The limits of this engineering guide

This website is published by Pavilionvaultbambo Ltd. Its articles, tables, images and tools provide general information about earthquake-resistant residential engineering. They do not constitute structural calculations, a survey, a building assessment, a professional appointment or advice tailored to a particular property.

Do not use the content to choose member sizes, reinforcement, fasteners, anchor embedment, foundations or construction sequences. Conceptual images omit information required for safe construction. Only appropriately qualified professionals working within the applicable jurisdiction and project scope can determine suitable interventions.

We do not guarantee earthquake safety, code compliance, freedom from damage, insurability or continued occupancy. A building’s response depends on factors including shaking, soil, configuration, construction, condition and maintenance.

We aim to explain technical principles carefully, but content may contain errors or become outdated. Verify critical information against current primary sources and the provisions adopted by the relevant authority. Standards named here may not apply in your location or to your building.

Links to external organisations are provided for context and further reading. They do not imply endorsement or affiliation. We do not control external content, availability, terms or privacy practices.

You may read and link to these pages and make reasonable personal-use copies with attribution. Except where permitted by law or separately authorised, do not reproduce substantial portions of the site commercially or present its diagrams as approved construction details. Third-party names and materials remain subject to their owners’ rights.

Do not misuse the site, attempt unauthorised access, interfere with its operation or use its contact details to send unlawful or abusive material.

The contact-page tool formats your own entries as a plain-text brief. It does not validate facts, diagnose structural conditions, calculate capacity or submit a message. You are responsible for reviewing the draft, protecting downloaded files and deciding what to share with a professional.

The website may be updated, interrupted or withdrawn. To the extent permitted by law, we do not accept liability for losses resulting from reliance on general content instead of obtaining suitable project-specific advice. Nothing in these terms excludes or restricts liability for death or personal injury caused by negligence, fraud, fraudulent misrepresentation or any liability that cannot lawfully be excluded. Your mandatory statutory rights remain unaffected.

These terms are governed by the law of England and Wales, without removing any mandatory protections available to you in your place of residence. Applicable consumer rules concerning jurisdiction continue to apply.
