Demolition and Removal of Concrete Pavement, Kerbs and Footpaths – Method Statement

AI-assisted method statement with matching ITP, PDF download, and Excel export.

Published 27 Oct 2026 Rev. 00 2 views
About this method statement: This method details safe, controlled demolition of concrete pavements, kerbs, and footpaths using excavators and breakers. It covers TMP, dust/noise/vibration control, waste segregation, and subgrade proof-rolling and testing with full QA/ITP.

More than a static template

Unlike a downloadable Word or PDF template, this method statement is an AI-assisted editable starting point connected directly to a matching Inspection and Test Plan. Every section is structured, project-adaptable, and ready to export.

  • AI-assisted drafting — Customize every section with AI for your specific project scope.
  • Linked ITP — A matching inspection and test plan is generated alongside the method statement.
  • Multiple export formats — Download as a formatted PDF or editable Excel spreadsheet.
  • Editable starting point, not a final document — Review, verify, and adjust all content against your project requirements before use.

Why this method statement is used

This method statement is used to define and communicate the approved procedure for carrying out demolition and removal of concrete pavement, kerbs and footpaths on site. It ensures the work is planned in advance, the correct resources and controls are in place, and all personnel understand responsibilities, sequence, quality requirements, and safety controls before work begins. It aligns site execution with the documented scope and acceptance expectations.

Who uses this method statement

This method statement is used by contractors, site supervisors, project engineers, QA/QC engineers, HSE officers, consultants, and client representatives. It serves as a shared reference for planning, execution, supervision, inspection, and approval of the activity on site.

When it is prepared and submitted

The method statement is prepared before the work activity starts and submitted as part of the pre-construction documentation package for review and approval.

Who reviews or approves it

The method statement is usually submitted to the client representative, consultant, resident engineer, or project management consultant for review and approval before the work commences.

Important approval note

This method statement is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all content must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.

For example: if your specification requires a departure from a referenced standard, that departure must be documented and approved separately — this method statement will not capture that automatically. Always verify against your applicable drawings, specifications, and regulatory requirements.
