The Sydney Opera House car park is another engineering marvel in keeping with the building. The car park layout is an intertwined double helix configuration, which required a unique radio design and construction method. The site Radio Engineer and Project Engineer worked closely together through the design and installation phase to ensure the site met RF (Radio Frequency) objectives at integration. The installation had to be carefully coordinated with building management to ensure there was no interruption to the operation of this bustling car park or the Opera House itself.
