2027 Portland Cement Concrete Materials

Ada County Highway District (ACHD) in Boise is requesting competitive bids on Portland Cement Concrete materials for 2027 under ITB with bids due October 14, 2026 at 3:00 p.m. via the ACHD eProcurement portal. The solicitation carries no set-asides or local preferences; it is open to any qualified supplier, including foreign entities that provide proof of Idaho business registration compliance prior to award.

The scope is 1,100 cubic yards of Portland Cement Concrete, Class 3000 with 3/4" minus aggregate, split across two line items: 500 cubic yards for loads over four yards and 600 cubic yards for loads of four yards or less. All material must meet Idaho Standards for Public Works Construction (ISPWC) 2025 edition specifications and AASHTO M 85 Type I Portland cement. Delivery within Ada County must occur within 24 hours for orders of ten cubic yards or less and within 48 hours for larger orders. Standby time up to 30 minutes is included in unit pricing for loads exceeding four cubic yards. Optional additive materials (micro-synthetic fiber reinforcement, hot water, and water-reducing admixture) are available but do not factor into low-bid determination. Material delivery is via approved drum mixer trucks only.

Pricing is submitted on a unit cost basis per cubic yard for each line item. The contract period runs through December 31, 2027, with no renewal options specified. ACHD reserves the right to place multiple orders and extend the contract term throughout the agreement duration. The successful bidder must execute the agreement within 15 calendar days of award. Upon issuance of the Notice of Award, the supplier may be required to furnish supply, material, payment, and performance bonds equal to 100 percent of the total contract value, along with Comprehensive General Liability Insurance (minimum $100,000 per claim / $500,000 aggregate) and Motor Vehicle Insurance at identical limits.

Questions are due October 7, 2026 at 4:30 p.m., with responses provided by October 8 at 4:30 p.m. Sealed bids will be opened publicly via Zoom on October 14 at 3:00 p.m.
