Recap:
DHML is part of the successful team selected by Christchurch City Council to reopen the Sumner to Lyttleton Road near Christchurch.
Badly affected by the 2010 and 2011 earthquakes this important link between Christchurch City and Lyttleton Port has remained closed ever since.
DHML is working with McConnell Dowell, Beca, Geovert, Orica and Inline Drilling, to design and complete geohazard risk mitigation works to facilitate opening the road. Works include scaling and rock bolting of high bluffs, excavation of a specifically engineered 400m long and 15m wide catch-bench in rock below the bluffs, and the foundations for two substantial bunds.
