REVISED CLOSING:
The RFQ closing date is being extended to Friday, November 20, 2009.
Standards and Specification Clarification:
We require the following clarifications
Q1:
The correct location of the plumbing rough in in the multi purpose room. Drawing A2 indicates the
rough in on the east wall, while drawing M2 calls for it on the West.
A1:
Correct location for plumbing rough in at the wall between the multi-purpose room and the
storage room, as shown on drawing A2.
Q2:
The correct framing details for the wall between the multi-purpose room and the storage room.
Drawing A2 calls for 2X4 studs at 16” o/c while A8 calls for 2X4 studs at 12” o/c.
A2:
Correct spacing is 12” o/c.
Q3:
The correct bolt size for the change room bench supports. Drawing A4 detail 1 calls for a 5” bolt
with a 6” penetration (which is not possible), yet the detail calls for 4”. Is the 5” bolt with 4”
penetration correct, or is it to be a 7” bolt with 6” penetration.
A3:
Precast supplier will provide inserts. See comments after Answer A16 which indicates in
more detail what Precast Supplier will provide.
Q4:
Coat hooks and supports, as indicated on A4,
A4:
Description of sizes is referred to in the notes on Drawing A4.
Q5:
The crezon board is currently only shown to be filled and sanded in the multi-purpose room. Is this
to be applied to all rooms?
A5:
All ceilings to have Crezon boards filled and sanded, and drawing currently shows ceilings
at change rooms and washrooms are painted.
1
Q6:
Is crezon board to be installed in the storage room?
A6:
Yes
Q7:
Door sizing. Addendum 1 still leaves it unclear as to which takes precedence. Drawings call for a
6’8” door height, while the specifications call for a 7’0” door height.
A7:
Make all man doors 6’-8” high.
Q8:
We request to change the coating on the steel brackets for the bench supports, as well as the
coat hooks, from “powder coating” to “Epoxy Paint”.
A8:
Epoxy Paint is acceptable.
At the site meeting, it was indicated that the block walls will be changed to pre-cast. We require
the addendum for the change from block wall to pre-cast panels with the following
Q9:
Maximum panel weights.
A9:
Not sure why this is relevant, Precast Supplier is installing the panels. Interior walls will be
75 psf, exterior walls will be approximately 85 psf.
Q10:
Will coring be required now for the plumbing and electrical?
Q10:
Some coring may be required for plumbing, will provide block outs if they can be
determined prior to pouring precast panels. If block outs are provided, will have to grout in
as required. See the comments after Answer A16, indicates Electrical conduits and boxes
that will be provided by Precast Supplier. Note conduits will stub up to top of Precast
panels.
Q11:
Will the top plate be preinstalled for the installation of the roof trusses.
A11:
No, inserts will be provided at top of Precast panel in order to bolt top wood plate to top of
precast panels.
Q12:
Footing/slab/panel connection detail.
A12:
Precast manufacturer will provide dowel layout, GC will have to supply and install approx.
24 vertical rebar projecting 15” out of the footings, waiting for more details from Precast
manufacturer.
Q13:
S1 shows 7 door openings on the West side. A2 shows 8.
A13:
Drawing A2 is correct.
Q14:
S1 shows 2 door openings on interior wall at South end. A2 shows 2.
A14:
Drawing A2 is correct.
Q15:
Foundation walls have no Horizontal wall reinforcing shown (2 Bot. of footing and 2 Top of wall
and nothing between).
A15:
Since we are now going with Precast walls, there will be no foundation wall, only Footing.
2
Q16:
15M dowels @ 1200 alternating every 3rd with 20M should read 15M @ 400 alternating every 3rd
@ 1200 (see below)
A16:
Not relevant, since walls are now going to be precast.
Precast Panels, that are going to replace all the Block walls.
The following is scope of work that will be provided by the Precast Supplier:
1)
Exterior wall panels at approx. 11’-6” (most likely will be closer to 11’) high, with "striated
broom" exterior finish (and smooth on the interior). (11'-6” wide panels are the maximum width
we can ship, without using a pilot car.) Overall insulation value of R20. You may need to tweek
the thickness of your footing a bit to get the required elevation for your intended "top of wall"
elevation. The panels along the two long walls would be 21.4' long. The exterior corners would
be mitred.
2)
The interior walls would be 6" solid, with an overall height of 11'-2" (most likely will be 10’-6”
high). These 5 walls would span across the building and be supported on the inner face of
the exterior walls (by utilizing a weldplate and a supporting ledger angle) at the lower corners.
