Here are
some perfect examples to show different results from good building practices
vs. details in accordance with NZBC AS1 or NZS 4306.
A good building
practice:
Post/beam
connections simply sandwiched with nailed 4x2 on each side. The connection was
built 35 years ago and showing no deformation at all.
Today if
you draw that detail and apply for a building consent, you need specific
testing to verify that this detail would meet our Building Code.
A detail in
line with NZBC AS1 and NZS 4306:
The post/beam
connections are fixed with stainless nail plates on each side. Connections are
severely deformed and twisted. By the way the details have formed at 2009.
So, as a
pre-purchase building inspector, how do we judge the above details?
It is
simple when you know the first detail has formed some 35 years ago. But what
about if same detail is formed today? Do you raise concern due to deviation
from our Acceptable Solutions/Standards or happy with that? Do you believe same
timber sandwiched post/beam connection formed today will be able to perform for
at least 35 years?
