Joint venture to design and oversee project to clean tributaries around New York City.

LOS ANGELES (July 7, 2010) — AECOM Technology Corporation (NYSE: ACM), a leading provider of professional technical and management support services for government and commercial clients around the world, announced today 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 US$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.

“We are pleased to have the opportunity to further strengthen our relationship with the NYCDEP through efforts, such as this one, that have a positive environmental impact on the city,” said John M. Dionisio, AECOM president and chief executive officer. 

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.
