Precast and prestressed concrete, together with architectura l precast concrete, were used innovatively to build the new $13 million, fivestory 333 West Eleventh Street office building in Kansas City, Missouri. Adjacent and beneath the building are two below-grade and three abovegrade levels for parking vehicles. The precast/ prestressed structural system provided an economical way for the designers to match the 60 ft (18.3 m) parking bays below to the overhead office spaces. The exterior of the building featurescurves, overhangs and roof details that are created imaginatively from a combination of wide glass expanses, curta in wall and thin-brick-set architectural precast panels. This article presents the design and construction challenges, architectural and structural features, design considerations as well as the production and erection highlights of the project.
