Key Project Details

Description

Client

Downer New Zealand Limited
 

Contractor

Downer New Zealand for Bridge Construction
Eastbridge for Temporary Works Fabrication
 

Duration

Temporary works design was initiated in 2014 in parallel with the permanent works design (by AECOM). Final design and detailing was completed in 2016. 

Downer Construction was contracted by KiwiRail to replace 7 bridges near Taumarunui on the North Island Main Trunk Line. The replacement design for Bridge 207 was a steel-concrete composite superstructure comprising three simply supported spans. A launch methodology was proposed by Downer to avoid steelwork assembly at height and staging platforms within the river channel.

 

Novare were engaged by Downer to provide temporary works design and construction supervision, for works associated with the bridge launch including:

  • Methodology development in collaboration with Downer
  • Arrangement and setout of launch pit, to minimise embankment excavation and retaining requirements
  • Design checks for the steel girders during launch stages, including design and detailing of temporary diaphragm and lateral bracing elements.
  • Design of temporary splices to form a continuous superstructure during launching
  • Design of launch nose including hydraulic ram setout for lifting the leading edge onto roller supports
  • Design of launch hardware, including roller supports and lateral guides on piers, and runway beams within the launch pit
  • Design of steel portal frames and jacking sills, for lifting the launched girders off the temporary rollers using jacks and then lowering onto permanent bearings.
