Do you mean that we have to put a full copy of the specs in our Tender document? If so, it would be a very large document and we don't see the point of sending the specifications back to you and including them in our Tender package. Could you please clarify? Answer: Delete – sentence under Mailing Adress, page 1 of 21 of Instruction to Bidders "The complete original tender package, including specifications completed in full, must be included."

3.9.6 Question: On A1000, the vertical reinforcements for the foundation masonry walls are indicated as “Reinforced as per structural drawings”. If we cross-reference this with the drawings and schedule on S200, when there are two withes, only the inner one appears to be reinforced. Is this correct? Answer: Correct, inner wythe only reinforced. All cells below grade to be fully grouted. Outer wythe to be solid block. Refer details eg drawing 1, 2, 6, 8, etc… on S401 that typically shows reinforcement to inner wythe only.

3.9.7 Question: Drawing S012, Detail PC30. Please specify dimensions and locations for both angle on each side of the steel beam to support hollow core slab. Answer: We understand you are referring to details PC28, PC29, PC30. These are

Could you please clarify? Answer: For all concrete topping on pre-cast concrete slabs provide mesh reinforcing as shown on plan. If none shown on plan then none required. (applies to detail 17/S420 and all other related / similar details on S420, S421, S011 and A012)

3.9.10 Question: Should I used the block wall reif. For all the walls based on thickness of wall? Because it is very inconclusive. Answer: Vertical reinforcement for block masonry walls shall be as per Masonry Wall Schedule on S200. Requirements sometimes vary for the same wall thickness depending on the function and requirement of the particular wall. Please refer to the schedule on S200.

3.9.11 Question: Is there any reinf. For parapet or should it match the same reinf. As wall? (please refer to section 15/S420). Answer: For reinforcement to the parapet wall in 15/S420 continue the same reinforcement from the wall below, i.e. as per 15/S420 refers follow the S200 Masonry Wall Schedule or min of 15@200V with cells fully grouted. For all parapet masonry walls all cells shall be fully grouted and reinforcement shall be the minimum of that required in the S200 Masonry Wall Schedule or as otherwise noted. Also refer to S011 and S012 for typical details.

3.9.12 Question: Pier reinforcement is missing on S300. I see reinf. For Piers on drawing S401 on Section 20/S401 & 10/S401. Answer: For vertical and tie reinforcement for footing caps (i.e. for the cap schedule provided in S300) refer to typical detail CF3/S010.

3.10 Response to Bidders’ Questions – Civil


3.10.1 Question: Reference drawings - GR-1, ER-1, SS-1; The scale on the civil drawings appears to be incorrect, when scaled at 1:200, they do not line up with drawings from other disciplines, and the service conduits shown on sheet SS-1 are much shorter than the length indicated next to each one. Please confirm which drawings are at the correct scale and which should be scaled differently. Answer: Please revise the scale for drawings GR-1, ER-1, and SS-1 from “1:200” to “1:300”. This has been revised in this Addendum No. 3.

3.10.2 Question: Drawing SS-1. Please provide specifications, details and top or bottom elevation of the 20 m³ storm water retention tank shown on the Site Servicing Plan. Answer: 3mx5mx1.3m 20m3 STORAGE TANK 200mm N INV. 139.61 200mm OVERSPILL S INV. 140.56 Reg-U-Flo 8.5 SH VORTEX VALVE ORIFICE S INV. 139.56 This is your invert of the tank. +1.3m = 140.86m That’s the inside of the top of the tank.

3.11 Response to Bidders’ Questions – Mechanical 3.11.1 Question: On Mechanical drawing M310, outlets were shown to connect to a structural

beam. I did not see any spec for articulating arms or ceiling columns on the architectural so we are not quite sure how they will install these. They do mention if they are ceiling outlets so the ones below are questionable to me. We also looked at the architectural plans and they did not show anything. Please advise.Answer: Refer to architectural reflected ceiling plan drawing 1/A201 and section detail 2/A501 for the identified beam.

3.11.2 Question: The ductwork shown on dwg. M420, grid 8 to 10, G to j appears to be in a 12 ft. high ceiling space without access. Is this duct in an exposed or concealed area?Answer: Rooms WH-1003 Surgery and WH-1004 Treatment are tall spaces with clerestory windows. The ductwork in these rooms are located at the ceiling level. Please refer to the architectural reflected ceiling plans and building sections to understand these spaces.

