Safe bearing capacity from SPT N-values, liquefaction screening and soil classification — IS 6403, Terzaghi, Meyerhof and Bowles.
Estimate safe bearing capacity from a borehole log in minutes. Apply N-value corrections (overburden, rod-length, hammer energy), compute SBC by four methods, and screen for liquefaction per IS 1893 and the NCEER simplified procedure.
See SBC from IS 6403, Terzaghi, Meyerhof and Bowles in the same chart — judge engineering scatter at a glance.
Cyclic stress ratio vs cyclic resistance ratio for every layer — flagged red where FS < 1.0.
Up to 20 soil layers per borehole with independent unit weight, water table and SPT corrections per layer.
The SBC profile exports straight into the Foundation Design module — no copy-paste between tools.
Layer thickness, soil type, SPT N-values and water-table depth.
Overburden (CN), rod length (CR), hammer energy (CE) and borehole diameter (CB) — toggle individually.
IS 6403, Terzaghi, Meyerhof and Bowles — settlement-controlled and shear-controlled SBC reported separately.
CSR vs CRR per layer with peak ground acceleration; layers below FS = 1.0 are flagged in red.
Sanity-check a soil consultant's SBC by running the same N-values through four methods.
Cities in seismic zones IV and V — liquefaction screening informs whether ground improvement is needed.
Where N < 10, SBC is settlement-controlled — Bowles vs Meyerhof gives different answers; the tool surfaces both.
Estimate SBC quickly to decide pad vs raft vs pile before full geotechnical investigation.
