Disclaimer

All tools and articles on Geotechnical Insights Hub are provided "as is" without warranties of accuracy, completeness, merchantability, or fitness for a particular purpose.

Calculations are simplified and may omit project-specific factors such as groundwater variability, construction sequence, seismic loading, layered subsurface behaviour, and code-specific modifiers.

Outputs are indicative only and must not be used as final design values. Always perform qualified, project-specific engineering review and applicable code checks.

To the fullest extent permitted by law, the website owner disclaims liability for direct, indirect, incidental, consequential, or professional losses arising from use of the site content or tools.

Design Use and Responsibility

• -The tools on this site are intended for education, rapid screening, early-stage comparison, and assumption testing only. They are not a substitute for full project-specific analysis or formal design.
• -Before any value from this site is used in design, reporting, procurement, construction planning, risk assessment, or professional advice, the calculations, inputs, assumptions, units, and engineering relevance must be independently checked by a suitably qualified engineer.
• -Project-specific ground investigation, laboratory testing, groundwater assessment, load definition, construction sequence review, and applicable code compliance checks remain essential in all cases.
• -No responsibility or liability is accepted for direct or indirect loss, technical error, design inadequacy, construction outcome, delay, claim, or damage arising from reliance on these tools, articles, or any derived interpretation.
• -The user remains solely responsible for selecting appropriate parameters, confirming applicability, interpreting outputs correctly, and establishing all final design values.
