Dodson Valley / Scotia St Waterways - Nelson

Client : Nelson City Council
Head Contractor : Kūmānu

Ground Anchor Systems has been engaged by Kūmānu and Nelson City Council to complete three stream bed upgrade projects across Nelson this year. Dodson Valley and Scotia Street have been completed already with Alton Street scheduled for the end of the year.

Each site has its own challenges and varied ground conditions. Both permeated and temporary 600mm casing was used to mitigate collapsing waterlogged ground and allow for the timber poles to be installed. This was driven using our high torque drive unit.

The design includes both timber pole retaining walls and anchored shotcrete acting as scouring protection during flood events.

These projects have been completed in tight time frames and weather windows to reduce the time in the streambeds and minimise the environmental impact and disruption to local residents.