You would not need a specific footing under these panels. You would run reinforcement for your
floor slabs through notches in the lower edge of our panels and have a thickened floor slab
beneath the panel. Top edge of the interior panels will be at same elevation as top edge of
exterior panels. Bottom of these panels will be approx 6” below typical slab elevation at exterior
doors. **Note that exterior footings will have to be increased in size to support additional weight of
3
these panels, but revised Structural drawings are not available at this time. Allow in your
quotation for the footing size and quantity as shown on Structural Drawing, and if quantity of
concrete of final Structural drawings exceeds what is currently specified, this will be treated as
extra to your contract.
3)
Precast panels at the interior "entry" (acting as "pass-thru's) to the changerooms, that go down to
top of footing elevation... you would need a small strip footing here for us to set those panels into
final position. Have also allowed for precast panel at sides of urinal, allow for footings below
these panels.
4)
All panels installed complete with:
a)
b)
5)
Grouting of all underside bearing surfaces. Top of footing to be installed to tolerance of
plus or minus 3/16” of required elevation.
Panel/panel welding (and all connections are non-visible after caulking is installed).Interior
and exterior caulking with a polyurethane (paintable).
c)
Temporary pipe bracing (until roof diaphragm is established).
d)
Our sealed shop drawings and Engineering seal
Miscellaneous Items", including the following:
a)
Ferrule inserts (usually 5/8" dia.) cast into the top of our panels at 2-1/2" o/c (Structural
Engineer will establish prior to fabrication) for bolting of the top bearing plate (i.e. General
contractor to supply and install 2” x 8”), to our panels.
b)
Man door frames cast into our panels... frames to be supplied, by Others. (Due to
timing, most likely General Contractor will have install these to Rough opening
provided by Precast manufacturer, and should allow for in General Contractor’s
budget)
c)
Rough Opening for roll-up door at the Storage Room.
d)
Inserts (or notches for the 6" solid panels) at 3' o/c for tieing the wall panels to the floor
slab (using threaded dowels). (Dowels to be supplied by General Contractor.)
e)
"Electrical embedments" for:
- 3 door opener buttons and conduit.
- two recessed hand dryers.
- 12 exterior lights.
- 2 exit signs
- 7 wall plug boxes and conduits at Multi-purpose room
- 2 wall boxes and conduits for Thermostats in Changerooms
f)
Thickened concrete interior wythe in region of H/C grab bar, for good anchorage of
fasteners.
g)
Embedded inserts for the benches and coat hooks, so site fasteners are accommodated.
The inserts for the benches would be a galvanized-style unit, so that "plated" N/C
fasteners can be threaded directly into the insert.
Comments:
1) Not applicable
2) Panels would be secured to the footing via a dowel bar/grout sleeve connections. This means that the
footing contractor would probably need to install approximately 24 vertical rebars projecting 15" out of the
footing. (We would provide a dowel bar layout, with our shop drawings.)
3) Delivery: approx 1-1/2 week to complete shop drawings, and 2 weeks for precasting. We
would complete installtion in 2 working days.
4) Panel Finishes:
Pricing is based on our standard "striated broom" finish.

Q17:
Concrete specification.
A17:
Lafarge has reviewed the concrete specification and has the following qualification/clarification
request(s).
Mix Design Submittals Lafarge will submit a Mix Submittal Sheet (MSS) indicating whether a
constituent is present or not in each mix design. The MSS will also indicate CSA concrete
classification, air content and category, mix slump, and maximum water to cementitious ratio.
O.K.
Concrete Properties
The air content for the concrete is specified at 5%+/-1%. Lafarge requests that air content for
concrete to be changed to an air content of 5.5% +/- 1.5% as per CSA definition of C4 or F2
exposure class concrete. The slump for the concrete is specified at 50mm +- 13mm. Lafarge
requests that concrete specified at50mm +-13mm to be changed to 80 +- 20mm. The concrete
mix is designed to perform at 80mm slump. However, Lafarge can deliver 60mm slump if 60mm
slump is requested when ordering through dispatch. Quotation is based on the acceptance of this
request.
80 mm slump is ‘acceptable’
Q18:
Exterior Blocks Walls:
- the elevation drawings show both a standard concrete block and a split-faced concrete block.
Is it one or the other? Or is there course of bands of split-faced blocks and standard block? If so
what's the pattern?
A18:
Not relevant, since Precast walls will replace all block walls.
Q19:
States that the Contractor will not be required to provide: services, excavation and backfill,
landscape and asphalt. Yet the Schedule B Appendix 2 Supplementary Specifications appears to
indicate that the Contractor shall provide site services, testing of excavation and backfilling. We
intend to provide our quotation as per the Special Provisions unless advised otherwise. This
would include that the backfilling to the underside of the slab on grade is not required to be done
by the Contractor.
