Crews are hard at work building the 13 LRT stations along the alignment. This week, the next phase of station construction begins with shoring activities at Tunney’s Pasture Station and mobilization for the delivery of structural steel (in phases) at uOttawa Station occurs.
Tunney’s Pasture Station
The next phase of station construction begins with shoring activities along Scott Street. Crews also continue concrete work for the stairs and prepare to install grade beams for station footings.
Crews are hard at work installing grade beams, waterproofing the ancillary building, and constructing escalator and elevators pits.
Formwork, part of station wall construction, and concrete pours continue this week. Crews also work on the elevator pits and the track slab.
Lyon Station cavern
Architectural work progresses in the station with falsework for suspended slabs, masonry block wall installation and curb pours at the concourse level. Mechanical rough-ins also begin. Final shotcrete lining is ongoing in the west transition.
Lyon Station west entrance
The integrated entrance takes shape with work on the columns, walls, escalators and stairs, including installing rebar and stripping concrete. Formwork installation also occurs in the upper escalator and stairs areas. At the east vent shaft, crews wire saw cut and begin chipping the breakthrough area.
Lyon Station east entrance
At the concourse level, crews continue installing structural steel, form and pour knee walls* and continue electrical relocations. Wire saw cutting and chipping are completed at the HVAC shaft.
Parliament Station cavern
Station construction ramps up; crews pour elevator walls and footings for columns at one area of the cavern, while in another, they install columns and build bulkheads. Preparations begin to pour the next station deck this week.
Parliament Station east entrance
Crews continue excavation, removals and breakthrough to the tunnel below by end of week. At the east vent shaft, shotcrete work occurs this week in preparation of the next phase of excavation.
Rideau Station cavern
Progress is visible in the station cavern with the construction of bulkheads, and ongoing wall and arch concrete final lining work.
Rideau Station west entrance
24/7 construction is ongoing for the next months. Crews complete the removal of shoring and the next phase of concrete work begins on station walls and slabs, including rebar and formwork installation. At the HVAC shaft, final rock bolts are installed to allow waterproofing and concrete work for the pit to occur by the end of the week.
Rideau Station east entrance
Crews form and pour mechanical room walls, continue concrete work on the HVAC shaft walls, and install rebar and formwork for the traction power sub station walls and slab.
The next phase of station construction occurs as crews prepare for structural steel delivery in stages, during the daytime and overnight. In addition, block walls are installed, concrete work continues on station footings and walls, and duct banks and underground mechanical are also installed.
Concrete work continues on the ramp walls and slabs. Tieback drilling is completed to prepare for the next section of ramp excavation next week.
Crews pour knee walls as well as elevator and column walls, complete sections of station stair walls, and continue underground duct banks for the ancillary building.
Station construction progresses with electrical work in the ancillary buildings, roofing, the installation of structural steel and concrete suspended slab pours. Crews install panels and work on the soffit, as part of final work on the bus operators’ building.
Crews continue roofing, framing the soffit, mechanical rough-ins and electrical work, as well as assembling walls and installing elevators.
Ongoing progress includes the installation of ceiling panels, elevators and conduits, as well as final mechanical, electrical, escalators and framing work.
Construction advances in the station with the installation of the soffit, composite panels, light fixtures and doors, as well as glazing on the windscreen walls. Porcelain panel installations continue for the next weeks at the auxiliary building.
Station progress continues to be visible with the installation of light fixtures and finishing work at the lower concourse level. Work on the soffit and station stairs occurs and installation of composite panels, porcelain panels and station skylights is ongoing for the next months. Crews install the roof of the bus operators’ building, and finalize interior finishes and mechanical rough-ins.
Tunnel Excavation and Support
Weather permitting, some guideway activities will be ongoing until March, including assembling crossover tracks east of Tunney’s Pasture Station, removing parapets along Bayview Bridge, and drilling dowels and starting cable bank concrete work in the west running tunnel from West Portal moving west to Lyon Station. Crews will be back onsite in late winter/early spring when guideway activities ramp up. Train testing continues during the daytime and overnight at Belfast Yard and between Cyrville and Blair stations
Upcoming Construction Activities
In the coming weeks, the following construction activities are scheduled to occur:
- Hoe ramming as part of work on the western section of the guideway.
- Pimisi Station structural steel installation.
- Lyon Station west vent shaft work resumes.
- Activities at the Parliament Station west entrance resume with architectural work for the parapets.
- Ongoing overnight work at the Rideau Station west and east entrances, and at the East Portal.
- Ongoing structural steel installation at uOttawa Station requiring overnight lane restrictions.
- Demolition of the abutments at the Mann Avenue bridge requiring full lane closures on Mann Avenue and overnight bracket installations requiring lane restrictions.
- Structural steel installation at Lees Station.
- Fencing installation on guideway just west of Tremblay Station.
- Installation of porcelain panels at Tremblay and St-Laurent stations.
- Overhead Catenary System energized in phases for ongoing vehicle testing from Belfast Yard and Blair Station.
