Miami-Dade County Board of County Commissioners adopted Resolution R-750-26 (File Number 261434) on 9/1/2026, ratifying 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 increases the contract by $2,003,650.00 to replenish the contingency allowance and reallocates $1,629,590.00 in existing unused contract funds to address an overrun in Bid Item 7 for excavation, loading, hauling, and disposal of calcium carbonate residual. The project was declared an emergency on 11/12/2024 due to a breach of a sludge lagoon berm. The original contract was awarded on 2/14/2025 for $23,742,340.00 with a 540-calendar-day duration, ratified by the Board on 6/26/2025 via Resolution R-613-25, with Notice to Proceed issued 2/24/2025 and final completion date of 8/18/2026. The project is located at 6800 SW 87th Ave. in Commission District 10. The original estimated quantity of calcium carbonate residual was 175,000 cubic yards, and field conditions confirmed quantities exceeded this estimate. The change order reallocates funds from Bid Item 500 (Price Escalation, $601,095.00), Bid Item 505 (permits, fees, impact fees, inspections, $601,095.00), Bid Item 11 (new dike construction, $407,400.00), and Bid Item 503 (off-duty police officers, $20,000.00). The contingency was depleted due to unforeseen conditions including a leak at the North Lagoon, repairs to the truck wash station, upgrades to deteriorated catwalks, and higher hauling and disposal costs due to saturated material. Funding comes 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 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.
