Kaukapakapa, Auckland

The KiwiRail Bridge 100 in Kaukapakapa spans over a farm road. The bridge structure consists of precast concrete segments which sit on beams connected to abutments and piers.

Project Requirements

The design required a watertight strong bond between the precast concrete segments that would be able to handle climate conditions as well as the heavy vibration from the trains travelling over the structure.

Challenges

When the segments where positioned against each other, there needed to be good lubrication against the segments to get them into perfect position.
