That is a picture (click to enlarge) of a Guastavino vault floor supported on a Guastavino arch “girder.” Guastavino construction – thin-shell vaults made from layered tiles – was Catalan vaulting adapted to American practice. It’s famous for long spans and impressive structures.

At this building, it’s used for all of the interior floors, and where two spans were necessary, a thin-shell arch was used between masonry piers rather than a steel girder between steel columns.IMG_1004
