Eva · AI structural engineer

Become a
10x structural
engineer.

Eva is an AI that reads your drawings, builds the BIM model, runs the FEA analysis, checks the results and drafts the report. One great engineer with Eva delivers what used to take a whole team.

The 10x structural engineer

Don't grow the team.
Multiply your best engineer.

More work usually means hiring more drafters and engineers, then training, coordinating and checking them. With Eva, your strongest engineer stays on judgement and design decisions while Eva does the hours of extraction, modelling, analysis set-up and documentation.

How Eva works

From drawings to a checked report.

Step by step, with you in charge. Eva follows the workflow a careful engineer would, and each step is a skill your team can run, review and repeat.

Extract

Geometry, sections, materials and loads are pulled from existing models, PDFs and reports into tables, each with its source.

/extract

Design basis

Codes, materials, loads and criteria are written up for your approval. Anything missing is listed as additional information required from the client.

/design-basis · /questions

Analyse in FEA

In your FEA solver (ETABS, SAP2000 or RISA-3D), loads and load combinations are applied and the analysis runs for any scenario you choose.

/loads · /analyse

Model in BIM

The model is built in your BIM software (like Revit) with materials assigned, ready to go.

/model-[software]

Check & verify

Load balance, drifts, modal behaviour and outliers are checked, with independent hand calcs and a checker-style review.

/check · /hand-calc · /review

Report

A clean, easy-to-read report for your client with every assumption and every option checked, so there is no doubt you made the best decision.

/report · /milestone

Real deliverables

This is what Eva hands your engineer.

Excerpts from checks and reports Eva produced on real industrial projects, anonymized: verdicts first, every ratio shown, independent checks side by side.

Verdict cards from a model check: failing floor girders, a monorail that needs a larger section, a monorail that needs a support, and the rest of the structure passing
Verdict first. Each check opens with a plain-language verdict: what fails, by how much, and the section that fixes it.

Ratios on the model. FEA demand/capacity results written back into the BIM model, coloured, with the members to replace marked.

Model QA. A drafter's BIM model read, rebuilt in FEA and re-checked, with every changed member traced.

Eva in action

Real screens, on real projects.

Captured from Eva in use, in both of its modes. In the browser, Eva works on a licensed Windows workstation that you watch live next to the chat. With Eva Desktop, it works right on the engineer's own PC, in the software they already have open.

Built for engineering firms

Fast, and fully accountable.

  • The engineer approves. Eva proposes the design basis and decisions, and nothing is issued without sign-off.
  • Sources for everything. Values trace back to the drawing or report they came from, and gaps are listed.
  • Full project history. Every turn is saved as a version you can compare or restore.
  • Your machines, your licences. Work runs on your Windows VMs or engineers' own PCs with Eva Desktop.
  • Dedicated infrastructure. Eva is set on infrastructure dedicated to you and your firm.
  • Admin control. Users, roles, reviewers, workstations and skills are managed in one console.

About Eva

Eva is an AI, and she says so.

We gave Eva a face because she's a colleague your team talks to every day. She is not a person and never pretends to be one. She's the visible side of a system that does the heavy lifting so your engineers can do the engineering.

  • Speaks plainly, sources everything, asks when unsure
  • Remembers project decisions across conversations
  • Works for your engineer, never around them
