King County filed the lawsuit against VPFK in 2010 with claims that contractors failed to meet deadlines after two TBMs broke down hundreds of feet into the ground. VPFK — a joint venture of Vinci Construction Grands Projets, Parsons, and Frontier-Kemper Constructors — had been given a USD 212M contract to bore two Brightwater tunnels after a bidding process in 2006.
