DATE: May 13, 2026
City Engineer Gus Psihoyos is recommending City Council award the Public
Improvement Construction Contract for the Loras Blvd. & Locust St. Storm Sewer
Reconstruction Project to Gansen Excavating, Inc. in the amount of$512,919.92 for
both the Base Bid and Alternate No. 1, which is 8.0% below the revised estimate of
probably cost, through adoption of the attached resolution.
The construction estimate of probable cost has increased by $78,400 since the project
Public Hearing memo, reflecting final plan cost adjustments, prebid addendum, and
incorporating the Alternate Bid No. 1 estimated cost.
This project involves replacing approximately 375 feet of failing storm sewer beneath
Loras Blvd. and reconstructing the full width of pavement from the intersection of Loras
Blvd. and Locust St. eastward to Main Street. The project will also reconstruct all
pedestrian ramps within the limits to meet current ADA standards.
As part of the project, the bid documents included Alternate Bid No. 1 for the removal
and replacement of the concrete pavement on Loras Boulevard between Bluff Street
and Locust Street. In advance of this summer's construction, the Loras and Bluff
intersection was recently reconstructed to ensure it can remain open and accommodate
the designated traffic detour route during the project. Staff believe it is the appropriate
time to replace this one-block segment of older concrete pavement (Bluff to Locust).
I concur with the recommendation and respectfully request Mayor and City Council
approval.

SUBJECT: Loras Boulevard & Locust Street Storm Sewer Reconstruction Project
Award Public Improvement Contract
Project No. 5586500042
DATE: May 12, 2026
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 Loras Blvd. & Locust St. Storm Sewer Reconstruction Project.
BACKGROUND
The need for this work became more urgent following a roadway undermine in
November 2021, when a storm sewer failure temporarily closed Loras Blvd. Subsequent
evaluations showed that the storm system in this area is generally in poor condition and
has exceeded its expected service life, contributing to ongoing settlement and
undermine concerns.
DISCUSSION
This project involves replacing approximately 375 feet of failing storm sewer beneath
Loras Blvd. and reconstructing the full width of pavement from the intersection of Loras
Blvd. and Locust St. eastward to Main Street. The project will also reconstruct all
pedestrian ramps within the limits to meet current ADA standards.
BID RESULTS
The City received sealed bids on May 7, 2026, for the Loras Blvd. & Locust St. Storm
Sewer Reconstruction Project. Gansen Excavating, Inc., of Dubuque, IA submitted the
low base bid in the amount of $453,488.57, which is 8.0% below the revised estimate of
probable cost. A summary of the bid proposals received is as follows:

ALTERNATE BID NO. 1
As part of the project, the bid documents included Alternate Bid No. 1 for the removal
and replacement of the concrete pavement on Loras Boulevard between Bluff Street
and Locust Street. In advance of this summer's construction, the Loras and Bluff
intersection was recently reconstructed to ensure it can remain open and accommodate
the designated traffic detour route during the project. Staff believe it is the appropriate
time to replace this one-block segment of older concrete pavement (Bluff to Locust).

Storm Sewer Reconstruction Project be awarded to Gansen Excavating, Inc. for both
