This contract is also for support of science, research and computing activities within the Terrestrial Information Systems Laboratory (TISL), also in the ESD. For the purposes of this document and contract the term HBG will be used to encompass all the Laboratories of the HBG sub-division and the TISL. NASA will conduct this acquisition as a small business set-aside. This competitive acquisition was originally contemplated as a Cost-Plus-Fixed-Fee (CPFF), Indefinite-Delivery/Indefinite-Quantity (IDIQ) contract with the ability to issue CPFF task orders. Following further acquisition planning and assessment of the Government's requirements, the contract structure has been modified. The HBG II Draft Request for Proposal (DRFP) posted on April 8, 2025 was issued as an IDIQ CPFF solicitation. As amended, this competitive acquisition will now result in a HYBRID Indefinite Delivery Indefinite Quantity (IDIQ) with the ability to issue Cost Plus Fixed Fee (CPFF) AND Firm- Fixed Price (FFP) task orders. The contract will have an effective ordering period of five years from the contract effective date. Interested offerors are encouraged to review the solicitation and all associated attachments for complete details regarding the requirements and proposal submission instructions. Please see the attached cover letter for additional information.
