Adelaide Showground Solar Project, SA

Duration: April 2009 to August 2009

Value: $7.3 million

Contract type: AS 4902 Special Conditions

Summary: In partnership with Solar Shop Australia, Built Environs completed the design and installation of Australia’s then-largest roof top solar panel system for South Australia’s Royal Agricultural and Horticultural Society.

The 1 MW system, consisting of over 12,500 panels over six roof tops, provides up to 40 per cent of the Adelaide Showground’s annual power needs.

As well as the installation of the solar panels and associated systems, the project included structural upgrades to some of the buildings.

To help fast-track the project, Built Environs reviewed the loading capacity of the affected roof tops and determined that panels could be crane-loaded on to certain areas of the existing structures on pallets and distributed via trolleys on framing rails. This created a safer working environment and saved months of installation time.

Innovations brought to the project included a clip-on extrusion framing system to minimise the number of roof penetrations and maintain the existing roof warranty, custom-made-drilling rigs for each of the major roof tops and a cloth and mesh system to prevent screw swarf entering the stormwater collection system.

The client was involved with all aspects of design and approval, while the programme was adjusted daily to suit the Adelaide Showground’s constantly-changing events schedule.

As with the highly successful Goyder Pavilion construction, Built Environs completed the work in time for the opening of the Royal Adelaide Show, delivering the Adelaide Showground Solar Project two and a half months ahead of the contracted completion date.
