Hamburg's 157 ha HafenCity is Europe's largest inner-city urban development project and stretches from the already completed Am Sandtorkai quarter with the Elbphilharmonie concert hall in the west to the Elbbrücken bridges, where the 245 m high Elbtower will be visible from afar in the east. Thanks to its comprehensive product portfolio, PohlCon is contributing to the success of this major construction project on the Elbe: The Elbtower by star architect David Chipperfield with 64 storeys is a real heavyweight. Building construction work began in January 2023. Completion is planned for 2025. Offices, gastronomy, culture and fitness are to find their place in the future architectural icon.
PohlCon and its H-BAU Technik brand are responsible for the entire waterproofing of the Elbtower. 2.5 km of PENTAFLEX KB® joint sheets were installed for construction joints, 750 running metres of OBS elements for predetermined crack joints in in-situ concrete walls as well as 1.25 km of PENTAFLEX ® ABS formwork elements for installation heights of up to 2 metres.
JDA punching shear reinforcements from the PohlCon brand JORDAHL were used for the reinforcement work. In the individual storeys, 65,000 punching shear reinforcements with up to 8 anchors each are planned. More than 11,600 individual dowel bars with lengths of up to almost 4 m were installed in the floor slab and 9,900 individual dowel bars with a length of 80 cm were again installed in the outer wall facing the upper harbour canal. The total length of the bolts amounts to approx. 56 km.
For the building construction, 1,800 running metres of RAPIDOBAT® formwork pipes in various diameters are used by H-BAU Technik. Thanks to the Cretcon HD coating, a very high quality concrete surface is achieved on the columns.
In the run-up to the construction work, PohlCon provided expert advice to both the planning and the executing companies.
