Architectural Precast Elements:
• Precast installation completed in five months
PROJECT OVERVIEW Symphony House Condominiums, a 507,000-square-foot, 32-story tower with ground-level retail, was constructed adjacent to a 25,000-square-foot theater and features a dramatic stepped-back silhouette. Terraces and overhanging balconies enhance the traditional feel.
The first eight levels contain parking, theater and retail and are clad in conventional precast panels. The upper 24 residential floors are clad in lightweight carbon-fiber reinforced precast concrete (GFRC) panels. The combination provided a variety of benefits.
PRECAST SOLUTION Backed with insulating EPS foam, the GFRC panels weigh only 30 pounds per square foot, less than half the weight of conventional precast concrete panels. The lighter weight made it easier to erect the panels high in the air in a busy neighborhood.
The design team had three non-negotiable requirements: aesthetics, color depth and consistency, and water-tightness. The precast concrete panels provided all three and also contributed to the building’s energy efficiency.
