foundations for a light weight structure
(OP)
Hello, i am designing a small structure where it is composed of 1 floor ( ground +roof). The loads are light ( spans between 4 and 5 meters).
Regarding the foundation i am hesitant between 2 scenarios:
1- found my columns at the ground floor level with removing the top 600 mm soil and compacting and flooding the bottom of the excavation.
2- found my columns on square foundations 1 meter below the ground floor level with marking that the contractor should ensure a minimum design pressure of 80kpa ( it is the pressure i am getting in scenario 2).
What do u think is the most appropriate method ?
Thanks in advance

I add one point. Flooding is a very questionable procedure for any area for structure support. More commonly water is not our friend.

I am interested in ur flooding remark. I have been told that it is a sort of ground improvement.
Thank u

If you can't get a local geotech, look for a very experienced contractor and see what he has to say. Apparently you have some idea of soil capabilities or lack thereof. In these cases sometimes just a wide footing is all that is done. Take a typical garage, the building sits on the slab over almost any ground.
