Markus Kreuzer
Site Manager

Together with the PERI engineers, we designed a customized formwork carriage solution. This allowed us to concrete two sections per week – and, in spite of the ever-present passage of transit vehicles and steep longitudinal inclination, on-time completion was guaranteed. Due to the lightweight construction and hydraulic operations, the carriage could be lowered, moved forward and set up for the next cycle in less than 60 minutes.
