WALTZING ALONG: It is taking less than eight months to transform the historic skyline of Vienna. On the banks of the River Danube, the 202m Millennium Tower, destined to be Europe's third highest building, is rising at a rate of two and half storeys a week. Joint venture contractor MCE-Habau has largely managed to achieve what it claims are 'world record' speeds by

de-linking the construction of the tower's core and floors. The core's 10 insitu concrete lift shafts and foyer areas have all been equipped with their own self-climbing Doka formwork. Four storeys 'behind', the composite floors are being constructed using steel cored columns filled with self-compacting concrete to support the girders around which the floor slabs are cast.
