Appendix A_Pages266to338_9MB.pdf - Ottawa Confederation Line

Transitway Conversion
• Conversion of the Transitway
– In open areas, ballast and track will be installed on top of the
existing roadway
– Track through the stations will be directly fixed to a concrete
slab for ease of maintenance
– Minor changes to drainage will be required
– Some structures will require modifications to increase vertical
clearances
• Once a section is converted it is unlikely that buses (or
other vehicles) will operate along that section
Construction Staging
• Staging g will be determined by the successful contractors,
but will follow these principles:
– The tunnel and underground stations will likely start first, as
these elements take the longest to construct
– The Maintenance and Storage Facility must be completed
midway through the construction of the project to allow for
vehicle delivery and testing
– Major work at Bayview, Hurdman and Blair is off the existing
Transitway and can be done with minimal disruption to bus
service
– Conversion of the Transitway will be done in logical segments to
maintain bus service on the Transitway for as long as possible
Construction Staging
• The project will be staged to:
– Minimize construction cost,
– Minimize traffic and bus service disruption,
– Optimize cash flow, and
– Maximize contractor efficiency
• Once construction starts in an area, bus service will be
rerouted
• After construction is complete there will be a 6-8 month
period for station fit-out, testing and commissioning
before revenue service starts
Rail Operations
• Track, ,power and systems installation at the
Maintenance and Storage Facility will be completed
before the vehicles arrive
• Testing in the yard and sections of the line close to the
Maintenance and Storage Facility will begin as soon as
possible
• Each section of track that is completed will require a
testing and commissioning period
• Crossovers will be provided d at the terminus stations ti and
at key points along the line to allow trains to reverse
direction
