Demolition Method Statement

Demolition › Specific › Demolition Method Statement

Presenter		Project
Location		Date

A demolition method statement defines the planned sequence, methods, and safety controls for the demolition.
BS 6187 and CDM 2015 require a written method statement before any demolition work begins.
The method statement must be prepared or reviewed by a competent demolition engineer.
It covers the structure type, condition, services, asbestos, and any constraints affecting the work.
The planned sequence of demolition is critical — removing elements out of order causes uncontrolled collapse.
Temporary works required during the demolition, including propping and shoring, must be defined.
Exclusion zones, dust and noise controls, and environmental protection measures are specified.
The method statement must address emergency procedures specific to the demolition operation.
All site operatives must be briefed on the method statement before starting any demolition activity.
The method statement is a live document — it must be updated if conditions change during the works.

Prevent collapse	The demolition sequence is the primary control against uncontrolled structural collapse — the method statement defines it.
Legal requirement	BS 6187 and CDM 2015 mandate a written method statement before demolition work can commence.
Communication	The method statement ensures every worker understands the plan, sequence, hazards, and their specific role.

Don't

Commission a competent demolition engineer to prepare or review the method statement
Include the structural assessment, asbestos survey, and service identification findings
Define the demolition sequence clearly showing which elements are removed and when
Specify all temporary works needed to maintain structural stability during demolition
Detail exclusion zones, dust suppression, noise controls, and environmental measures
Include emergency procedures specific to the demolition method and site conditions
Brief all operatives on the method statement before they start any demolition work
Keep the method statement available on site for reference throughout the operation
Update the method statement if site conditions or structural findings change
Obtain client and principal contractor approval before the method statement is enacted

DON'T start any demolition work without a completed and approved method statement
DON'T deviate from the approved demolition sequence without engineer approval
DON'T use a generic method statement — it must be specific to the structure and site
DON'T allow operatives to work without being briefed on the current method statement
DON'T ignore new information about the structure — update the method statement
DON'T remove temporary works or shoring that the method statement requires to remain
DON'T rely on verbal instructions for complex demolition sequences — use the written plan
DON'T treat the method statement as a one-off document — review it throughout the works
DON'T allow unqualified persons to prepare demolition method statements
DON'T proceed if the pre-demolition survey reveals conditions not covered by the method statement
