CHANGE ORDER NO. 6
SCOPE. This Change Order No. 6 covers the following change to the
Contract Documents:
Add lump sum for modification of effluent pumps EP-804 and 805
to increase the performance capacity of the pumps.
REASONS FOR CHANGE:
A lump sum add is included for modification of effluent pumps
EP-804 and 805, along with associated motors and variable speed
drives, to increase the performance capacity of the pumping units.
The performance capacities of EP-804 and 805 require modification
to allow pumping of effluent water to Southwestern Public Service
(SPS) at a higher flow rate than anticipated at the time of design.
In addition to the higher flow rates, the length of discharge
piping to SPS was considerably longer than information at the time
of design indicated. The increased flow rate and longer discharge
pipeline necessitates the increase in performance characteristics of
the pumping units. SPS has a contract with the City which pays the
City for the effluent water that SPS receives. The increased flow
rate required by SPS will result in a substantial increase in
revenues received from SPS.
Attached to this Change Order is a copy of Black & Veatch letters
CP-15 and CP-15A, along with a cost breakdown from BRB Contractor-s
Inc. for the work performed.
BASIS FOR CHANGE:
Modify effluent pumps EP-804 and 805, including motors and variable
speed drives, to increase performance characteristics of the pumps
for a lump sum cost of $84,599.68.

Resident Project Representative, Mr. Steve Keeling, for copies of the
existing shop drawings or other related information. Please proceed with
the following work.
• Remove the 50 horsepower motors and replace with 75 horsepower motors
bf identical construction. If acceptable to the manufacturer, return
the motors for a credit.
• Remove the pumps and install one additional pump bowl assembly on
each pump. The pump column and shaft shall be shortened as required
to maintain the original overall length of the unit. Please contact
Mr. Chester Hopper of C&H Pumps (817) 268-4995. He is aware of the
scope of work for this item.
• Change the breakers for each pump from 3P-100 amp to 3P-150 amp. The

• Refer to sheet E-18 of the drawings for Contract 2, circuit ME-6 for
EP-804 and circuit ME-7 for EP-805. Please perform the following
wiring and conduit changes for each pump:
From the motor control center to the adjustable frequency
drive, route a circuit with 3#1/0, 1#6G, in a new 1-1/2 inch
conduit. The conduit may be routed overhead. Disconnect the
existing circuit and remove the wiring.
From the adjustable frequency drive to the motor, remove the
existing wiring and install new wiring (3#1/0, 3-4/C#14, 4#12,
#6G) inside the existing 2-inch conduit.
We are currently reviewing possible modifications or replacement of the two
adjustable frequency drives. Once we complete our review of this item, we
will notify you of the scope of that portion of the work. If you have any
comments or questions, please feel free to call me.
