- Calculate Safe Bearing Capacity (SBC)
- Apply overburden and dilatancy corrections
- Generate and download professional PDF reports
- Calculates SBC using corrected SPT N-values
- Includes overburden and dilatancy corrections
- Displays effective stress, correction factor, and all intermediate results
- Reference soil weight table
- PDF Report Generation with:
