WHEREAS, the water main replacement segments include about 5,000 linear feet (LF) of
HDPE Pipe installed via horizontal directional drill (HDD) and about 450 LF of Ductile Iron Pipe

WHEREAS, the design has been closely coordinated with the Miami -Dade County
Department of Transportation and Public Works (DTPW)'s design for demolition and construction of
11 bridges along the Venetian Causeway (MD Public Project No. 2021001 1); and
WHEREAS, since these bridges were originally constructed in 1920's and have exceeded
their useful life, the replacement of the water and sewer pipes with new aerial crossings on the
bridges is no longer a feasible option; and
WHEREAS, the pipeline replacement project is anticipated to have a construction duration
of approximately 18 months, and is required to be completed prior to July 2025, when the DTPW
plans to initiate the construction of the Venetian Causeway Bridge Replacement Project; and
WHEREAS, pursuant to the City's "Management Policy for Internal Controls on Major
Construction Projects'', as approved pursuant to Resolution No. 2022-32047, projects with an
estimated construction cost greater than $5 million require the completion of an independent cost
estimate; however, in an effort to fast -track the implementation of this critical pipeline replacement
project and meet the DTPW's project schedule requirements, the City Manager recommends
waiving this City requirement and proceeding directly with the issuance of a competitive bid for the
Venetian Causeway Water and Sanitary Sewer Mains Replacement Project (Phase 2), finding that
said waiver is in the best interest of the City.
NOW, THEREFORE, BE IT DULY RESOLVED BY THE MAYOR AND CITY COMMISSION
OF THE CITY OF MIAMI BEACH, FLORIDA, that the Mayor and City Commission hereby accept
the recommendation of the City Manager and waive the independent cost estimate requirement of
the '"Management Policy for Internal Controls on Major Construction Projects", approved pursuant to

RECOMMENDATION
The Administration recommends approving the Resolution
BACKGROUND/HISTORY
The City of Miami Beach (CITY) receives potable water from the Miami -Dade Water and Sewer Department (MDWASD) by means
of four transmission mains. One of these transmission mains is located along the Venetian Causeway. Water is conveyed into the
Venetian Islands from MDWASD through one 30-inch ductile iron pipe (DIP) water main that splits into two parallel 16-inch water
mains at each bridge crossing. These parallel mains travel aerially along the Venetian bridges on the north and south face of each
bridge, with the exception of the recently installed subaqueous segment between Rivo Alto Island and Belle Isle.
Similarly, sewage is transmitted from the Venetian Islands due east through a series of sewer main aerial crossings on the Venetian
Causeway historic bridges. Each bridge carries a DIP force main that ranges in size from 8 to 12 inches. The crossings between
Rivo Alto Island and Belle Isle, and between Belle Isle and Dade Boulevard on the main island, were recently replaced sub-
aqueously through emergency projects.
The overall condition of the remaining water and sewer main aerial crossings along Venetian Causeway is poor. The replacement of
these aerial water and sewer mains crossings were prioritized in the City Water and Sewer Master Plans due to high probability and
consequence of failures. Mechanically, all the aerial TR Flex bell and spigot pipe (inspected under a previous service order) have a
failed coating system or are uncoated, resulting in significant corrosion. Air release valves (ARV) show extensive corrosion from
exposure to the saltwater. Furthermore, in multiple locations failed water main supports have caused pipe deflections that appear to
exceed manufacturer recommendations for the TR Flex joints. From a structural standpoint, in general pipe hangers show signs of
significant corrosion. Some pipe supports are failing and/or missing at most of the bridges along Venetian Causeway. Several pipe
failures have caused significant impact to our residents and to the environment.
The City retained Hazen and Sawyer, PC, Prime Water and Sewer Consultant, to design the replacement of the pipes as
recommended in the Master Plan,, per Resolution No. 2020-31211. The design effort is now completed and is currently in permitting.
The scope of work includes the following:
• Four horizontal directional drill segments to replace water main bridge -aerial crossings between San Marco, San Marino, Di Lido
and Rivo Alto Island and between Belle Isle and Dade Blvd in Miami Beach.
• Two horizontal directional drill segments to replace sanitary force main bridge -aerial crossings between San Marino, DiLido and
Rivo Alto Islands.
The water main replacement segments include about 5,000 linear feet (LF) of HDPE Pipe installed via horizontal directional drill
(HDD) and about 450 LF of Ductile Iron Pipe (DIP) via open cut. The force main replacement segments include about 2,500 LF of
HDPE pipe installed via horizontal directional drill and about 130 LF of DIP via open cut. The design has been closely coordinated
with the Miami -Dade County Department of Transportation and Public Works (DTPW)'s design for demolition and construction of 11
bridges along the Venetian Causeway (MD Public Project No. 20210011). These bridges were originally constructed in 1920's and
have exceeded their useful life. The replacement of the water and sewer pipes with new aerial crossings on the bridges is no longer a
feasible option.

FINANCIAL INFORMATION
There will be no fiscal impact as this is a request to waive the independent cost estimate requirements and authorize the competitive
bidding of the Venetian Causeway Water Mains and Force Mains Replacement (Phase 2) Project. The projects construction cost
was estimated in October 2023 by the engineer of record at $20 million (Class 2 estimate with +20% to -15% accuracy, thus in the
range of $17 million to $24 million). This project is fully funded as part of Capital Project No. 28520 Water and Wastewater Mains and
Rehab.
CONCLUSION
This pipeline replacement project is anticipated to have a construction duration of approximately 18 months, and it is required to be
completed prior to July 2025, when the Miami -Dade County Department of Transportation and Public Works (DTPW) plans to initiate
the construction of the Venetian Causeway Bridge Replacement Project.
In an effort to fast -track the implementation of this critical pipeline replacement project and meet the County's project schedule
requirements, the Administration recommends waiving the City s requirement for projects exceeding $5 Million in construction cost, to
complete an independent cost estimate ahead of issuing for bid (Resolution 2022-32047). Therefore, the Administration
recommends proceeding with the competitive bid of the Venetian Causeway Water and Sanitary Sewer Mains Replacement (PHASE
2).
