Stage 02
Automated modelling
Member-level models from vector PDF drawings and drawing tables, with self-checks before anything else runs.
Platform 01 · EarthState Twin
From an ageing tower's drawings to a capacity an engineer can sign
EarthState Twin takes project files, drawings and sensor data for one structure, builds a checkable model, runs the code checks and returns a capacity assessment and a ranked repair list, with every step recorded.
Six stages, one audit trail
How a job moves through the twin
01
Record the files
Drawings, inspection records, sensor lists and site data are registered with their source and version.
02
Build from drawings
A member-level analysis model is built directly from the drawings, including vector PDF.
03
Bring in sensors
Measured wind, strain and acceleration are attached to the members and nodes they describe.
04
Check the twin
The model is compared with measurements before it is trusted, and the comparison is kept.
05
Reduced-order models
Fast surrogate models for prediction and scenario runs, checked against the full model.
06
Report
A capacity statement and repair ranking, with an audit panel and engineer sign-off.
How the AI is used
The language model drives the tools. It never makes up a number.
You can work through the twin in plain language. The model chooses and runs the platform's calculation skills; every value on screen comes from one of those skills, and the audit panel shows which one, with its inputs.
Signing remains the engineer's job. The twin prepares the evidence; it does not approve its own work.
Stages 03 and 04
Sensors and calibration
Gauges registered on model members, records checked and corrected, the twin calibrated and validated on a held-out event.
BIM from the same drawings
One source, two models
The same drawings that produce the analysis model also produce an information model: IFC4 members and assemblies classified to Uniclass 2015, materials to EN 10025-2, names following ISO 19650-2 with the UK National Annex, OIR, AIR and EIR to EN 17412-1, and COBie for handover.
Standards
Checked against
- EN 1990, EN 1991-1-4, EN 1993-1-1 and EN 1993-3-1
- EN 50341-1 for overhead lines
- EN 10025-2 and EN 10056-1 for steel and sections
- ISO 19650 series for information management
Verification
What has been checked, and what has not yet
| Drawing to model | Against an independent member model: 90% of members matched, 97% of nodes within 150 mm, natural frequencies within 3%, critical wind speed 40.0 against 40.9 m/s. |
|---|---|
| Solver and wind-load suites | All automated test cases pass. Independent engineering review is in progress. |
| Demonstration data | The showcase tower is a real 66 m double-circuit angle tower with anonymised drawing geometry and measured wind records. Strain data are synthetic and labelled as demonstration data. |
| Status | Research prototype. Runs locally on Windows or macOS; core functions work offline. |

Two demos, no sign-in
The function tour walks through every stage of a job. The analysis demo follows one structure from drawings to a signed result. Both use one synthetic 48 m tower.
