We have worked intensively in the pre-construction phase of some major EFW Slipformed projects. We have developed key Slipform construction strategies for all eventualities of the construction phase.

 

  • Core consisted of 2498m3 of concrete & 650t of reinforcement.
  • 170lnm of wall plus 6 free standing columns to 20m in height were constructed within the main slipform.
  • 187no. Embed plates were cast, weights varies between 15kg & 142kg.
  • 10 sets of 12nr holding down bolts 1.5m long were cast to take following steelwork.
  • 4no. Corbels were constructed using slipform formwork and hung on the wall TW.
  • Slipform formwork was pre-assembled off site and delivered as required to accelerate build time.
  • Programme: 16 days to complete the build on-site, 14no 24h shifts to place concrete 200mm layers & 10 days to dismantle & demobilize from site.
