WATERFRONT PARK AND PLAYGROUND
MARKET BUILDING
BOROUGH OF BROOKLYN, NEW YORK

The proposed project included an settlement analysis and remediation for the construction of a waterfront park and playground for the Market Building located at Greenpoint, Brooklyn, New York.  The property is bordered by India Street to the south, Huron Street on the north, and residential buildings to the east.

JZN Engineering evaluated the settlement of the proposed waterfront park/playground area by the construction of a finite element model to analyze the surcharge behavior of the fill materials on to the underlying soft compressible organic deposits.  Following the analysis, JZN prepared a subgrade preparation consisting of the overexcavation and disposal of the environmentally impacted soils, and restoring the area using geofabric and lightweight fill material.

JZN recommendation included design parameters for the subgrade preparation for the waterfront park/playground areas. In addition, JZN provided construction quality control during the remediation and construction process of the park/playground area.
