When Westfield Corporation decided to build three parking structures to support a new, state of the art shopping mall near St. Louis, PBM/Raider Precast and CEG answered the call. Originally engineered as post-tensioned, cast-in-place (c.i.p.) concrete structures, these garages were re-engineered to utilize precast concrete systems. By converting from c.i.p. to precast, the owner saved money by shortening the construction schedule. By changing from eighteen-foot bays to thirty-six-foot bays, and by eliminating an expansion joint in one of the structures, even more was saved.

The superstructures of the three garages are made up entirely of precast components; including ornate cornice and cladding pieces, architectural spandrels, free-standing arches, a vehicular bridge, moment frames, and other structural members. Brick and stone material was applied in the field to enhance the appearance of the structures. The owner, Westfield (an Australian company), has built and continues to build shopping malls all over the country and the world. Their goal was to build their "showcase" shopping mall for the United States in Des Peres, Missouri, with considerable attention paid to detail, quality, and overall appearance. Since parking structures are the first and last impression mall customers receive, aesthetic detail and an "open look" were a high priority. These architectural requirements, along with significant engineering challenges were successfully met by PBM/Raider Concrete and CEG and resulted in three beautiful precast concrete parking structures.
