Four winners were named in the Concrete Reinforcing Steel Institute's 1994 Design Award competition. Held every two years, the awards - which are co-sponsored and monitored by the American Institute of Architects - honor structures built of cast-in-place reinforced concrete. Judging criteria included architectural aesthetics, engineering achievement, functional excellence, efficient use of materials, and a structure's relationship to its environment. The projects selected as winners in this year's competitions are: Quad District parking structure, University of California at Davis; NationsBank Corporate Center, Charlotte, N.C.; Georgia World Congress Center expansion, Atlanta; and University of California Science Library, Santa Cruz. CRSI is a non-profit organization dedicated to furthering the quality, design, and construction of cast-in-place reinforced concrete.
