Stop buying engineering spreadsheets one at a time — own the whole toolkit.
The workbook already carries everything a complete, consistent deliverable needs. Fill in the inputs, review the outputs, move on to the next task — with documentation that looks deliberate, not improvised.
Everything in one file
Cable, conduit, transformer and lighting design
Panel board, generator and motor calculations
Power factor, voltage drop and short circuit analysis
Electrical safety programs and insulating design
Mechanical load lists, pump sizing and HVAC tools
And so much more!
Who uses it
Electrical and mechanical engineers who run the same routine calculations across projects.
Why engineers keep it open
Ready the moment you download — nothing to configure.
Unlocked formulas — adapt to your own codes and inputs.
Proven in practice — the same file working engineers use.
Proven — Chosen by 2 engineers to date.
