Built in 1924 on Chicago’s picturesque lakefront, the old Soldier Field had grown antiquated. The 1,441,000-square-foot Soldier Field was scheduled for completion in a record 20 months, even though a typical stadium requires 30 months or more.
Infrastructure work started in July 2001, six months before the Bears’ last game of the season. Early phased work included the rerouting of sewers, water, power and construction of two major electric vaults. By the time the Bears played their final game on Jan. 20, 2002, power was rerouted through new underground utilities networked throughout the 92-acre site, and construction of the new stadium launched at 12:01 a.m. Jan 21.
