The tour began at Bockenheimer Landstraße 10. From there, we could already make out from a distance the new façade elements on the lower part of the building, designed in the style of architect Sep Ruf’s original design. Before we toured the building complex, which dates from 1965, Thomas Fischer from RSP mbH explained the challenges of the project to us – challenges arising, for example, from the addition of an extra storey and the structural reinforcement work carried out over the years. After the brief introduction, we made our way up to the future roof terrace, from where we had a panoramic view of the Frankfurt skyline. On the way, we were able to examine the renovation work on the high-rise core, as well as the old shear restrengthening of the floor beams and the additional storey.

From the future roof terrace of the ParX Tower, we could already make out the second stop on our tour. The 100-metre sign on the Central Business Tower marks a milestone in this mega-project. We would like to thank OFB Projektentwicklung GmbH for the guided tour. The site tour began in the basement levels, where only traces of the complex top-down construction method remain in a few places. Passing through the restored rotunda in the reception area, we took the lift up to the 30th floor, where the students gained a direct insight into the construction process of the high-rise. Alongside the climbing formwork on the high-rise cores, the semi-prefabricated construction method using beam elements as a structural technique proved particularly fascinating. The grid-ceiling system, which was already used in the CPX Tower, is becoming increasingly attractive in modern high-rise design, as it allows both the dead load and material usage to be reduced. The excursion concluded with a light meal together.

We would like to express our gratitude for the opportunity to give our students this insight into the latest construction projects!
