Seismic design for mechanical HVAC systems is a crucial requirement in New Zealand construction. At Beattie Air, we specialise in delivering fully compliant seismic restraint systems that meet NZS 4219:2009 and other national standards. Whether it’s for a school, commercial tower, or high-end apartment development, we design and document every restraint in-house – saving you cost, time, and hassle.
PS1 to PS4 – Covered by One Team
We are proud to offer end-to-end seismic design from PS1 to PS4, all completed by our internal team. This includes:
– PS1 – Design Producer Statement
– PS2 – Design Review (if required)
– PS3 – Construction Verification
– PS4 – Construction Monitoring Sign-off
Our engineering team and experienced drafters work closely with our project managers to ensure seamless integration of seismic design with your HVAC installation.
That means fewer delays, tighter coordination, and no need to engage multiple consultants.
