Match the method to the building
A villa alteration, an occupied commercial property and an industrial plant create completely different risk profiles. The contractor should first establish what must be removed, what must remain, how loads will change and which operations or neighbouring assets require protection.
- Selective demolition for renovations and retained structures
- Controlled structural dismantling for dense urban locations
- Heavy mechanical demolition for large standalone assets
- Diamond cutting and robotic methods for low-impact work
What a credible proposal should contain
A reliable proposal is based on a survey and a defined scope. It should explain the intended sequence, temporary works interfaces, access, plant, exclusion zones, environmental controls and material routes instead of presenting only a lump-sum price.
- Site-specific method statement and risk controls
- Programme with engineering and approval hold points
- Dust, noise, vibration and traffic management
- Waste separation, transport and recovery strategy
Questions to ask before appointment
Ask who is responsible for engineering, approvals, utility isolation and daily supervision. Confirm that the proposed equipment can physically access the work zone and that floor loading, lifting and debris movements have been considered. Local permit requirements should always be confirmed for the specific asset and jurisdiction.
- Who signs off the demolition sequence?
- How are adjacent structures and live services protected?
- What happens if the surveyed condition differs from drawings?
- How will completion and waste movements be documented?
Project note
Guidance is the starting point. The site determines the method.
Every structure, access route and operating environment is different. Final engineering, approvals and controls should be based on verified project information and a site-specific assessment.
