The new Central Library in San Diego was awarded the top prize by the American Society of Concrete Contractors' Decorative Concrete Council early this year. Among the notable features of the structure are a gravity arch; a 70-foot high reading-room roof and dome that has cast-in-place columns and 64-foot beams; and a cantilevered special-events roof. Morley Construction, project manager for the concrete installation, used 43,300 cubic yards of concrete to build what its crews call "our cathedral."
