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 1,000-calendar day time extension and increases the contract amount by $5,411,816.28, bringing the total from $7,253,128.25 to $12,664,944.53. The change order is driven by differing subsurface conditions (unstable sandy soils) requiring larger trenching and additional roadway restoration ($4,680,600.00, 908-day extension), duct bank conflicts requiring realignment of the gravity sewer main ($167,731.70, 92-day extension), replenishment of the Contingency Allowance ($595,409.58), and a credit for substituting concrete manholes for fiberglass ($31,925.00 savings). The project extends critical wastewater infrastructure and replaces undersized water mains serving industrial and commercial properties. 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 Infrastructure, Innovation & Technology Committee forwarded it to the BCC with a favorable recommendation on 6/10/2026. Agenda date is 7/21/2026. 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 to extend sanitary sewer service to the Miami-Dade Green Technology Corridor (GTC) under the Connect 2 Protect Program. Funding sources include WASD Revenue Bonds Sold, Water Connection Charges, Future WASD Revenue Bonds, BBC GOB Financing, and Florida Department of Environmental Protection Grant. The SBE-Con goal is recommended to be removed because SBE-Con firms were unable to perform at original bid prices and the Contractor could not secure substitutes; the Contractor will self-perform that portion. No public comment or stakeholder sentiment is stated in the document.
