LRT construction progresses along the alignment: crossover tracks continue to be assembled east of Tunney’s Pasture Station, construction of Pimisi Station walls and slabs ramps up, structural steel installation is ongoing at uOttawa and Hurdman stations and glazing for the Blair Station skylight occurs.
Tunney’s Pasture Station
Crews continue concrete works at the station. Work includes installing rebar and forming pier columns, pouring concrete for the walls and stairs. Shoring for the retaining wall and underground mechanical and electrical work also occurs.
Station construction advances with the installation of grade beams, work on slabs as well as escalator and elevator pits.
Progress continues to be visible with final foundation construction occurring. Crews are also installing duct banks, continuing mechanical work at the lower concourse and pouring slabs.
yon Station cavern
Crews continue architectural work – including mechanical rough-ins and masonry block wall installation – begin waterproofing activities and prepare to install the escalators.
Lyon Station west entrance
Integrated entrance construction progresses with concrete work on escalator and stair walls, followed by curing and stripping by end of week. At the east vent shaft, crews complete wire saw cutting and continue waterproofing.
Lyon Station east entrance
Crews continue installing structural steel at the concourse level and prepare to pour the deck, cure and strip in phases and install floors. At the HVAC shaft, crews continue chipping concrete and install rebar and waterproof for the next weeks.
Parliament Station cavern
Construction in the cavern ramps up with concrete arch final lining, deck pours, installation of rebar on footing for the next pillar, work on bulkheads, and the beginning of shoring for the next section of deck work.
Parliament Station east entrance Soft ground excavation and removals for a final breakthrough to the tunnel below take place this week. At the east vent shaft, waterproofing activities are ongoing until the end of the month.
Rideau Station cavern
Work continues to advance in the cavern with final lining arch and wall concrete pours.
Rideau Station west entrance
Crews install rebar, followed by waterproofing activities on station walls, and chip and remove the shoring system. Work progresses at the HVAC shaft with rebar and formwork installation on walls.
Rideau Station east entrance
The integrated entrance continues to take shape; work includes the installation of rebar for the mechanical room and lower level walls and slabs. Traction power sub station walls and slabs are also being formed and poured this week and work on the station stairs continues.
The first section of station structural steel continues to be installed and work on footings and the pedestrian underpass, as well as excavation of the stairwell, rough-ins in the lower level and masonry, are ongoing
The roadheader begins mining a section of the ramp this week. Crews also continue installing rebar and formwork, and waterproofing walls and slabs during the daytime and overnight as required.
Crews continue working on the ancillary building, the communications rooms and the station foundation and columns for the next weeks.
Construction continues to advance with the installation of structural steel at the east end of the station, waterproofing, electrical work and rough-ins at the ancillary buildings, as well as concrete work for station stairs and suspended slabs. The bus operators’ building takes shape with the installation of windows and floor tiles.
Roofing, soffit framing, the delivery and installation of windscreen bases, work on platforms, and the installation of elevators take place this week. Crews continue installing equipment for the communications room for the next weeks.
Construction progresses at the station with the installation of ceiling panels, doors and light fixtures in phases, mechanical and electrical work in the secondary rooms and pulling wires.
Crews are hard at work installing ceiling panels and continue working on the soffit, installing composite and porcelain panels, glazing, painting at the elevators, constructing precast concrete stairs and installing light fixtures in phases.
The station continues to take shape with glazing for the station skylight, work on the soffit, the installation of composite and porcelain panels, as well as tiles at the lower levels, completing work on elevators and stairs, and beginning work on escalators. Interior finishing, including tile installation, is ongoing at the bus operators’ building.
In the running tunnel west of Lyon Station cavern, trackwork crews begin working on the concrete track slab and continue final shotcrete lining in the west transition to the cavern. 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 arch final concrete lining work occurs.
