On 23rd March 2010 the first fragment of the National Stadium elevation (120m²) was installed on level +1 at Wybrzeże Szczecińskie Street.
The installed fragment consists of panels of anthracite (greyish-black), non-reflective glass and transparent windows of the office area. Apart from their aesthetic qualities, the windows are very durable and categorized as safe glass. The total elevation surface of the Warsaw National Stadium is 20,000 m².
The work will be checked and assessed by the construction site inspectors from the NCS (National Sport Centre).
