Networking at Living Coasts
Published: Feb 22, 2016The characteristic aviary net at Living Coasts is under constant punishment from the elements. This blog provides information about its ongoing maintenance.
Torquay’s coastal zoo and aquarium is well known for its characteristic aviary net. The outline of the aviary, which in places measures up to 22 metres in height, can be seen from miles around. The net’s surface area is almost 1.4 acres and encloses 1.8 million cubic feet of free flight space for Living Coasts’ collection of birds such as Inca terns, pied avocets, oyster catchers, guillemots and tufted puffins.
Living Coasts boasts an idyllic location on the shores of Torquay’s harbour. However, the downside is that the net has to face storms head-on; and even the sun’s ultra violet rays can weaken the netting’s fibres.
There is a rolling programme to replace sections of net. Bristol based company Base Structures, who specialise in tensile fabric structures, have just completed the latest phase, replacing seven panels of netting surrounding the Auk Cliff exhibit.
Qualified rope access technicians have to climb the masts, haul the new panels up on pulleys and stitch them into place. This time their work was hampered by ferocious winter storms and winds of up to 50 mph. The Base team will be returning in November 2016 to refresh another part of the aviary.
