Coogee Beach Lower Promenade
COOGEE BEACH LOWER PROMENADE
New 750sqm public amenities building on Coogee Beach lower promenade, purpose-built to cater for the growing beach crowds in Sydney’s Eastern Suburbs.
The new building combines the public amenities, the lifeguard station and surf club facilities. The separate lifeguard office, with their own changing area, has a panoramic view of the beach. The public area includes 21 toilets, 12 showers, male and female change rooms, lockers, a family change area and baby change facilities. Coogee SLSC also has space for surfboard and boat storage.
Working closely with Brewster Hjorth Architects, JHA delivered mechanical, electrical, hydraulic, high voltage and acoustic consultancy for this project for Randwick City Council.
Designing for a building that was sub-ground and also in a marine environment was the main challenge for JHA’s multidisciplinary team. All fittings, including ductwork and control panels needed to be stainless steel, light fittings needed to be sealed. Flood levels had to be studied and the effects of seawater taken into consideration.
JHA’s hydraulic team had the task of designing the council’s recycled water main system to provide water flushing to the toilets, along with mains water backup. The flushing for the toilets incorporated mains flush activation buttons instead of toilet cisterns. This required an “out of the box” design where a buffer tank system was installed in the rear corridors to house a main water “buffer” pipe to supply the required of storage for the potential simultaneous operation of the flushing valves. Additional pressure vessels were added to maintain the required pressure without the need to install large pumps, of which there was no additional electrical supply.
