Numerous recommendations were made by the Coroner impacting on all areas of the industry having responsibility for roof framing. At the request of key industry bodies and participants, the Minister for Planning established the Ministerial Taskforce on Trusses in May 2006. The Taskforce considered the Coroner’s Report and noted the comment in the Executive Summary that ...neither the builder nor the architect, engineer, software designer, truss manufacturer, roof contractor, roof tiler or Local Government authority took any responsibility for the overall integrity of the roof structure. A key issue for the Taskforce was to ensure that there are clear pathways of responsibility and accountability. It is important to ensure that all systems and procedures relating to the design, approval, manufacture, handling, installation and inspection of trusses, are robust and appropriate. While the Taskforce focused on prefabricated timber trusses as the basis for its deliberations, the Taskforce was mindful that any changes must also be applicable to steel and conventional roof framing. The Minister released the final report and recommendations of the Taskforce on 1 June 2008. The Government subsequently approved an implementation plan for the Taskforce recommendations with the amendments to the Development Regulations 2008 coming into effect on 1 July 2012. This guide has been developed to assist the building industry, councils and private certifiers to understand and apply the new rules related to design, documentation, assessment, approval, storage, handling, construction, and inspection of roof framing.
