YELL 338223 - Bridge Preservation

The Department of the Interior National Park Service seeks bridge preservation work at three Yellowstone National Park locations (Lava Creek Bridge, Thumb Creek Bridge, and Unnamed Creek Bridge), with proposals due October 30 and pre-proposal questions due October 15. This is a small business set-aside with an estimated price range of $1,000,000 to $5,000,000 and a 155-day firm fixed-price completion timeline following notice to proceed.

Place of performance is Teton County, Wyoming (Yellowstone National Park). The NAICS code is 237310 (Highway, Street, and Bridge Construction); the PSC is Z2LB (Repair Or Alteration Of Highways/Roads/Streets/Bridges/Railways). Scope encompasses concrete spall repair, masonry repointing, expansion joint replacement and sealing, hydro-demolition, modified concrete overlays, railing restoration and painting, asphalt paving, pavement markings, riprap placement for scour mitigation, stream diversion, erosion control, and traffic control across both in-water and out-of-water activities.

The contractor must perform at least 15 percent of total work with its own organization. Liquidated damages are assessed at $2,132 per calendar day of delay. Performance and payment bonds are required at 100 percent of contract price. All three bridges tested positive for lead-based paint.

Critical operational constraints include restricted work hours (7:00 a.m. to 7:00 p.m. Monday–Friday, or one hour before sunset, whichever is sooner; weekend and early morning work require contracting officer approval), single-lane traffic maintenance with 10-minute maximum hold times at two bridges, and four weeks advance notice for lane closures. Wildlife protocols mandate 650-foot suspension distance for bears or wolves, cutthroat trout spawning avoidance (April 15–July 15 at Thumb Creek), and immediate work suspension upon discovery of cultural resources.

All work must comply with Davis-Bacon prevailing wage rates and federal environmental permits including Clean Water Act Section 401 certification and U.S. Army Corps of Engineers Nationwide Permit authorizations. Evaluation uses a best value tradeoff approach weighing technical approach, project experience, key personnel qualifications, and past performance as primary factors, with price as secondary.

Amendment 0001 (effective September 24) corrected the pre-proposal question due date to October 15, 2026, at 2:00 p.m. Mountain Time. Amendment 0002 (effective October 13) posted supplementary documentation including pre-proposal meeting attendee list, transcripts, presentation slides, and revised 100% stamped and as-built drawings for all three bridges. Neither amendment extends the proposal deadline.
