6. Demolition Plan
A demolition plan should include but not be limited to, documentation of the following information:
• The method statement for demolition works should clearly indicate the sequence of demolition, approach to demolition and elements that require specialised methods of removal. Operators and staff involved in the demolition works should be well informed and well versed with how works are to be carried out, the sequence of such works and the safety precautions to be taken prior to the commencement of works.
• A permit to work system should be implemented for the demolition works. The supervisor should conduct a site check to ascertain that safety measures are in place to safeguard the workers entering the site. When all necessary measures are in place, the supervisor should then request for a joint inspection with the safety assessor. The safety assessor should be responsible to check that all safety precautions are in place and highlight any lapses in safety that have not been addressed. Upon confirmation by the safety assessor that all measures are in place, the permit to work should then be reviewed and subsequently endorsed by the Project Manager in charge of the site when safe working conditions are met. Note: Permit to work for demolition is typically issued at a per floor basis, to ensure that every floor is adequately inspected prior to commencement of demolition.
• A debris management system indicating the method of disposal, movement of debris from floor to floor and to the holding area and transportation of debris should be prepared.
Implementation of a permit to work system is a requirement under the Workplace Safety and Health( Construction) Regulations 2007.
7. Pre-demolition Work
• Glass and cladding on external walls should be removed prior to commencement of any demolition works.
• Services / utilities should be capped, diverted or protected prior to the commencement of any demolition works.
