We recently had our slab done. Looked OK, neat, as it should be. Up to frame stage now, and this is where it gets interesting... have just noticed that the frames are done according to measurements, which expose an error in the slab. One of the corners has been cut short, so we're missing a sizeable portion of what should be one big slab. This is a significant corner, as two walls will be resting on that one corner - a corner where the frame is now hanging in the air and there's nothing solid underneath it. We've already paid for the slab, too!
My main question and concern is whether the builder can fix this error (or so it should be fixed, as the bricks on the outer wall can't be done properly, unless they're resting on something solid), and more importantly - how they'll approach the problem. My guess is they'll "fix" it by using the cheapest and fastest possible option (whatever that may be), compromising the foundation of that part of the house. In my anger and frustration I keep thinking we should refuse to pay for the frame until this problem is fixed, but don't know how realistic I am with those thoughts... and whether it's doable at all.
The supervisor is meant to be visiting the site at every stage, supposedly checking that everything's going well. Obviously he either hasn't noticed this (yet that's his job!) or he hasn't got the balls to ring us and admit an error's been made (the most probable scenario), suggesting ways how this can be fixed, and calmly reassuring us it'll all be fine.
Does someone have experience with this sort of a problem, and what can be done/said to fix it, without too much fanfare???
