2. Question: Under section 13420, Magnetic Flowmeter FE/FIT-202 is noted to be in a Class 1 Zone 1 location, but Drawing I-2010 shows it as being in a Class 1 Div 2 location. Please confirm if a Class 1 Div 2 flowmeter is acceptable? Answer: Magnetic flowmeter FE-202 is located in a Class 1 Group D Division 2 environment.
3. Question: Under section 13420, Subsection 2.3.4, specs state that a hard rubber liner is required. Given the filter influent media application, a polyurethane liner is more than suitable as it has excellent abrasion resistance and is a more economical option than hard rubber. Please confirm if a polyurethane liner is acceptable for FE-301? Answer: The specification shall remain as hard rubber.
4. Question: Should windows WS2 to be thermally broken hollow metal frames as shown on the schedule or Alumicor 970 series aluminum windows as per the details. Answer: All exterior windows (alum.) and doors (hollow metal) are to be thermally broken and all interior screens (hollow metal) and doors (hollow metal) are not thermally broken
5. Question: Specification Section 05600 states that the Kito ERM is the approved hoist. The problem is that they do not do Class Group & Division hoists. May we use any of the CM hoists or Stahl? Answer: The monorails are to be supplied by one of the approved suppliers listed in specification 05600. If a listed supplier is unable to provide Class Group of Division hoists, a different approved supplier is to be considered.

8. Question: On Drawing S-3070 there are two walls of the tertiary treatment building that are shown as wall type W6 and on drawing S-3080 there is a wall labeled as wall type W5; however, in the structural wall schedule for the tertiary building, there is no W5 or W6. Please clarify. Answer: Refer to the architectural drawing A-3010 for wall type information.
9. Question: Can the use of torch on base sheet and base flashings be substituted for “peel n stick” or self-adhered base sheet and flashings? Answer: Yes, typically torched on in non-combustible situations and peel and stick near combustibles

This includes surplus excavated material and imported material.
17. Question: Can cross sections or contour lines be issued so that quantities of cut/fill can be determined for the access road. (REF DRAWING C-1020 to C-1090) Answer: Delete drawings C-1020 to C-1090 R0 and C-2030 R0 and replace with drawing C-1020 to C-1090 R1 and C-2030 R1 provided as Attachment 1 to this addendum. Existing ground contours are provided on revised drawings.

18. Question: There is a discrepency for the backfill material type for the trenches between the common trench detail on the drawings, specification section 02225 clause 3.1.1.1, and specification 02735 clause 2.6.1. Please confirm if native or granular b backfill of trenches is required. (REF DRAWING – VARIOUS; REF SPEC 02225). Answer: Suitable native site material may be used for trench backfill.

32. Question:
Refer to detail 13/s-2030. Please confirm thickness and width of water stop requires as nothing specified other than suppliers.
Rev. 06.17 FO-153
Page 9 of 10
Accessible formats and communication supports available upon request.
Answer: Please refer to Detail 4 on Drawing S-3020 for waterstop specifications. The waterstops are to be SIKA Greenstreak No. 703 Ribbed Centre Bulb Waterstops or approved equivalent.
33. Question: Have a water draw down test been done to confirm the anticipated volumes of ground water and rates of flow that are anticipated for dewatering. If not can this be arranged prior to tender closing? Answer: No pumping tests have been completed and no further work is scheduled. The contractor shall be solely responsible estimating dewatering rates and obtaining any necessary permits, approvals and/or registrations.”
34. Question: For the proposed SAGR cells at the Waterford WWTF, we are to construct perimeter support walls for the walls of the cells during construction. On drawing C – 3010, it says this support wall is to be constructed of 2” x 4” framing. Although, in the specifications, division 11b-B, these drawings provided by Nexom show 2” x 6” framing for this wall. Please clarify which is correct. Answer: The construction of the wall is not in the Nexom scope of work. The project civil drawings shall be followed.
35. Question: I have a question regarding the brick veneer at the above noted project. Brick type #2 in the specifications asks for Brampton Brick, Architectural series, Wheatland velour in Metric Norman size. Although on drawing A-2050, it shows brick type #2 as a 200mm high soldier course, which would be the size of a modular brick. Also, Brampton Brick does not manufacture the Wheatland velour in a metric Norman size. Please clarify if Brick type #2 is supposed to be modular?
Rev. 06.17 FO-153
Page 10 of 10
Accessible formats and communication supports available upon request.
Answer: In lieu of Wheatland Velour (Brick #2) by Brampton Brick not being available in Metric Norman then revise to Sahara (Brick #2) by Brampton Brick to be Metric Norman. Brick height in soldier course is 290mm each and not 190mm. All elevations and wall sectional details to reflect change to higher soldier course for the Tertiary and Headworks building.
