Value Delivered

Shambaugh did the plant layout of the facility process and utility systems utilizing 3-D computer modeling, allowing the customer to walk through the facility and make changes before piping fabrication began, thus eliminating costly changes to work already installed. Shambaugh finished this key project on time and on budget.

Client Objectives

Steel Dynamics needed to add production capacity at its Columbia City, Indiana, mill—including a water treatment facility—that would allow the plant to produce a higher volume of rail products and add lighter-weight structural shapes and merchant bars to its product offerings.

When in full operation, the mill expansion needed to add capacity of 600,000 tons per year and bring Columbia City’s finished steel production capacity to 1.6 million tons per year.

Scope of Services

Shambaugh’s commercial mechanical and plumbing services scope of work included the layout, prefabrication, and installation of piping and equipment for the process water, plumbing, and chemical systems in the new treatment facility.

Mechanical Process Piping Services Highlights:

  • 3-D modeling of building and piping layout
  • Piping sizes from ¼” tubing to 36” carbon steel pipe
  • Piping material included stainless steel, PVC, CPVC, and carbon steel
  • Prefabrication of over 70% of process piping
  • Installation of piping to over 40 pumps, six sand filters, storage tanks, and instrumentation and controls.
  • Piping systems included contact and non-contact cooling water, compressed air, natural gas, sour air, domestic water, sanitary waste and vent, sludge, and oxygen
