Comments:

1 Drawing A1.02

2 What type of septic tank will be used for the “proposed buried sanitary holding tank location”?

Fibreglass Tanks being proposed / to follow section 8 OBC 3 Why are the orientations of the roof top units different

from previous drawing? Can units be lined up along or perpendicular to building grid lines?

Units to follow structural and alignments with wall below- to be coordinated in DD

4 Drawing A1.02b

5 Would locating gymnasium roof window along the south side present glare/heat issue? This location may capture most light.

Heat gains will be present affecting cooling loads- north light is more pleasant and even.

6 The parking spaces on the east side are designated in such a way that they appear to interfere with the pedestrian aisle. Is this arrangement made to accommodate the turning radius?

Turning radius is provided and Fire Truck access is proposed to terminate halfway down driveway- DD phase to optimize walkway.

7 Drawing A1.03 (Page XXII)

8 This drawing shows the abandoned pipes. Please confirm that $5.5M already covers the cost of new arrangement of two (2) 4” sanitary and storm water lines.

Is being included by Cobalt design.9 Drawing A2.01

10 Clarify “minimum code compliant” from the end user’s perspective, in particular, what does it mean to the “circulation” area, e.g. what is the average lighting level?

Average Lighting level maintained between 15 and 22 footcandles. 35 for offices. 35 for Gym

11 In the Gymnasium, how high is the glazing/viewing glass above the finished floor? Is it full height glazing? What type of viewing glass is it?

Glass will be tempered, design and height to be finalized in DD. 12 What type of wall, gypsum or concrete block in the

gymnasium? Will this withstand impact from basketball, etc?

Masonry to partial height is proposed and impact resistent drywall is an option.

13 Review to see if it is possible to relocate or reposition the double door at the NE main entrance so as to minimize potential traffic bottle neck.

This will be reviewed and revised in DD or subsequent revisions. 14 General

15 Clarify the meaning of “minimum code compliant” wherever it appears.

MNEC, OBC for Heating Cooling and Lighting. 16 Recommend to use 2 speed roof top unit for gymnasium

(the current proposed unit is a single speed CV unit)

Understood that several options will be reviewed and compared. 115 tonnes of cooling anticipated. Consider cooling temp deleted in some halls

17 Is Hydro Vault housing Hydro’s indoor transformer?

New guidelines and Codes versus existing to be applicable. 18 Where is the Boiler Room located

Boiler is not located, east area where Mechanical/ Electrical Room is shown is design starting point.

19 Class C cost estimate has not been provided. Please provide ASAP.

Class C estimate provided of May 1 design submiited on May 8. 20 Will instantaneous hot water system instead of system

with storage tank be considered, to reduce stand-by loss?

Stand by Loss and instant heat are variables of the design depending on the use- hot water boiler for kitchen likely with localized instant heat at the washrooms. Heating units at Seniors area recommended.

21 Are dual flush toilet and aerators to be used?

Dual flush toilets and aerators to be reviewed for cost and appropraitenss at DD, none are being excluded but tanked units are a base cost. Dulal flush may be confusing to use

22 Page XXIV

23 Item 6.2.6 “The main switchgear… 25% of the building load” is not required and can be deleted.

24 Confirm $5.5M includes the cost of redoing the new Hydro service.

yes, location and appearance to be developed.25 Page XXVI

26 Ensure that the selected light fixtures in “Large multipurpose” will be protected from sports activities, i.e. Are they impact resistant type fixtures?

Yes this is intended, 27 Page XXIX

28 Please submit the attachments 10.1 to 10.7 as described in Cobalt’s appendix.

These will be available in 10-15 days depending on vacations of either M+Estaff.

29 Page XXX – Mechanical Base Building list:

30 Clarify the meaning of “Delete Energy Recover….” In item 1 (Does it refer to Page 1 #5 - “Enthalpy wheel heat…” under the “list of assumptions “?)

This is a cost item, can be included as an add item 31 Clarify what is meant by “ Delete 24/7 cooling allow” in

item 2

Item was included in Hansdcomb costing and Cobalt recommend this allowance be deleted.

32 Clarify #7. Explain the meaning of “multi-use”, “unfinished” in item 3

Refers to the Gym and refers to the cooling tonnage being reduced or the median temp for design be raised from 74 deg to 80 for cost savings.

33 Where is “Reduce air distribution…” in item 5?

Budget savings achieved through large warehouse model where less ducting envisged.

34 Please provide a brief description to elaborate each of these 6 items, especially the partially deleted items.

Forthcoming

35 If we delete BAS, would Cobalt review to see if it may make sense to replace bigger roof-top units with smaller units for additional cost savings?

Yes this is possible though electrical, structural and architectural (roofing curbs) will impact the decision to be made/ recommended.

36 When BAS is deleted, do we have the two space heating boilers modulated?

BAS and Boilers can be separated, thermostat controlled. 37 Reduce mechanical cooling – Will ceiling fans be added to

improve thermal comfort?

Fans are an inexpenive method and should be an add item. 38 Page XXX – Electrical

39 We need to add back the “Prep for Electronic Security”

Clarify locations, expected security system, cabling and device requirements for door and power design requirements.

40 OK to “reduce site lighting by 50%” but bear in mind that pedestrian safety is a must. Parking lot lighting can be considered to be reduced.

Parking lighting and site lighting to safetly levels is to be maintained.41 Clarify what it means by “remove site power allowance”,

“simplification of lighting controls”, “simplification of luminaires”.

Site power for outdoor activities, trenching of services for out door power should be an add.

42 A. Architectural:

43 Item 4.2.3 and 4.2.4 - Can we use wood stud instead of metal stud? Is wood stud a much better insulator than metal stud?

Wood Stud is a better insulaor but also a combustable material and will reduce the overall permitted area on some building classifications permitting non/ wood used in long lengths less economical or available.

44 Item 5.14 - Do we have spaces for storage and collection of recyclables?

Yes this is shown in 2 areas at the south west.45 Skylights - how can we control excessive heat gain?

These will be a heat gain and blinds would be recommended46 Concrete - Will flyash, a by-product of coal burning, be

incorporated to increase the recycled contents of the concrete?

Minimal use of concrete is being employed but is preferred.
