FRAMING OVER HANGING SLAB ?

All i'm after a bit of advice here.

Our house is at fixing stage so roofs on , sparkies been, and the brick just started. However the certifier has halted works as an internal load bearing wall frame over hangs the slab by about 15mm . An he wants an engineers report on it.

The garage slab is lower than the actual floor slab , when the framing was put up the framing ran true at the front of the house but over hangs by about 15mm at the rear. It's a 90mm frame.

The builder has packed the "gap" with timber as has dynabolted horizontally into the floor slab to support the frame. The actual frame is fixed to the slab not the packing timber.

Our supervisor assures us this is normal as the slab pour is never that accurate and the certifer is over reacting . A report is being done but i'm wondering whether i should get an independant assesment done for piece of mind ?

What if the down the track this becomes an issue ?

Cheers

Hi Marshy,

We had a similar issue for our garage, the frame hung over the slab. I didn't think much of it, however a few days later a concreter had been and had placed more concrete under the frame so there was no frame over hanging.

Hope this helps.

The 'Guide to Standards & Tolerances' allows for a max. of 10 mm overhang.
