| Universal Modular/GE formwork  A demanding building construction for a bank using long-lasting PASCHAL Modular/GE wall formwork. Many a modern building is planned in a way that exceeds the limits of conventional construction techniques or the load-bearing capacities of standard construction materials. Balanced overall-designs which apply the expertise of all participating parties, including formwork planners, help in meeting these requirements and keep additional costs within limits. The upcoming town of Wilferdingen lies between the cities of Karlsruhe and Pforzheim. A bank building was designated for large building extensions. As in previous years, the Denning Construction company received the order for this job, the same firm that erected the original building back in 1989.Excavation work lasted from February to March 2011. Excavation extended to a depth of 4.0 meters. Difficult soil conditions and the high level of ground water made things difficult. 8 wells had to be built as drainage shafts and 25 geo-thermal drill shafts totalling 2.900 meters in length were sunk. The latter are used in the all-year-round air-conditioning of the building structure while the former serve as a means of keeping soil-sealing expenses down. Shell construction work was carried out from April to August 2011. Despite the outer inconspicuous architectural structure of the building, there were considerable static and technical demands which could not have been solved with traditional methods of construction. To meet this challenge it was necessary to create a sophisticated overall concept. Large parts of the building have a sub-basement allowing the construction of a 0.6 meter thick base plate plus thermal insulation. The remainder was shored up with strip foundations including thermal insulation. The company owned Modular Universal Formwork was used for the retraction work on the foundations which used 1.700 cubic meters of concrete C30/37 and 260 tons of steel (70% round steel bars, 30 % reinforcement meshes). The basement lies at ground water level and was constructed as a water-proofed concrete tank. write your comments about the article :: © 2012 Construction News :: home page |
