Suspended ceilings must be designed to withstand ultimate limit state (ULS) level earthquakes in order to comply with Clause B1 of the NZ Building Code using verification method B1/VM1. As a result Consent Authorities now require site specific PS1 designs for building consent purposes instead of generic supplier designs.
An independent, registered Structural Engineer can produce site specific PS1 designs that lead to design, cost and on-site construction efficiencies. Projects requiring specific seismic designs will also require construction monitoring and a PS4 Construction Review Statement to ensure the seismic details are actually installed in accordance with the design.
