Bidders may propose under one of three product groups: Group 1 for 8-inch or finer chips, Group 2 for 4-inch or finer chips, or Group 3 for variable sizes (50% at 8-inch, 40% at 4-inch, and 10% at 0.5-inch). The anticipated annual volume is approximately 240,000 cubic yards with grinding occurring quarterly; the immediate current need is 50,000 cubic yards. The contractor must commence grinding within two weeks of notification when stockpiles reach 20,000 cubic yards and complete work within four weeks unless weather-delayed, with liquidated damages of $100 per day for delays beyond the completion date (exempt for the first grinding cycle).

Qualification requirements include a minimum of three years' experience in similar services and commercial general liability insurance with minimum limits of $1,000,000 per occurrence and $2,000,000 annual aggregate, plus comprehensive automobile liability coverage and workers' compensation meeting statutory requirements. The contractor must secure all environmental permits and provide equipment (loader/excavator and horizontal grinder), ensure ANSI and OSHA safety compliance, and assume liability for property damage. Subcontracting is prohibited without written City approval and considered only if specialized equipment is necessary.

Pricing shall be submitted on a cost-per-cubic-yard basis with mobilization and mileage costs included. Payment is remitted within Net 15 or Net 30 days following invoice submission with supporting documentation of completed volumes signed by both parties. The contract term is one year with four optional one-year renewal periods. Award will be made to the lowest and best total bid for the group selected. City Council approval is tentatively scheduled for August 4, 2026.
