In New York City, more than 8,500 sidewalk sheds flank buildings and construction sites at any given time, obstructing nearly 2 million linear feet of sidewalk. While most remain in place for a year or more, these supposedly temporary structures have become permanent features of the urban streetscape. Intended to protect pedestrians from overhead construction debris, they undermine the aesthetic and social qualities of one of the most important and dynamic forms of public space—the sidewalk.
Typical sidewalk sheds are heavy, dark structures, which negatively affect businesses and neighborhood character. For something that occupies nearly half the area of Central Park shouldn’t some attention be paid to quality of design and public experience.
CORE CANOPY is a simple, transformative new sidewalk shed system that eliminates all horizontal and diagonal bracing, freeing sidewalks and storefronts from unnecessary physical and visual clutter. CORE CANOPY utilizes a patented moment-frame connection that allows both longitudinal and transverse beams to connect in-plane, creating an ultra-thin profile, while reducing impact on building facades.
Every sidewalk in NYC is different, so the design was developed to accommodate for variations in length, width, and height; have spans, step-ups, turn corners; respond to building and curb edge protrusions at both the sidewalk and deck level; and the application of multiple deck configurations depending on use: new construction, facade repair, etc.
Multiple prototypes were developed to refine CORE CANOPY’s design. A full-scale mock-up of the moment connection was built to test feasibility of fabrication and workability in the field. A full-scale single bay was constructed to test member sizes, weights, and assembly methods. Lastly, a multiple bay mock-up was built testing spans, step-ups, parapets, lighting and finishes.
CORE CANOPY is designed as a background object, one that prioritizes the pedestrian experience and minimizes it’s presence on the streetscape.
