If you do not believe this then go to your library and find, if you can, "Candela, the Shell Builder" by Colin Faber. ![]() In this case it was Felix Candela, whose achievements both in number and quality will never be duplicated. Most great movements center around strong and charismatic leaders, and the building of shells is no exception. Labor also was having different attitudes, and construction was affected by the removal of men from the labor market. The end of the shellbuilding era, it must be noted, coincided with the Vietnam War and all of the social disruption that occurred.For monumental structures, the architectural solution is the dominate factor, not the structural material. If all the cost factors are considered, they may actually cost less. ![]() For industrial and commercial structures, it is true that unfireproofed steel structures of short span are much less expensive, but as the span increases, shells become more and more competitive. I do not accept that the reason was the exorbitant cost. I will attempt to list and explain some of these and show their effect on the construction of shells. There is no single reason that accounts for the demise in the construction of shell structures, rather, it is a result of many factors. Then the construction seemed to stop and little was heard. For a decade, starting from 1956, the architectural magazines were full of examples of structures built by many different designers.
