IPWEAQ CQ BRANCH CONFERENCE 6

THE NEED

slide-7
SLIDE 7
  • More robust replacement – not like for like
  • Minimal impact on tidal area
  • Close consideration of constructability (fabricate / transport / erect)
  • Safety in Design for the whole life-cycle
  • All pointed to a box girder truss bridge

IPWEAQ CQ BRANCH CONFERENCE 7

THE APPROACH

slide-8
SLIDE 8
  • Tides & the elements (corrosion protection)
  • High flowrate / velocities in storm conditions
  • Floating debris impact & debris mat loading
  • Thermal expansion of truss elements (fixed / roller) & PE pipe
  • Pipe material selection & connections
  • Abutment load bearing and overturning considerations
  • Crane outrigger loading
  • Vandalism prevention / safety
  • Satisfying Council / DILGP / Aurizon requirements
  • Constructability (civil & structural)
