Scope & positioning

StructCalc is a software tool. It is sold to and operated by licensed structural engineers, in the same way as RISA, SkyCiv, ETABS, or a spreadsheet. It is not, and does not hold itself out to be, a practice of engineering.

What StructCalc does

Given building and site parameters, or an uploaded analysis model, StructCalc computes code quantities using pure, versioned functions and assembles them into a preliminary, clause-cited calculation package. Every quantity carries the standard, edition, and clause it derives from, and the formula with the user's values substituted in.

What StructCalc does not do

It does not exercise engineering judgment. It does not select load paths, choose which provisions govern, decide applicability, or approve a design. Where a value cannot be verified against the official standard, the software refuses it rather than guessing. Anything requiring judgment is surfaced as an item for the Engineer of Record.

The Engineer of Record

A licensed professional engineer is responsible for reviewing, judging, correcting, and sealing every package before it is used. Until reviewed and sealed by that engineer, output is preliminary and not for construction. This statement appears on the cover and every page of every document StructCalc produces.

No warranty of fitness

StructCalc is provided as a computational aid. The user, as the licensed professional, remains solely responsible for the correctness and adequacy of any design. Normative constants are validated against published examples and are subject to the user's own verification against the official standard text.

Preliminary — for review by the Engineer of Record. Not for construction until reviewed and sealed by a licensed professional engineer.
