Greenhorne & O’Mara signs letter of intent to join Stantec

Acquisitions of C3TS and Architecture 2000 also completed.


By Posted by Tim Gregorski, Senior Editor | December 4, 2012

North American design firm Stantec announced plans to acquire Mid-Atlantic-based engineering firm Greenhorne & O’Mara. The multidiscipline, 520-person firm will expand Stantec’s presence and services across the U.S. Atlantic coast, particularly in the transportation sector and with the US federal government. The transaction is expected to close by the end of the year, marking the third firm to join Stantec in the last quarter of 2012.

Headquartered in Laurel, Md., with 16 offices spread throughout the Mid-Atlantic and Southeast regions, Greenhorne & O’Mara specializes in the design of transportation facilities and other infrastructure, including highway and bridge design, traffic engineering, master planning and landscape architecture, structural engineering, U.S. Department of Defense services, and utilities design. Their work also includes particular expertise in water resource projects with U.S. federal agencies, such as flood hazard mitigation and floodplain mapping, National Environmental Policy Act (NEPA) compliance, wetlands delineation and permitting, environmental impact statements, and stormwater management.

Stantec also announced the completion of its acquisition of C3TS, a Florida engineering and design firm with 150 employees. The move established a much stronger presence for Stantec on Florida’s Atlantic coast, bringing total staff in the state to more than 350 in 12 offices. +
