Customer's benefit

  • short construction time
  • fast climbing cycle sequence
  • construction sequence without interruptions
  • high material utilisation rate

Andreas Poller
Construction manager

The good experience we have had with the proven PERI systems in previous projects made us decide to again cooperate with PERI in this Naga Hammadi barrage project. All shuttering, reinforcement and pouring activities could be carried out from safe working platforms. This helped to achieve faster cycle sequences. Despite the given very short construction time we were able to reach a high quality standard.
