The project
This multi-year project involves the complete
replacement of the Turcot Interchange, which was
built in the late 1960s. The Government of Quebec
awarded the contract to KPH Turcot, which was a
consortium of major construction and engineering
firms including Kiewet, Parsons, WSP and Holcim.

The freeway interchange was made up of three-levels
of overpasses linking the north-south Highway 15 to
east-west Highways 20 and 720 as well as the
Champlain Bridge.

structures associated with a major civil construction
project in Montreal, Quebec.
In general, there were fifteen (15) structures to
demolish, which included about 6 km of overpasses
as well as a railway tunnel. The quantity of concrete
debris was approximately 360,000 tonnes, which was
crushed and reused on-site.

As the new roadways were completed and opened to
traffic, Delsan-AIM undertook the demolition of the
old overpasses, which were built using reinforced
concrete box girders that were supported by concrete
piers and abutments.

Delsan-AIM collaborated with various engineering
firms to develop plans and procedures for each stage
of this challenging project, which included work near
live roadways, newly built overpasses as well as other
existing live infrastructures, such as railway lines.
Through this collaboration, some innovative
equipment was designed and built especially for this
project. Flat-bed trailers, for instance, were equipped
with hydraulically operated deflectors, which were
strategically positioned below demolition operations to
prevent any damage to retained structures.

Delsan-AIM performed the bulk of the work using
excavators equipped with specialized attachments
including high-reach booms as well as mobile cranes,
which were used in certain locations to perform
selective removal operations. The work was
completed in shifts working around the clock during
roadway shutdowns.
