Product Overview

This risk assessment covers structural heavy demolition and induced collapse activities, including planning, pre-weakening, mechanical demolition, pulling operations and post-collapse checks. It supports planning and risk management by addressing structural instability, debris, plant, services and site interfaces.

Activities & Risks Covered

This assessment addresses activities and risks including:

  • Plan demolition methods, engineering review and site assessment
  • Confirm services isolation and hazardous materials information
  • Set up exclusion zones, public protection and traffic controls
  • Prepare demolition plant, attachments and ground conditions
  • Manage pre-weakening work and temporary structural stability
  • Undertake mechanical demolition of walls, columns and elevated elements
  • Control pulling operations, wire ropes, chains and remote collapse initiation
  • Manage work at height, access and falling-object risks
  • Control dust, noise, vibration and airborne contaminants
  • Verify post-collapse stability and prepare for emergency response

Who is this for?

Suitable for contractors, workers, supervisors and businesses carrying out structural heavy demolition or induced collapse activities.

Activities & Hazards Covered

Activity Potential Hazards
Planning, engineering review and site assessment
  • Unexpected structural instability or premature collapse
  • Incorrect demolition method for the structure type or condition
  • Hidden load paths, damaged members or deteriorated materials
  • Insufficient clear fall zone for induced collapse
  • Weather effects such as wind increasing instability
Services isolation and hazardous materials confirmation
  • Contact with live electrical services
  • Gas release, fire or explosion from unisolated services
  • Flooding, pressure release or uncontrolled discharge from water or process lines
  • Exposure to asbestos, silica, lead or other hazardous materials disturbed during demolition
Establishment of exclusion zones, public protection and traffic interface
  • Workers or the public struck by falling debris
  • Unauthorised entry into the collapse zone
  • Vehicle or pedestrian interaction with demolition plant
  • Exposure of adjacent properties or road users to collapse debris and dust
Plant setup, attachments and ground conditions
  • Plant overturning due to poor ground bearing capacity or edge collapse
  • Attachment failure or dropped demolition tools
  • Workers struck by slewing plant or moving equipment
  • Operator injury from falling material onto the cab
Pre-weakening and temporary stability
  • Premature collapse during removal of key members
  • Loss of stability from partial cutting of loadbearing members
  • Collapse from wind, vibration or accidental impact after pre-weakening
  • Workers struck by falling sections or dislodged materials
Mechanical demolition of walls, columns and elevated elements
  • Falling masonry, concrete or steel striking workers or plant
  • Edge falls through lift wells, stairwells, light wells or floor perimeters
  • Flying debris from breakers, shears or pulverisers
  • Instability from unsupported or partially severed members
Pulling operations, wire ropes, chains and remote collapse initiation
  • Whiplash or recoil from rope, sling or chain failure
  • Plant sliding, lifting or overturning under load
  • Uncontrolled direction of collapse
  • Workers positioned in the line of pull
Working at height, access and falling objects
  • Falls from edges, voids, incomplete floors or access systems
  • Dropped tools or materials striking workers below
  • Collapse of temporary access or work platforms
  • Unsafe access during inspections, cutting or removal tasks
Dust, noise, vibration and airborne contaminants
  • Respirable silica and nuisance dust exposure
  • Reduced visibility affecting plant operation and evacuation
  • Excessive noise causing hearing injury or missed warnings
  • Vibration affecting nearby structures or worker health
Collapse event, post-collapse verification and emergency response
  • Workers re-entering before the structure or debris pile is stable
  • Secondary collapse or rolling debris after the main event
  • Entrapment, injury or delayed emergency response
  • Fire, gas leak or other residual energy release after collapse
