Colleagues, we are only a few hundred votes behind.
Hiway GeoStabilization (HGS) contributed to a finalist project in the Institution of Civil Engineers 200’s Favorite Project contest. As part of the competition, industry professionals are asked to vote for the winner and voting closes at 4AM NZT Saturday, September 29. Please take a minute to vote for “Moving mountains to reconnect communities (Kaikoura, New Zealand).”
The project involved the restoration of the main transportation artery links on the South Island of New Zealand following the 7.8 Magnitude Kaikoura Earthquake of November 2016. HGS led a major part of this NZ$1.1 Billion effort by stabilizing the rock faces at Ohau Point with a combination of rock scaling, rock bolts, and high-strength wire mesh and ring nets. Their work is illustrated in this video and this webpage.
The site was classified a “Class D –Deep or Soft soil site” as defined in the New Zealand Standard NZS 1170.5:2004, with soils comprising Hinuera Sands and Silts up to 10m thick overlying Puketoka Clays. The upper sands and silts were deemed liquefiable and the new bridge structure needed suitable ground improvement measures incorporated into its foundation design.
