WSP USA Gains Position as a Leader in Environmental Services

The world’s sixth-largest environmental consulting business now delivers full capabilities in the U.S. following completion of strategic acquisitions.

NEW YORK — WSP USA, an engineering and professional services company, has completed the integration and rebranding of Ecology and Environment Inc. (E&E) and LT Environmental (LTE), marking the company’s emergence as a full-service provider and leader in the U.S environment market.

The addition of recently acquired E&E and LTE delivers approximately $75 million in new revenue and a strong backlog of work into 2021. WSP USA’s expanded capabilities now include ecosystem and site restoration, and renewable energy feasibility, as well as enhanced expertise in the company’s best-in-class sustainability and climate change services.

“Under the WSP brand, the additions of E&E and LTE — and the previously rebranded Louis Berger — create one of the largest and most technically diverse environmental forces in the U.S.,” said Steven Paquette, president of WSP’s Water and Environment business in the U.S. “The infusion of expertise both enhances and supplements our core competencies, and allows us to provide more cohesive, encompassing solutions to the increasingly complex and interconnected challenges confronting our clients.”

Prior to the acquisitions, WSP ranked as the sixth-largest (by revenue) environmental consulting business in the world, according to Engineering News-Record’s Top 200 Environmental Firms for 2020. The acquisitions increase the U.S. Environment practice threefold, to roughly 1,200 professionals, across the U.S.

The company aims to deepen its work in multiple markets, such as state and federal agencies, oil and gas, industrial manufacturing and real estate development. Additionally, E&E and LTE’s digital advancements strengthen WSP USA’s offering of proprietary technology, such as in stakeholder engagement, georeferencing and mapping tools, remote solar-powered remediation and continuous emissions monitoring systems for oil and gas facilities.

The integration already has produced successful outcomes for clients and communities, including the restoration of Shirley Chisholm State Park in New York City from landfill to active waterfront community asset. Combined teams also started work on the OceanBased Hydrokinetic Energy Project, a first of its kind program to provide commercial scale renewable energy from the Gulf Stream. And combined teams have won project awards from the U.S. Army Corps of Engineers, Buffalo District Great Lakes Restoration Initiative and Florida Department of Environmental Protection.

“As we come together under the WSP brand, our teams already understand how to collaborate efficiently and leverage the talents of each member,” Paquette said. “They are in step and delivering elevated value to clients right out of the gate.”
