Summary

PROJECT OVERVIEW

The project consisted of installing a support of excavation system comprised of 129 drilled-in soldier piles and over 1,000 linear feet of steel sheet piling. The site, which was over eight acres in size, was the largest open spill for petroleum contamination the NYSDEC had in the state at that time. The total proposed development size was over 1,000,000 sq ft of mixed used space.

WHAT MADE THIS JOB COMPLEX

The large amount of grossly contaminated soil in close proximity to the East River and the adjoining properties made the installation of the support system as well as the excavation of over 100,000 tons of soil extremely difficult. Working in a densely populated area, as well as near a major body of water, we needed to safeguard the surrounding public and environment from offsite exposures.

HOW POSILLICO SOLVED IT

As excavation and drilling took place adjacent to the neighboring buildings and street, we constructed a custom vapor and debris containment system that consisted of a curtain and air scrubber. The curtain was raised and lowered as needed and a portable air intake was used to capture the vapors and neutralize them prior to being released into the atmosphere. This system ensured safety and minimized risk of contaminants from reaching the public.
