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

Resolution approving Change Order No. 1 to Contract No. S-958 between Miami-Dade County and Lanzo Construction Co., Florida for the D2-C2 project: proposed 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 grants a 1,000-calendar day time extension and increases the contract amount by $5,411,816.28, bringing the total from $7,253,128.25 to $12,664,944.53. It also includes a credit for concrete manhole substitution and replenishes the contingency allowance. The project extends wastewater infrastructure and replaces undersized water mains in the Miami-Dade Green Technology Corridor. The resolution was adopted by the Board of County Commissioners on 7/21/2026, after being forwarded with a favorable recommendation by the Infrastructure, Innovation & Technology Committee on 6/10/2026. The project is located in Commission District 2, represented by Commissioner Marleine Bastien, who is the Prime Sponsor. The change order addresses differing subsurface conditions ($4,680,600.00, 908-day extension), duct bank conflicts ($167,731.70, 92-day extension), contingency replenishment ($595,409.58), and concrete manhole substitution savings ($31,925.00). 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 contract was originally 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 project is funded by WASD Revenue Bonds Sold, Water Connection Charges, Future WASD Revenue Bonds, BBC GOB Financing, and Florida Department of Environmental Protection Grant. The SBE-Con goal is recommended to be removed from the project because SBE-Con firms were unable to perform at original bid prices and no substitute was secured; the contractor will self-perform that portion of work. No public comment or stakeholder sentiment is stated in the document.
