By the time the Board of Estimate had approved City Center Tower, pouring of the concrete slabs was underway.[1] The project was being referred to as CitySpire by mid-1986, when European American Bank leased eight of the office stories.[80] The construction of CitySpire involved controversies over safety. Susan Guszynski of the Joffrey Ballet, a tenant in City Center, wrote a letter to the New York City Department of Buildings (DOB) in late 1986, alleging that three Joffrey staff had been hit by falling concrete during one week that October. The Buildings Department subsequently received four additional complaints of falling objects, including one instance in which a portion of the facade fell from the roof.[81] Neighbors also filed lawsuits claiming that CitySpire's construction had led to debris pileups and various incidents.[82][83] One neighbor claimed that he received death threats after complaining to the police about cracked windows, while another neighbor was allegedly raped after an attacker climbed into her apartment through CitySpire's scaffolding.[82]
