The acquisition expands AECOM’s footprint in Europe. “INOCSA’s expertise in segments such as transportation—especially high-speed rail, which is a focus for us around the world—energy, environment and water make it a natural fit with AECOM’s worldwide suite of services,” said AECOM CEO John M. Dionisio.
