Project Summary Founded in 1924, Barton Malow delivers a broad range of construction services, including general contracting and construction management. From planning to closeout, Barton Malow can help advance even the largest and most complex projects more efficiently. Two steel production lines currently under construction for the steelmaker Severstal North America Dearborn (Severstal Dearborn) illustrate Barton Malow's proactive approach to project delivery. To help manage the projects, Barton Malow uses Building Information Modeling (BIM) software from Autodesk, including Autodesk ® Navisworks ® Manage, Autodesk ® Revit ® Structure, Autodesk ® Revit ® Architecture, and Autodesk ® Revit ® MEP software. Playing a key role from preconstruction to handover to the client, BIM is an integrated process that has helped Barton Malow to: • Visualize, explore, and understand project characteristics before construction • Resolve interferences in advance and prevent additional construction costs • Save time by completing some tasks as much as 88 percent faster • Provide a model-based handover deliverable to the owner that will help minimize startup time and ongoing operational costs The Challenge The Severstal Dearborn construction projects consist of a new pickling line and tandem cold mill in an existing steel manufacturing facility. In addition, a new hot dip coating line provides automakers with high-quality automotive steel. When complete, the combined construction cost of the production lines will exceed US$200 million. Construction on the lines began in 2008, with Barton Malow building only the hot dip coating line. The projects were approximately 20 percent complete when, facing economic challenges common to the steel industry, the client put them on hold. When construction was restarted in 2010, Severstal Dearborn chose Barton Malow to manage all construction for both lines and to self-perform all civil work, equipment setting, and boilermaker work. According to Joe Benvenuto, project manager with Barton Malow, "Restarting the projects led to many challenges. We saw the BIM process as a means to help identify or eliminate potential problems before they became cost or schedule risk items." The Solution Before deploying crews to restart construction on the lines, Barton Malow revisited the preconstruction aspects of the projects using a BIM-based process. For the concrete portions, Barton Malow created a detailed structural model in Autodesk Revit Structure software. Within the model, Barton Malow identified the prebuilt portions A handover as solid as steel. Barton Malow uses BIM for preconstruction, construction, and handover of steel production lines at the Severstal Dearborn Plant.
