The future of Bern railway station

Once the tunnelling had been completed, the base slab was concreted in several successive steps. Prefabricated Stremaform^® sections were used to form the construction joints, which were anchored back due to their height. This meant that the reinforcement could be continued without interruption and a force-fit connection could be created through the roughness of the joint. When using Stremaform^® as permanent formwork, no striking of the formwork is necessary, which means a smooth construction process.

A special detail on the construction site was the recess for a pump sump, which was only excavated later: An elliptical Stremaform^® formwork simultaneously served as a finish for later excavation work and as a force-fit connection for the subsequent concreting of the walls of the pump sump.
