Gyprock helps build Perth's Optus Stadium

Perth's most iconic project, Optus Stadium in Western Australia, opened its doors on the 21st of January 2018 after 36 months of construction. With a ‘fans first' approach to planning and design, the multi-purpose venue will offer an unrivalled spectator experience for a crowd of up to 60,000 (in AFL mode) with exceptional event atmosphere and cutting edge stadium design and technology.

With the planning of the project being in progress over a 10-year period, the state-of-the-art venue had long been on CSR Gyprock's radar with the aim to support the project with high performance products. There were a number of other factors that assisted the Gyprock bid to supply this project, including a reputation for innovation and technical leadership – having achieved success in delivering state and national level landmark projects including Royal Adelaide Hospital (RAH) and the Victorian Comprehensive Cancer Centre (VCCC).

Gyprock were delighted to be chosen by the wall and ceiling contractor Cubic Interiors WA to supply this project, partnering with Cubic to guide product specification and providing technical support on site. The proximity of Gyprock's factory in Welshpool, approximately 12 kilometres from the stadium construction site, was also a major catalyst in the tender process, as it helped to save freight costs and lead-time. It also allowed for Gyprock's technical team to provide on-site assistance as required.

Gyprock products including EC08 Complete, Gyptone and Rigitone, were specified for the project, with 80 semi-trailer deliveries made, transporting approximately 200,000m2 of plasterboard to the construction site.

Gyprock EC08 Complete is a premium plasterboard and made up approximately one-quarter (58,000m2) of the plasterboard product used on the project. It was specifically used in the corridors, lounges, general admission areas and food and beverage outlets due to its superior performance for mould, impact, fire, acoustic and moisture resistance.

With consideration of the volume of EC08 Complete required in the project, Gyprock's Welshpool factory responded by expanding its manufacturing capabilities to produce the premium plasterboard locally and to specific project requirements, including size of rooms, height and length of walls, and to help reduce wastage on site.

Functional acoustic performance was high on the list of requirements for the dining, conference and private entertainment areas of the stadium, but at a competitive cost of the aesthetic finish of the spaces. Balancing acoustic excellence and visual impact, the panel perforations of the Gyprock perforated plasterboard range, combined with the products acoustic fabric lining and insulation as required, deliver reduced echo and noise reverberation to create more comfortable environments.

In the corporate suites and entertainment boxes, Gyprock Gyptone 12mm Square perforated plasterboard was specified for its ability to improve sound attenuation. Providing a grid-like patterned ceiling, Gyptone's high level of aesthetic appeal was complimented by matching access panels that provide functional access to the ceiling cavity while ensuring an uninterrupted look across the surface.

Throughout the restaurants and the Victory Lounge, Gyprock Rigitone Astral perforated plasterboard was specified for its design and acoustic properties, improving sound quality and delivering a continuous pattern across the whole ceiling.

Both Gyptone and Rigitone perforated plasterboard products are lined with an acoustic fabric backing which contributes to acoustic performance, whilst concealing framework and helping to prevent dust falling through from the ceiling cavity. Another key feature is Activ'Air, a patented technology that converts formaldehyde into non-harmful inert compounds that are permanently locked in the board and cannot be released back into the air. This can reduce the concentration of formaldehyde within an environment by up to 60 per cent when installed in ceilings.

"The Optus Stadium project was Cubic's first landmark engagement with CSR Gyprock WA and we were impressed with Gyprock's proactive approach – this assisted with a successful handover several weeks ahead of schedule. This was made possible with Gyprock's fabrication being local and close to the project. I believe this will be the first of many more projects that Cubic and Gyprock will complete," says Adam Monson, State Manager, Cubic Group.
