News – 15/08/2016 Bigger Doors Are Better Doors At Barangaroo
For the three commercial towers at Sydney's Barangaroo only one revolving door has been used, the record Diamond Series.
Record Automatic Doors, and the Australian door company it acquired in 2014, AGP Door Systems, has established a reputation over the last 25 years in Australia for pushing the boundaries of revolving door design to meet the architectural requirements of the client and provide impressive entrance systems of commercial buildings. This is no more evident than the revolving doors used at the three commercial towers of Barangaroo South in Sydney.
We are currently two thirds the way through installing 21 of our glass roof Diamond Series revolving doors with Towers 2 and 3 already completed and Tower 1 to be finished later this year.
During the design and development process significant care and planning went into ensuring the size of the main entry revolving doors would be able to meet the expected pedestrian traffic flows of the estimated 23,000 office workers to use the three towers. A traffic study was undertaken which concluded that 4000mm diameter would be required to allow large groups of people to use these entrances quickly and safely.
For the recently opened International Towers 3, the concept of bigger revolving doors was taken a step further. For the south lobby entrance the design of the surrounding podium glazing and awning required revolving doors of a much greater height and Record was able to offer Diamond glass roof revolving doors at 4000mm diameter x 3900mm high, a size previously unheard of for a frameless glass revolving door. The result is an airlock entrance that is on the one hand bold and imposing, yet also complementary to the stylings of the lobby façade and adjacent features.
The importance of a revolving door in regards to maintaining an airlock and reducing the impact on a buildings HVAC system cannot be overstated however for many people, a revolving door is perceived as a nuisance and will be ignored in faviour of adjacent swing doors. In many instances this perception is derived from a door that is too small the size of a revolving door is of critical importance to sure it when designing a building entrance. and at record Automatic Doors we can provide expert advice and assistance in incorporating a revolving door into your foyer entrance.
At Record Australia we strongly believe our Australian manufactured revolving doors are the best in the world. They have been designed with quality, not cost savings, in mind. They don’t come in a box, they are architecturally styled, without the rubber seals, exposed edges, or visible fixings of alternatives. Our doors will complement a facade, add gravitas to a entrance, and create a striking first impression.

The Diamond Series revolving is the result of record’s experience in the areas of revolving door technology and structural glass engineering. This door was developed in response to popular demand for the most frameless revolving door possible. Its clean and uncluttered appearance belies the complication of its design.
For International Towers 3 at Barangaroo, record Automatic Doors was responsible for a total of 7 revolving doors, including 4 of the largest Diamond Series doors ever built at 4000mm diameter x 3900mm high, installed to the South Lobby
The scale of these doors provides an imposing architectural feature of the podium lobby works and complements the height of the main entry cantilevered glass awning. A smaller Diamond door was also provided to the cafe entry.
Due to the size and weight of the carousel, these doors could only be provided with a 3 wing carousel however the larger segment spaces this design provides results in a spacious and safe revolving door entrance able to accommodate the expected heavy traffic flows.
To the North Lobby entrance, record installed two Diamond Series revolving doors, 4000mm diameter x 3000mm high. The full frameless glass design of the Diamond Series, made possible by the glass sidewalls being designed to support the dead load of the glass roof, allows the doors to complement the frameless appearance of the striking surrounding glass assembly and atrium.
For these doors the drive motors were mounted in a pit within the floor slab, with removable access panels in the floor for general service and maintenance. A custom stainless steel floor ring was developed to not only provide a clear separation of internal and external floor finishes, as well as a glazing channel for the frameless glass sidewalls, but also to house a recessed LED light strip feature in the floor. The doors are clad in linished stainless steel to match the surrounding finishes and the press to slow buttons and mode key switches are mounted on free standing stainless steel bollards at both entries.
For disabled and after hours access, record also installed 16 of its infloor mounted C 127 automatic swing door operators to the main lobby entries, retail tenancies and food court areas.
The C 127 empowers building designers with the ability to provide automatic swing door entries, necessary to meet disabled access requirements, in addition to emergency egress and after hours access requirements, without the need for visible transoms above the swing door that can detract from the architecturally designed appearance of the entries.
For the North Lobby doors, this allowed for clean frameless glass highlights above the doors and at the South Lobby a stainless steel soffit was designed without any visible linkage arms from the operator to the door, or access panels that could cheapen the appearance.
All doors are activated by push buttons on either side and locked via electric strikes mounted at the door jambs. Internal lever handles also allow the doors to be opened manually and service access to the C 127 operator is via special removable stone inlay panels to provide a seamless floor design.
