Addendum No. 2 DUE DATE FOR RESPONSES: January 22, 2016 Question Response 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. 1 Form of Tender 2.0 Appendix D, page 1 of 9 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 Addendum No. 2 PT-2015-RF-082 -2“D”? (as Appendix E is the Agreement to Bond.) 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. 2 Form of Tender 5.0 Appendix G, Page 1 of 5 Under Supporting Documentation the last box states Refer to revised Form of Tender issued as part of this Addendum. that a Bidder shall provide a completed Appendix “E”, the Appendix “E” is the Agreement to Bond, should this not be Appendix “D”? 3 Appendix B Schedule of Prices Upon downloading the above Contract PT-2015-RF- This is a CCDC 2 Stipulated Price Contract and these are Provisional 082, the only Schedule of Prices that downloaded Items. were two items for Provisional Items, where are the rest of the items for the tender? 4 E-001 to E-028 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 5 Electrical General 16010 Requirements b.iii.A.1, Page 2 Addendum No. 2 PT-2015-RF-082 Upgrade of existing 4000kva main transformers.
