Observe and Report
The course improves the hom inspector's.... (I think it should be home :) )
Common Structural terms
**Slope *definition states: . It's typically reported as the number of inches of rise for every foot of run, should that be inches of rise for every inch of run?
In the examination we are asked what is the most common foundation type. The answer is Slab-on-grade, but this needs to be better queries as the most-common in the U.S. In Canada it is rare to find slab-on-grade for residential homes. Most have full basements, with a lesser amount of Crawl Spaces and very few slab-on-grade which is normally reserved for commercial properties.
Crawl Space Construction
**The diagram indicates grade heights of 24" below bottom of floor joists and 18" below the beams, but the wording says the minimum should be 18" and 12" respectively. I'm not sure the exam matches the wording, and distinguishes between minimum heights and "some code heights".
The wording talks about roofing trusses arching upwards, and it not being a structural issue, but the picture seems to show a wall drop on a floor?? Confusing to say the least. :)
In the Inspecting a Deck Illustrated attachment (yes I did read it all) in the "Pick test" paragraph it says "The inspector should first try the pick test in an area where the wood is known to be sound to deterimine a "control".
*Later in the section about Ledger boards, and Aluminum flashing it says *"Contact with pressure-treated wood or galvinized fasteners can lead to rapid corrosion of aluminum."
That's all I picked up on this one, although I did notice on John McKeena's excellent PDF Introduction to IR Thermography he mentioned that "Viewing from different Angels can effect emissivity" I don't employ any Angels, but I am married to one, does that count? :)
Also, in the course it might be worth adding the Parge coating cracks or crumbling can also be caused by poor building practices where the Parge coat is not sticky enough. (i.e. they use mortar mix instead of Portland/Sand mix) or it is applied too thickly and it drops off after it dries.
Other than that, I've found all the information supplied to be exemplary, useful, and given the amount of work that's gone into this library of relevant and informational service I've found precious few errors. (Aside from the U.S. English vs. Canadian English for which you are entirely forgiven :) )
I look forward to completing the rest of the courses.
