In this presentation from the Foundation Decarbonization Conference 2026, Dr.-Ing. Ingo Hylla explains why overdesign in special civil engineering is conservative in terms of load-bearing capacity but not conservative in terms of environmental impact. Using real-world project examples from Germany, the Netherlands, and Austria, he demonstrates how blanket classifications and overly conservative soil profiles lead to unnecessary consumption of concrete and steel. You will learn how individual load approaches per pile, governing soil profiles, and batch calculations using piledesigner.io can lead to savings of 5 to 50 percent in material and pile length, as well as how CO2 savings, costs, and construction time can be optimized together.
