Change Order No. 6 Backup Sheet
Description of Need & Cost Evaluation
Prepared by: Don Tulloch, P.E. — Gray & Osborne, Inc.
Date: July 21, 2016
COP 029 — 120 V Power to LCP-251
Background Information: Per Change Order Proposal 12, the location of LCP-251 was switched
with the location of LCP-250 so that the control panel with the VFD would be protected inside
the sludge pump room. LCP-251 was installed by the wet well where LCP-250 was originally
planned. However, the original plans did not include power to the control panel located by the
wet well. Therefore, additional conduit must be provided to provide 120 V power from the
adjacent light pole to LCP-251.
Cost Evaluation: The change order pricing is $1,906.10. These costs appear reasonable. If the
power connection had been added as a part of Change Order Proposal 12, the cost likely would
have been higher because more conduit would have been needed to provide power from the
sludge pumping room.
The final additive price for this change item is..........................................................$1,906.10
Increase contract time (calendar days)..........................................................................1 days

This memo has been provided as supporting documentation for change order number 5 for the primary
clarifier project. This change order is for a total of $2,070.02, including tax, and includes the following
items:
1. 120 Volt Power to LCP-251—$2,070.02
This change order includes the cost of additional conduit that was needed to
power LCP-250. This additional conduit is needed because the location of
LCP-251 was switched with the location of LCP-250 so that the control panel
with the VFD would be protected inside the sludge pump room; rather than
next to the primary clarifier where it was originally planned to be installed.
It's believed that the gases from the clarifier would shorten the expected life of
the VFD. The original plans did not include power to the control panel located
by the wet well.
Steve Brewer and Dan Ford approved the change order on July 27, 2016.
Please sign the attached change order. If you have any questions or any additional information is
needed, please let me know.
Thank you,
