Warragamba Dam NSW Hatch Design by Konceptual

Challenge

Integrate a 2 tonne pedestal crane into an existing waffle-slab turbine floor of unknown capacity without interrupting live dam operations.

Solution

We built a plate-and-shell FEA model to verify the slab’s load-bearing performance, designed a 1 t concrete hatch with embedded lifting hooks, and specified local reinforcement and a staged install to keep the turbine room online.

Key Highlights

  • Continuous operation ensured zero downtime
  • Slab capacity confirmed for 2 tonne crane with <1 mm peak deflection
  • Hatch integration matched crane pick-points for seamless lifts
  • Targeted reinforcement cut steel use by ~20%
