The module dimensions adopted, naturally lend themselves to office subdivisions and combinations to suit varying sizes and requirements of suites. Locations of light fittings (which in- corporate air conditioning out-lets) and sprinklers are such that they suit practically any office arrangement without relocation and result there- fore in great flexibility.
Three Lift Banks
The lift service is in three separate "banks", low. medium and high rise groups, of five lifts each serve ap- proximately a third of the building floors. All lifts operate from the building's main lobby at George Street with two express lifts serving the top two floors also stopping on the lower plaza shopping arcade level.
The top floor of the building will contain a public observation terrace on two levels so that visitors can en- joy the superb view of Sydney. Be- low it is the revolving "Top of the Tower" restaurant. The dining floor. on two levels (so that from every table one can see the view), will re- volve completely once every hour.
