Engineering Disclaimer

Draft — operator details are pending and this text should be reviewed by counsel before launch.

All results produced by Online Calculate are computer-generated calculation outputs intended for preliminary checking and education.

• They are not certified designs and are not endorsed, reviewed or signed by a Professional Engineer. Reports carry this statement and must not be submitted to any authority as an engineer's calculation.
• Each calculator states its method, assumptions and limits of applicability, and where a design standard is used, the standard, edition and National Annex. Using a calculator outside those limits gives meaningless results.
• Results depend entirely on your inputs, including load values, load factors, material properties and units.
• Engines are deterministic and benchmarked against independent reference calculations before release, and each calculator shows its version and verification status. Errors may still exist — report suspected errors via the contact page.
• Any design for construction must be prepared or checked by a suitably qualified and registered person in accordance with the applicable regulations.
