DATE: November 8, 2020
Water Department Manager Denise Blakeley Ihrig is recommending acceptance of the
construction contract for the Roosevelt Street Water Tower Contract B Eagle Point
Plant & Water Distribution Improvements Project, as completed by Portzen
Construction, Inc., in the final contract amount of $1,058,389.67, which is 7.27% over
the bid amount. This is mainly due to an increase in material prices. There is
$26,892.33 remaining in the project contingency. It is further recommended that the
City Council authorize the final payments including retainage, minus $6,000 for Contract
B in the amount of$117,253.00 to Portzen Construction. There will be a final payment
of $6,000 following successful start-up of the pressure reducing control valves, which
cannot be verified or set until the Roosevelt Street Water Tower is on-line.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

RE: Roosevelt Street Water Tower
Contract B Eagle Point Water Plant & Water Distribution Improvements
Project Acceptance and Release of Retainage
INTRODUCTION
The enclosed resolution provides for the acceptance of the construction contract, final
payment adjusted for Change Order No. 4, and release of retainage, with the exception of
$6,000 withheld for final start-ups, for the Roosevelt Street Water Tower Contract B Eagle
Point Plant & Water Distribution Improvements.
BACKGROUND
In June 2018, with support from the City Manager and Council, the City's consulting engineer,
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
On November 5, 2020, the City received communication from its project design engineer, IIW,
P.C. recommending approval and acceptance of Contract B, Eagle Point Water Plant & Water
Distribution Improvements, and requested approval of final payment including retainage. IIW,
P.C. documents early retainage release was requested by the contractor, as is permissible
under lowa Code.
There is one exception to the full release of retainage, which is associated with the final start-
up of the control valves in the pressure reducing stations. This final step is beyond the control
of the contractor as pressure reducing valves cannot be verified or set until the Roosevelt
Street Water Tower is on-line. Therefore, as requested by the project engineer and
contractor, there will be a final payment of $6,000 made following successful start-up of the
pressure reducing control valves.
The contractor and engineer have also presented a final change order, Change Order No. 4,
reconciling all contract line items. The change order reduces the overall contract amount and
is a credit of$11,923.46.
BUDGET IMPACT
Contract B, Eagle Point Plant & Water Distribution Improvements, is funded through the State
