Services are performed daily, Monday through Saturday, at 19150 NW 8th Avenue, Miami Gardens, Florida 33169. The sludge has solids concentration ranging from 30% to 50%. The estimated volume is approximately 51,000 pounds (25.5 net tons) per load, averaging 85 to 90 loads monthly (approximately four loads per day), though this quantity is not guaranteed and is subject to change based on facility operating conditions. Historical 12-month data (April 2025 through May 2026) shows monthly tonnage ranging between 1,579 and 2,694 net tons, with an estimated annual volume of approximately 27,000 tons. Sludge characterization testing indicates the presence of PFAS at low concentrations (18 μg/kg 6:2 FTS); all other tested analytes were not detected or below reporting limits.

Bidders must provide all-inclusive pricing covering labor, materials, equipment, supplies, permits, and all other necessary components. Pricing must remain firm during the three-year initial term and may be adjusted at renewal (maximum 3% annually) based on the Consumer Price Index for All Urban Consumers.

The contract term is three years with two optional one-year renewal periods. The City reserves the right to terminate for convenience with 15 days' written notice or for cause following a 10-business-day cure period. Bidders must provide three references from governmental agencies, public, non-profit, or for-profit entities. Award will be made to the lowest priced responsive, responsible bidder meeting minimum qualifications.
