Mark Center Building

Mark Center Building is a government office complex in Alexandria that features two connected towers housing thousands of workers. The site sits on a large campus designed to bring multiple administrative departments together in one location.

In 2008 the government selected this site to bring several federal offices together in one secure location after a major reorganization. The construction responded to updated security requirements for administrative operations.

The Mark Center Building represents a shift in military facility planning, incorporating modern security requirements while maintaining administrative efficiency for thousands of personnel.

Access to the site requires passing through security checkpoints at multiple entrances on the campus. Visitors should expect restricted access and thorough security procedures for entry.

This structure stands as the tallest building constructed by the Army Corps of Engineers, accommodating approximately 6,500 Department of Defense employees.
