ARCHES GIVE OPEN LOOK TO WASHINGTON METRO STATIONS

One of the early decisions in the planning for the Metro system was a design for the 53 underground passenger stations which is artistically pleasing as well as functional. The stations are semicircular in cross section, having very low sidewalls joined by a wide expanse of arch. Both sidewalls and arch feature a pattern of recessed coffers which become increasingly deep toward the center of the arch. The design eliminates the need for central pillars and roof supports, and provides the station with an open look which is unusual for underground construction. Blaw-Knox Equipment, which has supplied forms for 16 of the 19 stations built to date, approached the problem of forming by scaling up their tunnel-forming methods to match the size of the stations. Forming methods developed to overcome these problems have not only been economically successful, they have helped the construction crews stay on schedule.
