As seen through the green construction netting on-site, large hollow steel pilings are now sitting in the cold weather waiting to be driven into the ground by two piling machines at 9 DeKalb Avenue. Designed by SHoP Architects and developed by JDS Development and the Chetrit Group, excavation and foundation work for the 1,066-foot-tall supertall is making steady headway in Downtown Brooklyn.

Excavation is steadily making its way further down below street level while carefully unearthing the underside of the original existing walls for the Brooklyn Dime Savings Bank. A mixture of new diagonal steel bracings are being placed among the old steel structure in order to hold the northern flank, while excavation and construction progress behind and below. The bare concrete walls seen behind the pile driving machine in the photos above show where the landmarked and preserved lobby will meet with the ground floor of the new supertall.

When complete, dark-colored bronze and glass panels will enclose the reinforced concrete structure, and anchor the tower as the newest and tallest focal point in the Downtown Brooklyn skyline. The building could rise above street level sometime in the second half of 2019. This is the sixth-tallest project under construction in New York City and the tallest in Brooklyn.

Completion of 9 DeKalb Avenue is expected sometime in 2021.
