O-Train Stage 2 Light Rail Transit Project Quarterly Update

Stage 2 Trillium Line Project

  • The City has been working closely with TransitNEXT to advance critical works that would
    enable the handover of the system to the City this year. Based on the current review of all
    inputs including an agreement on the training requirements, the updated working timeline for
    the project handover is before the end of the year.
  • Note that this timeline is based on the information we have available and assumes that
    completion of remaining milestones will be relatively smooth. There remains some risk and
    uncertainty in the completion of the remaining works.
  • The achievement of the handover milestone is contingent upon:
  1. successful completion of signal testing
  2. successful completion of systemwide commissioning including stations
  3. regulatory approvals by Transport Canada
  4. training completion
  • Trackwork is largely complete; however, progress on signal testing is advancing slowly and
    requires additional time which is pushing the overall handover timeline to no sooner than early
  • Staff also continue to monitor progress at stations noting that all stations still require
    occupancy permits and all stations require TSSA approvals for elevators
  • Subsequent to project handover, the City will make an assessment regarding the timing for
    start of public service. Final readiness activities and an assessment of system performance
    and system maturity will be made after handover from the build team.
  • Staff worked with TransitNEXT in Q2 2023 to continue resolving open comments for stations,
    guideways, and maintenance facilities. Staff reviewed issues for construction drawings for the
    Hunt Club Rail Bridge and the final design submissions for the communication systems.
  • Final signage and wayfinding shop drawings for the stations and Walkley Maintenance and
    Storage Facility (MSF) have also been submitted by TransitNEXT for a final accuracy review
    by Transit Services.
    Construction – Highlights
  • During Q2 2023, the construction of all 13 Trillium Line stations continued, including elevator
    installation, platform work, utilities work, aluminum composite panels (ACM) and shelter
    installation, painting, glazing installation, communications cable pulling, mechanical,
    electrical, and plumbing work. Building Code Services (BCS) occupancy permit readiness
    meetings and deficiency closeouts for Airport, Greenboro and Carleton Stations started during
    this period with partial BCS occupancies targeted for end of Q2 2023.
  • Civil works at Leitrim Station and Bowesville Park and Ride started during Q2 2023.
    Permanent fence posts installation along sections of the guideway continued in Q2 2023.
    Operational signage installation started along the guideway during this period.
  • Works progressed at the new Albion Yard Facility (formerly called Walkley Maintenance and
    Storage Facility), including Mechanical, HVAC and Electrical deficiencies closeout,
    commissioning of the HVAC system and wayside cabinets continued. Work continued in the
    train wash building with deficiency closeouts and train wash equipment installation started at
    end of Q2 2023. Electrical, mechanical and HVAC rough-in scope progressed at the
    inspection building during Q2 2023, overhead doors and wayside cabinets were installed at
    the inspection building as well.
  • Trackwork progressed along the north section of the alignment (Segment 2) including track
    welding, destressing, and final surfacing. The south section of the alignment was provisionally
    completed with the tonnage run being completed as well. Vehicle testing continued between
    the Walkley MSF and Limebank Station. Airport elevated guideways trackwork was
    provisionally completed. The first train was sent out to the Airport Station during Q2 2023.
  • Following the completion of construction and then testing and commissioning program,
    TransitNEXT will begin a three-week trial running period to validate that all aspects of the
    system and maintenance activities perform as expected.
  • Following the successful completion of Trial Running as well as completion of all PA
    requirements, Substantial Completion will be achieved.

The system will then be available for OC Transpo to complete any remaining operational
readiness activities before determining a final opening date to the public. The duration of this
final process for validation of system readiness is still to be determined.
Stage 2 Confederation Line Project

  • The East extension is currently forecasting a completion date in Q1, 2025, which is
    approximately 7-week delay from the Project Agreement (PA) completion date of November
    26, 2024.
  • On the West extension, from Tunney’s Pasture Station to Moodie and Algonquin Stations, the
    City is currently expecting a delay of up to 17 months against the contractual completion date
    of May 25, 2025. Specific elements such as the Moodie Light Maintenance and Storage
    Facility (LMSF) and Lincoln Fields Station are progressing well. Production rates and
    accumulated delays on the Cut and Cover Tunnel along the Sir John A. Macdonald Parkway
    and Byron Linear Park are pushing the overall project completion date to late 2026.
  • Note that the project has two independent opening dates, with the eastern extension segment,
    from Blair Station to Trim Station, planned to open first.
  • In Q2 2023, City staff continued their review of EWC’s designs of specific Confederation Line
    extension elements, including stations. The focus is now on closing open comments on design
    packages. In Q2 2023, staff continued the review of design documents for stations and
    remaining roads packages.
  • The review of design for other works that can be completed following Substantial Completion,
    including the Richmond Road Complete Streets and the decommissioning of portions of the
    Transitway, will continue in Q3 2023.
  • There is now a focus on review of testing and commissioning plans and documents.
    Construction – Highlights
  • In Q2 2023, work continued throughout the west extension, including:
    o PCL mobilization at New Orchard and Kìchì Sìbì Stations
    o Structural work for BOBs at Lincoln Fields and Moodie Stations
    o Concourse pour at Queensview Station
    o Station servicing for Pinecrest Station
    o Roofing and glazing at Moodie Station
  • Bulk excavation in the existing transitway trench between Kìchì Sìbì and Tunney’s Pasture
    Stations progressed in Q2 2023 and bulk excavation is complete. Drainage work and
    rehabilitation of the trench walls including scaling and installation of anchors, shotcrete, and
    drapery continues in the trench.

