For months we watched the big steel and glass structure rise at Liberty and Fifth avenues, and we've often wondered, "What's the view from the building's balcony?" Well, here it is. Three PNC Plaza is the first skyscraper to be built in Pittsburgh since 1987. This view is from the 12th floor outdoor terrace of Reed Smith's law offices. The firm moved to its new location Aug. 10. Looking out over the city is George Stewart, Reed Smith's managing partner.
