About this project:
The Expo Boulevard is covered by a membrane roof with a total surface of 65,000 m2, currently the largest of its kind world-wide. With a free span of almost 100m, it posed many technical challenges. The roof is supported by 19 interior and 31 exterior masts and by six funnel shaped framework shells consisting of steel and glass. It has a height of 4 m and a free projection of 8 m. These so called "sun valleys" direct natural light into the ground floor areas. (Wikipedia)