In the west, rail welding and installation began in Q1 2023 and has continued throughout Q2

  1. Energization of the Servicing and Inspection building of the LMSF is complete. The
    infrastructure maintenance building and signals building were also energized in Q2 2023.
    Catenary poles and catenary work are expected following installation of rail this spring.
  • In the east, the majority of the 23-kilometre guideway barrier wall between the rail guideway
    and the highway has been completed with some expectations for station/guideway entrances.
    Fence installation on top of the barrier walls will continue in Q3 2023.
  • Overhead Catenary System (OCS) Messenger Wire installation has begun between Montreal
    and Jeanne d’Arc Stations and will continue in Q3 2023.
  • Racks and cabinets insllation in the communications room and cable pulling continued in east
    stations and will continue in Q3 2023. Communication device configuration work has begun
    and will continue in Q3 2023.
  • Track installation between Trim and east of Place d’Orléans stations continued and is nearing
    completion. Eastbound trackwork between Jeanne d’Arc and Place d’Orléans stations has
    begun and will continue in Q3 2023.
  • Finishing works at Montréal and Jeanne d’Arc stations continue. Concourse level pour and
    structural steel installation at Convent Glen Station were completed in Q2 2023, mechanical
    and electrical work will continue in Q3 2023. Electrical and mechanical rough-in work, finishes
    and glazing work is ongoing at Place d’Orléans Station. Structural steel work has been
    completed and glazing and exterior cladding work has begun at Trim Station.
    The handover sequence for the Stage 2 Confederation Line is different from, and includes lessons
    learned from, Stage 1. Following completion of the infrastructure and system commissioning by
    EWC, a three-week trial running period involving City operations, Rideau Transit Group (RTG),
    Rideau Transit Maintenance (RTM) and East-West Connectors (EWC) will be completed to verify
    operation and maintenance of the completed system. Following this work, additional time may be
    used for trial operations prior to opening for passenger service.
    Stage 2 Project Vehicles
  • RTG is providing 38 additional Alstom Citadis Spirit light rail vehicles to ensure that the
    expanded Stage 2 Confederation Line operates as a single, uniform service. To date, 13
    additional vehicles have been accepted and are in use as part of the operating fleet.
  • Configuration updates, software change, reliability and performance modifications that have
    been identified through Line 1 service since 2019, are being applied to the Stage 1 vehicles
    and to the Stage 2 vehicles in order to create a homogeneous fleet. The Stage 2 vehicles will
    need to be retrofitted with new axles once the updated design is available.
  • Additional vehicles are undergoing final commissioning now and the fleet size is expected to
    be sufficient for the east extension by the end of this year. The remaining fleet order is expected to arrive well ahead of the west extension timelines.
  • TransitNEXT have supplied seven Stadler FLIRT vehicles for the expanded Trillium Line, which were already delivered to Ottawa. The existing Alstom LINT fleet have undergone a retrofit program and are now ready for systemwide testing and commissioning.

Stage 1 and Stage 2 Contingency Funds
The Stage 1 Confederation Line contingency fund is $115 million. To date, $100.68 million from
the total fund has been spent. Remaining funds are primarily related to property requirements
and remaining commercial matters.
The original Stage 2 contingency fund of approximately $152 million was increased by $25 million
due to unforeseen costs and improvements to the project, as approved by Council on July 6, 2022.

Approximately $173 million of the Stage 2 contingency fund has been committed to date. An ongoing budget pressure exists for City costs due to project delays and the additional costs
for City oversight, existing and emerging variations for system improvements and lessons
learned, residual project risks, as well as new and emerging commercial issues. A budget report,
detailing a summary of costs to date, a lookahead for future costs, and an approval request to
address the budget pressure, is planned as part of upcoming budget processes.

Stage 1 and Stage 2 Capital Budgets
In keeping with Council’s approved 2017 Stage 2 Report (ACS2017- TSD-OTP-0001) and 2019
Stage 2 Report (ACS2019-TSD-OTP-0001), approximately $3.171 billion has been spent as of
June 30, 2023 and relates to the RTG MOU for Belfast Yard and vehicle assembly mobilization
($431M), Confederation Line extension mobilization and construction period payments
($1.650B), Trillium Line extension construction period payments and financial close for the
Revenue Vehicle Supply Contract ($611M), and contingency ($71M). The remaining $408 million
was spent for planning, procurement, project delivery and City retained scope.
