Comment: Finishing/Sealing Fibre Cement Products - says "Vertical joints shall be caulked in accordance with manufacturers instructions" I believe this should be changed to say "caulked or flashed" Hardie for example does not recommend caulking vertical butt joints and instead recommends flashing behind the joints Technical Bulletin #9: Butt Joint & Horizontal Lap Treatment https://www.jameshardiepros.com/getattachment/ba7585b2-9a27-4aa4-a017-ea6a4acdbfa9/9-joint-flashing.pdf

Comment: The note on the image tells the viewer to chalk a line 150mm back from floor edge. I believe this should read 140mm back, so the ext. sheathing will be flush with the floor frame ext. sheathing. Students are taught that the foundation dimensions shown on the plan are the wall frame dimensions, and sheathing is applied outside of that.

Comment: “As with the air barriers, care must be taken to ensure that the vapour barrier is a continuous seal throughout the building” The word seal should be removed, because vapour barriers do not need to be sealed in the same manner air barriers do. Probably a result of confusion between Air/Vapour barriers because we use poly for both. But, in a rigid air barrier, such as airtight drywall approach (ADA), a poly vapour barrier only needs to be lapped not sealed with tape or acoustical seal (pp 28 020204h Insulation and Air Barriers)

Comment: Re: Figure 67 and NOTE box above. Graphic is labelled incorrectly. Intersection of theoretical line at ridge should be labeled "Total rise working point" The point above may then be labeled "total rise working point + WAP" or don't label at all. Note box should read something like "total rise of roof is the intersection of theoretical working lines at ridge."

Comment: When milling a door for a latchbolt, the module describes the order of operations as : latchbolt hole drilled first, and then the cylinder hole is drilled. This should be reversed because if the cylinder is drilled first, then the carpenter knows when to stop while drilling for the latchbolt. Some cylinder brands even require drilling a small distance beyond the cylinder for the latch bolt. It would be difficult to achieve this accuracy if drilling for the latch first.

Comment: In the first sentence, it states that the National Building Code sets a minimum unit run as 210mm for private stairs. In the 2015 National Building Code in Table 9.8.4.2. it states a minimum unit run for private stairs as 255 mm. My question is, in the Apprenticeship exam for Level 2 carpentry, which figure is used? Would it be possible in the future, to specify which version of the NBC is being used in the modules because some of the information seems to have been updated while other has not which is cause for confusion. Thank you.

Comment: "Answer to Practice L Stair Calculations" starts out with correct unit of rise being at 181.9mm in step one. In the equation for step 2, it has been calculated using 181.7 mm which is incorrect and the following steps need to be recalculated as this error affects most of the answers for the remainder of the math problem.

Comment: In the Ceiling Framing Calculation module on the page 9, step 8 for Calculating ceiling framing material for Hip Roofs. The method of calculating material for stub joist seems flawed. Stub joist material should be calculated similar to stakes and cleats in first period where you first determine how many stub joist you can get from each piece of material rather than a total length of stub material required. This error in calculation can be seen in question 2 of the self-test on page 26. 30 stub joist are required and the answer is 7 pieces of 12 foot material. Being the stub joist are 32" long, you can only get 4 joist per 12 foot piece of material and the answer should be 8.
