You can catch-up on details or any broadcast and downloads here.


A significant proportion of construction activities involve Temporary Works (TW). Failures in TW occur persistently in the construction industry causing injury and even death to construction workers. The speaker has extensive experience investigating temporary works failures and will make the case that all TW failures are preventable. He will discuss a variety of underlying causes and challenges in TW including:

  • People and responsibilities and the need for teamwork and collaboration;
  • The process of planning, designing and checking TW and incorporating safety by design;
  • TW construction on site, including change management and verifying as-builts.

The Hong Kong Temporary Works Forum in collaboration with the Hong Kong Construction Industry Council is relaunching an updated model TW procedure for the industry “Control and Management of Temporary Works” (C&MTW) which provides a framework for ensuring safety in TW management. The speaker will provide insights into the objectives of the C&MTW procedures as well as share experiences of managing risk in Access Scaffolds and Working Platforms (ASWP) and Concreting Temporary Works (CTW).
