Manhattan East Side Access
Waste Management and Environmental Consulting
The $7.2 billion East Side Access project was designed to connect the Long Island Rail Road’s (LIRR) Main and Port Washington lines in Queens to a new LIRR terminal beneath Grand Central Terminal in Manhattan. The new connection will increase the LIRR’s capacity into Manhattan by 45% while dramatically shortening the average travel time for Long Island and eastern Queens commuters by 27 minutes.
Impact Environmental’s Waste Management Team was chosen to be the Environmental Coordinator of record for the Queen’s Launch Tunnel Project. This is one of New York City’s largest projects undertaken in the last decade. Impact Environmental secured the contract because the project perfectly blended the firm’s two principal areas of business: consulting and contracting. Specifically, this involves our consulting expertise in groundwater dewatering issues combined with the contracting of off-site soil management. The $30 million project called for the removal of 1 million tons of soil.
We first researched and reviewed all historical land use information that dated back to the late 1800’s. This covered miles of land along the project site. We performed a visual inspection to determine any potential sources of contamination, then compared our visual findings to the historical records.
We then compiled hundreds of laboratory samples and reports and managed the data through EDEN, our Environmental Data Evaluation Network process. EDEN analyzed the data, classified the waste, and distilled the project down to simple procedures for managing the entire waste site. After determining the levels of constituents using criteria based on regulatory limits, EDEN identified the options for its removal and reuse. At the end of the day, EDEN took thousands of pages of confusion and came up with two pages of efficient procedures that could then be followed by the construction engineers.
We are transported the soil and rock off site and the material is currently being beneficially reused as engineering control media at approved Brownfield and mine reclamation sites.
Impact Environmental successfully completed waste-support related services for the CQ31 portion of the four Queens tunnel structures in 2013 – within the allotted 18-month period. We safely removed over 10,000 linear feet of tunnel soil and rock. Impact is currently providing environmental and engineering services for the CH053, CH054, CQ032 contracts for the project. With more contracts starting in the future where we will provide more waste management and environmental turn-key services. Every phase of the project will be fully documented to ensure liability reduction and accountability. And all of our work is covered by a $25 million insurance policy.
“Impact Environmental’s turn-key management expertise in deep tunnel excavation hydrogeology and regulatory disciplines was pivotal in completing this project.”
