Istanbul/Turkey

Atatürk Olympic Stadium

Atatürk Olympic Stadium located in Ikitelli, a district in the western outskirts of Istanbul, is the largest-capacity stadium of Turkey. The stadium takes its name from Mustafa Kemal Atatürk. Its construction began in 1999 and was completed in 2002. It was built for Turkey's failed bid for the 2008 Olympic Games that were ultimately awarded to Beijing. It cost about 133 million Euro. With its 80.000, all-seater, capacity and Olympic size, it was granted the "5-star sports complex" title by the UEFA in 2004, enabling it to host the finals of UEFA events.

Design and construction
Istanbul Atatürk Olympic Stadium, an assertive project to support the City’s Olympic goal, has been built with the highest international safety and construction standards. The Stadium’s two State of the Art Steel Roofs (2.800 t and 1.300 t) were produced by Tekfen’s Steel Structure Fabrication Plant at Ceyhan, Adana. The west roof, designed in the form of a crescent and principally composed of a 1.000 t main beam called mega-truss, is supported by two reinforced concrete shafts with 196 m span.

With its 134 entrances and 148 exit gates, the Olympic Stadium allows 80.000 to evacuate within 7,5 minutes, in case of any emergency. Two annex (warm up / training) fields are connected directly to the Olympic Stadium with an underground tunnel.

The Olympic Stadium’s superior technical infrastructure and design ensure perfect visibility from all stands; a homogeneous sound level (102 decibels) with the most modern speaker systems and 1.400 lux illumination at every single point.

Facts
Steel Structures: 5,400 t
Roofing & Cladding: 52,000 m2
Due to the material properties including resistance against aging and its sustainability – which are ideal conditions for a long term sealing with economical attractivity – 26.000 qm of surface was sealed with thermoplastic roofing membranes made of PVC-P.
