Very Deep Piling for The Highrise Zalmhaven I In Rotterdam (NL)-Video

Video Transcription

Video Summary

The presentation describes the foundation design and construction of Zalmhaven, a 215-meter residential tower in central Rotterdam. The city’s soft clay and peat layers, combined with compressible deeper strata, make settlement a major concern; conventional foundations could cause excessive movement and affect neighboring buildings. The project used 162 drilled soil-displacement piles, grout-injected and extended to about 65 meters to reach deeper sand. Engineers modeled individual piles and the full pile group using finite-element analysis, including soil behavior and long-term consolidation over 20,000 days. Predicted settlements were checked against measurements taken at the foundation slab’s four corners during construction, with results broadly matching expectations. The talk also explained the specialized installation process, including connecting pile segments on site and continuously monitoring drilling and grout flow. The project demonstrates how deep piles and detailed analysis can enable high-rise construction in challenging ground conditions, with future projects expected to require piles as deep as 80 meters.
