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 />
