| World's tallest building formed with MEVA formwork  The Burj Dubai will be the highest building ever erected by mankind. How high is being kept a competitive secret - but it will be higher than 8900 m (2,625 ft). The wind forces at such extreme heights are awesome: the antenna at the top of the Burj is designed for a deflection of +/- 12 m. The biggest share of the on-site concrete works is dedicated to the slabs with a total surface of 224,808 m² for 532 slabs on 153 floor levels – an area as big as 33 soccer fields. MEVA supplies a complete formwork solution with its slab formwork system MevaDec. Only 3,000 m² of MevaDec slab formwork are required for the project. Concrete is poured at night only to avoid the daytime heat. Every 3 days a complete slab is finished. The MevaDec drop head with quick-lowering system allows stripping the panels and beams while the props remain as reshoring. The low weight allows the panels to be transferred to the next floor level by hand. No crane is needed. There is no plywood that cracks under hundreds of re-uses: The MevaDec has an allplastic, 100% wood-free facing that needed no replacing. No down-times and no disruptions! This saved millions in building delays during 28 months of building. In fact, the slabs were completed in March 2008 about ten days ahead of schedule. write your comments about the article :: © 2008 Construction News :: home page |
