Demolition & Enabling Works Flashcards
(25 cards)
What is the purpose of enabling works?
To prepare the site for construction by clearing obstacles, adjusting utilities, and establishing access.
What is a demolition method statement?
A document that outlines how demolition will be safely planned and executed.
What regulation covers demolition in the UK?
CDM Regulations 2015.
What is soft-strip demolition?
The removal of non-structural elements like fittings, partitions, and finishes before main demolition.
What is facade retention?
A technique to preserve historic or architectural facades while demolishing internal structures.
What are the main risks in demolition?
Structural collapse, hazardous materials, dust, noise, and vibration.
What is a structural survey used for in demolition?
To assess building stability and develop a safe demolition sequence.
Name three common demolition techniques.
Mechanical, controlled explosion, and deconstruction/manual dismantling.
Why is asbestos a major concern in enabling works?
It is hazardous when disturbed and must be removed by licensed contractors.
What is the purpose of a demolition exclusion zone?
To restrict unauthorized access and protect people from falling debris or collapse.
What role does dewatering play in enabling works?
Removes groundwater to stabilize soil before foundation or excavation begins.
What document outlines recycling requirements for demolition waste?
The Site Waste Management Plan (SWMP) or part of the RAMS.
What is the HSE’s stance on demolition safety?
Risk assessments, qualified supervision, and following CDM duties are essential.
Why are method statements and risk assessments paired?
Together they identify hazards and describe control measures for specific activities.
What are common enabling works?
Hoarding setup, tree protection, drainage diversions, and scaffold erection.
How is demolition sequencing important?
Prevents structural instability by ensuring materials are removed in a safe order.
What is site clearance?
Removal of vegetation, debris, and obstacles from the site surface.
What is a temporary works engineer responsible for during demolition?
Designing shoring, supports, and braces to ensure safety during the process.
What is the environmental impact of demolition?
Includes noise, vibration, air pollution (dust), and landfill waste.
What are controlled demolition techniques?
Precision methods like robotic demolition or explosive charges used safely.
What is a pre-demolition audit?
An assessment of materials and hazards present before work starts.
What is the difference between structural and non-structural demolition?
Structural removes load-bearing elements; non-structural focuses on interior components.
What is scaffold encapsulation?
A protective wrap around scaffolding to control dust and debris spread.
Why is phased demolition used?
Allows for better control and safety in complex or urban environments.
