On Friday, I will be teaching detailing, the problem is, were to begin, there is so much to learn, the law, materials, sequence of operations, the foibles of CAD
, what to show, and how, the use of colour, what works and what does not, Agrement certification, the list goes on.
So the first lecture I will give is to look at the building regs, the makeup, why they are there, a little history, the role of the approve documents, and above all, whats in them, plus whats not in them, ie some of the tables, they will need, span tables and the like, its will take some time, but I want to get it clear.
The next item, and one I think should receive more attention, is whats worked already, and what has not, there is no web site to show failures, but existing buildings are there, waiting for you to walk past them and take note of failures, and success.
I used to do a lot of testing of insulation, putting boards on exposed roofs to see what happened, bonding them to other materials and testing them in freeze thaw
machines to test the bond and material strength
, but real life is already doing it, and you only have to walk down a street to see it, and in some cases, the tests have been ongoing for 200 or more years.
So I will be taking my new 1st year students on a walk, to show them materials in use, and asking them to note whats good and bad, plus how the construction was put together. I expect them to take a lot of notes, both n their day books, the mobile phone all seem to have, and I want them to get to know Evernote.
