Board of County Commissioners · 2026-09-01 · resolution

Resolution to ratify Change Order No. 1 to Contract No. S-20331 between Miami-Dade County and Lanzo Construction Co. Florida for an emergency project at the Alexander Orr Water Treatment Plant. The change order reallocates $1,629,590.00 in existing contract funds to address a documented overrun in Bid Item 7 for excavation, loading, hauling, and disposal of calcium carbonate residual, and increases the contract by $2,003,650.00 to replenish the contingency allowance. The project is located at 6800 SW 87th Ave. The original contract award was $23,742,340.00 with a contingency allowance of $2,003,650.00 and a duration of 540 calendar days. The Notice to Proceed was issued on February 24, 2025, making the final completion date August 18, 2026. The original estimated quantity of calcium carbonate residual was 175,000 cubic yards, and field conditions confirmed quantities exceeded this estimate. The emergency was declared on November 12, 2024, due to a breach of a sludge lagoon berm. The contract was awarded on February 14, 2025, and ratified by the Board on June 26, 2025, via Resolution No. R-613-25. The agenda date is September 1, 2026, with an agenda item number of 8O2. The item was introduced on August 14, 2026. The status is 'In Draft' and pending BCC assignment. The fiscal impact is funded from WASD Revenue Bonds Sold, Future Revenue Bonds and Proprietary Funds, with no impact to the General Fund. The project is in WASD's Fiscal Year 2025-26 Adopted Budget and Multi-Year Capital Plan under Water Reset Program - Water Treatment Plant - Alexander Orr, Jr. Expansion, Program #9650031, Volume #3, Page #123 and under Contractual Services, Volume #3, Page #100. The reallocated line items include Bid Item 500 Price Escalation (Dedicated Allowance) $601,095.00, Bid Item 505 for costs of required permits, fees, impact fees and inspections $601,095.00, Bid Item 11 for construction of a new dike and improvement to existing dikes $407,400.00, and Bid Item 503 for reimbursement of off-duty police officers (Dedicated Allowance) $20,000.00. The contingency allowance was depleted due to unforeseen conditions including emergency repairs to a leak at the North Lagoon, repairs to the truck wash station, upgrades and additional repairs to deteriorated catwalks, and higher hauling and disposal costs due to saturated material. The project is in Commission District 10, represented by Chairman Anthony Rodriguez. The staff recommendation is to ratify Change Order No. 1.
