Previous projects

118-124 Terry Street Rozelle,Bullsbrook District High School,Gold Coast Aquatic Centre,Qantas Hub Refurbishment,34 Hunter Street Hotel,NTU Vibration Free Laboratory,Palace Cinema,Parkes and Forbes Hospital,Gosford Regional Performing Art Centre,,,,,Vibration free laboratory for Nano science technology. The laboratory is vibration isolated to achieve a maximum 10nm displacement at 2.25Hz.,The addition of four new projection rooms on-top of an existing cinema structure. The main issue was to provide enough noise insulation from external sources with Sydney’s international flight path located at the vertical of the building requiring the team to use light weight construction due to existing structural limitations.,The project involved two regional hospitals located in NSW, one being a refurbishment of a heritage building and the other a new build. The project had typical acoustic issues associated with hospital such as helicopter noise and emergency department noise. Nevertheless the main challenge was to accommodate the construction activities with an operational hospital.,WGE were successful in a design competition for this regional performing art center that included a 1000-seater auditorium and a 120-seater blackbox with ancillaries’ facility. This project is one of a kind which only occurs every 5 to 10 years in each state around Australia. The reason for the team being successful was the translation of the project brief into the project schematic design presented to the judging panel.
