Zeichner Risk Analytics (ZRA) is located in the tallest building of the three Ballston Plaza office buildings in the northwest quadrant of North Glebe Road and North Fairfax Drive. It is located between the Marymount University Ballston Campus and I-66, and is recognizable by the CACI corporate sign at the top. Underground parking is available in our building. As unreserved parking can be limited, the entrance off Wakefield is the easiest place to arrange key transfer with the attendant (probably at the tandem spaces near the entrance). The maximum charge per day is currently $11.00. Hours of operation are from 7 a.m. to 11 p.m.
