On March 18, 2020, the Mayor and City Commission accepted the five-year critical needs capital plan for the City’s water and wastewater system for the design and construction of critical utility infrastructure projects.

On March 25, 2022, the Mayor and City Commission awarded and authorized the execution of the Agreement with CHA Consultants, Inc. (Formerly A&P Consulting Transportation Engineers, Corp.) for the Engineering Services for Water and Wastewater Projects (RFQ) No. 2022-122-ND.

On February 8, 2023, the City and CHA Consultants, Inc. (Formerly A&P Consulting Transportation Engineers, Corp.) entered into an Agreement for the Engineering Services for Water and Wastewater Projects (RFQ) No. 2022-122-ND, having an initial term of three (3) years, with two (2) one-year renewal terms.

On April 28, 2023, the City Commission approved item C2J, which included the Assignment of the Agreement from A&P Consulting Transportation Engineers, Corp. to CHA Consulting, Inc., thereby assigning the rights, titles, interest, and obligations of the Agreement (RFQ) No. 2022-122-ND from A&P Consulting Transportation Engineers, Corp.to CHA Consulting, Inc.

The tasks for Work Order 2 entail the design, permitting, and post permitting services for the replacement of the Normandy Isles Water Main from the Miami-Dade County Water Meter to the Normandy Isles Water Booster Station which involves replacing the piping, fixtures, and interconnections with the Normandy Isles infrastructure.

The Normandy Isles Water Main Replacement Project is a priority water infrastructure project in the Normandy Isles Neighborhood. The project intention is to design the replacement of aging water infrastructure, ensuring safety and reliability, in accordance with the City of Miami Beach Water System Master Plan. This water main is eighty years old, one of the oldest in the City, and is one of five water supply interconnections with the Miami-Dade Water and Sewer Department, transmitting water into distribution lines for Normandy Isles and into the Normandy Isles Water Booster, to transmit high water pressure to other neighborhoods in North Beach. The primary objective of this replacement project is to avoid the failure of one of City of Miami Beach’s most critical sections of water infrastructure.

The City has conducted several Citywide studies to identify improvements needed throughout its infrastructure: The City’s 2019 Water Master Plan, completed by Hazen and Sawyer, P.C, identified the need for the Normandy Isles 30-inch Water Main to undergo a replacement project at the current capacity. This plan determined the Normandy Isles 30-inch water main to have a high consequence of failure (CoF), a composite score calculated for each water main segment based on amount of flow, land use type, and proximity to major roads to determine the severity of impacts should the pipe fail. Additionally, transmission water main lines were scored as having a high CoF due to the potential social and health impacts if they fail. This same plan identified probability of failure (PoF) factors in all water main sections determined by remaining useful life, where most sections of the 30-inch Normandy Isles water main were classified as having a high PoF. The combination of a high PoF due to age and high CoF due to flow amount and it being a transmission line, leads to the prioritization of this water main replacement project as part of the 5-Year Water and Sewer Critical Needs Plan.

Procurement Selection Process:
