DATE: November 25, 2024
City Engineer Gus Psihoyos is recommending City Council award the Public
Improvement Construction Contract for the Kerper Boulevard Lift Station Project to
Tschiggfrie Excavating Co. in the amount of$1,843,385.90, which is 13.06% over the
engineers estimate.
In October of 2023, the City Council approved the disposal of 5.25 acres of City
property located at the corner of Kerper Boulevard and Hawthorne Street to Union at
the Marina, LP and approved a development agreement with same. Per the agreement,
Union at the Marina, LP will construct buildings with 201 residential units at an
aggregate cost of approximately $45.7 million. And that they will use reasonable efforts
to start construction of the improvements within six (6) months of the closing date.
The existing sanitary sewer lift station located on Kerper Boulevard near the property to
be developed by Union at the Marina, LP was constructed in 1957. While the pumps
were replaced in 2005, the facility has reached the end of its design life as reflected by
the increased maintenance costs. The existing lift station cannot be upgraded to
accommodate the additional flows from the proposed development, or to accommodate
existing and future flows within the service area limits, within the constraints of the
existing structure. The project will be funded with an appropriation in the amount of
$1,498,266 for the design and construction of the Kerper Boulevard Lift Station Project,
with revenue from an American Rescue Plan Act (ARPA) grant from an allocation made
during FY24 Budget Amendment #2. An additional $300,000 of ARPA funding has been
requested to be reallocated to this project as part of FY25 Budget Amendment #1, for a
new project total funding of$1,798,266. Due to the uncertainty of recent construction
market bid prices, specifically with lift stations involving items with long supply chain
lead times, City staff has included a request for an additional $500,000 in funding as
part of the FY26 CIP requests.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

SUBJECT: Kerper Boulevard Lift Station Project
Award Public Improvement Contract
Project No. 5581500047
INTRODUCTION
The purpose of this memorandum is to provide the City Council with information related
to the recommendation for awarding the Public Improvement Construction Contract for
the Kerper Boulevard Lift Station Project.
BACKGROUND
In October of 2023, the City Council approved the disposal of 5.25 acres of City
property located at the corner of Kerper Boulevard and Hawthorne Street to Union at
the Marina, LP and approved a development agreement with same. Per the agreement,
Union at the Marina, LP will construct buildings with 201 residential units at an
aggregate cost of approximately $45.7 million. And that they will use reasonable efforts
to start construction of the improvements within six (6) months of the closing date.
The existing sanitary sewer lift station located on Kerper Boulevard near the property to
be developed by Union at the Marina, LP was constructed in 1957. While the pumps
were replaced in 2005, the facility has reached the end of its design life as reflected by
the increased maintenance costs. The existing lift station cannot be upgraded to
accommodate the additional flows from the proposed development, or to accommodate
existing and future flows within the service area limits, within the constraints of the
existing structure. Therefore, a new lift station is proposed near the existing facility.
When complete, the existing lift station would be decommissioned.
DISCUSSION
On January 17, 2024, the City advertised a Request for Proposals (RFP) to retain a
professional service consultant to aid the City in evaluating the existing collection and
pumping systems that transport sanitary sewage in the Kerper Boulevard Lift Station
sewer service area, develop a facility plan with phased improvements to address
identified high risk infrastructure within the sewer service area, and to design and
construct the lift station replacement. On March 19, 2024, the City entered into a
contract with Origin Design, the selected consultant, for the engineering services to
design the replacement of the Kerper Boulevard Lift Station. The project design is
Page 627 of 645
complete, has received the lowa Department of Natural Resources (IDNR) wastewater
construction permits, and is ready for advertisement for construction.
