Oroua River Stop bank Upgrade

This project for Horizons Regional Council consisted of the upgrade of almost 3km of stopbanks along the Oroua River for flood control and mitigation. It included some 50,000m3 of earthworks to reconstruct and partial relocation of 4km of stopbank on the Oroua River. Appropriate material was cut from adjacent river edge and compacted to new design profile. Stringent testing was undertaken to ensure contract specifications were achieved. The contract required site to be re-top-soiled and a specified grass cover was achieved on completion.
