PN 110205 - SOS Hangar Renovation - Progressive-Design-Build OT
DEPT OF DEFENSE.DEPT OF THE ARMY.US ARMY CORPS OF ENGINEERS.ENGINEER DIVISION SOUTH ATLANTIC.ENDIST WILMINGTON.W074 ENDIST WILMINGTON · Response deadline: Wed, 11 Nov 2026
What the government is buying
The U.S. Army Corps of Engineers, Wilmington District is soliciting proposals for renovation work to a Special Operations Support (SOS) hangar using a progressive design-build Other Transaction (OT) approach. A progressive design-build contract means the contractor is selected early based on qualifications and then collaborates with the government to develop the design before final pricing is established. An Other Transaction is a non-FAR agreement vehicle that allows for more flexible, commercially oriented procurement methods outside the standard federal acquisition regulations—typically used when traditional contracting approaches are impractical or when the government needs to attract nontraditional defense contractors.
Hangar renovation work under NAICS 236220 generally involves structural modifications, systems upgrades, and potentially specialized features to support aircraft operations and maintenance. For a Special Operations Support hangar, this may include reinforced flooring, specialized utilities, secure communications infrastructure, climate control for sensitive equipment, and hangar door modifications—see the solicitation for specific technical requirements.

Who can bid
This solicitation is full and open competition with no small-business set-aside, meaning any qualified contractor—large or small—may submit a proposal. NAICS 236220 has a size standard of $47.5 million in average annual receipts.
Because this is an Other Transaction (OT) solicitation, eligibility may differ from standard FAR-based contracts. OTs for prototypes or research and development often seek nontraditional defense contractors—defined as entities not currently performing substantial work under DoD contracts. The progressive design-build format also means the government likely values demonstrated design-build experience, collaborative project delivery methods, and qualifications over low-bid pricing at this stage.
If your business is small, you may compete against larger firms. Consider whether you qualify as a nontraditional defense contractor or can partner with one, as OT provisions sometimes favor such arrangements. Joint ventures and mentor-protégé relationships may be viable pathways—see the solicitation for any specific eligibility or teaming requirements.
How to put together a competitive bid
For progressive design-build solicitations, proposals typically emphasize qualifications, technical approach, and team capability rather than firm fixed pricing at the initial stage. Focus on:
Design-build credentials: Document completed projects of comparable scale and complexity, particularly military or aviation facilities. Highlight integrated design-construction teams and your collaborative process with government clients.
Progressive delivery experience: Detail how you manage early contractor involvement, target-value design, and transparent cost modeling. The government is buying a process as much as a product.
Security clearances and past performance: SOS hangar work may involve sensitive information; demonstrate personnel and facility clearances if applicable. Provide strong past-performance references from military construction projects.
OT-specific responsiveness: Review the solicitation's instructions carefully—OT proposals often follow commercial formats rather than standard government proposal structures. Address any requests for intellectual property arrangements, cost-sharing, or alternative technical concepts.
Teaming strategy: If you're a small firm lacking bonding capacity or specific technical expertise, identify potential teammates early. The progressive nature of this delivery method rewards integrated teams over fragmented submissions.
