LOS ANGELES — AECOM Technology Corporation, a provider of professional, technical, and management support services for government and commercial clients around the world, announced that a joint venture in which it participates with HydroQual, Inc., has been selected to provide dredge design, engineering, and permitting services to the New York City Department of Environmental Protection (NYCDEP) for the Citywide Dredging Engineering Design Contract Services project.
Under the $21-million contract, the joint venture will design and oversee the dredging of various tributaries around the city to remove combined sewer overflow (CSO) mounds that contribute to nuisance odors and dissolved oxygen deficits at the head end of the tributaries. These dredging programs are required by the city’s Consent Order Mandated Citywide CSO Long-Term Control Plans.
The project includes detailed sediment characterization; water quality sampling and lab analysis; dredge volume estimation; cap design; water-quality modeling; coordination and submission of all necessary permits with local, state, and federal agencies; coordination with ongoing U.S. Army Corps of Engineer restoration projects; environmental assessment/impact statements; and public outreach for each targeted dredging area. These services will be required on an expedited schedule to enable the NYCDEP to effectively comply with the city’s mandates.
