The River Building for the Grace Farms Foundation blends into its surroundings, minimally impacting views across what was formerly farmland. The complex of glass- walled buildings – a sanctuary, a library, a dining hall, a pavilion, and a gymnasium – connected by a sloping, winding roof. The project is LEED Silver certified.
The final structural design comprises three primary elements: Hundreds of “flag pole” steel pipe columns, each individually fixed at their base, provide an overall lateral system that does not require crossing beams. A series of 10-inch by 10-inch steel beams curve in both axes and were fabricated through a digital transfer of data be- tween Silman and the fabricator. A single glulam type and size was modified throughout to address site-specific challenges. This included adding steel to create trusses over long spans and additional outrigger framing at longer overhangs. Local carpenters were able to build much of the roof structure, as the infill framing consisted primarily of standard sawn lumber or laminated wood beams for the longer spans.

Located on the banks of the Potomac River, the John F. Kennedy Center for the
Performing Arts is the nation’s busiest arts facility and home to the National
Symphony Orchestra, the Washington National Opera and the Suzanne Farrell Ballet.
The existing building was designed by Edward Durell Stone and opened in 1971.
The South Plaza Expansion project adds much-needed space for education,
rehearsal, and events. It consists of three partially-buried white concrete pavilions
cascading towards the river. The northern pavilion is the Entry Pavilion, the center is
the Glissando Pavilion, and the southern pavilion is the River Pavilion. A pedestrian
bridge spans Rock Creek Parkway, linking the new facilities to the waterfront.
Silman also designed the 2-story below grade structure that connects the pavilions
and sits under the occupiable landscape. The terrace level and pavilion roof slabs
consist of long span post-tensioned slab systems. A series of ruled vaults run
throughout the multi-level terrace that is framed in cast-in-place concrete. A parking
garage is also located below grade.
