Grand entrance – Dorma NZ

First impressions matter – and it's the entry that sets the tone and character for what follows at AECOM House. The design team specified a Dorma KTC2 two-way revolving door with integral bi-parting automatic doors for the main entry on Beach Road.

To provide a sleek, contemporary aesthetic, the outer skin of the drum walls are glazed, and the door is contained within a highly polished stainless steel framework, beneath a stainless steel ceiling.

Special features of the KTC2 revolving door include bulbous rubber seals on the leading edges of each of the two wings. These incorporate pressure centres, which can detect an obstruction and ensure the doors stop revolving. Stephen Piner of Dorma NZ says the door is top hung so there is no pivot on the floor, ensuring a clean, uninterrupted circulation.

"There is also an onboard UPS, which is used in the event of a power failure or fire emergency. The system can be programmed to keep the door in a secure mode, or it can default to stay open in an egress-compliant mode. This system does away with the need for separate fire safety doors on either side. There is also a blue disability button on one side, which slows the unit down to give people time to pass through."

Dorma NZ also supplied all the automatic doors for the retail tenancies on the ground floor, and a Horizon HD10 bi-parting automatic door for the other entry on the north side of the building.
