Place of Worship
Vinci LLC began the assembly of the steel first by building the well-described parts of the building. The less-definite building sections gave a zone wherein steel could reside to support the dome. Vinci buddied up the implicit inner and outer arches so that they act together to resist the load of the dome. The collar steel framed into the arches. The corners of the square “crossing” part of the dome and the cylindrical barrel required more study. In masonry, this zone is called a “squinch”—Vinci translated the masonry squinch into a steel frame. This structure helped illustrate that the dome could be prefabricated. This was instrumental in Vinci’s client winning the job.
