This week, crews prepare to install masonry at Pimisi Station, the elevator at Lyon Station and hardware and doors at St-Laurent and Cyrville stations.
Tunney’s Pasture Station
Construction of the station advances with concrete work on walls at the north side platform area. Crews also continue forming stairs and shoring for the retaining wall.
Crews continue underground electrical and mechanical work, installing grade beams for the concourse level, and working on escalator and elevator pits.
Lyon Station cavern
Architectural work advances in the cavern, including concrete pours for curbs and slabs and mechanical rough-ins at the platform level. At the concourse level, crews install a small crane for the elevator installation that begins this week.
Lyon Station west entrance
Concrete work ramps up for the next weeks at the integrated entrance as crews form and pour the upper escalator and stair area walls and raft slab. Crews cure and strip the newly poured deck this week. Chipping takes place at the east vent shaft in anticipation of a complete breakthrough from the surface to the tunnel below.
Lyon Station east entrance
Integrated entrance construction continues to progress with the installation of structural steel and concrete work including rebar and formwork for perimeter walls at the concourse level. At the HVAC shaft, crews continue waterproofing and begin concrete works.
Parliament Station cavern
Crews continue work in the cavern, including building and installing bulkheads, arch pours, in addition to shoring and rebar for the next section of deck.
Parliament Station east entrance
Integrated entrance work is ongoing and includes removal of the shoring system, excavation and removals, hoe ramming and line drilling in phases. At the east vent shaft, waterproofing is completed and crews begin installing rebar and formwork to allow for concrete pours
Rideau Station cavern
The cavern continues to take shape with crews installing rebar and pouring arches and walls in sections. Construction of bulkheads also occurs.
Rideau Station west entrance
Construction continues at the integrated entrance with the installation of rebar and concrete pours for the raft slab, waterproofing of the north and south walls and shoring removal to allow for the next phase of concrete works to begin. Crews install rebar and pour concrete walls at the HVAC shaft.
Rideau Station east entrance
Progress is visible as station walls and slabs are poured and existing whaler beams are removed as part of the next phase of work.
Crews continue installing structural steel, including for the elevator areas, pouring concrete for the north foundation wall at the pedestrian underpass, and working on masonry walls and concourse rough-ins.
Work advances at the ramp and includes the installation of rebar, followed by concrete pours of walls and slabs, in addition to mining of the ramp during the daytime and overnight.
Foundation work continues for the station’s ancillary building this week, in preparation for the next phase of station construction, including the installation of structural steel. Crews also complete the installation of duct banks.
Progress continues to be visible at the station with the installation of structural steel, suspended slab concrete work, curb pours at the stair area and waterproofing, as well as ceiling and electrical work at the ancillary buildings. Internal finishing work, including wiring and tiling, is ongoing at the bus operators’ building.
Crews continue installing windscreen bases, working on roofing, framing the soffit, pulling wires and installing equipment in the communications room. Elevator installation is also being completed this week.
The station continues to take shape with the installation of ceiling panels, doors, hardware and light fixtures, in addition to mechanical and electrical work. Tiling begins in the secondary rooms this week.
Construction is ongoing at the station with work on the soffit and stairs, the installation of ceiling panels as well as composite and porcelain panels, glazing, painting, and the installation of doors, light fixtures and hardware, in sections.
Crews are hard at work completing the soffit, glazing, installing composite and porcelain panels and tiles at the lower levels, working on elevators, and installing doors and hardware.
In the running tunnel west of Lyon Station cavern, guideway activities are ongoing, including concrete pours for the track slab. In the running tunnel east of Lyon Station, crews pour concrete cable bank walls in preparation for future guideway work in this section. Just east of Parliament Station, waterproofing continues as part of arch final concrete lining work.
