The structure, which was under construction, failed around 2pm. The roof on the top level of the stair tower collapsed, causing a chain reaction, according to Philadelphia Mayor Cherelle Parker. 'A precast roof segment failed and fell to the level below, literally triggering a progressive collapse of connected sections across all seven levels,' Parker said following the partial collapse.
