The dome shape of the roof, by design, causes both vertical and horizontal reactions or forces on the buildings walls and monoliths. In order to make Max Abramovitz design a reality, a relatively new post-tensioning technique was required. The post-tensioning techniques required for the construction of the Assembly hall were first developed for Titan missile base construction. Felmley-Dickerson Co sub-contracted Preload Co. of New York City to post-tension a concrete ring girder around the perimeter of the dome. Preload Co. borrowed a special horizontal-wheeled tractor from the missile silo work to wind the steel wire around the dome. The wrapping machine required some slight modifications for this project.
