Board of County Commissioners · 2026-07-21 · resolution

Resolution ratifying Change Order No. 1 to Contract No. S-930B between Miami-Dade County and Daniel O'Connell's Sons, Inc. for the ST-2D-B South District Wastewater Treatment Plant (SDWWTP) Substations 5/6 and 15/16 project. The change order grants a 622-calendar day non-compensable time extension with no additional fiscal impact. The project involves construction of two new electrical substations and installation of new electrical equipment duct banks and associated infrastructure to redistribute electrical loads of oxygenation trains 1 through 8. The project will increase the plant's permitted average annual daily flow from 112.5 to 131 million gallons per day (MGD) and peak flow capacity from 285 MGD to 305 MGD. The contract was awarded on March 1, 2022, for $21,805,340.00, ratified by Resolution No. R-491-22 on May 17, 2022. The Notice to Proceed was issued May 2, 2022. Change Order No. 1 extends the Substantial Completion Date from June 10, 2023 to February 21, 2025, and the Final Completion Date from July 22, 2023 to April 4, 2025. The delays were due to extended fabrication and delivery delays of major electrical equipment (415-calendar day delay) and required shutdowns for installation and termination of new low voltage (480V) feeders serving existing facilities, including Headworks Building No. 1 (207-calendar day delay). The project is located at WASD's SDWWTP in Commission District 8, represented by Commissioner Danielle Cohen Higgins. The resolution was adopted by the Board of County Commissioners on July 21, 2026. No public comment or stakeholder sentiment is stated in the document.
