Unique Attributes

  • Structural demolition of two lane bridge above Queensland’s busiest road – the M1 Motorway, including night works to accommodate road closures
  • Cut and lift methodology designed alongside safe removal of asbestos sheeting throughout structure

  • Installation of scaffold tower to carry weight of structure once bridge cut in half

Key Challenges

  • Design and implementation of strict asbestos controls – gutter systems to capture slurry; placement of bins to capture core holes; core hole protection flanges for safe lifts; protective L-angles installed to protect edges; and onsite hygienist and sign offs prior to reopening motorway
  • Restricted works timeframe – 5 hours per shift – to minimise impact on motorway and neighbouring residents
