Coopers FireMaster vertical fire curtains were used in a fire separation application at the Myer HQ project in Docklands, Victoria.
Designed by architect Bligh Voller Nield and developed by Bovis Lend Lease for Australian retail giant Myer, the project had CSIRO as the Fire Engineer.
A stairway had been incorporated from levels 2 to 9 of the building located at 800 Collins Street, Docklands to increase the entry of light and also support easier movement for staff between floors. Meeting rooms on levels 2, 3, 5, 6, 7 and 8 overlook the stair/atrium, breaking up the standard rectangular void and adding additional design requirements.
Since the building design required zoned smoke control and the building code didn’t allow more than two interconnected floors, the stair/atrium had to be compartmented in fire mode.
Coopers FireMaster vertical fire curtains were used to fire separate every floor from level 2 to 9 in the building, providing an FRL of -/120/-. This consisted of both single roller and multiple roller solutions.
Key objectives of the installation included ensuring that the zone pressurisation system could achieve the required minimum 20 Pa pressure differential and also allowing safe egress from the inter-tenancy stair to the fire stair.
To safely evacuate occupants from the stair, the fire curtain across the front of the stair incorporated Coopers’ dual drop function. This allows for the fire curtain to deploy to 2m above the floor and hold its position until either a local heat detector is activated or on expiry of 10 minutes. The 10-minute duration was chosen as it was the expected evacuation time for the building. All other curtains close up to the floor level on general fire alarm activation.
Coopers FireMaster fire curtains operated correctly with the zone pressurisation system; the reliability of the system was also increased by delaying its start-up by 60 seconds.
Key benefits of Coopers FireMaster vertical fire curtains include safe egress from the stair achieved by dual drop function; clear open areas around the stair increasing natural light and air flow; small compact headbox and guides incorporated easily into the building design; and ability to work perfectly with the building’s zoned smoke control system.
