AGENDA ITEM: I-94 Lift Station (No. 1) and Sanitary Sewer Improvements - Change Order No. 3
SUBMITTED BY: Jack Griffin, City Engineer
REVIEWED BY: Kristina Handt, City Administrator
Rob Weldon, Public Works Director
Chad Isakson, Project Engineer
ISSUE BEFORE COUNCIL: Should the City Council approve Change Order No. 3 for the I-94 Lift
Station (No. 1) and Sanitary Sewer Improvements?
BACKGROUND: RL Larson Excavating, Inc. was awarded a construction contract to complete the I-94
Lift Station (No. 1) and Sanitary Sewer Improvements on May 2, 2017. Construction remains in progress
with some site work and restoration remaining.
PROPOSAL DETAILS/ANALYSIS: RL Larson Excavating, Inc. has submitted a change order to revise
the substantial completion date from November 17, 2017 to July 27, 2018 and revises the final completion
date from December 15, 2017 to August 17, 2018. The extended construction contract completion period
was needed to allow for the delay in ordering and delivery of the revised lift station pumps previously
approved by the City as Change Order No. 1 and weather conditions turning in early November 2017
preventing further roadway improvements being constructed.
Also, a change order is needed to address additional work items requested by the City to be completed by
the contractor, including sanitary sewer manhole extensions and additional pavement surface to enhance
access and maintenance at the lift station site. This change order also addresses quantity overruns mainly
associated with rebuilding the shoulder and turn lane on Hudson Boulevard. Poor soils were discovered
during the construction causing an overrun of roadway materials.
FISCAL IMPACT: None. This change order increases the contract amount by $62,338.80 for a total
contract amount of $889,332.22. With this change the project remains below the feasibility project budget
but is $29,500 over the project amount that the City bonded for.
RECOMMENDATION: Staff is recommending that the City Council approve, as part of the Consent
Agenda, Change Order No. 3 for the I-94 Lift Station (No. 1) and Sanitary Sewer Improvements. If removed
from the consent agenda, the recommended motion for the action is as follows:
“Move to approve Change Order No. 3 for the I-94 Lift Station (No. 1) and Sanitary Sewer
Improvements, thereby revising the substantial completion date from November 17, 2017 to July 27,
2018; revising the final completion date from December 15, 2017 to August 17, 2018; and increasing
the contract amount by $62,338.80”.

CHANGE ORDER DESCRIPTION / JUSTIFICATION:
This Change Order revises the substantial completion date from November 17, 2017 to July 27, 2018 and revises the final
completion date from December 15, 2017 to August 17, 2018. The extended construction contract completion period was
needed to allow for the delay in ordering and delivery of the revised lift station pumps previously approved by the City as
Change Order No. 1 and weather conditions turning in early November 2017 preventing further roadway improvements being
constructed.
The City is requesting the contractor to complete additional work on the I‐94 Lift Station Improvement project. Additional
pavement at the lift station site has been requested by Public Works for access, maintenance, and operation purposes. In
addition, two sanitary sewer manholes need to be raised to match the field graded ditch section and to meet City standards.
This change order also addresses quantity overruns mainly associated with rebuilding the shoulder and turn lane on Hudson
Boulevard. Poor soils were discovered during the construction causing an overrun of roadway materials.
