Demolition, Dismantling and Structural Alteration
Surveys, structural method and sequence, services and hazardous materials, exclusion, plant, dust and public protection.
How to prepare for the CITB MAP test
Build manager-level decisions around role, prevention, coordination, verification and learning rather than memorising isolated site rules.
Core concepts
Concept 1
Demolition and structural alteration need competent planning based on reliable structural, service and hazardous-material information.
Exam cue: Survey the structure and surroundings before choosing the demolition method.
Concept 2
The written arrangement defines sequence, temporary stability, plant, exclusion zones, falling material and emergency controls.
Exam cue: Isolate and prove services and maintain structural stability at every stage.
Concept 3
Premature collapse, work at height, asbestos, dust, noise, vibration, fire, plant and public interfaces are managed together.
Exam cue: Stop when the structure or materials differ from the plan.
Risk pitfalls and guardrails
Starting soft strip or structural removal before adequate surveys.
Guardrail: Do not solve a design, engineering or organisational failure only with a briefing, warning sign or PPE.
Changing sequence or removing a load-bearing element without engineering review.
Guardrail: Do not solve a design, engineering or organisational failure only with a briefing, warning sign or PPE.
Using an exclusion zone to excuse uncontrolled collapse or debris.
Guardrail: Do not solve a design, engineering or organisational failure only with a briefing, warning sign or PPE.
Memory anchors
Survey Before Sequence
Understand structure, condition, services, hazardous materials and neighbours.
Written Demolition Arrangement
Define a safe method and sequence before demolition or dismantling begins.
Stability at Every Stage
Control temporary and remaining structure as loads and supports change.
Isolate Services
Locate, disconnect, prove and manage all incoming and embedded services.
Exclude and Contain
Protect workers and the public from collapse, plant, debris, dust and flying material.
Unexpected Means Stop
Unplanned structure, movement or material requires competent reassessment.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
