Old Business:
7.1
Method for 9.36 Trade-Off calculations
Craig Skinner
Carried over from Dec.9 2015, Jan. 13 2016, Feb. 10 2016, Apr. 9 2016
City of Burnaby is actively using the Trade off Calculation in the field for every 1 of 8 stud
spaces may be reduced to R10 without requiring the calculations to be provided based on
the verbal confirmations of Zach from the policy branch in conversations and in his
presentations.
Section 9.36.2.11 Permits Trade-offs for ducts, pipes etc.
Without an official document that says this practice does not contravene the code most
other municipalities are requiring the calculations to be provided before accepting the
solution.
7.2
3.2.1.1. Building Height Amendment
James Hook
From March meeting:
An apparent wording change makes it clearer and more restrictive. This is not really a
change as the previous wording said the same thing but in a different format.
James will ask NBC National to clarify.
Waiting For Reply. – Carry.
8.0 New Business:
8.1
Blue sheathing tape
Belinda Moen
Product inquiry for Blue Vapour barrier specific tape.
As per discussion lapped and structurally supported seal will be effective with either the red
or blue tape. The BC Building code does not dictate the material to be used.
8.2
Limiting distance Squared / Response time
Nelson Wall
Where the fire department response time requires the applicant to use half the limiting
distance value for Glazed Openings, can you use the limiting distance squared method for
glazed openings as noted in “c” below?
9.10.15.3. Limiting Distance and Fire Department Response
If you must use half the limiting distance, where the code references a limiting distance, the
value which pertains to the SFD you are reviewing must be half of the actual limiting
distance when applying limiting distance requirements to each subsection?
Sentence 9.10.15.4. Glazed Openings in Exposing Building Face
1) Except as provided in Sentence (6) (this is for accessory buildings), the maximum
area of glazed openings in an exposing building face shall be
a) conform to Table 9.10.15.4.,
b) conform to Subsection 3.2.3., or
c) where the limiting distance is not less than 1.2m be equal to or less than the limiting
distance squared
8.2 continued:
The reduction would be applied before (c). If less than 1.2m zero openings would be
permitted.
8.3
Open risers and 100 mm safety spacing
Nelson Wall
Open risers in a SFD are allowed, however the construction of stairs with an opening
greater than 100mm between treads has been noted in the field. Do other jurisdictions
“invoke” the guard requirement of no openings greater than100mm sphere allowed because
the elevation of the stairs is greater than 600mm above the finished floor?
All agreed; Guards are regulated; risers in open stairs are not. The triangular section over
stairs is part of the guard and must comply.
Interpretations attached.
8.4. Pool Fencing
Nelson Wall
Question was asked if the pool itself needs to be enclosed with a fence or if fencing the
property would suffice.
As per discussion each municipality’s bylaw would prevail in regulating the fencing around
a pool. Majority would accept either method as compliant.
8.5
Rigid Vinyl Cladding
Brenda Moen
Product evaluation of “Sagiwall panel”
Would everyone accept this product in circumstances where LD is less than 1.2 combustible
cladding + 45 min FRR is required?
9.10.15.5. (3) says that cladding tested to the standard “fire test of Exterior Wall
assemblies” are found to comply.
The data included in the test report suggested that the material meets all of the criteria and
testing for the appropriate CAN standards. However, the test report was in its draft form and
not yet issued. All would accept the product once the test report was no longer a draft.
8.6
Limiting distance < 2M 9.10.15.4.(3)(4)
See Drawing below:
Spacing would be required once the 50% Maximum is reached.
8.6 Continued:
Trevor Welsh
8.7
Demolition Permits SFD ~ Geotechnical review
Trevor Welsh
On a sloped and potentially hazardous site would a Geotechnical Engineer be required?
Most agree that if any uncomfortableness exists they would ask for a Geotechnical Schedule
“B” or signed sealed letter.
8.8
Farm Buildings over 4800 m2
Henry Kuipers
Over 4800 sq meters would require a firewall. Would an alternate solution be acceptable for
a non-combustible proposal?
Most would look at an alternate solution prepared by a professional.
8.9
Built in man door/ Garage door
Richard Dohmeier
Richard asked about egress from a parkade where cages divide parking areas
within the parking garage.
Segregated cages require a means of egress that do not rely on the overhead door.
