This can't be right!? Wireing under sub-floor

[rubrage]

Cheers guys, I just wanted to lay some lovely wood flooring an I have uncovered a horror story!

You are welcome.

Yes, the texture on my screen confused me lol.
Thatis what is will be.

So instead of going through the RSJ they went over it, the cables are sitting on top of the RSJ and Joist beside it sandwiched by the subfloor and 4 screws. Genius! Just left a message with the builder.

Sorry to say, but no wonder it creaks, between the cables and the deep notching shown in that last pic ...

I wonder how many electricians go around with a mag drill on the van and know the calculations to be able to drill an RSJ

It is a RSJ a lot of new builds 2/3 beds this was installed at top of stairs sat on.

That is why I asked if it was at the stair head . I could not make the texture out for the sun lol.

Would you prefer it if they'd drilled a hole through the RSJ and weakened it?

Drill through the centre of the Web and it will not affect its strength at all.

If you're qualified and insured to make that call then that's great, but I think I'll stick to getting something in writing from a structural engineer before I go ahead and drill an RSJ.

There must have been another route. Or wireless interlink is acceptable to lbc and regs. Find out who is their governing body and complain to them if you don't get anywhere from going direct to the electrician/builder.
