Naturally, there are concerns after, per the Sun, a "65 square-foot panel of steel and glass" fell from the Bank of America building at 6th Avenue and 42nd Street in Midtown yesterday. Two people were injured; a construction worker at the Verizon building across the street described seeing the panel to the Daily News, "We looked up and saw this piece of glass covering the entire sky." A stop-work order for exterior work was placed at the site and safety violations were issued to Tishman Construction. Though this is the 6th time since 2006 in which material has fallen from the building, a Tishman spokesman said, "We do not see a pattern with regard to previous incidents...It's undetermined as to what happened was mechanical or human. Something did not happen normally this time."
