OCCI boasts a deep history collaborating with the U.S. Corps of Engineers and other clients on vital Lock and Dam infrastructure rehabilitation. Leveraging our expertise in marine conditions and extensive knowledge of large hydraulic structures and their components, OCCI is uniquely qualified to execute a wide range of challenging marine construction projects.
We excel at successfully completing rehab projects on some of the nation's most critical infrastructure, consistently working within tight outage schedules that demand precise execution to ensure water transportation remains uninhibited. OCCI specializes in performing work that involves complex access challenges on or over the water.
Our team consists of highly skilled workers specializing in critical, in-situ procedures. This includes field welding according to stringent standards like AWS D1.5 for fracture-critical steel components, ensuring the structural integrity of large gates and mechanisms. We perform field machining to meet extremely tight tolerances on components like trunnion pins and bearing surfaces. Additionally, we conduct mass concrete pours for various applications, such as structural repairs to lock walls, monoliths, and pier additions, all while working within dynamic marine conditions.
