"In the immediate wake of the terrorist attacks on the World Trade Center on September 11, 2001, managers and owners of high-rise office structures across the country scrambled to design and implement improved security measures—from turning lobbies into security checkpoints to surrounding buildings with concrete barriers originally designed for use as highway medians. (See “Customizing Security,” page 42, June 2002 Urban Land.) Now that a year has passed, however, many tenants are becoming less tolerant of the disruption and unsightliness of these safeguards. "Since 9/11, the perception has changed. Originally, tenants needed to see the added security, but as of late, they are starting to swing back to wanting value for their dollar. In addition, they are beginning to complain about delays," reports Joe Geist, director of property management for Thomas Properties Group in Philadelphia."
