Description

This Practice Advisory was issued in response to concerns about the collapse of the Stadium Southland roof in Invercargill during a snow storm on 18 September 2010. It provides guidance for owners, territorial authorities and practising structural engineers.

Scope

This Practice Advisory is to:

• alert building owners to the issues that the report has identified with this long span truss steel construction
• provide advice to building owners to enable them to instruct Chartered Professional Engineers to review their buildings
• alert practising structural engineers assessing existing long span roof trusses in buildings throughout New Zealand
• provide advice to territorial authorities.

It applies to all existing buildings throughout New Zealand:

• that have long span roof trusses (over 20 metres) fabricated from welded closed steel hollow sections such as circular and rectangular tubes
• and to which members of the public have access.
