RE: CPT analysis
You're best to either have a CPT expert do it or develop spreadsheets yourself from published research papers.
I am not personally familiar with what publications are readily available. Yet another reason to get an expert involved.

Qt: Is the tip resistance corrected for pore water pressure.
and Nk will vary between something like 11 to 18 depending upon the soil conditions.
However, in sands it gets complicated, its based upon the relative density of soils. I am still trying to figure that out. There is a software called CPTINT published by University of British Columbia. Can't seem to find it anywhere. Anyone else have it?

After you get some output from the CPT interp program then I would recommend that you double check the output with a spread sheet of your own design.
I have found that it is necessary modify the results a small amount based on the area of the country that you are working in and local knowledge.
