Green Infrastructure Design, Geotechnical and Geophysical Services, Brooklyn, NY; NYC Department of Environmental Protection/NYC Economic Development Corporation: Conducted soil borings at 250 bioswale locations. At each bioswale location, two borings were conducted, one (20-ft deep) for geotechnical data gathering (borings logs, SPT, soil sampling) and the other boring (10-ft deep) for conducting percolation/ infiltration tests at two depths. EG&R personnel performed logging, sampling, and percolation tests. Over 600 soil samples were collected, and laboratory tested for particle size. EG&R performed Ground Penetrating Radar (GPR) survey at all bioswale locations. Provided coordination with several State and City Agencies.

MMC Maintenance Yard, Power Improvements, New Jersey Transit, Kearney, NJ: 10 soil borings to a depth of 40 ft were conducted. Standard Penetration Tests (SPT) and soil sampling was performed continuously. Soil samples were collected for laboratory analysis (particle size analysis).

New Jersey School Construction Authority (Prime Consultant: Spector Group): Geotechnical investigations were conducted to obtain design data for the construction of a three-story building. A total of 28 soil borings were conducted to a depth of 40 ft. Rock coring was performed in 8 borings. Standard Penetration test (SPT) and continuous split-spoon sampling was conducted in each boring. Logging of the soil samples was performed using Unified Soil Classification System. Provided recommendations concerning foundation design, floor slab design, below grade walls, earthwork foundation, pavement design, and seismic design criteria.
