founding or piling through ground made up
founding or piling through ground made up
(OP)
hi, we have a site and on part of that site we have to place found. The contractor has starting excavating the area prior to us completing the design. The ground is made up of lots of loose bricks etc. So made ground but with lots of obstructions. I don't want to found on it, they say they may have trouble piling through it. Its a bit of a catch 22. Its a lightly loaded structure, so we may get away with ground bearing. Any other ideas out there.

Surely they can excavate through the brick and replace with engineered fill.
Is this an isolated area that wasn't picked up during the soil sampling or does it cover the entire site?

I don't believe loose bricks will hamper the drilling operation but large chunks of concrete will. I had the same problem a couple of years ago in a very deep fill. A small percentage of piles had to be re-located because they ran into either boulders or concrete chunks at a depth of about 3m. The piles were 400 diameter x 10m long friction piles.
It was not a major problem in my case, but if in doubt you might want to try a few test holes before committing to a particular design.
