Boomerang Tower is a 38-storey, 230 apartment residential tower in Sydney. It is positioned on the iconic Olympic Boulevard with spectacular city and parkland views and near the Aquatic Centre and Sydney Olympic Park. It has a 6 green star rating, is designed in the shape of a boomerang to achieve optimum solar input, has a landscaped podium rooftop and a variety of outdoor spaces and communal gardens. With tight deadlines, innovative construction techniques and materials were vital. Boomerang Tower was completed in December 2019 and won a 2020 NSW Architecture Award.
Pipe Infrastructure Capabilities
A development with tight deadlines and demand for innovative structural solutions requires significant supporting infrastructure, including service piping. Allmach’s Surepress 316L stainless steel press-fit pipe and fittings have been used for all the gas, hot-water, and cold-water pipes and non-potable water pipes. Allmach supplied *an impressive 15,000m of stainless steel pipe, with accompanying press-fit fittings and custom fabricated manifolds for this purpose*.
Challenges and Solutions
Two key piping issues needed to be addressed with the Boomerang Tower project. High pressures going through the pipework because of the height of the building and the curved-shaped building made it difficult to run pipework neatly. SurePress piping and fittings withstand high pressures, which copper piping cannot handle. Therefore, SurePress was an ideal solution. It is also easier and safer to assemble on-site since it requires no hot work permits, and QA checks were more manageable due to the press-check sleeve film and leak path O-rings. In addition, Allmach fabricated special press-fit bends in the Queensland fabrication department, so it suited the building architecture requirements.
The Boomerang plumbing contractor reported the SurePress 316L stainless steel press-fit system made the gas and water pipe installation faster, easier, and safer to install than traditional copper pipe, saving significant time and money. The contractor was pleased there was no welding required, and all fittings were crimped and easy to check.
