Modulus is the AI workbench for structural and MEP engineers. It drafts the full design package — calc sheets with every clause cited, drawings, schedules and the walkthrough report — and leaves the sign-off to you.
Built on IS 456 · IS 875 · IS 1893 · IS 732 · IS 3043 — deterministic engine, zero LLM arithmetic
Feeder sizing MLTP → SMDB-L1
Passes with no margin. Modulus won't pick the fix — upsize the MCCB, rebalance phases, or accept?
Review as SEDemo project · engine output · clause registry pending SE validation
Senior engineers spend weeks on work a checker should take hours.
A frame, a foundation, a building's electrical services: the engineering judgment takes an afternoon. Sizing every member and circuit, citing every clause and drawing every sheet takes weeks, by hand in Excel and AutoCAD.
Brief in. Stamp-ready package out.
Drop in your brief
Excel, PDF or a plain-language brief. Modulus reads it and asks you about anything missing or unclear.
A deterministic engine does the math
Plain Python implementing IS formulae and tables. The AI orchestrates and explains — it never calculates.
You review, redline and stamp
Every stage is a checkpoint. Calc sheets, drawings and the walkthrough report land ready for your seal — not instead of it.
The AI narrates. It never calculates.
A calculation that's 80% right is more dangerous than none at all. So every safety-critical number comes from auditable code your engineer can read against the printed standard.
The language model
- —Reads briefs, drawings and load lists
- —Finds the governing clauses
- —Sequences the workflow
- —Writes the report prose
- —Flags what it doesn't know
The calculation engine
- —Load factors and combinations
- —Member, cable and breaker sizing
- —Seismic, wind and fault levels
- —Utilization and pass / fail
- —Checked against hand-solved problems
Built like a professional instrument.
Plan mode for precision. Agent mode for speed.
New users approve every stage: brief, plan, loads, analysis, results, drawings, report.
Full audit trail
Every calculation, clause and assumption — timestamped and exportable.
Works with your tools
A small desktop agent bridges to licensed software already on your workstation.
Every discipline, one project
Checked, not vibes
Every engine module has hand-solved reference problems. A licensed engineer reviews them before any module reaches real projects.
Made by engineers, for engineers.
Design engineers and software engineers, building the tool we wanted on our own jobs: one that takes the drafting and paperwork off the engineer and leaves the judgment with them. Liability and sign-off stay with the professional — exactly as with STAAD or AutoCAD.

We're working with a small group of EPC, structural and MEP consultancies in India. Free during the pilot.
