  7. THE APPROACH • 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 7 IPWEAQ CQ BRANCH CONFERENCE

  8. THE DESIGN CHALLENGES • 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) 8 IPWEAQ CQ BRANCH CONFERENCE
