O'Donnell & Naccarato provided structural engineering services for the new state-of-the-art, 12-story medical office building. O'Donnell & Naccarato designed the 153,000 SF steel-framed tower to be built atop an existing 7-story, post-tensioned concrete parking garage. The project required significant column transferring to accommodate the existing parking garage column grid while maintaining proper spacing for the use above. The new elevator and stair cores through the existing parking garage required intricate retrofit of the existing post-tensioned floor system. The project is pursuing LEED certification.
