EXECUTIVE SUMMARY
City Council Meeting: November 5, 2018
AGENDA ITEM: Change Order 2 and 3 for Well House 16,
City Project 416
AGENDA SECTION:
Consent
PREPARED BY: Brian Erickson, PE, Director of Public
Works/City Engineer AGENDA NO. 6.j.
ATTACHMENTS: Water Main Extension Proposal; Gate
Valve Replacement Proposal APPROVED BY: LJM
RECOMMENDED ACTION: Motion to approve a Change Orders 2 and 3 for additional
work required to complete the work required on Well House 16, City Project 416
BACKGROUND
On October 3, 2017, City Council awarded the construction contract for Well House #16 to Rice Lake
Construction Group (RLCG). On May 1, 2018, Council approved Change Order 1 to the contract. At this
time RLCG has nearly completed their work on this project and there are two remaining changes that have
been negotiated for this project.
Change Order 2 covers three additional elements of work not covered under the contract. While
performing excavation as part of their work, RLCG discovered a large concrete block that required
removal in order to install the necessary underground piping. That work required significantly more effort
than standard excavation resulting in added cost. Also, as part of the utility system Well 16 is required to
be connected to the SCADA network. Unfortunately, the planned fiber routing needed to be adjusted
which required a change to the length as well as the need to add tracer wire to the route to insure it can be
located in the future. Total cost for Change Order 2 is $27,724.00.
Change Order 3 cover the following additional work items. Additional electrical work was required to
locate the transformer as required by Dakota Electric resulting in additional wiring and conduit that was
not shown in the original design. Due to the difficulty of maintaining a turf area near the retaining wall,
staff requested that the area be filled with concrete resulting in additional cost. Finally, contractor testing
of the well pump and associated components resulted in significant power usage which was charged to the
city by Dakota Electric. As a result, the city is receiving a deductive change to cover this cost. Total cost
for Change Order 3 is $10,830.35.
RECOMMENDATION
Staff recommends Council approval of the attached change orders in order to complete the construction
of Well House 16, City Project 416.

Dear Steve
Killmer Electric Company proposes to the following change to our contract for the
subject project:
– Change Request for Revised Transformer location
Meeting was had on site to select a transformer location as there was such a large
gradient the location shown on plan sheet E-02 would not work. Also the serving Utility
company Dakota Electric required it 25ft from any door or window. This placed the
transformer 60ft further from plan location for the associated feeder. Also Dakota
Electric Associated required (2) 4” PVC from near their switch location to the
transformer pad. This is an additional requirement than what Xcel energy would have
required per noted serving utility in sheet E-02.
