what is code for ceiling lights of a bedroom in a half storey?
must be at least 2.1m over the lesser of the area of the room itself or 3.5m squared
what needs to be in place if the dormer wall is set back from the main wall below?

what is and what does a cricket do?
also known as a chimney saddle, a cricket is designed to divert water away from the high side of a chimney
the building code requires chimneys that are ____ mm or wider to have a cricket built behind them
750mm
the cricket has a span equal to what?
the width of the chimney
what 4 dormers are there?
shed dormer, gabled dormer, hipped dormer, eyebrow dormer
how is the slope of an octagon roof specified?
by the slope of the common rafter
what is a way to reduce congestion at the peak of an octagon roof?
by a blocking technique that will end the common rafters before they get to the peak
what is the distance of the blocking from the centre of the peak?
equal to the spacing of the common rafters resulting in the roof sheathing not getting over-spanned at the peak
what is the equation to find length of block at the peak?
spacing X Tan22.5 = opposite X 2 = length of block
what is the saw set to when cutting the blocks plumb?
22.5
what rafter is at a flatter slope?
The hip rafter
what is the unit of run for a hip compared to 12” unit of run for a common?
13”
what numbers on a framing square would you use for plumb cuts on a hip?
the unit rise and 13”

what is the plum line adjustment at the tail end for 1 1/2 stock?
5/16”
what angle would you set the circular saw too to cut that tail end?
22.5 degrees
what is another way of reducing congestion at the peak?
and octagonal post with each side cut plum to thickness of hip
what is the calculation from working point to shortening on a hip jack?
.75 / sin22.5 = 1.96” + 1 15/16”
how to find dimension for the hip jack side cut
.75 / tan22.5 = 1.811” = 1 13/16”
