Base Operations Support (BOS) Contracting
BOS contracts are large, multi-year awards (often 5-10 years with options) that bundle multiple facilities services:
- Building maintenance and repairs (HVAC, plumbing, electrical)
- Custodial and janitorial services
- Grounds maintenance and landscaping
- Utilities operations and energy management
- Pest control, waste management, and recycling
- Transportation and motor pool support
Set-aside opportunities exist, but large BOS contracts often exceed small business size standards. Bundling analysis is required under the Small Business Act.
