GLA has relocated to its new 75,000-sq.ft. headquarters in O'Fallon, Missouri. GLA provides telecommunications consulting services, and also has offices in Houston and Dallas, Texas; Portland, Maine and Visalia, California.  The exterior of the building features architectural pre-cast panels rendered in blended shades of gray and red aggregate.  Curtainwalls of reflective glass brighten its west and south faces.  Surface and underground parking will accommodate 406 vehicles.

Finishes include a classroom-style training facility and two modern cafe-style break areas - each featuring a balcony overlooking woodlands.
