Key activities during the preconstruction phase include collaborating with the design team, performing transparent open-book cost estimating, developing construction schedules, and identifying opportunities for value engineering and risk mitigation. The GC/CM contractor will also be responsible for developing subcontracting plans, managing permitting and approvals, and coordinating real property acquisition. The project is subject to a consent decree deadline of December 31, 2034, for construction completion.
