Fausto Giovannardi, one of the founders of the Italian architectural and engineering firm Studio Giovannardi e Rontini, has completed a 52-page illustrated paper on Edgardo Contini. Contini worked with John Lautner on a number of projects in the 1940s, notably the trio of Jacobsen, Polin, and Carling, all of which use the same hexagonal steel horizontal frame supported on three tapered steel trusses.
