C1. There is likely an existing municipal water main not noted on Drawings and crossing the rail corridor in the
vicinity of Station 99+956. It is expected to be below the limit of excavation for track works, Contractor to locate,
expose and confirm the location and nature of the water main in the presence of the Consultant.

A. The reference section requires the bidder to
complete a minimum of eight (8) reference projects
however on page 8 of 24 instructions to bidders it
mentions minimum of two as a General. Are we to
assume the remaining Appendix D reference
projects are for the Subcontractors?
A. Yes, unless the Bidder is designating a Subcontractor for that
portion of Work. Refer to revised Form of Tender issued as part of this
Addendum.
B. If a Subcontractor is being designated for these requirements,
please ensure that the CCDC 11 shows all of the requirements stated
in Appendix “D” – Bidders Qualifications. And state in Appendix D –
B. If so, it mentions that the subcontractors in see CCDC 11 attached for that particular Reference Project No.
Appendix G shall provide a CCDC11 with their
experience but also that the Bidder shall complete C. Yes.
Appendix “E”? (assuming this should say Appendix

C. In Appendix G page 2 of 5 to page 5 of 5, the
General Contractor is to indicate whether they are
using a subcontractor and name them here and the
subcontractor is to provide a CCDC11, does the
Bidder still need to indicate on an Appendix D the
subcontractor?, it seems redundant, please clarify.

The cables in this project are very long and
extremely heavy.
Unless noted specifically on Drawings splicing shall be avoid where it
practically possible.
These cables would take a long time to install. To
be installed in one run would require multiple days
of continuous work and leaving reels and cables
strung along the job site over nights. I am not sure
this is possible due to the restrictions on this job
site.
Metrolinx explicitly prohibits any splices below the grade.
Due to the number of manholes containing sharp
90’s we would need to use these as pull
points. That means we would have over 300m Cu
wire being pulled out of manholes and laid along the
Addendum No. 2 PT-2015-RF-082
Thank for your proposal aiming improvement of constructability and
potential saving. However Metrolinx directives shall be always
followed.
Splicing of existing and new cables is allowed only where indicted on
Drawings.
-3track to be re-fed into the manhole. During this
time the cable would be subject to damage through
unnecessary manhandling and potentially dragging
along rocks or tracks.
The weight of this run is approx. 10lbs per
foot. When you’re looking at a run that’s over 2200
I am not sure anyone has equipment capable of
pulling this cable through without risk of damage
and if you try and pull it conductor at a time I am
not sure the cable manufacturers will like the
amount of pulling tension required to install.
I would like to propose 3 splices at strategic
manholes and using epoxy filled 3M splice kits,
tested before and after each splice is completed or
another approved splicing method by Metrolinx
This would allow the installation of the cables to be
done in an efficient manner, less chance of wire
being left out of a manhole or conduit overnight,
less cable being pulled off reels and refed meaning
less potential damage during installation, The
lengths would be manageable on reasonably sized
reels, less chance of wire being damaged by the
tension on the cable because of weight. Less risk of
cable being strung all over the tracks during train
arrivals
