Several global consulting firms have won plum contracts for a six-line, 131-station, 106-mile-long mass- transit system for Riyadh, Saudi Arabia.
Riyadh Metro Transit Consultants, a joint venture of Parsons Corp., Egis and Systra, won a $556-million contract to manage the first two packages— including lines Nos. 1, 2 and 3 and totaling 104 kilometers—for the ArRiyadh Development Authority. The team will oversee construction of the first three lines, including $10-billion and $6-billion worth of work by design-build teams led by, respectively, Bechtel and Spanish contractor Salini Impregilo (ENR 8/12 p. 17).
