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 a 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-Countywide 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, duct bank conflicts, and includes a credit for concrete manhole substitution. The project was approved by the Board 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 is being performed primarily along NW 22nd Avenue from NW 79th Street to NW 90th Street, located in Commission District 2. The change order 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 contract was awarded on November 22, 2021, ratified by the Board on March 15, 2022, and the Notice to Proceed was issued on June 1, 2022. The Substantial Completion Date is revised from May 21, 2024 to February 15, 2027, and the Final Completion Date is revised from June 20, 2024 to March 17, 2027. 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. 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 change order includes $4,680,600.00 for differing sub-surface conditions with a 908-calendar day time extension, $595,409.58 for contingency replenishment, $167,731.70 for duct bank conflicts with a 92-calendar day time extension, and a contract savings of $31,925.00 for concrete manhole substitution. The contract was awarded with an eight percent Small Business Enterprise (SBE) - Goods goal and an 18 percent SBE - Construction (SBE-Con) goal. The Prime Contractor has exceeded the SBE-Goods goal. WASD is recommending the SBE-Con goal be removed from the Project due to the restrictive nature of the Project funding and the fixed budget available. WASD indicated that the Contractor will be self-performing this portion of the work and that the SBE-Con measure is no longer applicable to this Project. Based on the justifications provided, the Project is in compliance.
