Structural engineering
“The software has made us a minimum of 30% more productive. It’s eliminated at least 30% of the workload.”
Donovan Rae

Where engineering decisions get made and defended
Every formula, code provision, and product rule is visible inside the calculation. Decisions get made, checked, and defended where the work happens, not reconstructed later.

- [ 01 ]
Calculations are isolated
Spreadsheets, legacy tools, and one-off files.
- [ 02 ]
Standards are separate
PDFs, folders, and paywalled portals.
- [ 03 ]
Product data is elsewhere
Catalogs, submittals, and email threads.
- [ 04 ]
The trace is missing
Load cases, combinations, governing checks, and code clauses are not tied to each result.
- [ 05 ]
Changes are hard to audit
Logic is spread across cells, hidden tabs, and copied workbooks.
- [ 06 ]
Old clauses keep circulating
Standards updates rely on manual spot checks across copied files.
Put the basis of design inside the calculation
Calcs.com keeps inputs, formulas, and code references together so reviewers can inspect the logic before they rely on a result.
One calculation, four ways in
Engineers run it. Manufacturers embed their products in it. Standards bodies govern how their clauses are applied. Software vendors call it from their own products.
- [ 01 ]Run
Start with a standards-aligned check and clean inputs.
- [ 02 ]Review
See the governing formula and code clause before you rely on the result.
- [ 03 ]Reuse
Carry the basis of design forward without rebuilding the calc.
