Project Description

Severe flooding in 2021 resulted in the Waihopai Valley Bridge being washed away, removing a key piece of rural infrastructure. Egypt Civil Construction were appointed to build a replacement bridge, comprising 6 spans over a rapidly flowing mountain river.

Project Challenges

To build the hammerhead headstocks safely and efficiently, without reliance on scaffold towers in the flood plain, it was necessary to develop a modular suspended falsework system and working platform that could be supported from each single pier.

Added Value

RBG designed clamped falsework, sequentially fixed to each pier using pre-tensioned rods, on top of which modular steelwork and timber framing afforded a working platform and supported headstock formwork. Along with detailed structural design, RBG developed and documented a full installation, dismantling and lifting sequence, with safe working facilitated by considered detailing
