INTRODUCTION
The attached resolution provides for the acceptance of the public improvement
construction contract for the Mystique Ice Center - Rink Ice System Removal and
Replacement Project.
BACKGROUND
The mitigation work for the ice arena settlement remediation has been successfully
completed. The first phase of work began on June 1 st with the removal of the original
existing rink dasher boards and shielding, the rink ice system, and bleachers to allow for
the installation of a non-destructive deep foundation system under the rink area and
throughout the lower-level main floor interior finished building space. Once the settlement
and foundation system were completed, a concrete subfloor was installed and supported
on the deep foundation system. Once the concrete subfloor was in-place, a new
refrigerated ice rink concrete floor was installed which is now supported by the subfloor
slab and foundation. Once the refrigerated ice rink floor was operational, the arena
bleachers and seating were reinstalled along with installation of new dasher boards, and
the installation of new rubber sport flooring on the lower-level main floor. All this work was
successfully completed, and the Dubuque Ice Arena was reopened to the public on
November 2, 2022.
The Mystique Ice Center - Rink Ice System Removal and Replacement Project provided
for the complete removal of the original rink and ice system to allow for the installation of
a deep foundation system under the rink area. Once the settlement and foundation
system was completed (by others) and a reinforced concrete subfloor was constructed
(by others), a new rink ice system was installed. The new rink ice system included the
installation of a subfloor heating system, the installation of new coolant piping, and the
installation of a new refrigerated concrete rink floor. The rink ice system projects also
included restarting the ice plant cooling system and the installation of the ice sheet
surface.
DISCUSSION
The Mystique Ice Center - Rink Ice System Removal and Replacement Project was
completed by Rink-Tec International, Inc. of Vodnais Heights, MN in the final contract
amount of $816,201.42. This is a 13.2% increase from the original contract amount of
$720,950.00.
The increase ($95,251.42) was due to additional costs incurred during the restart of the
arena ice plant cooling system. When shutting down the ice plant system and leaving
the system site idle for 6 months while the settlement remediation work was completed,
upon Rink-Tec starting the ice system back up, mechanical issues were discovered with
the compressors. Unfortunately, due to the age of the original compressors and the
operating hours, over 50,000 hours per compressor, the startup process from an
extended idle period was demanding and stressful on the compressors and
components. As a result, of the four (4) ice system compressors, B2 was operating at
approx. 50% and A2 stopped operating on Mar 3�a
Through approved contract change orders, Rink-Tec was authorized to replace all
bearing couplers, shaft seals, procure and install two (2) new ice system compressors,
and install new compressed liquid refrigerant for the ice plant cooling system.
RECOMMENDATION
I recommend that the City Council accept the improvements and authorize the payment
of the final contract amount of $816,201.42 to Rink-Tec International, Inc. for the
Mystique Ice Center - Rink Ice System Removal and Replacement Project.
