ISSUE BEFORE COUNCIL: Should the City Council approve Change Order No. 4 for the Old Village
Phase 3 Street, Drainage, and Utility Improvements?
BACKGROUND: Douglas-Kerr Underground, LLC was awarded a construction contract to complete the
Old Village Phase 3 Street, Drainage, and Utility Improvements on May 16, 2017.
PROPOSAL DETAILS/ANALYSIS: Douglas-Kerr Underground, LLC has submitted a change order to
address additional work completed for the following items:
1. Revise storm sewer pipe size on 31st Street. Increased pipe capacity is required as part of the
stormwater treatment basin elimination, per the Valley Branch Watershed District permit.
2. Remove and dispose of a concrete pillar monument from 3200 Lake Elmo Avenue as ordered by
Washington County for work related to the Old Village Phase 2 project. Washington County will
reimburse Lake Elmo for the work through a credit on the Phase 2 project invoice.
3. Raise a City owned sanitary sewer manhole on Lake Elmo Elementary School property by adding
a barrel section to match the elevation with the final grading in the playground area.
FISCAL IMPACT: This change order will increase the contract in the amount of $5,386.40 bringing the
revised construction contract to $1,583,940.42. With this change order the project remains within the
authorized project budget and contingencies.
RECOMMENDATION: Staff is recommending that the City Council approve, as part of the Consent
Agenda, Change Order No. 4 for the Old Village Phase 3 Street, Drainage, and Utility Improvements. If
removed from the consent agenda, the recommended motion for the action is as follows:
“Move to approve Change Order No. 4 for the Old Village Phase 3 Street, Drainage, and Utility
Improvements, thereby increasing the contract amount by $5,386.40”.
