If your name goes on the drawing, it should look like it.
Most engineers still hand clients a screenshot of an Excel cell. That's not the problem — the problem is what it signals.
Built for the engineer you actually are
Four workflows, one suite. Pick the one that sounds like your week and start free.
Bill more, sweat less
Replace 6 brittle Excel files with one stamp-ready tool. AI sanity-checks every result before it hits the client.
One source of truth for the team
Shared seats, your company name and logo on every PDF, VAT/Tax ID on invoices. Junior engineers can't go off-template.
No black boxes. Every number is auditable.
- 1Every formula is shownOpen any calculator — you see the equation, the inputs, the assumptions, and the code reference.
- 2Every result cites a standardIBC, ACI 318, IS 456, NEC, ASHRAE, ISO 8528, NFPA 110, ISA & IEC 60534 — the AI cites the clause.
- 3Your data stays yoursCalculations are private to your account. We never train models on your projects. Export everything at any time.
- 4AI fulfills support 24/7Ask anything in-app — the assistant answers in <30s. Replies to support@enginesuite.app are handled by AI with a human reviewer for billing.

Five disciplines. One workflow.
Stop juggling spreadsheets. Get every key calculation, with the right code references, in one validated tool — now including full instrumentation design.
Architectural
Occupancy load (IBC), FAR, parking, stair sizing, WWR, LPD.
Civil / Structural
Beam analysis, reinforcement (IS 456 / ACI 318), columns, footings.
Electrical
FLA, voltage drop, transformer kVA, domestic & industrial loads, generator sizing.
Mechanical / HVAC
Cooling load, duct & pipe sizing, pump & fan power, U-value.
Instrumentation
4-20mA loop scaling, control valve Cv, orifice flow, RTD, tray fill.
Like having a senior engineer on call.
Ask any question about your design: "Is this beam OK for L/d?", "Why is my voltage drop above 3%?", "What does ASHRAE recommend for this duct velocity?" — and get a clear, code-aware answer in seconds.
- Cites IBC, ACI 318, IS 456, NEC, ASHRAE, ISO 8528, NFPA 110, ISA & IEC 60534
- Explains your own calculator results in plain English
- Flags assumptions and recommends safety factors
- Drafts client-ready summaries on demand

Engineers love it
"Cut my preliminary sizing time by 70%. The PDF reports alone are worth it."
"The generator sizing flow is exactly what I needed. Replaced three spreadsheets."
"Asking the AI to sanity-check my duct velocities has saved at least one mistake a week."
