This week on the Confederation Line, escalators are an over-arching theme, with the installation of the first escalators at Rideau Station east entrance concluding at the end of the week. At Hurdman Station, the second escalator installation is just beginning, and at Parliament Station west entrance escalators are being delivered. Meanwhile, Tunney’s Pasture Station shapes up with structural steel, falsework and stair forming.
Tunney’s Pasture Station
At the platform level, construction progresses with work on the walls and installation of plumbing and electrical duct banks. Structural steel and falsework continue to shape the concourse. Forming of station stairways continues.
Structural steel installation continues. The roofing and painting for the upper ancillary building is ongoing as well. Work progresses to ready the sewer and water main, as well as to prepare the duct bank.
The structural steel is set to be completed in the coming weeks. The east concourse slab is poured and concrete work is nearing completion. Work on the elevator shaft is underway and installation of the roof parapets is concluding.
Lyon Station cavern
Work continues with mechanical, electrical and architectural installations at the west and east end of the station. Crews build formwork for the remaining curbs and slabs at the platform and concourse level, and pour the topping slab in the service corridors.
Lyon Station west entrance
Work is ongoing with temporary landscaping around the perimeter of the station and site clean-up around the station’s exterior. Progress on the elevator shaft wall is made as well.
Lyon Station east entrance
Mechanical mezzanine waterproofing occurs this week. At the east TVS, the second concrete pour is underway with rebar installation, followed by formwork and concrete pours at the beginning of the week.
Parliament Station cavern
At the platform level, escalator concrete pours, staircase layouts and conduit installation takes place. At the concourse level, in addition to the activities above, crews begin building formwork for HVAC room curbs and prepare for elevator shaft steel installations.
Parliament Station west entrance
The west entrance breakthrough is on the horizon for Parliament Station as work nears completion. Meanwhile, escalator deliveries take place at the end of the week and excavation for the mid-entrance progresses with rock excavation, hoe-ramming, rock bolts and shotcrete.

Escalator installation prevails this week. Waterproofing the west wall, pouring curbs alongside the stairs and shoring removal along the station’s west side is ongoing. Finally, excavation of the adit advances with rock bolts and shotcrete.
Ongoing activities at the East Portal include rebar and formwork for the slabs in the tunnel, mechanical and electrical work, and rebar, forming and pouring the u-trench west wall.
Ballast and track through the station has begun, as has installation of the curved plaza ramp. Structural slabs at the station will be completed shortly. The painting at the platform level is ongoing, as is the electrical room installation. Jersey barriers along Nicholas Street will be poured in the coming weeks.
The duct bank work will be completed soon and roof installation progresses. Structural steel installation is ongoing and so is the ancillary building electrical and plumbing work. Crews are completing the floor in the communication and electrical rooms.
This week at the station, the second escalator is scheduled to be installed. The high roof parapet framing is ongoing, and windscreen post bases are being installed on concourse and platform levels. Composite panels on the two stairways are progressing.
Framing for the metal composite panels continues and is almost complete. The windscreen posts, elevators and mechanical and electrical rough-ins continue to be installed. Crews are also getting the second elevator up and running.
Platform level work is ongoing, including windscreens, electrical and sprinkler installations. Installation of porcelain panels is ongoing and slab pours are expected to commence in the coming days.
The pour for the platform topping is expected to take place this week. There is ongoing work to install the precast concrete and signband conduit. Installation of select light fixtures is continuing and fabrication of select porcelain panels is complete.
Sand blasting on the platform and upper concourse is taking place. Clear coating concrete will commence right after sand blasting. Glazing for the windscreen walls, around stair openings, bridge and the remaining glazing for the elevator shaft will be starting next week after floor protection is complete. Remaining railing posts to be installed soon.
The work on the guideway continues with train testing now expanded almost to Tremblay Station. Trackwork activities occur from just east of uOttawa to Lees Station, with trackwork continuing in the tunnel as well. In the section of the guideway from uOttawa to Hurdman Station, tamping up to Rideau River nears completion. Drilling is nearly complete for the track plinths at Tunney’s Pasture Station and pull tests are ongoing at the diamond crossover.
