Key word : Resistance to Forced Entry
9.7.5.2. (7) Except as provided in Sentence 2, strike plates for deadbolts described in Sentence (4) shall be

If your tread stock is
(29 mm) thick and the lower finished floor is 3/4” (19 mm) thick, what
would be the drop of the stinger if it were resting on the subfloor?
3/8” 10 mm)
To calculate the amount you drop your stinger, take your tread thickness and subtract the thickness of your lower finished floor: 1 1/8" Imperial: 1 1/8" - 3/4" = 3/8" Metric: 29 mm - 19 mm = 10 mm

Key word:
9.8.2.2. Height over Stairs
The clear height of stairways shall be measured vertically, over the clear width of the stairway, from a
straight line tangent to the tread and landing nosing to the
lowest point above, and shall not be less than:
(i) 1950 mm for stairs serving a single dwelling unit
(ii) 2050 mm for stairs not serving a single dwelling unit.
How far beyond the top and bottom of a staiway shall a handrail extend hoizontally?
300 mm
Key words: handrails, temination of
9.8.7.3. Temination of Handrails
1 Handrails shall be teminated in a manner that will not obstuct pedestian travel or create a hazard.

What is the distance from the bottom of the door to the centre of the
centre hinge given the following information:
Door height=
6’8” (2,032 mm)
Hinge height=
3 1/2” (89 mm)
Hinge location=
7” and 11” (180 mm and 280 mm)
42” (1,066 mm)
First, take the overall height of your door and subtract the distance from the top of the door to the
bottom of the upper hinge along with the distance from the bottom of the door to the top of the lower
hinge to find the location of the centre of your middle hinge:
Distance from top of door to bottom of upper hinge = x = 7" + 3 1/2" = 10 1/2" Distance from bottom of door to top of lower door hinge = y = 11" + 3 1/2" = 14 1/2" Space between upper and lower hinges = 80" - 10.5"(x) - 14.5"(y) = 55" Centre line distance from hinges = 55" ÷ 2 = 27.5"
Next, add the centre line distance from hinges to the distance from the bottom of the door to the top of
the lower hinge to get the centreline measurement of your middle hinge:
Location of middle hinge
= centerline distance from hinges + y
= 27.5” + 14.5” = 42”
Tom tim a window measuing 2’ X 4’ with mitred coners, what is the most efficient use of
tim?
2 pieces @ 8’
The overall peimeter of your window is:
2’ + 4’ + 2’ + 4’ = 12’
Therefore options C and D will leave you shot of mateial
Option B will leave you with more excess mateial (waste) than you need
What would the tread run be for a stair with 17 risers and a total un of 13’ - 10” (4,216 mm)
103/8”
264 mm)
# of treads = # of isers - 1 = 17 - 1 = 16 treads Impeial: 12inches/foot) total un = 13' X \+ 10" = 156" + 10" = 166" 10.375inches/ trea 103 /8 inches/tread tread un = total un ÷ # of treads o166" ÷ 16 treads o do Metic: tread un = total un ÷ # of treads = 4,216 mm ÷ 16 treads 263.5mm /tread 264mm /tread = ˜
Which of these windows does NOT have a hinged sash?
Horizontal slider
What is the maximum vertical height a flight of stairs can travel without a landing?
3.7 M
Key words: Stairs, Maximum height of
9.8.3.3. Maximum Height of Stairs
1 The vetical height between any landings shall not
exceed 3.7 m.
What is the total rise of a stairway when the framing members have the following dimensions?
• single bottom plate and double top plate.
•1 5/8” (41 mm ) each plate member
• stud length
92 5/8” (2,353 mm)
• joist depth (top floor),
11 3/8” (289 mm)
- subfloor (upper floor), 5/8” (16 mm) plywood.
- finish floor (upper floor), 3/4” (19 mm) tongue and groove oak.
- finish floor (lower floor), 1/8” (3 mm) vinyl tile.
- subfloor (lower floor), 5/8” (16 mm) plywood.
110 1/8”
(2,797 mm)
Total rise = 3X plate thickness) + stud length + joist depth + upper subfloor
thickness + top finished floor thickness - bottom floor thickness
Impeial:
First, convet your measurements (except your lower subfloor which isn’t) into
decimal inches:
15/8=
plate thickness =
1.625”
925/8”
stud length =
= 92.625”
113/8”
joist depth =
= 11.375”
upper subfloor thickness = 5/8” = 0.625”
upper finished floor thickness = 3/4” = 0.75”
lower finished floor thickness = 1/8” = 0.125”
Next, use the fomula above to calculate your total ise:
Total ise o3 X 1.625”) q92.625” q11.375” q0.625” q0.75” - 0.125”
1101/8”
= 4.875” + 105.375” - 0.125” = 110.125”=
Where is the headroom for a flight of stairs measured?
The distance from the line of flight to any obstuction overhead measured at 90° to the line of
flight
The following diagram shows a 15’ - 10” wall with five 20” X 40”
windows evenly spaced. What is the on centre spacing of the
windows from left to ight
C
25”, 35”, 35”, 35”, 35”, 25”
First, subtract the width of your five windows from the overall wall
length and divide the remainder by the number of spaces 6
wall length = 15’510” = 190”
total window width = 5 X 20” = 100”
space between windows =
= 90” ÷ 6 = 15”
because its asking for the centre to centre measurements, your
measurements are calculated as follows:
1st
= 1 space + (window width ÷ 2 = 15” + 20” ÷ 2 = 15” + 10”
= 25”
2nd
= 1 space + 1 window width 1/2 on each side) = 15” + 20”
= 35”
3rd
= 1 space + 1 window width 1/2 on each side) = 15” + 20”
= 35”
4th
= 1 space + 1 window width 1/2 on each side) = 15” + 20”
= 35”
5th
= 1 space + 1 window width 1/2 on each side) = 15” + 20”
= 35”
6th
= 1 space + (window width ÷ 2 = 15” + 20” ÷ 2 = 15” + 10”
= 25”

Once you have prepared your door by laying out and motising/boing your
hinge and knob locations, you must:
- install hinges to hang the door,
- install the latch through its bore hole,
- install the knob through the latch and secure to door with bolts/cover plates
- install stike at proper height relative to the latch
