Response: During the first stage we did a desktop exercise which<br />
used previous databases for contaminated sites,<br />
borehole information, etc. Once the alignment was<br />
defined, additional work was undertaken. Our work<br />
built on the previous studies.<br />
Question: Will EA consider the changes in transit patterns while<br />
construction is on-going?<br />
Response: Yes, will look at impacts to transit users and consider<br />
duration, bus routings, etc.<br />
Question: Will traffic impact to local streets be looked at?<br />
Response: Yes, OC Transpo has done some work as to where<br />
buses will go during construction. Provincial interest is<br />
at a higher level, not specific road corridors or<br />
locations. Diversions may have a large impact but<br />
they are of a short duration.<br />
Question: Will construction be done in increments, or will whole<br />
corridor be closed at once?<br />
Response: Construction will likely be incremental, starting with<br />
tunnel, M&S facility and major stations where work<br />
can be done off-line, without impacting traffic and<br />
transit operations. Transitway would be closed in<br />
logical segments. When the work is finished the whole<br />
line will open up at once. The final procurement<br />
strategy may alter this general approach, and the<br />
successful contractor may decide on a different<br />
approach.<br />
Question: Will project use one tunnelling machine or two? How<br />
will tunnel be constructed?<br />
Response: That will be a contractor decision. Using one machine,<br />
it would start at LeBreton, tunnel under downtown and<br />
be pulled out either at Campus Station or the Mann<br />
Ave. portal and be returned to LeBreton for the second<br />
run. Two machines would operate in parallel, also<br />
starting from LeBreton, with one machine being<br />
launched 3-4 months before the second one.<br />
Contractor will have to decide on best approach.<br />
Short length of tunnel will likely not provide an<br />
advantage to using multiple machines.<br />
Question: Where are the “ugly” parts of the project going to be?<br />

Question: What is the duration of activities downtown?<br />
Response: 18-24 mos. Depends on complexity involved at each<br />
location.<br />
Question: 18-24 months at each station? Will this be concurrent<br />
or overlap at all?<br />
Response: It is likely that the construction of the underground<br />
stations will be slightly staggered, but there will be a<br />
time when all are under construction at once. The<br />
exact details will depend on contractor.<br />
Comment: Utility relocations, etc. will also need to be done.<br />
Response: The integration of station accesses and vent shafts<br />
into existing buildings or vacant sites would help limit<br />
disruption as they would not impact utilities under the<br />
City’s roads. Those trade-offs come later.<br />
Comment: City is gathering more detailed geotechnical<br />
information this year. Borehole drilling will have some<br />
disruption and will likely occur within the next several<br />
months.<br />
Public Open House #4<br />
The next Public Open House will be on 23 February 2010, from<br />
5:00 p.m. to 8:30 p.m. There will be no presentation component<br />
to this event. The focus of this Open House is on the provincial EA<br />
process and requirements.<br />
Process Moving Forward<br />
Key dates:<br />
Public Open House – 23 February 2010<br />
Draft Environmental Project Report available – March 2010<br />
Notice of Completion (initiates 30-day public review) – April<br />
2010<br />
Comment: From an official perspective, this is the final meeting<br />
of the BCG. All BCG members are stakeholders in the<br />
project, please bring forward any issues you still have<br />
during the EA process and we will consult with you on<br />
an individual basis.<br />
Comment: Concerns have been raised previously. And we will<br />
assume that they will be addressed without being<br />
raised again.<br />
Question: Is the provincial EA process being used the speeded<br />
up one?<br />
Response: Yes. The project is following the new provincial<br />
process for transit projects, which not only speeds up<br />
the process, but provides definitive timelines to the<br />
proponents.<br />

Response: The TBM launch site (LeBreton) will be a major<br />
construction site. Major station sites will also require<br />
significant construction. Use of a TBM will mean less<br />
disruption downtown but access shafts will require<br />
disruption at localized spaces above each of the<br />
downtown stations.<br />
