Stage 2 LRT Project Update : July 22, 2019 to August 4, 2019

Overall

  • Preparatory activities (borehole drilling, top soil stripping, site office mobilization, preconstruction surveys, etc.) are currently underway on each O-Train extension to facilitate the commencement of Stage 2 construction activities in 2019.

O-Train Trillium Line South Extension

  • Borehole drilling between Greenboro Station and Bayview Station
    • Borehole drilling is scheduled to occur at night between late-July and mid-August between Greenboro Station and Bayview Station. This work will occur at night while the O-Train Trillium Line is not in service to minimize disruptions to transit operations.
    • Some hydrovacing is required at each station for utility investigations.
  • Preparatory works at Walkley Maintenance and Storage Facility
    • In coordination with OC Transpo Rail Operations, preparatory works such as surveying, clean up, trackwork and fencing are underway at the future site of the new Walkley Yard Maintenance and Storage Facility.
  • Uplands Structures Yard set up
    • Light post installation is now complete.
    • Crews will be connecting utilities to site trailers in preparation for occupation later this summer.
  • Jersey barrier installation
    • Crews will be installing jersey barriers overnight between late-July and mid-August at the following locations:
      • Airport Parkway
      • Uplands Drive
      • Lester Road
      • Leitrim Road
    • This work is scheduled to take place at night to minimize disruptions to local traffic.
  • Caisson drilling at future Trillium Line rail bridges
    • Caisson drilling is a method of creating structural foundations where boreholes are drilled and filled with concrete/reinforcing materials. These weight-bearing concrete columns (perhaps supplemented by steel cages or other reinforcements) can reach all the way down to the bedrock, providing for a much more stable base for large structures.
    • Caisson drilling is anticipated to begin later this summer in the following locations where new rail bridges will be constructed:
      • Airport Parkway
      • Uplands Drive
      • Lester Road
      • Leitrim Road
    • Crews have commenced construction of crane pads at all of the above locations to support upcoming drilling activities.
  • Crews have started to remove topsoil and lay gravel between Uplands Drive and the main Trillium Line. Excess soil is being trucked to the Bowesville/Earl Armstrong laydown site and stockpiled for future use. Once complete, crews will commence topsoil removal activities between Uplands Drive and Airport Station.
  • Noise and Vibration monitoring
    • Baseline noise and vibration monitoring is underway at properties near the Trillium Line alignment to ensure that construction and rail activities comply with applicable regulations and requirements.

O-Train Confederation Line East Extension

  • Borehole drilling is currently underway along OR 174 between Blair Road & Trim Road (night work).
  • Pre-construction surveys
    • East-West Connectors (EWC) have retained DST Consulting Engineers to carry out a pre-construction survey of the homes and buildings located within close proximity to the project. They will be documenting properties to establish the existing conditions of the interior and exterior of buildings near the alignment, prior to construction.
  • East day-to-day work yard set up (Montreal Road and OR 174)
    • Crews have completed the installation of the granular pad and fencing.
    • Utility work and site servicing to follow.
    • This site will be used for the coordination of Confederation Line East construction activities support temporary modular trailer complex, parking spaces and a day-today yard.

O-Train Confederation Line West Extension

  • Borehole drilling is currently underway in the following locations:
    • Lincoln Fields Station
    • Between Pinecrest Station & Connaught Tunnel
    • Bayshore Station
    • Lincoln Fields Tunnel Portal
    • West of Moodie Station
  • Sir John A. Macdonald Parkway Cut and Cover Tunnel Preparatory Works
    • The Sir John A. Macdonald (SJAM) Parkway is shifting north to accommodate the space required to construct a cut-and-cover tunnel between Dominion Station and Cleary Avenue.
    • Crews have commenced preparatory activities to realign the SJAM by installing signage, fencing and temporary concrete barriers.
    • Topsoil removal is underway.
    • Roadworks are anticipated to begin in areas where topsoil removal has been completed.
    • Off-peak lane reductions between Dominion Avenue and Cleary Avenue are anticipated to occur until late October. Eastbound and Westbound traffic will be maintained at all times.
    • The City of Ottawa continues to coordinate with the NCC's Public Affairs Office to provide appropriate public notification (signage, resident notices, web updates, etc.)
  • West day-to-day work yard set up
    • Work has commenced to construct granular pad near Baseline Road and Navaho Drive/Transitway to support temporary modular trailer complex, parking spaces and a day-to-day yard.
    • This site will be used for the coordination of Confederation Line West construction activities.
  • Building demolition
    • Building demolition is scheduled to occur in September 2019 within the project limits:
      • On the east side of Connaught Avenue between Severn Avenue and Hanlon Avenue (three houses)
      • On Richmond Road, east of Cleary Avenue (one strip mall).
  • Rochester Field Archeological Investigation
    • In coordination with the NCC and local indigenous stakeholders, EWC is performing an archeological investigation at Rochester Fields.
    • Once complete, work will commence to transition this location to a laydown area.
  • Pre-construction surveys
    • East-West Connectors (EWC) have retained DST Consulting Engineers to carry out a pre-construction survey of the homes and buildings located within close proximity to the project. As indicated in the east update, DST will be documenting properties to establish the existing conditions of the interior and exterior of buildings near the alignment, prior to the start of construction.
