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

Resolution 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 reallocates $1,629,590.00 in existing contract funds to address an 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 involves operational and resiliency improvements to the calcium carbonate lagoon and softeners. 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, with a final completion date of August 18, 2026. The emergency was declared on November 12, 2024, due to a breach of a sludge lagoon berm causing loss of sludge and backwash water disposal capacity. The original estimated quantity of calcium carbonate residual removal was 175,000 cubic yards, which was exceeded due to saturated material and differing site conditions. The resolution was adopted on September 1, 2026. No public comment or stakeholder sentiment is stated in the document.
