PERI offered us the best technical design and the most cost-effective solution. What we were able to achieve with the formwork carriage was more than satisfying. This helped us to pour the segments in a weekly cycle. What qualifies our formwork partner even more is the fact that the technical support was always able to provide us with the right solution in case of questions of detail.
