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 was awarded on February 14, 2025, ratified by the Board on June 26, 2025, via Resolution No. R-613-25, with a total contract award of $23,742,340.00 and a 540-calendar-day duration. The Notice to Proceed was issued February 24, 2025, making the final completion date August 18, 2026. The emergency was declared on November 12, 2024, due to a breach of a sludge lagoon berm. The original estimated quantity of calcium carbonate residual was 175,000 cubic yards, which has been exceeded. The agenda date is September 1, 2026, agenda item number 8O2. The file number is 261434. The item was introduced on August 14, 2026. The status is 'In Draft'. The staff recommendation is to ratify the change order. 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 project is being performed at WASD's AOWTP, located at 6800 SW 87th Ave., in Commission District 10, represented by Chairman Anthony Rodriguez. The contract was awarded pursuant to Section 2-8.2.12 of the Code of Miami-Dade County, Florida (WASD's Acceleration Ordinance). The change order reallocates funds from Bid Item 500 (Price Escalation) $601,095.00, Bid Item 505 (permits, fees, impact fees and inspections) $601,095.00, Bid Item 11 (construction of a new dike and improvement to existing dikes) $407,400.00, and Bid Item 503 (reimbursement of off-duty police officers) $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. WASD and the Contractor continue to validate remaining excavation quantities, and a subsequent reconciliation change order may be presented at contract closeout if necessary. Small Business Enterprise measures did not apply to the contract. No public comment or stakeholder sentiment is stated in the document.
