INTRODUCTION
Dubuque
AII•Amarica City
2007-2012.2013
2017*2019
The attached resolution provides for the acceptance of the public improvement
construction contract for the Mystique Ice Center - Stadium Seating Removal &
Replacement Project.
BACKGROUND
City staff evaluated foundation soil remediation alternatives and consulted with several
design -build geotechnical contractors that specialize in low mobility, low head room
clearance, interior finished building, non-destructive deep foundation stabilization
applications. The settlement remediation solution that was implemented utilized the
installation of deep compaction grout columns to density the subgrade soils below the
concrete floor slab. The grout columns were installed on an approximate 10-ft. by 10-ft.
grid throughout the arena lower main level to a depth of treatment of approximately 30 to
35 feet. Once the deep compaction grout columns were installed to support the main level
floor slab, rink, bleachers, and interior block walls, a 2-part expanding polyurethane foam
was injected beneath the slab to fill voids, while providing the final lifting, re -leveling, and
stabilizing the floor slab.
The mitigation work for the ice arena settlement remediation has been successfully
completed. The first phase of work began on June 1st with the removal of the rink dasher
boards, 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 1, 2022.
The Mystique Ice Center - Stadium Seating Removal & Replacement Project provided
for the disassembly and removal of the 1st, 2nd, and 3rd rows of the arena stadium
bleacher seating. The stadium bleacher aluminum treads, risers, half steps, and chairs
were disassembled and stored on the concourse level. Upon completion of the
Settlement Remediation Project and the construction of a new Ice Rink Refrigerated
Concrete Floor, performed by others, the arena stadium bleacher seating was
reassembled and reinstalled.
DISCUSSION
The Mystique Ice Center - Stadium Seating Removal & Replacement Project was
completed by Portzen Construction, Inc. of Dubuque, IA in the final contract amount of
$85,750.00. This is an 2.4% increase over the original contract amount of $83,764.00.
The increase in cost was due to additional efforts needed to install and adjust new
bleacher aluminum interlock deck treads.
RECOMMENDATION
I recommend that the City Council accept the improvements and authorize the payment
of the final contract amount of $85,750.00 to Portzen Construction, Inc for the Mystique
Ice Center - Stadium Seating Removal & Replacement Project.
