U.S. headquarters

The 55,000–square–foot building consolidated Canadian National′s Midwest and Gulf Division offices. Work included completion of core– and–shell and interior construction in a seven–month timeframe. The project marks a new chapter in Graycor′s work with the railroad. In 1926, Graycor removed a section of retaining wall along the railroad tracks belonging to CN′s predecessor, Illinois Central Railroad, on the east side of Michigan Avenue in Chicago. Completed in a driving snowstorm without interrupting train traffic, the project helped establish Graycor′s reputation for rising to a challenge and inspired the company′s slogan — Wanted: a hard job.
