ORN

Orion Group Holdings Inc

A specialty construction company that builds and repairs marine infrastructure—bridges, ports, waterways, and underwater pipelines—alongside concrete work for warehouses, parking garages, and industrial sites. Founded in 1994 as Orion Marine Group, it took its current name in 2016 after folding in a commercial concrete business, and traces a lineage spanning decades through earlier acquisitions. The name echoes the stars sailors once used for navigation, a fitting fit for a firm that works on, above, and below the water.
