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, which includes 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 time extension of 1,000 calendar days and increases the contract amount by $5,411,816.28, bringing the total contract award from $7,253,128.25 to $12,664,944.53. The resolution authorizes the use of funds from the Building Better Communities General Obligation Bond (GOB) Program Project No. 17-Countrywide Water and Sewer System Enhancements to pay in part for the extension of wastewater services along NW 22nd Avenue, and authorizes the County Mayor or designee to execute Change Order No. 1. The change order addresses differing subsurface conditions resulting in larger trenching requirements and additional restoration ($4,680,600.00, 908-day extension), unforeseen conflicts with communication and electrical duct banks ($167,731.70, 92-day extension), replenishes the Contract's Contingency Allowance ($595,409.58), and includes a credit for substituting concrete manholes for fiberglass ($31,925.00 savings). The project was approved via Resolution No. R-259-22 and originated from Resolution No. R-597-13, which directed the development of a plan to extend sanitary sewer service to commercial and industrial parcels within the Miami-Dade Green Technology Corridor (GTC). The project includes installation of approximately 9,246 linear feet of sanitary sewer mains and 9,851 LF of ductile iron water main service lines. The contract was awarded on November 22, 2021, ratified by the Board on March 15, 2022, with a Notice to Proceed issued on June 1, 2022. The Substantial Completion Date will be revised from May 21, 2024 to February 15, 2027, and the Final Completion Date from June 20, 2024 to March 17, 2027. The resolution was adopted by the Board of County Commissioners on July 21, 2026, after being forwarded with a favorable recommendation from the Infrastructure, Innovation & Technology Committee on June 10, 2026. The project is located in Commission District 2, represented by Commissioner Marleine Bastien, who is the Prime Sponsor. The fiscal impact is funded out of WASD Revenue Bonds Sold, Water Connection Charges, Future WASD Revenue Bonds, BBC GOB Financing, and Florida Department of Environmental Protection Grant, with no impact to the General Fund. The project is in WASD's Fiscal Year 2025-2026 Adopted Budget 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 contract was awarded with an 8 percent Small Business Enterprise (SBE) - Goods goal and an 18 percent SBE - Construction (SBE-Con) goal. The SBE-Con goal is recommended to be removed from the project due to the restrictive nature of the project funding and fixed budget, and because the Contractor will be self-performing this portion of the work.
