NASA is preparing MACC-III (Regionalized Multiple Award Construction Contract III), a $1 billion IDIQ for construction services across five NASA centers. With 30 anticipated awards and a competition structure that includes both small business set-aside and unrestricted tracks, MACC-III provides construction firms with access to NASA focused facility construction and renovation projects.
This RFP is expected in March 2026, with awards anticipated in October 2026. MACC-III will support construction projects at Kennedy Space Center, Johnson Space Center (including White Sands Test Facility), Marshall Space Flight Center (including Michoud Assembly Facility), Stennis Space Center, and associated facilities. Stennis Space Center will administer the basic contracts, while each center will issue and administer task orders.

WHY NASA MACC-III MATTERS
MACC-III consolidates construction services across five major NASA centers, providing contractors with access to facility construction, renovation, and infrastructure projects supporting space exploration and research missions. The regionalized structure allows NASA to award contracts tailored to the specific needs and project types at each center, with Stennis Space Center administering the basic IDIQ contracts while each individual center issues and administers task orders for their specific requirements.
With 30 anticipated awards across multiple NAICS codes and bonding capacity levels, MACC-III provides broader access than typical construction IDIQs. The mixed competition structure—including both small business set-aside and unrestricted tracks—ensures dedicated opportunities for small construction firms while maintaining competition for larger, more complex projects requiring higher bonding capacity.
The current MACC-II contracts, which have been extended through 2026-2027, include 24 contractors across various small business categories (WOSB, HUBZone, SDVOSB, 8(a)) and unrestricted pools, demonstrating NASA’s commitment to diverse small business participation.
WHO SHOULD CONSIDER NASA MACC-III
MACC-III is designed for construction firms with experience in institutional and industrial building construction and the bonding capacity to support NASA facility projects. Firms with capabilities in the following areas should evaluate whether their past performance and bonding capacity align with NASA’s requirements:
- Industrial building construction
- Commercial and institutional building construction
- Water and sewer line construction
- Power and communication line construction
- Heavy and civil engineering construction
- Facility renovation and modernization
- New building construction
- Design-build projects
- LEED (Leadership in Energy and Environmental Design) projects
- Building Information Modeling (BIM)
- Demolition and site restoration
- Emergency response and natural disaster recovery
Firms must possess bonding capacity appropriate to their intended competition track: small businesses require minimum $10M single project/$30M aggregate bonding, while unrestricted contractors require minimum $100M single project/$1B aggregate bonding.
HOW OST CAN HELP
OST supports construction firms pursuing complex federal facility construction contracts with:
- Bonding capacity assessment: Determine which competition track (small business or unrestricted) aligns with your current bonding capacity
- Capability alignment: Assess which NAICS codes and construction types match your past performance and technical capabilities
- Past performance strategy: Document relevant construction experience from federal, state, or commercial projects
- Teaming strategy: Connect with firms that have complementary capabilities, bonding capacity, or geographic presence at target NASA centers
- Proposal development: Technical approach, past performance narratives, and compliance
If you’re evaluating whether NASA MACC-III aligns with your firm’s capabilities, or need support developing a competitive proposal, we can help. If this interests you, please book a call with OST Partner and President Bill Schalik via the button below.
