Morris Arboretum, Out on a Limb

Out on a Limb is a 50-foot-tall, 450-foot-long steel structure that delicately weaves in and out of the tree canopy, leading visitors to intriguing destinations along the way. A primary structural challenge was designing around the trees, and in some instances, introducing the trees themselves into the structural design.

Structural touch-down points and foundations were minimized and carefully engineered so as to not disturb the tree’s root systems. CVM also worked closely with the design team and the general contractor throughout the process to coordinate site activity and remain on schedule and within budget.
