Key Project Details





Fulton Hogan Civil

Project Value 

$4.2M Physical Works


Designed during 2005 and 2006.  Construction commenced mid 2006 and was completed in February 2007.


Received at the 2007 New Zealand Engineering Excellence Awards:
  • Roading & Transport Award
  • Building & Construction Award
Pier 7 of the Makatote Viaduct required underpinning in order to eliminate the risk of collapse due to river scour, bank instability and seismic overloading.  

Novare Design was engaged to seismically assess the existing viaduct before designing the new underpinning structure. 

This structure required the installation of two large diameter bored piles and a 3m deep x 35m long post tensioned concrete cross beam, to transfer the load from the existing tower legs. We were able to ensure that the longitudinal stability of the pier is maintained by securing this cross beam to surrounding ground beams.

The physical works element of the project was very challenging. Fulton Hogan were tested by extreme weather conditions, access issues and strict environmental constraints due to the adjacent national park. The viaduct also remained fully functional to rail traffic throughout the duration of the project.  

Prior to project completion, Pier 7 was one of KiwiRail's high structural risks on the main trunk railway line. However, successfully completed, award winning project, has eliminated this risk and prolonged the life of the viaduct.
