Description:
30-32 Bushwick Avenue is a new eight-story building with a partial cellar in Bushwick, Brooklyn, New York, designed to be a multi-family residential building. The new building is framed with CMU shear walls and exterior walls with concrete slab on decks on steel infill framing. Each floor included one front and two rear cantilevering walkable balconies for the tenants to use. This building was within the limits of an adjacent MTA subway line, so additional care was used for the substructure to adhere to MTA requirements and regulations.
Stratford was in charge of designing the superstructure, as well as the building’s foundations and support of excavation. The foundation included a concrete mat foundation with several grade beams and strip footings to provide lateral stability and supports for vertical elements. In addition, benched footings were used throughout the foundation to avoid underpinning the existing adjacent structures.
The support of excavation system involved grouted-steel micropiles with wood lagging at the street-facing front of the building to stabilize the soil adjacent to the existing MTA tunnel. Micropiles and lagging were also used at the South of the building, in order to stabilize the adjacent building’s backyard. Steel rakers tying back to two heel blocks were also used throughout the SOE system.
