CHANGE ORDER #1 LANZO CONSTRUCTION (S-958)

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 change order is driven by differing subsurface conditions, unforeseen duct bank conflicts, and includes a credit for concrete manhole substitution and replenishment of the contingency allowance. The project extends critical wastewater infrastructure and replaces undersized water mains serving industrial and commercial properties. The Board adopted the resolution on July 21, 2026. The project was forwarded to the Board with a favorable recommendation from the Infrastructure, Innovation & Technology Committee on June 10, 2026. The contract was originally awarded on November 22, 2021 and ratified by the Board on March 15, 2022 via Resolution No. R-259-22. The Notice to Proceed was issued 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 project is located in Commission District 2, represented by Commissioner Marleine Bastien, who is the Prime Sponsor. The project 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 Miami-Dade Water and Sewer Department created the Connect 2 Protect Program to expand access to sanitary sewer service for properties reliant on septic systems. The additional 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. 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 Contract was awarded with an eight percent Small Business Enterprise - Goods (SBE-Goods) goal and an 18 percent SBE - Construction (SBE-Con) goal. The Prime Contractor has exceeded the SBE-Goods goal. The SBE-Con goal was to be met through the performance of poured concrete foundation and structure work, and highway street and bridge construction work. After award, the SBE-Con firms reported they were unable to perform at their original bid prices. The Contractor solicited bids from SBE-Con firms to substitute and submitted documentation indicating it was unable to secure a substitute SBE-Con firm. 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 the Contractor will be self-performing this portion of the work and the SBE-Con measure is no longer applicable. Based on the justifications provided, the Project is in compliance. The change order includes a cost of $4,680,600.00 and a 908-calendar day non-compensable time extension for differing sub-surface conditions, a contingency replenishment of $595,409.58, a cost of $167,731.70 and a 92-calendar day non-compensable time extension for duct bank conflicts, and a contract savings of $31,925.00 for concrete manhole substitution. 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. WASD's Deputy Director of Planning, Regulatory Compliance and Capital Infrastructure, Marisela Aranguiz-Cueto, P.E., will oversee implementation.
