Demolition

Survey first, follow the PE's sequence, keep the collapse zone clear, never hack bottom-up.

Key points

  • Demolition is high-risk construction work in Singapore. No permit-to-work from the project manager, no demolition.
  • Survey the structure, services and hazardous materials first. Buildings put up before 1 January 1991 need an asbestos survey.
  • Removing columns, beams, floors or other load-bearing parts follows a method statement prepared by a professional engineer.
  • Work from the top down. Keep a barricaded collapse zone and let nobody into it but the people doing the work.
