Subject: Sanitary Sewer Improvements FY 2015 Phase II CIP Pipe Lining Project
Change Order No. 3
City of Waterloo, Iowa
City Contract No. 876
AECOM #60339160
Dear Mr. Hoambrecker.
Attached is Change Order No. 3 for the Sanitary Sewer Improvements FY 2015 Phase II CIP Pipe Lining
project. The following is included in this Change Order
1. Deductions for CIPP segment removals due to damaged pipe. These segments could not be Tined.
2. Addition for pipe cleaning associated with the damage pipe deductions. The contractor must clean the
pipe segments prior to completing the Pre -Televising work. The contractor spent time cleaning the pipe
before the damage was discovered. Cleaning is incidental to the CIPP lining and the contractor would
not be paid for this work. The contractor requested to be paid for this work that is no longer covered
under the CIPP bid items.
3. Reconciliation of the Bid Quantities and Change Order No. 1 and 2 Quantities to match quantities
installed.
AECOM recommends that the City of Waterloo authorize Change Order No. 3 for the deduction amount of -
$30,388.65 decreasing the total project cost to $1,734,590.95.
Yours sincerely,
Christopher G. Oelkers, P.E.
