Investigators will require months to determine the causes of two accidents that killed three union ironworkers on Feb. 8.
The family of the Chicago ironworker, Kenneth Puplava, 43, has filed suit in Cook County Circuit Court, alleging contractor negligence in the collapse of a steel structure that struck him at a suburban hospital construction site. The suit names the project’s general contractor, Pepper Construction Co., Chicago, and its steel erector-fabricator, Lejeune Steel Co., Minneapolis, which employed Puplava.
