RECOMMENDATION

The Administration recommends approving the Resolution.

BACKGROUND/HISTORY

On June 22, 2022, the Mayor and City Commission (”City Commission”) authorized the Administration to enter into negotiations with Hazen and Sawyer, P.C. (“Hazen”) and A&P Consulting Transportation Engineers Corp. (“A&P”) pursuant to Request for Proposals (RFQ) No. 2022-122-ND for Engineering Services for Water and Wastewater Projects.

On February 8, 2023, the City and A&P entered into an agreement (the “Agreement”) having an initial term of three (3) years, with two (2) one-year renewal terms.

On April 28, 2023, the City Commission approved a request for approval of routine renewals, service orders, change orders, or contract amendments for City-awarded contracts, including the assignment of the Agreement from A&P to CHA Consulting, Inc. (“CHA”), following acquisition of

A&P by CHA in February 2021, thereby assigning the rights, titles, interests, and obligations of A&P pursuant to the Agreement to CHA.

The subject service order involves the design, permitting, and post-design services necessary for a new sanitary sewer gravity main and a new water distribution system in the La Gorce and Lakeview neighborhoods, along with a new sanitary sewer force main to connect to the future Sanitary Sewer Pump Station 16 (“SSPS 16”)

The La Gorce and Lakeview Water & Sewer Improvements Project (the “Project”) is a priority infrastructure initiative aimed at addressing the aging and insufficient utility infrastructure in the La Gorce and Lakeview neighborhoods.

The Project's goal is to design the replacement of outdated sewer infrastructure and relocate it from backyard residential easements to the public right-of-way, ensuring safety, reliability, and reducing the impact on residences during future maintenance and repairs.

The City has conducted several citywide studies to identify necessary improvements throughout its infrastructure. This Project area is recognized in the City of Miami Beach Sewer System Master Plan as project area S-04, evaluated as the highest priority for Gravity Main replacements.

Additionally, the City of Miami Beach Water System Master Plan indicates that the water infrastructure in this area has a high probability of failure (POF), based on a composite score of remaining useful life and historical water break data.

The Sewer Force Main component is essential for the discharge of the future SSPS 16, which will collect Sewer Gravity flows from the Lake View Subdivision and the south section of North Bay Road in the Project area.

CHA provided a proposal (Attachment A), to conduct data gathering, prepare design drawings, develop specifications, obtain permits, and offer post-design support services in the total not-to- exceed amount of $2,361,425.83, to be completed under Agreement 2022-122-ND for Engineering Services for Water and Wastewater System Projects. Public Works has reviewed the proposal and finds it fair and reasonable.

Upon completion, the Project will enhance water and sewer services in the La Gorce and Lakeview neighborhoods.

This investment will improve system reliability, enhance public health and safety, ensure compatibility with future sewer infrastructure, and support future growth.

Accordingly, the Administration recommends that the Mayor and City Commission authorize the service order for design and post-design services for the Project in the not to exceed amount of $2,361,425.83.

FISCAL IMPACT STATEMENT $2,361,425.83 418-0815-061357-29-418-000-00-00-00-20526 Design-Capital Contracts

The total project budget for design services is $2,361,425.83. This project will provide a cost estimate for the proposed infrastructure improvements throughout the design phase, with construction costs estimated at $21,200,000.00.

This project is funded by the City’s Operating Funds for Water & Sewer Capital Projects.
