The latest design-build infrastructure project on which the contractor filed a lawsuit against its designer has pitted joint venture GLX Constructors against STV Inc. for work on Boston's $2.3-billion Green Line extension.
Filed in Suffolk County Superior Court in Massachusetts, the GLX Constructors complaint says STV owes $35 million to the joint venture—made up of Fluor Enterprises Inc., The Middlesex Corp., Herzog Contracting Corp. and Balfour Beatty—for alleged errors the designer made on the 4.7-mile-long extension.
