Pentagon Renovation Program

The Pentagon Renovation Program or PENREN was a long-term project by the United States Department of Defense to perform a complete slab-to-slab renovation of The Pentagon in Arlington, Virginia. The program began in the 1990s, and was completed in June 2011. The full-scale renovation became necessary because by the mid-1990s, the Pentagon had never undergone a major renovation, and building systems had deteriorated beyond repair, requiring complete replacement. Asbestos throughout the building made almost any building work complex and disruptive. The Defense Authorization Act of 1991 transferred control of the Pentagon Reservation from the General Services Administration to the Department of Defense, and established the Pentagon Reservation Maintenance Revolving Fund, designed to fund Pentagon renovations. This move enabled the Secretary of Defense to determine rent rates for Pentagon tenants to help fund the renovation.
