Region 4 Slab Jacking Projects

The State of Colorado is requesting bids for Region 4 Slab Jacking Projects under IFB 27-201711, with bids due September 17, 2026 at 2 PM via BidNet Direct and a virtual public bid opening immediately following at 3:30 PM. Questions are due September 9, 2026 at 5 PM.

The scope involves lifting four identified locations with significant dips using Expanding Structural Polymer (ESP) injected beneath concrete slabs to stabilize and raise affected areas. Work sites are Highway 52, Highway 66, Weld County Road 8, and Interstate 70. The contract term runs from October 21, 2026 through June 30, 2027, with completion of all lifting work required by June 1, 2027. The State may extend the contract at its discretion.

Mandatory Phase 1 requirements follow a strict Pass/Fail evaluation and filter heavily on capability: five or more years of continuous business in concrete lifting and stabilization; at least two of three project references from DOT or public municipalities using ESP injection on bridge approaches or sleeper slabs; detailed work plans specifying drilling, injection parameters, and precision lift monitoring methodology; project schedules demonstrating June 1, 2027 completion; manufacturer Technical Data Sheets for ESP products; and equipment inventory verification. Phase 2 pricing proposals remain unopened until Phase 1 evaluations are complete. Awards will be made to the lowest responsive and responsible bidder.

Bid pricing must remain firm during the initial contract term and must include all fees for delivery, shipping, and installation. Pricing must use only the Rate Table provided in Attachment A; alternative formats result in rejection as non-responsive. The Point of Contact is David Pollitt, Purchasing Agent IV, at david.pollitt@state.co.us. The Intent to Award is estimated for publication September 22, 2026.
