ISSUE BEFORE COUNCIL: Should the City Council approve Change Order No. 2 for the 2020 Mill
and Overlay project?
BACKGROUND: Minnesota Paving and Materials was awarded a construction contract on June 2, 2020
to complete the 2020 Mill and Overlay Project. The work is substantially completed with the exception of
minor punch list items. The project had a substantial completion date of August 28, 2020 and final
completion date of September 18, 2020.
PROPOSAL DETAILS/ANALYSIS: Minnesota Paving and Materials has submitted a change order to
address additional work required to complete various aspects of the project as follows:
• The project bid included a line item to adjust existing valve boxes to the final pavement height. During
construction, it was discovered that three valve boxes could not be adjusted as their existing valve boxes
were broken or damaged before the project began. Additional work and materials were required by the
contractor to replace the broken valve box sections.
• Additional work and materials were required by the contractor to replace a section of roadway where
the underlaying base material failed. The aggregate base section was removed and replaced with new
material and the area was repaved.
• Additional shoulder grading work was required by the contractor to grade the shoulder for positive
drainage. Following the paving of the wear course pavement, areas of the shoulder were higher than
the drive lane, prohibiting runoff from leaving the roadway.
FISCAL IMPACT: This change order will increase the contract in the amount of $10,542.00 bringing the
revised construction contract to $343,602.18. With this change order the project remains within the planned
budget.
RECOMMENDATION: Staff is recommending that the City Council approve, as part of the Consent
Agenda, Change Order No. 2 for the 2020 Mill and Overlay Project. If removed from the consent agenda,
the recommended motion for the action is as follows:
“Move to approve Change Order No. 2 for the Mill and Overlay Project, thereby increasing the
contract amount by $10,542.00”.
