Summary of 2147 Eckert Utility Hang Plan Sheet

This is a utility coordination plan sheet prepared for the Ada County Highway District's Eckert Road Bridges 2147 and 2148 project, which encompasses demolition and reconstruction of two bridges spanning the Boise River and Ridenbaugh Canal in Boise, Idaho. The project scope includes construction of new prestressed concrete girder bridges (364 feet over the Boise River with three spans; 91 feet over Ridenbaugh Canal with one span), a single-lane roundabout at the Eckert Road and Boise Avenue intersection, a multi-use pathway, a Greenbelt underpass, roadway reconstruction, and associated infrastructure improvements. Sealed bids are due August 19, 2026, at 3:00 p.m., with questions due August 14, 2026, at 12:00 p.m. The Notice to Proceed is anticipated October 1, 2026, with substantial completion required by June 21, 2028 (approximately 20 months). Contract award is anticipated within 60 calendar days of bid opening.

The estimated contract value exceeds $25 million, with bid security of 10 percent of the total proposal amount required as certified check, cashier's check, or bid bond. The successful bidder must furnish Performance and Labor/Material Payment Bonds equal to the full contract price and maintain commercial general liability insurance of $2 million, automobile liability of $2 million, and statutory workers' compensation with employer's liability of $1 million. Liquidated damages of $12,000 per calendar day apply for failure to meet completion deadlines. Bidders must be licensed Idaho Public Works Contractors (Type 1, 2, or 4) and submit unit-price proposals. Nine utility companies require coordination, with utility relocations and adjustments potentially requiring approximately 160 working days from Notice to Proceed. No federal aid funds finance the project; all applicable state and local sales and use taxes must be included in bid prices. Contractors domiciled outside Idaho must bid at a percentage less than the lowest Idaho-domiciled bid per Idaho Code sections 67-2348 and 67-2349.
