Board of County Commissioners · 2026-07-21 · resolution

Miami-Dade County Board of County Commissioners adopted Resolution R-645-26 (File Number 260948) approving Change Order No. 1 to Contract No. S-958 with Lanzo Construction Co., Florida. The change order increases the contract amount by $5,411,816.28, from $7,253,128.25 to $12,664,944.53, and grants a 1,000-calendar day non-compensable time extension. The project involves installation of 16-inch, 12-inch, and 8-inch DI water main and 10-inch and 8-inch DI gravity sewer along NW 22nd Avenue from NW 79th Street to NW 90th Street, and an 8-inch DI force main along NW 87th Street. The change order addresses differing subsurface conditions, duct bank conflicts, concrete manhole substitution, and replenishes the contingency allowance. The project is funded in part by the Building Better Communities General Obligation Bond (GOB) Program Project No. 17-Countrywide Water and Sewer System Enhancements. The Infrastructure, Innovation & Technology Committee forwarded the item with a favorable recommendation on 6/10/2026, and the Board adopted it on 7/21/2026. The project is located in Commission District 2, represented by Commissioner Marleine Bastien, who is the Prime Sponsor. The original contract was awarded on November 22, 2021, ratified by the Board on March 15, 2022 via Resolution No. R-259-22, with a Notice to Proceed issued on June 1, 2022. The Substantial Completion Date is revised from May 21, 2024 to February 15, 2027, and the Final Completion Date from June 20, 2024 to March 17, 2027. The change order includes $4,680,600.00 for differing subsurface conditions with a 908-calendar day extension, $595,409.58 for contingency replenishment, $167,731.70 for duct bank conflicts with a 92-calendar day extension, and a $31,925.00 credit for concrete manhole substitution. The project extends critical wastewater infrastructure and replaces undersized water mains serving industrial and commercial properties along NW 22nd Avenue. The project originated from Resolution No. R-597-13, which directed a plan to extend sanitary sewer service to commercial and industrial parcels within the Miami-Dade Green Technology Corridor (GTC), leading to the Connect 2 Protect Program. The contract was awarded with an 8 percent Small Business Enterprise Goods (SBE-Goods) goal and an 18 percent SBE Construction (SBE-Con) goal. The SBE-Goods goal was exceeded, but the SBE-Con goal is recommended to be removed because SBE-Con firms were unable to perform at original bid prices and no substitute was secured. The project is in WASD's Fiscal Year 2025-2026 Adopted Budget and Multi-Year Capital Plan under Water Reset Program - Small Diameter Water Mains Replacement, Program #2000000072, Volume #3, Page #123 and Commercial and Industrial Corridors - Extension of Sewer System (Connect to Protect), Program #967090, Volume #3, Page #103. The additional fiscal impact is funded out of WASD Revenue Bonds Sold, Water Connection Charges, and Future WASD Revenue Bonds, BBC GOB Financing, and Florida Department of Environmental Protection Grant. There is no impact to the General Fund. WASD's Deputy Director of Planning, Regulatory Compliance and Capital Infrastructure, Marisela Aranguiz-Cueto, P.E., will oversee implementation.
