2026 Arterial and Collector Capital Maintenance

Ada County Highway District is soliciting unit-price bids under Invitation to Bid Contract CT227-09 (Project 524019) for the 2026 Arterial and Collector Capital Maintenance on Poplar Street from Curtis Road to Cole Road in Boise, Idaho, with written questions due November 13, 2026. The ITB specifies no set-asides, and no federal aid funds finance the project.

Bidders must hold a current Idaho Public Works Contractor License (Type 1, 2, or 4), with Type 4 licenses requiring roadway specialty categories. The contract requires 95 percent Idaho-resident employment, or a ten percent non-resident allowance for employers with fifty or fewer employees, along with prevailing wage and tax compliance.

Scope includes pavement rehabilitation and asphalt improvements, irrigation and stormwater work, ADA pedestrian ramp upgrades, sidewalk gap filling, traffic circles at Eldorado Lane and Liberty Street, an enhanced pedestrian crossing at Poplar Street and Cole Road, multi-use pathway improvements to Curtis Road, wayfinding signage, sharrows, and a raised concrete intersection at Poplar Street and Fisk Street. The bid schedule exceeds 100 line items, including 9,700 cubic yards of excavation, 2,259 linear feet of 12-inch PVC storm drain, 2,752 square yards of concrete sidewalk, and 4,550 tons of asphalt. Nine utility companies operate within the project limits, and utility relocations require approximately 150 working days from Notice to Proceed.

The Engineer's Estimate serves as the baseline for award evaluation, and ACHD may reject all bids exceeding it by more than ten percent. Award goes to the apparent low-cost responsive bidder. Final contract amount depends on actual quantities at proposed unit prices. Bid security equals ten percent of the total proposal amount, provided by certified check, cashier's check, or bid bond from an Idaho-authorized surety. The apparent low bidder must furnish performance and labor and material payment bonds equal to the full contract price, plus statutory workers' compensation, $1 million employer's liability, $2 million commercial general liability, and $2 million automobile liability insurance. Liquidated damages are $2,000 per calendar day.

Questions are due November 13, 2026 through the ACHD eProcurement portal. Electronic sealed bids are due 3:00 p.m. on November 18, 2026, with public opening via Zoom. Irrigation and bridge work must finish by March 15, 2027, and all other work by October 8, 2027, contingent on Notice to Proceed on or about January 4, 2027.
