RE: Cat5 related regulations

["Dean Barrett" <dean@xxxxxxx>]

Drilling Joists is common practice/only solution in new house build, as is
notching tops for pipes. New wood technology now means most smaller (upto 5
bed) properties are built with laminated joists that come pre cut, full of
holes that just require knocking out, you are also able to drill holes up
to
4" diameter :)

If you are talking about trusses - you never drill them !!

Joist drilling should be avoided entirely. My builder put 2" timber on
top
of all the joists so the
2" stuff will be cut for pipes and cable, leaving the joists
untouched. It
also gives 2" to get over
the top of the steel joists (of which there are quite a lot).

Crossing mains cable should be minimal - and certainly only at 90 degrees.

I was just concerned about what the building inspector might have to say
when he sees my NZ.

Is this a non-issue?
