Advanced Works CM/GC Phase 1 awarded to Flatiron-Herzog, a SGL Joint Venture, on the Board’s consent calendar February 2025; preconstruction is under way and Metro is conducting underground utility investigations in South Gate to support future engineering design. No competitive tender is open for the main build, and that is the delivery model rather than a pause: under construction manager/general contractor the contractor is already on board and prices the construction phases by negotiation with Metro inside the authorised preconstruction budget.
