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 contract award from $7,253,128.25 to $12,664,944.53. It authorizes 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. The change order addresses differing subsurface conditions, duct bank conflicts, contingency replenishment, and a concrete manhole substitution credit. The resolution was adopted by the Board of County Commissioners on 7/21/2026. The project is located in Commission District 2, represented by Commissioner Marleine Bastien, who is the Prime Sponsor. The project will extend critical wastewater infrastructure and replace undersized water mains serving industrial and commercial properties along NW 22nd Avenue. The improvements include installation of approximately 9,246 linear feet of sanitary sewer mains and 9,851 LF of ductile iron water main service lines. The project originated from Resolution No. R-597-13, which directed 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 original contract was awarded on November 22, 2021, ratified by the Board on March 15, 2022 via Resolution No. R-259-22, with a total award of $7,253,128.25, a duration of 750 calendar days, and a Contingency Time Allowance of 75 days. The Notice to Proceed was issued on June 1, 2022, establishing May 21, 2024 as the Substantial Completion Date and June 20, 2024 as the Final Completion Date. After this change order, the Substantial Completion Date is revised to February 15, 2027, and the Final Completion Date to March 17, 2027. The change order includes $4,680,600.00 for differing sub-surface conditions with a 908-calendar day extension, $595,409.58 for contingency replenishment, $167,731.70 for duct bank conflicts with a 92-calendar day extension, and a $31,925.00 credit for concrete manhole substitution. The contract was awarded with an 8 percent Small Business Enterprise Goods goal and an 18 percent SBE Construction goal. The SBE-Con goal is recommended to be removed from the project due to restrictive funding and fixed budget. No public comment or stakeholder sentiment is stated in the document.
