It continues to be used in this way.
The building site covers approximately 1.7 acres. The building has eight floors and a basement. It stands approximately 108 feet tall and has three passenger elevators, plus one freight elevator. It provides 156,942 rentable square feet of space for more than 200 federal employees.
