Issue 41 – August 2012
The Ministry of Business, Innovation and Employment's (MBIE's) Building Controls Update 134 covers learnings from Stadium Southland and HERA seminars about structural welding.
Learnings from Stadium Southland – HERA seminars about structural welding
In response to learnings from the September 2010 collapse of the Stadium Southland roof during a snowstorm, the Heavy Engineering Research Association (HERA) is running a series of 1-day seminars on structural welding.
Why the Stadium Southland roof collapsed
Investigators found remedial works (including steel fabrication and welding), carried out when sagging of the roof was observed during construction, were insufficient to ensure the integrity of the stadium. The deficiency in steel fabrication and welding demonstrated inadequate supervision of the remedial construction work.
Preventing this from happening again
The former Department of Building and Housing, now part of the new Ministry of Business, Innovation and Employment, released the results of their investigation on 5 June. A week later Practice Advisory 14: Long span steel roof trusses – welding and section checks needed for some was released. The practice advisory provides guidance for building owners, territorial authorities, and practising structural engineers.
Learn more at HERA's August 2012 seminars
The HERA seminars are a great opportunity to learn more about the principles of quality assurance for welded steel structures and will provide practical guidance on what to look at, look out for, and when and where to go for assistance. The seminars will be held throughout New Zealand, from 21 – 30 August, 2012.
