Resolution R-750-26 ratifies 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 was declared an emergency on November 12, 2024, due to a breach of a sludge lagoon berm. 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 February 24, 2025, making the final completion date August 18, 2026. The original estimated quantity of calcium carbonate residual was 175,000 cubic yards, but field conditions confirmed quantities exceeded this estimate. The resolution was adopted on September 1, 2026.
