SH1 Blue Duck Road Works
Because of the 2016 7.8 magnitude Kaikoura Earthquake, many sections of SH1 to the north of Kaikoura were realigned, protected from geohazards, or for structures like the Blue Duck retaining wall, needed remedial strengthening. This section of road curves tightly around the coast with steep cliffs on the other side leaving the only option to construct a piled retaining wall with anchors to strengthen and underpin the road sitting over fractured rock and fill.
During the planning and construction numerous program critical, commercial, and engineering risks were identified or encountered by the delivery team. Geovert added value at this point by driving
practicable solutions and with proactive plans in place to mitigate potential delays from the key challenges to the project.
