy for a competitive Solicitation under development? The Government intent is to conduct a competitive solicitation using FAR Part 14 Sealed Bidding procedures.

Is there an approximate time frame to watch SAM or a particular contract vehicle for information? The Government is in the process of finalizing the requirement documents and hopes to have a solicitation released soon.
