The British star architect Zaha Hadid has chosen glass fibre reinforced concrete from the Austrian company Rieder to envelope the 275 meters long „Zaragoza Bridge Pavilion“, the new symbol of the Expo 2008 in the northern Spanish Zaragoza: she has covered the outer skin of the building with 29.000 triangles in different grey shades out of fibreC. The new bridge across the river Ebro is entrance to the Expo area and at the same time multi-level exhibition area.
Design – Inspired by Nature
Furthermore the bridge figures a symbolic building, since the Expo slogan “Water and Sustainable Development” was translated into the design und the material of the construction. The pavilion bridge is slightly curved and its gently flowing form is based on the natural conditions of water. The new Zaragoza Bridge Pavilion is composed of four elements, which overlap each other like petals and form a diamond in the cross section. Inspired by the variety of nature, the main pavilion spans the Ebro River and opens up like a gladiola blossom. On the bank of the EXPO-area, the “aesthetic and emotional” bridge for pedestrians offers three different exits.
For the envelope of the pavilion, Zaha Hadid chose triangular panels made of glass fibre reinforced concrete – fibreC. A sophisticated pattern out of 29.000 elements in different grey shades causes an effect like shiny fish scales and shimmers in the sunshine. Due to its dimensional effect, the fibreC triangles imbue the outer skin of the pavilion with life, reflecting the glittering and varied facets if the water.
fibreC – A Sustainable Material
Apart from its design and visual impact, Zaha Hadid’s idea could stand up to 40 competitors at the jury – not least due to the sustainability of the used materials like fibreC. “The composition of fibreC out of degradable, purely mineral raw materials entirely complies with the current trend of natural, environmentally-friendly and sustainable materials“, says CEO Wolfgang Rieder. Apposite to the Expo-Theme “Sustainability”, Rieder has been certified in May according to DIN EN ISO 14.001. This international approved environmental management certificate confirms the commitment to sustainability at Rieder. With this „organic approach“, Zaha Hadid’s design of the bridge as well as the use of the material fibreC fit with the EXPO theme „Water and Sustainable Development“. The innovative material fibreC enables big creative freedom in terms of mouldability, colour and processing.
