Draft AOI: Industry Questions and Comments The Government welcomes industry questions and comments regarding this Draft Area of Interest (AOI). For purposes of this market engagement, questions and comments will be treated differently, as described below. Questions: Questions are requests for clarification, interpretation, or additional information regarding the Draft AOI and are intended to solicit a written response from the Government. The Government intends to respond to questions received by 4:00 PM Central Daylight Time (CDT) on 26 October 2026 , with a target of publishing responses by close of business on 28 October 2026 . Questions and Government responses will be made available to all prospective respondents. Comments: Comments are industry observations, recommendations, suggested revisions, or other feedback offered for Government consideration that do not request a response. The Government will take comments received by 4 :00 PM CDT on 26 October 2026 under advisement in developing the Final AOI. The Government will not individually respond to or publish industry comments. Submissions After the Deadline: The Government will review and contemplate all questions and comments received after 5:00 PM CDT on 26 October 2026. However, due to the acquisition schedule, the Government cannot guarantee that late submissions will influence development of the Final AOI. The Government may elect to respond to questions received after the deadline following publication of the Final AOI. Industry participants are encouraged to clearly identify each submission as either a Question or Comment . Submissions containing both should distinguish the questions requiring Government responses from comments provided solely for consideration. The Government appreciates industry's participation and welcomes constructive feedback to support development of a clear, competitive, and commercially viable Final AOI. The following represents the anticipated Final AOI SAM.gov description: MACH1 Area of Interest: F-47 Campus at Nellis AFB, Rapid Delivery Progressive Design-Build The 772d Enterprise Sourcing Squadron (772 ESS), in coordination with the Air Force Civil Engineer Center (AFCEC), is seeking highly qualified Design-Build teams to deliver the Rapid Delivery Projects supporting the F-47 mission at Nellis Air Force Base, Nevada, utilizing a Progressive Design-Build (PDB) model. This Area of Interest (AOI) is issued under the Modernized Agile Construction Horizons (MACH1) Umbrella Program Notice, FA8903-OT-MACH1. Any resulting agreement will be an Other Transaction Agreement (OTA) executed under the authority of 10 U.S.C. § 2808a . Respondents shall comply with the MACH1 Umbrella Program Notice and the project-specific requirements established in the attached AOI. Program Overview The F-47 Campus at Nellis AFB is an approximately $1.057 billion total programmed military construction initiative intended to provide the facilities and infrastructure necessary to support the F-47 mission. This amount includes construction, contingency, design, construction security, and other applicable project costs and does not represent the construction agreement value available under this AOI. The present acquisition contemplates award for the Rapid Delivery Projects under Milestones 2 through 4 only, consisting of: Combined Operations and Maintenance Hangar. Reprogramming Laboratory. Simulator Facility. Aircraft Apron with Sunshades. Supporting utilities and infrastructure necessary for permanent operation of the Rapid Delivery facilities. The Government strongly prefers to select one Design-Build team capable of delivering all Rapid Delivery Projects, while reserving the right to select up to four teams if warranted by program requirements and permitted by the applicable acquisition authority. The Government also values organizations possessing the qualifications and resources to support the remaining Nellis F-47 Campus. However, selection under this AOI does not guarantee Milestone 5 or subsequent Agreement(s). Progressive Design-Build Delivery Approach The Government intends to initiate design and preconstruction services following completion of the Planning Charrette Reports establishing the initial mission requirements. The selected Design-Build team will work collaboratively with AFCEC and its Owner's Advisor to advance facility designs, evaluate alternative technical and construction solutions, develop cost and schedule strategies, and establish commercially supportable construction pricing. The Government contemplates negotiating firm-fixed-price construction agreement at approximately 65% design completion, subject to sufficient scope maturity, risk allocation, and commercial cost viability. Advanced design packages, early construction activities, and long-lead procurement may be considered where appropriately justified and authorized. AFCEC seeks a collaborative construction partner committed to delivering the greatest possible mission capability and value for the resources invested. The Government intends to consider innovative design and construction approaches, including industrialized construction methods, commercially effective Agreement commitment strategies, and practical alternatives that improve affordability and schedule performance. Three-Phase Selection Process The Government intends to conduct an expedited three-phase selection process under MACH1: Phase 1: Solution Brief. Respondents will submit qualifications and technical information demonstrating the capabilities of their actual proposed design and construction organizations. The attached AOI establishes ten project-specific technical factors and a maximum of 20 narrative pages, with separately permitted appendices. No construction price or rough-order-of-magnitude construction estimate is required during Phase 1 Submissions. Phase 2: Oral Presentations / Pitch Sessions. Selected respondents will be invited to participate in oral presentations. Detailed instructions and additional technical information will be provided to invited respondents, subject to applicable information-security requirements. Phase 3: Full Phase 3 Submission and Negotiations. The Government intends to conduct direct negotiations with selected respondent(s), subject to applicable authority and Agreements Officer approval. Commercial viability of the price will be evaluated before award. Anticipated Acquisition Schedule AOI Release: October 30, 2026. Initial Industry Questions Due: November 4, 2026.
