Axis Plumbing NZ, on behalf of Aquaheat undertook the HVAC piping and Gas services at Wiri Prison. With 25 buildings across the 17Ha site, this site posed a unique set of challenges.
The site wide gas reticulation was completed in PE pipe and electro fusion couplers and totalled over 3km. The HVAC system comprises of a chilled water central plant with an in ground Insa Pipe PPR reticulation feeding the health, Admin and reception buildings and a localised Heating water plant room in each building requiring heating. This project was a GMP and held significant risk in terms of partially complete drawing and design at time of tender. This job has progressed well with our site team even winning an award for outstanding commitment to safety.
