The remaking of the 6.5 million-sf Pentagon building is complete—17 years after it began. The renovation of the world’s largest office building was completed ahead of schedule and below cost. The project, a complete interior transformation, is considered such a success that its design-build techniques have influenced other federal projects.

The Arlington, Va. structure was gutted and rebuilt from slab to ceiling in five phases, one for each section of the building. “We took the building apart and put it together again, with 20,000 people sitting in it,” said Lee Evey, who oversaw the effort for five years.
Improvements and upgrades include:

• Installation of about 177 miles of cable tray to carry wiring.
• Installation of 70 passenger elevators.
• Construction of an airy two-story dining atrium of terrazzo, stainless steel, and glass.
• Complete upgrade of electric and communications utilities.

The Pentagon had not met National Electrical Code standards since 1953, and it averaged 20 to 30 power failures a day before the project.
