LEGISLATIVE HISTORY/BACKGROUND INFORMATION: A change in field conditions was discovered during construction of the lift station site. The elevation of an existing 4-inch gravity sewer service pipe connecting the Elmo View Townhomes to the city-owned drainfield was found to be approximately 3.5 feet below existing
grade. In addition, the proposed grading plans indicated further lowering the grade over this pipe
in order to construct the access driveway to the lift station from Lisbon Avenue. Lowering the existing grade over the sewer pipe would increase the likelihood of freezing and/or damaging the pipe and causing operational issues with the wastewater treatment system. The existing system is to remain in place for the Elmo View Townhomes until the new lift station receives significant
wastewater flow in the future.
The Contractor has completed the work at the unit price of $8.66 per cubic yard to import select granular material and grade the site to maintain the existing cover over the 4-inch sewer service pipe. This results in an increase of $6,053.34, which equates to a revised Contract Amount of
$3,458,721.24.
RECOMMENDATION: Staff is recommending that the City Council consider approving, as part of the Consent Agenda, Change Order No. 4 for the Lake Elmo Avenue Sewer Infrastructure Improvements: I-94 to 30th
Street, thereby increasing the Contract Amount by $6,053.34. If removed from the consent agenda, the recommended motion for this action is as follows:
“Move to approve Change Order No. 4 for the Lake Elmo Avenue Sewer Infrastructure Improvements: I-94 to 30th Street in the amount of $6,053.34.”
