Design Exploration Services

As part of the design exploration process, CAST CONNEX led a node shaping study which, through the use of both computational and 3D-printed models, demonstrated how various nodal forms impacted the geometric appearance of the diagrid. Diverging somewhat from their original visualizations, the design team ultimately opted for a nodal form that emphasized a vertical articulation of the diagrid’s framing.

The collars are the key linkage between the existing reinforced concrete structure and the new diaphragm and damper system. CAST CONNEX improved upon the original casting design through the addition of various design features and production processes that ultimately improved casting quality and tolerances, thereby resulting in simplification of subsequent fabrication and installation of the collars and associated structural steel framing.

In design exploration prior to award of contract, CAST CONNEX worked with the designers to develop the unique geometric form of the base node taking into account project team concerns for constructability, aesthetics, coating type and durability. Through coordination with the fire protection engineer, the casting wall thickness was increased beyond that required for structural purpose to ensure the component will provide a 2-hour fire resistance rating without the need for intumescent coating of the casting.
