Any one can tell me how i can calculate soil bearing capacity at 2m level from below provided data however in soil test report soil bearing capacity is recommended 0.75kg/cm^2 at 1m depth for shallow foundations but i want to construct my footing below the underground water table level at 2m. (underground water table level is below 1m from natural level).
I guess the bearing capacity will be more at 2m level for footing (footing might be isolated or might be raft).

Soil conditions on the basis of existing ground elevation investigation by Boring and cone penetration data is as follows :
0.00 - 2.00 m : A clay, a medium stiff consistency
to stiff, brown color with cone penetration resistance, qc = 10-20 kg / cm2.
While the borlog NSPT value = 7-9 blows / 30 cm penetration,
2.00 - 6.00 m : Is sand, dense medium brown color
with the value NSPT = 18-32 blows / 30 cm penetration and qc = 80-250 kg / cm
6.00 - 16.00 m : A layer of sand, dense brown color with a value NSPT
= 34-47 blows / 30 cm penetration
16.00 – drill end : A layer of coarse sand, very dense brown
with the value NSPT> 60 blows / 30 cm
penetration From the cone penetration work, hard layer (quite hard layer), the layer with value (qc) cone penetration ≥ 250 kg / cm² encountered at depth as follows:
S1 in depth - 3.40 m from the existing ground surface elevation
S2 in depth - 3.20 m from the existing ground surface elevation
S3 in depth - 2.80 m from the existing ground surface elevation
S4 in depth - 2.40 m from the existing ground surface elevation
I guess the bearing capacity will be more at 2m level for footing (footing might be isolated or might be raft).
