The construction includes multiple student facility buildings that incorporate seven General Learning Areas (GLA’s), a fully functional canteen, staff room, an outdoor area and offices. The uniqueness of the building structure, together with an ever-increasing IT rich learning environment required a coordinated, patient and precise electrical services installation. JHA worked closely with the Electrical contractor GCA Electrical Australia. As part of an energy saving strategy 14kw of solar panels were installed on the roof area, as well as an energy monitoring system being implemented on the heavy usage power circuits. This system allows the school to monitor their own energy usage and to find areas where energy costs can be saved. Daylight harvesting sensors were also installed, these sensors automatically adjust light levels within the building depending on the daylight levels outside.

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 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.
