Fully frameless revolving doors from Record’s Diamond Series were selected to replace the existing 20-year-old canopy style revolving doors during the lobby upgrade at One Farrer Place in Sydney.
Designed by architects Johnson Pilton Walker, the upgrade presented a number of unique challenges. Firstly, the size and complexity of the surrounding cable truss supported frameless glass assembly meant this could not be modified; however, the small size of the existing doors would not be sufficient for the current occupancy demands of the two commercial office towers.
Therefore, the new revolving doors needed to be offset completely within the building to maximise their diameter, and therefore, the capacity as much as possible.
To achieve this, Record Doors designed the revolving doors with extended glass roofs with a square front face to align with the frameless glass above, along with new glass return glazing, one side of which pivoted to allow for cleaning access between the two doors.
Secondly, with a glass roof design the drive motors needed to be mounted to the underside of the existing structural slab. The builder, FDC needed to core hole through this slab to allow the drive shaft to pass through as well as relocate the existing building services directly below the slab that would have otherwise interfered with the mounting of the drive system.
In addition to the four revolving doors on both sides of the lobby foyer, Record also supplied and installed four DFA 127 automatic swing door operators that, like the revolving door drive motor, were mounted to the underside of the suspended slab to allow for the most frameless entrance design possible.
