 The New York Daily News alleged that the subway project was very unsafe . For example , on August 8 , 2012 , an explosion caused rocks to fly all over an intersection . Less than two weeks later , on August 21 , 2012 , an uncontrolled blast for the station was done incorrectly , causing a large explosion that sent debris into the air and broke windows of buildings in the area and damaged nearby sidewalks . In another instance , contaminated rocks were carried away from a construction site on 63rd Street , and the incident went unnoticed . On March 19 , 2013 , in yet another allegation of wrongdoing , a construction worker got stuck in waist @-@ deep muck at the 96th Street station site , but while he was extricated after four hours of rescue efforts , he nearly died after the incident .
