What McGraw Kokosing, Inc. does

McGraw Kokosing, Inc. is an industrial maintenance contractor specializing in multi-craft services and pipe fabrication, operating as a wholly-owned subsidiary of Kokosing — a third-generation, family-owned construction company founded in 1951 and headquartered in Westerville, Ohio. McGraw Kokosing serves industrial customers across the Midwest and Mid-Atlantic, providing industrial construction, rigging, equipment erection, pipe fabrication, electrical, instrumentation, structural steel, boiler work, and concrete excavation. Its client base spans steel mills, power generation facilities, electric transmission operators, and manufacturing plants, with services structured to address plant downtime reduction, emergency repairs, scheduled outages, and capital improvements.

The company's technical backbone is anchored by the McGraw Kokosing Off-Site Manufacturing (MK OSM) facility in Monroe, Ohio — a 232,000 sq-ft site with a 50,000 sq-ft fabrication area featuring CNC pipe profiling, multiple welding capabilities, six cranes up to 20-ton capacity, and ASME and National Board S, U, and R certifications. BIM-to-Fabrication workflows allow direct translation of engineer designs into exact cuts and welding specifications, supporting prefabricated pipe spools, structural weldments, multi-component skids and racks, and pre-commissioning testing. Hydrostatic testing capabilities cover steel and HDPE pipelines for natural gas and waterline systems, with compliance under DOT/PHMSA, Gold Shovel, ISNetworld, and Veriforce frameworks.

McGraw Kokosing is part of a broader construction portfolio that includes Kokosing Construction Company (transportation/sitework), Kokosing Industrial (heavy civil, industrial manufacturing, marine, power & energy, water treatment), Integrity Kokosing Pipeline Services, Kokosing Materials (asphalt), The Olen Corporation (aggregates), and Kokosing Solar. Revenue is generated through project-based competitive bidding for government clients (state DOTs, municipalities, federal agencies such as the U.S. Army Corps of Engineers) and direct negotiation with private industrial clients, with project values ranging from $100,000 to over $3 billion. Joint ventures with Walsh Construction, Alberici Constructors, Traylor Brothers, and McLean Contracting enable the group to pursue mega-projects beyond any single entity's balance sheet, and alternative delivery models (PPP, CMAR/CMGC, design-build) are increasingly part of the go-to-market motion.
