Build a defensible ground model
Bring your CPTs, seismic data, and desktop sources into one environment. Iterate ground models that hold up under regulatory review and inform foundation decisions.
steno
Site investigation, end-to-end
From desktop study to foundation design — all in the browser. No file handoffs between tools, no translation between teams. One environment for your geotechnical, geophysical, and engineering disciplines.
Open platformWhat it isFor developers For authorities For consultants
Three points of view. One platform.
Host your tender data room — not a static file package
Replace a static data package with an interactive ground intelligence environment. Registered bidders access the live ground model, download data in standardised formats, and work from the same authoritative dataset.
Deliver work, not infrastructure
Stop wrangling files and toolchains. Run your QI workflow, integrate with client datasets, and ship findings — all in the browser.
The name
Nicolaus Steno
Nicolaus Steno (1638–1686) was a Danish anatomist and bishop who, while dissecting a shark's head in Florence, came to recognise that fossils were once living things. From this came his principles of stratigraphy — the law of superposition, the principle of original horizontality, the principle of lateral continuity — the foundation on which every ground model still rests.
Beautiful is what we see. More beautiful is what we know. Most beautiful, by far, is what we do not yet understand.— Nicolaus Steno
The platform borrows his name and his method: every interpretation should be traceable, every layer should be defensible, and every ground model should be an honest expression of what is and is not yet known. That principle runs through every module.
What Steno does
A sample of how teams use it — the platform adapts to your project's workflow.
Strategic
One environment for all disciplines
Geotechnical, geophysical, and structural engineers working from the same data and shared models — no file handoffs between tools.
Technical
CPT interpretation
Robertson classification, su, Dr, G0 derivation, EC7 characteristic values — on every CPT in your project.
Technical
3D ground modelling
Geostatistical kriging, seismic-unit framework, block model and property volumes from CPT and seismic data.
Technical
Foundation design
Axial capacity, driveability, and PISA lateral scaffold — calculated across all WTG locations from the shared ground model.
Technical
Visualise and slice the ground model
Interactive 3D viewer, cross-sections anywhere, seismic-unit maps — explore the model directly in the browser. No desktop software.
Technical
Wind, metocean and WTG layout
Wind resource, wave and current loading, WTG positioning — connected to the ground model and CAPEX heatmap in one view.
Strategic
Procure the right investigation
Generate technically specified ITT/RFPs from your ground model. Identify data gaps before commissioning fieldwork.
Strategic
Tender data room for authorities
Replace a static data package with a live ground intelligence environment. Bidders access the model directly.
Communication
Results that speak across the organisation — and beyond it
A shared browser environment means ground model findings are as legible to a project director or lender as they are to the geotechnical engineer who built them. No PowerPoint exports of static screenshots.
Within your team
Geotechnical, geophysical, and structural disciplines working from one live model — not emailed exports or fragmented tool chains.
Across the organisation
Project directors and investment committees see the same ground model as the technical team — in the browser, with no translation layer.
Outside the company
Share with lenders, authorities, JV partners, and regulators. Watermarked access, full audit trail, no data room setup required.
