From: Nick Egger – Public Works Director

Item: Approve Change Order #1 for Riverfront Renaissance Phase 3.1 Improvements
COUNCIL ACTION REQUESTED
Council is requested to approve the attached change order to the contract for Phase 3.1 of the Riverfront
Renaissance program.
BACKGROUND INFORMATION
The Change Order covers an adjustment to the size of an underground “trough” wherein mainline electrical feed
lines have to reach between a transformer and the service connections. The size adjustment is necessary in light
of updated information about the electrical feed necessary to serve the Meyer Company Building that was not
known at the time of bidding the project. Also covered in this change order is the addition of an underground
hand hole for wiring junctions, and a change to the door assembly on the eastern dumpster enclosure to provide
four moderately sized doors instead of two, for more ease of operability by users of that enclosure.
Sam Kessel of Bolton & Menk has provided elaboration on the various adjustments and added work items in the
attached memo to help explain the background.
FINANCIAL IMPACT
The value of the items contemplated by Change Order #1 is a $7,736.46 increase to the total contract value, about
a 1.52% increase.
