The entire signage system was redesigned and redeveloped in line with the scope of the international tender for the 5th Expansion Project of Zurich Airport. The client demanded energy efficiency, low maintenance requirements, reliability and cost-effectiveness for the entire lifecycle. Rapid tool-free design conversion was particularly important, as constant signaling adjustments had already been required during the construction phase . In collaboration with the industrial design department of Nicholas Grimshaw & Partners, London, BURRI developed a slim-line, variable and perfectly coordinated global system. BURRI has developed, manufactured and locally installed innovative solutions. New design standards determined the minimum overall depth and consistent illumination still required. The graphic design is by Designalltag Zurich.
