PMDCS website content, technical articles, examples, calculators and digital tools are intended to support professional understanding and preliminary assessment. They are not a substitute for project-specific investigation, design, approved procedures, statutory requirements, contract documents or competent engineering judgement.

Conditions on infrastructure projects can change rapidly and may depend on geology, hydrology, construction method, equipment, temporary works, access, environmental conditions and other factors that are not captured by a general website tool.

Users should independently verify assumptions, input data, code requirements and outputs before applying any information to a live project. Final decisions remain with the appropriately authorised project team and responsible professionals.
