The carving and installation of such large high-relief sculptures was a daunting artistic and technical challenge. Váró carved three sets of smaller angels in preparation for work on the actual sculptures. Limestone for the works was quarried near Austin, Texas, and transported to Irvine, California, where Váró carved the works in large numbered blocks. The delicate carving of the wings was done in Fort Worth.
Engineers from Curtain Wall Design calculated the exact dimensions needed for each block and designed lifting devices for each. A crew of ironworkers and stonemasons installed the angels under Váró's supervision. Steel plates were embedded in the concrete walls to support the angels, and each carved block is permanently attached to a corresponding plate so that no block rests on the one below. This design transfers the weight of the sculpture to the building.
Informal photographs by Váró and others record the creation of the angels from quarrying of the limestone through the initial carving of the blocks. Rodger Mallison recorded the installation process almost daily. The result is a superb photographic chronicle of a major artistic project.
