2 GOVERNMENT SERVICES #18, #27, #1 REHABILITATION Page 1 of 6 Q1 - I was wondering if we can expect an extension on Bar U Ranch. We have a couple of sub-contractors who will drop the tender if they can't find more time to complete the bid and I just would like to let them know as soon as I can. A1 - Refer to the front page of the tender for the closing date. Q2 - Addendum #1, Page 2: From (Addendum #1), please provide quantity and specification for the new stones to be replaced as per A2 - The specification for the stone is in Specification Section The quantity assumed is listed under the amounts In the unit price table. Q3 - Can you please advise the value of the Slaughter House and Implement House in $ amount for insurance purpose? A3 - No, we do not have an assessed value on file. Q4 - I am writing to discuss the Historic Repainting of Exterior Surfaces (090361) at the Bar U Ranch. The system requested is no longer available in Canada, for the linseed oil paints requested no longer meet Canada s VOC regulations. I would like to propose a new system that will meet the durability requirements, historic appearance, and meet today s standards for VOCs. a. One (1) coat Boiled Linseed Oil diluted 25% with mineral spirits *for conditioning of wood and deep penetration of new and old surfaces to prevent drying out and cracking b. One (1) coat Sherwin-Williams Exterior Long Dry Oil Based Primer ( ) *to penetrate deep into the wood for maximum adhesion c. Two (2) coats Sherwin-Williams Duration Exterior Flat Paint ( ) matched to historic red colour *this flexible topcoat will prevent any cracking, peeling or blistering while holding its colour for a considerably longer period of time (compared to oil paint). I have attached the specs sheets sent with this question: A4 We do not agree with the proposed specification modification. Changes have been made to the specifications to address VOC concerns. Please review the specification modifications included with this addendum.
