Roading and tunnelling: engineering for the Shakey Isles

New Zealand is a land of very active geology where roading developments cut through mountains, valleys and coastal terrain.

RDCL provide the right people - geologists, geophysicists and geotechnical engineers - and an impressive set of tools, to allow designers to build the right road, tunnel or bridge.


RDCL have been involved in Transmission Gully, Central Interceptor Project, Ara Tūhono - Pūhoi to Wellsford Road of National Significance and many other developments, providing in-situ testing to ensure ground conditions are understood by our engineering clients. RDCL has the tools others do not, so we come equipped to get the answers engineers need.
