Benefit to customer

  • Limited tower crane time meant manual moving of DUO was a big benefit.
  • Hydraulic climbing of RCS reduced crane time requirement.

PERI helped our company to meet the programme requirements for this project.
The project required a wide variety of shoring, propping, scaffolding, suspended slab pours, shear wall pours and lift core pours. These were all designed and supplied by PERI.
The support provided by PERI to our on-site team was greatly appreciated.
