Hello everyone,
I’m new here. My name is Tobias, I’m 30 years old, and I work as an electronics technician.
That’s a bit about me.
Now for my first question.
It turns out that the soil on the plot is quite poor, meaning there is groundwater at about 1 meter (3 feet) depth, and solid ground only starts at 2.2 meters (7 feet).
The architect suggested that the best approach would be to place continuous strip footings under all the load-bearing walls. So, at those positions, excavate down to 2 meters (6.5 feet) and fill with concrete and steel reinforcement.
I have a few questions regarding this:
1. Has anyone had experience with such poor soil and possibly a high groundwater table and could share some tips?
2. Does the rest of the soil within the strip footing area also need to be excavated down to 2 meters (6.5 feet) and backfilled with gravel? Or would a depth of only 0.5 to 1 meter (1.5 to 3 feet) be sufficient in those areas?
3. Is it possible to roughly estimate the cost per cubic meter (cubic yard) for this type of work?
Thank you for your help.

From 2.2 to 4.0 meters (7.2 to 13.1 feet), there is gravel, sandy, and weakly silty soil.
The architect said it would be sufficient to dig down to 2.2 meters (7.2 feet) and then install a strip foundation...

A basement is a different matter... mainly because of the cost and the groundwater level, which is at 1m (3 feet).
