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.
