Richard Wilsons 'Slipstream' sculpture situated in Heathrow Terminal 2 arrivals lounge. A stunning piece of art over 70 metres in length. The skin is made up of thousands of sections of aluminium cladding and literally hundreds of thousands of rivets. ProAltus provide all the access to the areas of the sculpture that could not be reached from ground level via mewps. This amounted to over 50% of the cladding install and majority of bolting to the steel frame work that secures the sculpture.
