WestPac Helicopter Hanger – Framing

Ardmore July 2019
We recently had the opportunity to supply our products to the new Westpac Rescue Helicopter Trust. These guys do an amazing job helping Kiwis New Zealand wide when they are in danger or when they need to be flown urgently to hospital. So, it was great to be able to help them on this project.

Project Intent

Westpac Rescue Helicopters recently moved from their previous base in Mechanics Bay to Ardmore. They have a modern building with plenty of space for their helicopters, training facilities and staff quarters.

Project Challenges

There were a few challenges for the builders like having to achieve less than 40db inside the staff quarters. No mean feat when 50db is the norm in an empty lounge at home, here at Ardmore you have Harvards and helicopters taking off all day. Another challenge was getting the BK117 Bolkov Kawasaki 117 helicopters inside the hanger. Unfortunately, the doors on the hanger were set too low for the helicopters to fit. Two new 15m wide by 5m high door openings needed to be designed and built. The doors are self-supporting and held up by Structural Steel beams at each end. This allowed for the shed structure to be lightweight.

Material Construction/Assembly

The previous owners of the building Stonebridge engaged Hamish of Mac Consulting who came up with an extension for the front of the existing C Purlin and Tophat Portal Shed. He utilised Back to Back Central Steel Framing Trusses with Rollforming Services Axxis 150mm Steel Framing Walls and Tophat Purlins.

Armed with Hamish’s original design and the site measurements from Mike of Builders FX, our Detailer Matt was able to generate panels that were easy to freight and handle and that fitted into place with ease. Leaving no waste on-site or unnecessary rework.


If you are interested in working with us on your next project give us a call, we are more than happy to work through a design with you. Engineers like Hamish of Mac Consultants are able to utilise our span tables in conjunction with the NASH Standard Part 2 for Steel Framing to achieve results as you see here.


Mike the Builder was more than happy with the outcome, everything fitted together perfectly and was easy to manage on-site.
