Sources Sought FA8903-OT-MACH1 (MACH-1 Modernized Agile Construction Horizons) is an Air Force umbrella notice: no offers are requested here, and each project is posted later as its own Area of Interest (AOI) with a three-phase process. The 772nd Enterprise Sourcing Squadron (772 ESS) plans to award Other Transaction Agreements (OTAs), flexible agreements that are not regular government contracts, for construction and repair work. SAM.gov lists JBSA Lackland, TX, and gives no response due date.
Who can bid
- Registered in the System for Award Management (SAM) and in the government electronic invoicing system named in the agreement (for example WAWF or iRAPT), to receive an award
- Good standing, including not being on the federal excluded parties list
- Experience on similar construction or alteration projects (past performance and credentials)
Things to watch (7)
From the version posted Oct 22, 2026.
- Serious: Three-phase process; later phases are by invitation. Each AOI starts with a Phase 1 written brief. Only firms whose briefs have merit may be invited to the Phase 2 oral pitch, and Phase 3 may follow, so a firm that skips Phase 1 may be shut out. This notice sets no due date for any phase; each AOI will.
- Serious: Not a regular government contract. Awards are Other Transaction Agreements, so FAR and DFARS rules do not apply. Terms, pricing type, wages and protections are negotiated or set per project, so read each AOI carefully.
- Worth checking: Wage rules set per project. The notice does not say whether the Davis-Bacon Act (federal prevailing wage law for construction) applies. Each AOI states its own labor standards.

- Worth checking: Follow-on work without further competition. A firm that delivers a usable facility may get follow-on work with no new competition, which could favor the first winner and shut out others.
- Minor: Briefs may be reused without re-advertising. Phase 1 briefs may sit in a Solutions Repository for 12 months and be shared with other Air Force units; you can opt out on the cover page.
- Minor: Government can cancel projects. Time spent on a brief or pitch may be lost because the Government can cancel an AOI before award, and requests depend on funding.
- Minor: Bonding and finances may be judged. Some AOIs may evaluate financial health and the ability to provide payment and performance bonds.

- Estimated value

- How they'll choose

- Phase 2 Pitch: (a) technical and logistical depth, (b) schedule approach and acceleration, (c) responsiveness to the AOI's criteria
- Phase 3 Full Proposal (if used): criteria, deliverables and weights set in an Evaluation Amplification Letter (EAL) sent to selected firms
- Menu of possible AOI criteria includes constructability, schedule risk, site logistics, financial risk and bonding, safety, environmental, quality, warranties, cybersecurity and intellectual property

- Phase 1 Solution Brief covers: title page with company name, title, date, point of contact, email, phone, SAM unique entity ID (UEI), address and the AOI addressed
- Phase 1 also includes a one-page executive summary, a core concept (method, estimated schedule, disruption plan and a rough order of magnitude price) and credentials on similar construction or alteration projects

- All white papers, pitches and proposals must be unclassified
- Any requested price breakdown must be an Excel file without locked cells

The MACH1 (Modernized Agile Construction Horizons) framework is utilized by the 772nd Enterprise Sourcing Squadron (772 ESS) to explore and/or execute innovative, agile, or modernized construction and delivery capabilities. MACH1 is designed to bypass the administrative lag of traditional procurement and leverage industry expertise, leading capabilities, and highly flexible project delivery models. The 772 ESS executes this program under the standalone statutory authority of 10 U.S.C. § 2808a(a), which authorizes the Secretary concerned to enter into transactions (other than contracts, cooperative agreements, or grants) to carry out repair and construction projects for facilities, including the planning, design, engineering, prototyping, piloting, and execution of such repair and construction projects. Facility Construction or Repair Project opportunities will be independently posted as an Area of Interest (AOI) -- "MACH1_AOI_Project Title" -- referencing this MACH1 parent notice that outlines a competitive, streamlined three-phase procedure to submit responses to active AOIs. For further details: See attachment PDF, "772 ESS.PKA.MACH1_Umbrella Program Notice_AMEND 2_22 Oct 26" Posting Updates a/o 24 Aug 26: Original MACH1 Posting Type changed from "Special Notice" to "Sources Sought" & Original PDF, "772/PKA MACH-1 Umbrella Program Notice 03AUG26' was replaced by Amendment 1 named above.
