2026 Arterial and Collector Capital Maintenance

The 2026 Arterial and Collector Capital Maintenance project (CT227-09) is a solicitation by the Ada County Highway District (ACHD) for capital maintenance work located from Poplar Street to Cole Road to Curtis Road in Idaho. The scope of work includes excavation, removal of obstructions, culvert crossing backfill, and the coordination of landscape removal and replacement for adjacent property owners. All work must adhere to ACHD Plan Sheets 1-71, Special Provisions, and Cross Sections. The contract requires strict adherence to OSHA excavation and trenching standards, ADA access requirements during construction, and specific pavement marking and roadside signage protocols, including the salvage of removed signs for delivery to ACHD. The award will be granted to the lowest cost and responsive bidder, though ACHD reserves the right to reject all bids if they exceed the Engineer's Estimate by more than ten percent. Bidders must submit proposals via the ACHD eProcurement Portal by November 18, 2026, at 3:00pm. A bid security of ten percent of the total proposal amount is required via certified check, cashier's check, or bid bond. The successful contractor is responsible for quality control and must utilize Idaho Transportation Department approved laboratories and certified personnel for testing. Final project acceptance is determined by ACHD based on conformance to approved plans and specifications.
