The fire department's public education unit visited the45-story, 1.4-million-sf bank headquarters Oct. 21 to conduct adrill, fire commissioner Cortez Trotter reported. "This is one ofthe buildings we've been able to reach out to and conduct thesedrills," he said during a press conference Tuesday.

In addition, the building's management team from Jones LangLaSalle and engineering staff also cooperated by sharing floorplans with firefighters as well as developing a disaster plan."They had a working knowledge of the building, they had a workingknowledge of the plans and a working knowledge of the firedepartment's expectations," Trotter said.

Thebuilding also was being retrofitted for a sprinkler system,something that is likely to be required by the city council laterthis month. "Some of the things they had in place were not evenrequired," Trotter said of 135 S. LaSalle St.
