Nile river barrage Naga Hammadi, Egypt

Nile river barrage Naga Hammadi, Egypt - The variable VARIO girder wall formwork, together with SKS climbing scaffold, formed large area transportable units.
Nile river barrage Naga Hammadi, Egypt - The 330 m long Naga Hammadi Nile river barrage consists of a power station, weir facilities and two navigation locks.
Nile river barrage Naga Hammadi, Egypt - The variable VARIO girder wall formwork, together with SKS climbing scaffold, formed large area transportable units. The intermediate piers of the weir facility were cost-effectively climbed using concreting cycle heights of up to 3.60 m.
Nile river barrage Naga Hammadi, Egypt - With concreting cycle heights of up to 3,60 m, the intermediate columns of the weir facility could be economically climbed.

Project data

Location: Naga Hammadi, Egypt

330 m long barrage with 64 MW hydropower plant, weir plant with seven weirs and two 170 m long sluices.

Requirements

  • tight construction time schedule
  • simultaneous manufacturing of single components
  • bulky, massive reinforced steel parts
  • high pouring speeds

Customer

Bilfinger Berger, VINCI, Orascom

Customer's benefit

  • short construction time
  • fast climbing cycle sequence
  • construction sequence without interruptions
  • high material utilisation rate
  • high quality standard
  • high safety during all shuttering, reinforcement and pouring activities
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.

PERI solution

  • SKS and VARIO climbing formwork solution for main and intermediate pillars
  • optimised cycle planning
  • large-size moving units
