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: 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. It 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. The change order is driven by differing subsurface conditions (larger trenching requirements, additional restoration, unforeseen conflicts with communication and electrical duct banks), includes a credit for concrete manhole substitution, and replenishes the contract's Contingency Allowance. The project extends critical wastewater infrastructure and replaces undersized water mains serving industrial and commercial properties. The contract was awarded on November 22, 2021, ratified by the Board on March 15, 2022 via Resolution No. R-259-22, 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 from June 20, 2024 to March 17, 2027. The Board of County Commissioners adopted the resolution on July 21, 2026. The Infrastructure, Innovation & Technology Committee forwarded it with a favorable recommendation on June 10, 2026. The project is 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), leading to the Connect 2 Protect Program. The project includes approximately 9,246 linear feet of sanitary sewer mains and 9,851 LF of ductile iron water main service lines. The change order includes $4,680,600.00 for differing subsurface conditions (908-day extension), $595,409.58 for contingency replenishment, $167,731.70 for duct bank conflicts (92-day extension), and a $31,925.00 credit for concrete manhole substitution. The SBE-Con goal is recommended to be removed from the project. No public comment or stakeholder sentiment is stated in the document.
