Modulus is the AI workbench for MEP and structural engineers. It drafts the full design package — SLDs, cable schedules, calc sheets with every clause cited — and leaves the sign-off to you.
Built on IS 732 · IS 3043 · IS 13234 · IEC 60617 — 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.
An LV package for one building means hundreds of feeders, each sized, derated, checked and cited by hand in Excel and AutoCAD. The judgment takes an afternoon. The paperwork takes weeks.
Load list in. Stamp-ready package out.
Drop in your load list
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, SLDs 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 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 derating
- —Cable, breaker and busbar sizing
- —Fault levels and earthing
- —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.
Built by an engineer and an engineer.
An AI engineer who ships RAG and agent systems, and a licensed structural engineer who owns calculation correctness. Liability and sign-off stay with the professional — exactly as with STAAD or AutoCAD.
