A pioneer in the revitalisation of Brisbane鈥檚 Queens Wharf district, 1 William Street, is the iconic structure transforming the city鈥檚 skyline and government precinct.
Of the 74,853m虏 of lettable area, developer CBUS has allocated 60,000m虏 for the Queensland Public Service, with the government lease guaranteed for a 15-year term. With the capacity and function of the upper floors yet to be determined, Brookfield Multiplex and Axis Plumbing appointed Geberit to manage the challenge of ‘future proofing’ the building.
鈥淔or us, quality was everything 鈥� we needed a single source of supply that we could confidently rely on to buffer us against these undeterminable factors and was flexible enough to support whatever went in on those floors,鈥� says Axis Plumbing general manager Bruce McIntosh.
鈥淕eberit offered us an all-round technical solution that cannot be found elsewhere on the market; utilising their products and team meant we were able to satisfy our client鈥檚 needs and expedite the bureaucratic consultation, documentation and approval processes.鈥�
Half the diameter of similar pipes, Pluvia solved the challenges presented the awning design and the tight service duct. Freeing up space in the service rises, it also offers a higher discharge capacity (up 100l/s).
鈥淭he efficiency and compact nature of Geberit鈥檚 Sovent and HDPE drainage systems gave us greater flexibility and saw us reduce the amount of discharge stacks from ten to six, which translates to significant cost reductions,鈥� says McIntosh.
Beyond the economic benefits, Geberit鈥檚 ability to extend branch lines up to 10m unvented means that even with the reduced number of stacks the system was able to cover the same amount of floor space and maintain scope for future connections.
Having spent over 50 years developing this technology, Geberit continues to innovate and improve upon its Sovent fitting. Boasting a higher rate of 12L/s and with a smaller pipe dimension of 110 mm, the new High Flow embodies the advances of modern construction methodology and is a market leader. The multi-junction fitting maintains consistency in velocity speed while being compact in size and is a 4L/s improvement on the competition. This extra capacity translates in to nearly double the number of possible fixtures. With capacity for 900 fixture units as opposed to the 500 offered by other models, Geberit and Axis were able to plan for any contingency presented by the unknown upper floors.
鈥淗aving created the patent for this product, Geberit had the knowledge and technology to alter their products to suit this specific project,鈥� says McIntosh. Aligning Geberit鈥檚 Sovent Manual with the Australian Standard AS3500, Axis worked in collaboration with Geberit鈥檚 design engineers to push the product beyond its preconceived limit. 鈥淲e had this rare opportunity to co-create and tailor a fully coordinated solution to go to construction with that complied with the challenging parameters set out by the William Street design 鈥� an opportunity that only Geberit could offer us.鈥�
