ᐅ Should the terrace area be excavated during groundwork, or would that make it too deep?

Hello,
Within the next 10 days, the ground for the foundation slab is scheduled to be excavated. The contractor specializing in earthworks recommended having the area for the terrace excavated and compacted at the same time. Do you think this makes sense? I’m concerned that this might result in too deep an excavation, making the house end up too high and requiring sand to be added later.
What are your thoughts?
Kind regards

fach1werk5 Sep 2018 17:40I asked myself the same question. Two reasons were given to me, quoting the site manager:
Brick debris "rots" over time and causes driveways to become uneven. The groundworker then had to remove it again.
When building the terrace, I also asked whether we really had to remove it again since the groundworker had deliberately put it in. One of my in-laws (a construction craftsman) took a handful of it, pressed the brownish material together, and it held its shape. Then he did the same with a handful of mineral concrete, which remained crumbly. I assume he wanted to show me that one can drain water and the other cannot. We installed granite slabs on a dry bed. Probably, a concrete slab supports itself, so a certain amount of recycled concrete rubble can be left underneath. It might be different with fine-grained coverings.
Our experience is that groundworkers often want to hide things, and it is definitely not what the clients wanted to keep.
Best regards,
Gabriele