3.11.3 Question: In Optional Price No.1 document OP-SK-1.8 under heading "Mechanical Revisions" it states that "buried plumbing services are to be installed as per plans (except for lines serving deleted areas). On drawing M200 near gridline N between gridlines 3 - 5 a 12" storm sewer is indicated. If the Optional Price No.1 is selected, the 12" storm sewer will not be able to be installed in the location indicated due to the existing Invertebrate building not being demolished. Please indicate optional location of 12" Storm sewer so that it will be able to pick up all items between gridlines A-K and 2-9. Answer: Route the proposed 12” dia. storm line around the “to remain Invertebrate House” and connect to civil service in same location.


3.11.4 Question: Please provide specifications for ME-10, RO System. Answer: Refer to attached H.H. Angus Mechanical Addendum No. 2.

3.11.5 Question: Please provide specifications for in-room Humidifiers ME-11A to ME-11G Answer: Refer to attached H.H. Angus Mechanical Addendum No. 2.

3.11.6 Question: Please provide pump schedule and specification. Answer: Refer to attached H.H. Angus Mechanical Addendum No. 2.

3.11.7 Question: They are using 09 code but code is only for healthcare facilities. Please advise. (Section 22 63 13, Clause 1.3.2.1) Answer: Refer to attached H.H. Angus Mechanical Addendum No. 2.

3.11.8 Question: On page 7 of the ductwork specification, Execution 3.1.1.1,.2 and .3 indicate that all the ductwork needs to be insulated. Since the 1st floor has a large area that is exposed without a ceiling the cost of insulating this duct is extensive. Please confirm that all this duct requires insulation. Answer: Refer to attached H.H. Angus Mechanical Addendum No. 2.

Re: Landscape clarifications and revisions and responses to RFI’s 1. The following revisions are to be incorporated in the Work prior to the award of

Contract in accordance with the requirements of the contract documents. 2. The cost of such revisions shall be included in the Tenderer's submission.

Description of Addendum

A. RESPONSE TO BIDDERS QUESTIONS

1. Question: Could you please provide the thickness of Pervious Concrete and Granular

B. The Geotechnical report makes no mention of pervious concrete. Load-bearing and Hydrogeological requirements should be determined by the Consultants.

Answer: Refer to attached LSK-1. The Pervious Concrete should be 150mm, ontop a 150mm depth of High Performance Bedding (HPB), on of a geotextile, on 200mm depth of Granular ‘B’, on top of a geotextile on ex. compacted subgrade. Drain subbase to an infiltration trench down the centre of the parking lot. This detail shall replace detail 8 on sheet L-03, Hydromedia Permeable Concrete Paving.

2. Question: The top and bottom of wall elevations given at the end of the wall near the existing road are 142.65 and 141.35 which gives a height of 1.3m but on 9/L-03, the elevation shows that wall as being 0.3m high. Could you please clarify which is correct?

Answer: Drawing L-01 contains a typo in the spot elevations. The CIP concrete wall elevations at the east end of the wall should read: top of the wall at 141.65 and bottom of the wall at 141.35. The detail is correct showing a wall height of 30cm. See attached re-issued L-01 and revision bubble.

3. Question: On drawing L-02, the upland Beaty mix for the grass, add up to 58%. Evening Primrose, Indian grass and Greenheaded Coneflower do not have percentages. Please clarify what is the percentage missing?

Answer: Evening Primrose is 15%. Greenheaded Coneflower is 10%.

addendum 1

Indian Grass is 17%

B. LANDSCAPE DRAWINGS 1. L-01 has been revised to show limits of landscape disturbance, and notes regarding

restoration of disturbed area. See attached re-issued L-01 and revision bubbles. 2. Drawing TP-1 has been added to the landscape drawing set that shows Existing Trees

to Remain and Existing Trees to be removed. Should there be any discrepancies between trees to remain or to be removed, refer to Landscape TP-1 for the most current condition. All other special notes and instructions regarding type of hoarding to be as per Arborist Plan.
