Background
NIH’s Office of Research Facilities oversees the planning, construction, maintenance and operation of NIH facilities. This MACC is intended to support varied projects across its Maryland, North Carolina and Montana campuses through individual task orders.
The opportunity was previously identified as FY2025 Multiple Award Construction Contract and NIH FY2026 Multiple Award Construction Contract, with earlier identifiers NIHFY2025MACC and SSNMACC2026. This existing profile has been updated to the current solicitation identity rather than creating a duplicate.
Requirements and Pursuit Considerations
The source describes general construction across multiple disciplines:
- Maintenance, repair, painting, alterations, renovations, demolition and new construction.
- Architectural, mechanical, electrical, plumbing and HVAC work.
- Civil, earthwork, fencing, structural work, steel fabrication, welding and roofing.
- Sustainable construction, design-bid-build and design-build projects.
Task orders may combine disciplines and vary in size, scope and complexity. Each task order’s requirements, specifications and drawings control the work.
The source reports a seed-project construction magnitude of $500,000–$1 million. Only MACC awardees are eligible for that task order, and its award is subject to availability of funds.
