Fermilab seeks a qualified subcontractor for an IDIQ master subcontract covering on-call, scheduled, and emergency utilities excavation and repair services. Work will be performed at Fermilab in Batavia, IL, across a roughly 6,800-acre site in Kane and DuPage Counties with about 375 buildings and structures. Offerors must account for varied soil and terrain—including clay, fill, saturated soils, developed areas, prairie, woodlands, wetlands, and areas near ponds and waterways—in their technical approach, equipment selection, and pricing. The laboratory operates 24/7/365, so the work must support uninterrupted operations; the RFP and exhibits are available on Sam.gov.
