CITY RAIL LINK - C1
City Rail Link
Mini-piling, Jet Grouting, Low Head room, Cutter Dwall
C1 is one of the first enabling works contracts to be let as part of the wider City Rail Link infrastructure project that will see a new underground rail line installed in central Auckland. The contract focused on the works in and around the existing Britomart station.
March Construction in joint venture with our global sister company Soletanche Bachy international, undertook the geotechnical foundations element of the project. This involved the initial underpinning and stabilising of the Britomart building before the construction of a trench box under it. The scheme required numerous different techniques and solutions be undertaken such as low head room Dwall, jet grouting, and mini-piling.
