Addendum No. 1

Tender No. 194-2016

Re: New Emergency Gas Generator Installation at 12 Canterbury Place, Fire Hall 114, Toronto.

Closing Date: 12:00 P.M. Noon (Local Time), May 19, 2016

Please refer to the above Tender Call document in your possession and be advised of the following information: 1. General Clarifications To Questions From Bidders

Q1. For Drawing M-1, I have attached the mechanical iso. What is #2 not shown on

legend. #1 is a gas relief valve? If so does Enbridge supply with station?

A1. This scope is part of the Enbridge work in which the contractor will need to retain via the cash allowance.

Q2. On tender 194-2016 the fine print on drawings E-1 thru E-4 is not legible. Looks like it’s just from the copier. Could more clear drawings be distributed?

A2. Drawings E1-E4 are attached, all dated 2016/02/12. (Enclosed 4 pages)

Q3. Drawing M-1. If #1 is a pressure regulating valve please provide requirements (load and pressure drop).

A3. Same as above response A1. This scope is part of the Enbridge work in which the contractor

will need to retain via the cash allowance.