A19:
City has provided Excavation and backfill to underside of footing. General Contractor (i.e.
GC) to proof roll and call for Geotechnical inspection (i.e. initial inspection paid for by City)
prior to installing Footings. GC to supply and install balance of backfill material to
underside of building slabs and within 6" of finished grade at exterior of building (assume
backfill at exterior of building to 6" below top of slab at exterior door locations) GC Should
review site conditions prior to providing quotation, and review Geotechnical report.
Q20:
It states that the City of Surrey shall install the site hoarding and will be maintained by the
Contractor. Yet other documents appear to indicate that the hoarding be provided by the
Contractor. We do not intend to provide this hoarding.
A20:
As per site meeting, City has installed and will pay for fencing, GC to maintain fencing
while they are responsible for the jobsite.
Q21:
Permits and Fees; It appears clear however other documents indicate that the Contractor shall
include for any deposits for the site services but yet the site services are not within our scope of
work. Also the extent of inspection costs which the Contractor shall include for is unclear. What
specifically is the Contractor to include for? Example; soils testing, concrete testing, painting
inspections, roofing inspections.
A21:
City pays for Building Permit and permits related to underground services that they have
provided. GC pays for all trade permits not paid as part of Building Permit. City will pay
for initial inspection fees. Should re-inspection be required, the cost of re-inspection will
be paid by the GC.

Q22:
It states that the City shall supply the plumbing fixtures, yet other documents indicated some
fixtures supplied by the plumbing contractor. We will include that the City will provide the
plumbing fixtures as stated which includes the faucets which are plumbing fixtures, unless advised
otherwise.
A22:
The City to provide list of Fixtures that City is going to order. This information is currently
unavailable. The City will continue its best efforts to obtain this information and release it
in a future addendum.
Schedule B – Appendix 2; Supplementary Specifications.
Q23:
It states that the roofing shall conform to RCABC but yet it does not state that we are to include for
a RCABC warranty. As you probably know a RCABC warranty can be pricy and some clients do
not wish to have this warranty. Are the Contractors to include for a RCABC warranty?
A23:
RCABC Warranty is not required. Roofing contractor is to provide written 5 year warranty
on roofing, flashing and snow Guards.
Q24:
It states that “Field Engineering is not to allowed”. What does this mean?
A24:
Not sure where this is specified, all engineering services will be provided by City, unless
specifically specified otherwise.
Q25:
It implies that the Contractor shall perform a degree of site preparation, yet the Contractor is not
required to perform the excavation and backfill. We do not intend to include for any site
preparation unless advised otherwise.
A25:
Site preparation has been provided by City to underside offootings. See Answer A19.
Q26:
It states that the Contractor shall pay for the meter and connections fees, yet in Appendix 1 the
Contractor is not responsible for anything beyond 4’-0” from the building. We do not intend to
include for any connection fees, inspections or meter costs for work beyond 4’-0” from the building
unless advised otherwise.
A26:
City will pay for meter and connection fees
Q27:
Please note that the Division 16 is headed as Mechanical. We realize that the intent is Electrical.
A27:
Division 16 headings should read “Electrical”.
Q28:
Why is it stated that the Plumbing Contractor shall design the domestic water, sanitary and storm
systems when they are defined on the drawings. We assume this is an oversight and do not
intend to include for design work unless advised otherwise.
A28:
Mechanical engineer will provide design of water, sanitary and storm systems.
Q29:
Which wiring connection box is the electrical contractor expected to design?
A29:
See Electrical drawings, these will take precedence
Q30:
What type of Heavy Duty Galvanized Roll up Door shall we include for?
A30:
See Addedum # 1 for details.
Q31:
On drawings M-2 and M-3 it states to provide separate pricing. Where and how do you wish this
identified on the tender document?
A31:
Firstly, this is NOT a tender document. Please do NOT identify it as such. Note, perimeter
drains are not required. Add your separate pricing in Schedule C – Section 2.
Q32:
A cross section of the exterior wall states “glass blocks” yet no glass blocks are shown on the
elevations. Are there glass blocks and if so where?
A32:
No glass blocks are required, obsolete note on Structural Drawing.

Q33:
Details required for the snow guards.
A33:
Roofer to size appropriately, they can look at Roof that was provided at Tom Binnie Field
House Building in Whalley, adjacent to BC Lions training facility.
Q34:
We assume that the ceiling design meets the design requirements for the fire rated ceiling.
Please advise if this is not the case.
