This week on the Confederation Line project, construction takes place on the envelope for the head house at the east entrance of Rideau Station, and the adit upper walls are being formed and poured. In the west, permanent power is now on at Pimisi Station and crews at Bayview Station are busy with mechanical and electrical work. In the east, at Tremblay, current work focuses on handrail posts at stairs, the windscreen posts, and the artwork supports.
Tunney’s Pasture Station
The bus loop progresses with construction of the bus operator, maintenance and supervisor buildings. The duct bank to the bus loop is also being completed. Mechanical and electrical work is ongoing.
Crews continue to frame the north roof at Bayview Station. Installation of porcelain panels for the stairways is ongoing, as is mechanical and electrical work.
Crews are working on ceiling framing on the platform, the heat tracing installation, and pulling wires for communications. Fascia and soffit are being installed on the eastern side of the station. Permanent power is now on at Pimisi.
Electrical and communications installations, art painting, and ceiling framing are underway throughout the entire station. Elsewhere, TVS axial fan installation is underway.
Bike rail installations begin this week, stairways progress and so does escalator installation. Mechanical, electrical and plumbing rough-ins continue all throughout the station.

At the platform level, rebar for the invert is installed and concrete pours will occur next week. Arch waterproofing and installation of the access platform will also occur in the coming week.
Rideau Station east entrance
At grade level, construction commences on the head house envelope. Throughout the entire station, mechanical and electrical installations, stair construction and tiling are underway. The elevator divider beam is installed and adit upper walls are formed and poured.
Concrete backfilling and waterproofing continue this week. Soil backfilling will occur in the spring.
A pour of the eastbound platform is expected to take place. Crews continue to make progress on the steel mullions, the wood ceiling framing, and the accessibility ramp and stairs.
There is ongoing preparation for the topping slaps. Crews are also working on composite metal panel (CMP) installation. The east entrance stairs continue to take shape with a first pour coming shortly.
The mechanical rough-ins continue, there is ongoing work on two of the elevators, and crews are running conduit below the guideway. Crews are also completing the artwork support installation and completing the framing for the east auxiliary building.
Crews continue to work on the shroud at the south elevator tower. They are putting in handrail posts at stairs, completing the windscreen post installation, and continue working on the artwork supports.
Crews are putting in porcelain panels at the platform level and scaffolding at the stairs in the plenum area. Installation of the lantern structure for the north side is also underway.
The current work focuses on ceiling framing, architectural finishes, glazing and preparations for the signband.
Testing and commissioning of mechanical and electrical equipment is ongoing. In addition, installation of the signband, and finishing the stainless steel elevator architectural panels occurs.
Guideway and Trackwork
In the tunnel, crews continue to work on the track slabs between Parliament Station and Rideau Station, and dowel installation occurs between Lyon Station and the West Portal. In the West, activities include rail installation at Tunney’s Pasture. Train testing continues on the eastern stretch of the alignment.

In the coming weeks, the following construction activities are scheduled to occur:
- Wood ceiling installations at the eastern stations
- Installation of signband and entrance lanterns at the eastern stations
- Installation of porcelain panels and glass panels at uOttawa Station
- Installation of stray current monitors at various locations
- Parliament Station West TVS breakthrough
