qa (safe bearing capacity) in geophysical report

Hello, Today, they only wanted a geophysical study for a place to be held in the district. And I started to read and examine the results from the geophysics study. Since it is my 8th month in the profession, I am learning many things just now. My question to you, my engineer brothers, would be: There is a qa (safe bearing capacity) value in the geophysics report, this is the qt (soil bearing capacity) where we enter the soil properties of the street. I don't think it's the same as ). What is the logic of this? How can I find the qt value from the qa value with a calculation method? Or can I substitute the safe bearing capacity (qa) directly for the qt value? At the same time, the geophysical report does not include the bed coefficient and soil unit weight. idecade how do I enter these values? The first layer is 2.70 m2 and qa=0.99 kg/cm2 The second layer is qa=1.34 kg/cm2 When I convert them directly to t/m2, the value is very low, like 9.893 t/m2
 
We had the same situation in one of our projects. I asked the soil surveyors for the qt value or to confirm if it was qa=qt. Some ground surveyors have not yet gotten used to the new regulation. Unfortunately, some uneconomical projects will be produced in this process. As a result, the necessary data in the calculation should come from the floor study. At least qt.
 
Demand whatever values you need. Do not calculate anything yourself. The values you need should be in the geotechnical report section of the soil survey. The geotechnical report is prepared by a civil engineer specialized in geotechnical. "Your signature is required for the ground survey, it will be signed by a statician" etc. they may say. Do not take responsibility by signing reports and projects that you did not do or do not know about. Both for yourself and for the reputation of the profession.
