There are questions that are relevant around spalling where the concrete falls off of the structural elements, Mr. Schlesinger said. /Width 48 However, if you use the definition of failure to be any building system or component that does not perform as expected then building failures are much more commonplace not to mention costly to repair. Issue: Temperature variance, untested integrity. Video captured from south of the building appears to show it collapsing in stages.
