Expansion project features four complex swoop designs, starting as flat green roofs and then rotating into vertical green walls.
The REACH is the Kennedy Center’s first expansion since its opening in 1971. This historic, $250 million expansion project aims to make the Center a 21st-century cultural campus and arts incubator. The expansion of classrooms, stages, and rehearsal space is located mostly underground, with approximately 69,000 square feet of green roof above it.
American Hydrotech provided a green roof with insulation and waterproofing for the entire project. The REACH features four complex swoop designs, which start as flat green roofs and rotate into vertical walls. Due to the complexity of the three-dimensional swoops, a test mock-up was devised several months beforehand by James Myers Roofing, American Hydrotech, and Sempergreen called “The Ramp.” It was checked on monthly to work out any potential problems before installation.
Hydrotech’s GardNet growing media confinement component provides soil stabilization for the swoops. Three of the swoops employed Sempergreen’s sedum mats, and the fourth swoop along the Potomac River is planted with perennial grasses. In addition, Hydrotech provided its LiteTop soil as part of the media substrate mix for the swoops.
The REACH is an impressive combination of architecture and landscape design, and it’s gotten the attention it deserves! A 16-day Opening Festival was held in September 2019, featuring more than 1,000 artists and 500 free events. The REACH is in the process of achieving LEED Gold certification.
