WHO REQUESTED THE CHANGE U City ❑ Contractor
WHY IS THE CHANGE NECESSARY
Check all that apply
❑ Unforeseen / Hidden Conditions ❑ Scope Change
I] Error with the Plans and/or Specifications El Other - describe below
Explanation:
Design flaw prohibits accurate effluent flow measurement required by the NPDES permit.
REASON FOR CHANGE ORDER VS. BIDDING ADDITIONAL WORK
Check all that apply
❑ The work is in the area of the original contract and a conflict with the on-site contractor is probable and
would make coordination of work difficult and bidding unreasonable.
❑ Time is of the essence and bidding would require the contractor to stop work and the City would face
costly standby fees therefore making bidding disadvantageous
❑ Emergency Work to correct unsafe conditions.
i] Other - describe below
Explanation: (attached additional pages if needed)
This work is a direct result of a design error. It would be unreasonable to inlist the services of a different design firm at this stage of
the project.

The new change order is to include compensation by CH2M to the City (CH2M to pay City of

of the costs associated with outside services provided by Materials Testing & Inspection (MTI)

which include concrete testing, epoxy embed verification, rebar verification, and subgrade
compaction testing.

II. DESCRIPTION
A. Background
The UV disinfection system expansion project at the Wastewater Resource
Recovery Facility is almost complete. During the expansion it was determined
that a critical design error was made on the elevation of the Parshall flume that
caused inaccurate effluent flow measurement. A temporary fix was put in place
while a plan was devised to correct the error. The redesign is finished and ready
to be implemented to complete the project.
B. Proposed Project
To allow for accurate measurement of the effluent flow and to stay in compliance
with the City's NPDES permit, the following changes are critical:
• The UV disinfection system flume will be expanded and a new flume
insert installed.
• The pipe upstream of the flume will be re-layed at a lower slope
percentage.
Page I of 2
C. Describe Item
This deductive change order will cover the construction costs of the additional
flume and pipe. CH2M, the original design engineering company, is providing all
engineering support services related to this portion of the project at no cost to the
City.
