When L.F. Driscoll asked us to design a 90′ high, totally enclosed negative pressure wrapped, systems scaffold tower for the front of Children’s Hospital of Philadelphia, we said “No problem”. Then they told us the scaffolding had to be completely free standing (to allow the installation of a continuous glass panel system)! So Superior’s engineers designed a 90’high scaffold with 2 attached backup towers (widening and stabilizing the base) which tied only to a roof system of concrete weights. The system was rated to handle high wind loads and provided a safe work environment with a minimum of disruption to the hospital. Our designers also developed a hinged (and wrapped) roof panel for the top of the scaffold that would allow glass panels to be flown in with a crane.
