BACKGROUND:
A section of sanitary trunk sewer located along the Iron Horse Trail between Gage Street and
Glasgow Street had reached the end of its useful life (+100 years old) and required
replacement. The preferred construction approach involved the abandonment of a portion of the
sewer that is no longer required and relocating existing sanitary services to the trunk sewer on
Belmont Avenue. The section of sewer, proposed to be abandoned, was located between
Glasgow Street and the CN Rail overpass. The remaining section of sewer extending to Gage
Avenue has been removed and replaced along the trail corridor.
Due to limited access to the sewer during the design stage, the configuration and condition of
the pipe was not accurately determined. When construction started, the old existing pipe was
found to be slightly oval shaped instead of round thereby requiring a different replacement
construction methodology (ie open cut instead of trenchless). The major items which resulted in
the increased contract value are:
Due to the configuration of the existing sanitary sewer, the method of construction was
changed from trenchless rehabilitation to open cut sewer installation.
An unknown and unrecorded existing storm sewer was encountered during construction.
Conflict with the new sanitary sewer required its removal and replacement. During the
relocation of the storm sewer, unknown contaminated soil was encountered which required
its removal, disposal and replacement with clean soil.
