Selected by a jury of three architects, the five winning entries in the 1994 Concrete Building Awards sponsored by the Portland Cement Association (PCA) illustrate the use of concrete as a sculptural, structural, and unifying design element. The winning architects chose concrete for such attributes as aesthetics, cost effectiveness, energy efficiency, and environmental considerations. The winning projects range in size from a two-story hillside residence to a 12-acre, $220 million wastewater treatment plant.
