Special features:
  • Addition of three storeys to a structural concept that was originally designed for two additional storeys
  • Preliminary investigations showed that the normative increase in wind loads in combination with an additional storey level pushed the original structural concept to its static limits
  • Application of a wind technology report and spatial modeling of the supporting structure
  • Activation of the system and load reserves without significant intervention in the lower load-bearing structures and foundation elements of the deep foundation
  • To maintain the existing qualities of sound and thermal insulation, construction of the upper storey levels in classic solid construction method
  • Implementation of the construction measure during ongoing operations
