In mid-2011, it was announced that the 'Well Connected' consortium led by Fletcher Construction had won the tender, for $1.3 billion. The consortium also included McConnell Dowell Obayashi Corporation, PB New Zealand, Beca Infrastructure and Tonkin + Taylor, as well as five sub-alliance partners and contractors: SICE, Wilson Tunnelling, Downer EDI Works, Boffa Miskell and Warren and Mahoney. The consortium worked on the alliance model, in which financial risks and incentives are shared among all partners.
