Release of technical updates to concrete buildings

The release of an additional revised version of section C5 will be available on Friday 30 November 2018 and is a technical proposal to be known as the ‘revised (yellow) section C5’. 

In October, an update was sent on the future status of section C5 ‘Concrete Buildings’ in the Engineering Assessment Guidelines. This is used by engineers for the seismic assessment of concrete buildings and is part of the earthquake-prone building (EPB) management system legislation introduced on 1 July 2017.

 

The update advised about the upcoming release of an additional revised version of section C5. This will be available on the EQ-Assess.org.nz website on Friday 30 November 2018 and is a technical proposal to be known as the ‘revised (yellow) section C5’. That means there are two versions of section C5 available for the next few years.

 

  1. Engineers are encouraged to use the revised (yellow) section C5 when carrying out seismic assessments that are not EPB related. It has updated technical provisions related to existing concrete buildings, and includes engineers’ latest thinking on precast concrete flooring.
  2. Section C5 in the Engineering Assessment Guidelines is still mandatory for the seismic assessment of potential EPBs.

 

Remember, MBIE is not making any changes to the system for managing earthquake-prone buildings introduced on 1 July 2017, including the Engineering Assessment Guidelines.

 

Over the next few years, MBIE and Engineering New Zealand are working together to gather and consider feedback on the use of the revised (yellow) section C5. MBIE wants to know how the technical changes to section C5 would change assessments of potential EPBs before consideration is given to incorporating it as legislation, into the Engineering Assessment Guidelines.
