As Poseidon's son, the Greek god Orion could walk on water. That's about the only thing Orion Group Holdings (formerly Orion Marine) doesn't do when it comes to water. Through operating subsidiaries, the company provides civil construction and maintenance services for marine infrastructure, including pipelines, bridges, waterways, and port and other transportation facilities. It also performs dredging, surveying, inspections, excavation, and demolition services. Orion Marine serves government, commercial, and industrial clients; government projects account for some three-fourths of its revenues. The company operates in the Gulf Coast, Atlantic Seaboard, West Coast, Pacific Northwest, and Caribbean Basin regions.
