Excellence in Engineering

The PENN 2 office building needed more inviting public spaces, improved office facilities, modern amenities, and updated aesthetics. The solution: A 75-ft by 450-ft addition to the fourth through 10th floors that hovers above the sidewalk on dramatically sloped columns configured around an existing trainshed. Particularly elegant connections ensure that neither the existing structure nor the addition transfer significant lateral load to the other.
