DCI structural team designed the hybrid framing systems of cross laminated timber (CLT) ceiling/flooring, steel brace frames and beam framing, and CMU shear wall cores. The CLT floor system spans 15 feet, reducing the number of beams needed for the design. The team designed the floor systems to mitigate vibration by cantilevering steel beams over columns to add fixity, and by detailing precision connections for the steel and CLT elements. The steel system was designed with prefabricated openings to accommodate a flexible ductwork configuration which did not cover up the exposed CLT ceiling or penetrate the wood.
