RE: Roosevelt Street Water Tower
Contract A Roosevelt Street Water Tower and Water Distribution Improvements
Project Acceptance and Release of Retainage
INTRODUCTION
The enclosed resolution provides for the acceptance of the construction contract and
requests release of retainage, adjusted for Change Order No. 4, for Contract A Roosevelt
Street Water Tower and Water Distribution Improvements.
BACKGROUND
In June 2018, with support from the City Manager and Council, the City's consulting engineer,
Origin Design, formerly IIW, P.C. of Dubuque, lowa, completed planning and design of the
Roosevelt Street Water Tower Project, which included a 1.25-million-gallon elevated water
storage tower, pressure reducing stations, water main improvements, and water treatment
plant pump improvements.
The Roosevelt Street Water Tower project is the result of extensive analysis to determine the
best solution to increase operating pressures in one of the City's nine pressure zones,
Pressure Zone 2. Several studies identified the need for increased pressures in the area as
the existing elevated water tower located in Eagle Point Park was determined to be limiting
the available water pressure in the zone. Most notably the pressure at the highest point along
Roosevelt Street, which has been recorded in the range of 20 and 25psi. This is problematic
when looking to achieve typical recommended system pressures of 60 to 80 psi with a
minimum working pressure of 35psi to serve current, new, and future developments.
In April 2019, the City of Dubuque awarded two contracts to complete the work, Contract A
which included the construction of the Roosevelt Street 1.25 MG Elevated Water Tower to
McDermott International (dba CB&I) in the amount of$2,928,600; and Contract B, the Eagle
Point Water Plant and Water Distribution Improvements to Portzen Construction of Dubuque,
lowa in the amount of$986,620.
DISCUSSION
The water tower was substantially complete and operational for the City of Dubuque's use on
December 18, 2020.
On June 22, 2022, the City received communication from its project design engineer, Origin
Design, recommending approval and acceptance of Contract A, Roosevelt Street Water
Tower and Water Distribution Improvements. Origin Design and CB&I,LLC. is requesting
approval of Change Order No. 4 reconciling all contract line items in a credit amount of
$15,585.40.
The final payment and retainage requested is in the amount of$145,943.19.
BUDGET IMPACT
Contract A, Roosevelt Street Water Tower and Water Distribution Improvements, is funded
through the State of lowa, Revolving Loan Fund. The following table details the approved
Contract A expenses and contract adjustments:
