TO BE CONSTRUCTED AND THAT IS AN INTEGRAL PART OF THE PROJECT OBJECTIVE. After performance of a
construction contract begins, Change Orders may be approved if necessary to 1) make changes in plans or specifications; or 2)

This Change Order includes adding power to existing light poles and the west gate operator, the removal of snails from the
existing aeration basins, the replacement of inoperable dampers at the Headworks, the replacement of mud valves and
pressure relief valves in the existing aeration basins and in existing primary and secondary clarifiers, the relocation of existing
drain valve for Secondary Clarifier 1, the reroute of the existing storm drain at the Plant 4 filters, the reroute of the Plant 3
filter backwash line, the addition of a platform at the analyzers at BNR 3, the deletion of the construction joints at the Plant 4
filter slab, and the deletion of the shoring system on the west side of the Plant 4 filters by using a portion of the chlorine
contact basin wall. The total cost of this change order is $99,058.70. The contract will be extended by eight calendar days.

Subject: Change Order 11
Attached with this letter is documentation for Change Order No. 11. This change order involves the
following items.
1. During Plant 4 construction activities, it was determined that power to two existing light poles and the
existing west gate operator was lost when the Intermediate Lift Station was demolished. In order to
restore the power, conduit will be added from the new BNR electrical building to power the existing
facilities. Eagle provided a cost proposal of $4,481.49 to complete the work.
The following documents are attached to support this change.
• RFI -102 with response from Black & Veatch dated December 1, 2009.
• Letter dated March 30, 2010 from Glenn Grant (PCM -60) with the cost breakdown.
• Letter dated April 5, 2010 from Glenn Grant (PCM -60R) with the revised cost breakdown.
• Letter dated June 8, 2010 from Glenn Grant (PCM -60R) with the revised cost breakdown.
2. When the two existing aeration basins were drained so that they could be rehabilitated for the new
BNR process, it was discovered that there was an accumulation of snail shells that could not be
drained through the drain system and needed to be removed by mechanical means. Eagle provided a
cost proposal of $8,536.52 to complete the work.
The following documents are attached to support this change.
• Letter dated March 26, 2010 from Laura Stratton requesting the snail shell removal.
• Letter dated March 26, 2010 from Glenn Grant accepting payment terms.
• Letter dated April 20, 2010 from Glenn Grant (PCM -63) with the cost breakdown for basin 1.
• Letter dated August 28, 2010 from Glenn Grant (PCM -63 2"d Part) with the additional cost
breakdown for basin 2.
3. When the dampers in the Headworks were balanced, it was noted in the balancing report that several
of the existing dampers were inoperable. These dampers were from the original Headworks
construction and had become inoperable due to corrosion and exposure to the elements in the facility.
Eagle was requested to replace the inoperable dampers. Eagle provided a cost proposal of
$20,004.76 to complete the work.
The following documents are attached to support this change.
• RFI -110 with response from Black & Veatch dated April 22, 2010.
• Letter dated May 25, 2010 from Glenn Grant (PCM -66) with the cost breakdown.

4. Due to the corroded condition of the pressure relief valves and mud valves in the clarifiers and
existing aeration basins for treatment trains 1 and 2, Eagle was requested to replace the tops of the
pressure relief valves in all the basins and replace the mud valves and stems in the aeration basins.
The condition of the existing valves was not discovered until the existing basins were drained for
modifications during construction. Eagle provided a cost proposal of $25,956.63 to complete the
work.
The following documents are attached to support this change.
• Letter dated May 27, 2010 from Glenn Grant (PCM -67) with the cost breakdown.
• Letter dated June 3, 2010 from Glenn Grant (PCM -67R) with the revised cost breakdown.
• Letter dated June 8, 2010 from Glenn Grant (PCM -67R) with the revised cost breakdown.
• Letter dated June 23, 2010 from Glenn Grant (PCM -67R) with the revised cost breakdown.
• Letter dated June 29, 2010 from Glenn Grant (PCM -67R) with the revised cost breakdown.
5. During construction activities, it was discovered that the plug valve on the drain line for Secondary
Clarifier No. 2 was not in the location as indicated on the Contract Documents. The actual location of
the valve interfered with construction activities. The valve is required to drain the clarifier and needed
to be moved to accommodate construction activities. Eagle provided a cost proposal of $5,203.90 to
complete the work.
The following documents are attached to support this change.
• RFI -116 with response from Black & Veatch dated May 28, 2010.
• Letter dated June 8, 2010 from Glenn Grant (PCM -69) with the cost breakdown.
6. During construction activities, an existing storm drain line was discovered to be installed through the
construction area for the new Plant 4 filtration facility. This drain line was omitted from the Contract
Documents. Eagle was requested to reroute this drain line. Eagle provided a cost proposal of
$27,988.46 to complete the work. Eight days will be added to the construction schedule.
The following documents are attached to support this change.
• RFI -117 with response from Black & Veatch dated June 22, 2010.
• Letter dated July 6, 2010 from Glenn Grant (PCM -70) with the cost breakdown.
• Letter dated September 24, 2010 from Glenn Grant (PCM -70R) with the revised cost breakdown.
7. During construction activities, it was discovered that the Plant 3 influent line was not located as shown
on the Contract Documents. The new Filter backwash piping was to discharge into this existing
pipeline. Due to the changed field condition, the backwash piping was redesigned and will be tied into
a box located on the existing influent pipeline. Eagle provided a cost proposal of $21,990.15 to
complete the work.

10. Eagle requested to use a portion of the existing chlorine contact basin west wall to retain the
construction area for the new Plant 4 filters in lieu of a shoring system. Eagle made this request
because of the difficultly to install the retainage system in this area due to existing utilities. A portion
of the existing wall will be left in place. Eagle is offering a credit of $20,812.15 for leaving a portion of
the wall in place and not installing the shoring system.
