Owner City of Waterloo Date January 27, 2022
Project US Highway 63 Sanitary Sewer Upgrades, Phase I
Owner's Contract No. City Contract No.1037 Contractor Langman Construction Inc.
Date of Contract Start October 18, 2021 $ 7,190,038.90
You are directed to make the following changes in the Contract Documents. Description: Realign the sanitary
sewer from MH 2 to MH 10, install the sanitary sewer pipe which crosses Ansborough Avenue using open cut
methods and remove the remaining pipe borings and install them using open cut methods.
Reason for Change Order: Langman Construction proposed the removal of the pipe boring, including Ansborough
Avenue, which will result in a significant cost savings for the project. After a review of the proposal by AECOM and
City staff it was determined this proposal was acceptable. A minor realignment is required between MH 2 and MH
10 to allow for the open cut methods to be utilized in lieu of boring. A new bid item for open cut pipe installation at
Ansborough Avenue will be added to cover the extra cost of this installation. Additional rock, temporary surfacing,
utility conflicts, traffic control and traffic signal work are unique to this location and create a higher unit cost for the
pipe installation. An additional bid item for modified tee manholes will be added to replace the two (2) 120-inch
diameter manholes proposed at Manhole 2 and Manhole 8, an additional item for Class E Revetment will be added
for erosion control at the open cut pipe installation at the existing drainageways and three trees will also be added
to replace trees removed due to construction.
