CAST CONNEX was engaged by the Transbay Joint Powers Authority to provide its niche Engineering and Administrative Services for the Custom Designed Architecturally Exposed Structural Cast Steel Nodes required for this world-class public development project in San Francisco. The cast steel nodes required for this development are critical elements of both the gravity and lateral force resisting systems of the transit center and are of critical architectural significance for the architecturally exposed structural steel framing which wraps the entire perimeter of the building. Cast nodes also feature heavily in the building’s “Light Column” – one of the terminal’s main architectural features. The transit center’s design demands approximately 3.5-Million pounds of steel castings spread over 75 highly intricate cast node geometries ranging in weight from 6,000 to 45,000 pounds.
