This art installation was designed by artist Juan Pablo Pinto and Lachlan Brown from Cave Urban, and features two towering steel sculptures that represent the Parramatta River’s history. The sculptures, constructed from recycled steel calibration samples from Infrabuild Steel Mill, depict the river’s shape and geology through layered sedimentary patterns. The challenge for our engineers was to ensure the stability and visual impact of these massive steel structures within the aquatic center’s framework. This involved careful analysis of weight distribution to meet safety regulations and an understanding of the long term effects of the environment on the exposed steel. Close collaboration with the artist and designer was necessary to accurately translate the concept onto the steel surfaces, balancing structural integrity with aesthetic considerations, down to the size and locations of welds.
