Most importantly, the construction model can continue to deliver advantages to the company long after construction is complete. Bill McNab, project manager with Severstal Dearborn explains, "The BIM model and Autodesk Navisworks will give us a way to visualize components and equipment in detail as we maintain the production lines. There's no question that BIM has helped us to save money on construction costs, and we expect it will help with training operators and maintenance personnel in our facility in the future." The Result As the steel production lines advance toward completion, Barton Malow and Severstal Dearborn see the benefits of BIM touching virtually every aspect of the projects, from preconstruction to handover. Benvenuto notes, "BIM improves and accelerates even the most routine tasks. For instance, we're able to prepare layouts for concrete pours 88 percent faster. From the big stuff to day- to-day construction, BIM software from Autodesk helps keep complex projects on track." Learn More Enhance your construction process with BIM.

"People think of BIM primarily as a design tool," says Benvenuto. "But BIM gives us the power to explore how we want to build in advance, as well as streamlining our field processes. On the Severstal Dearborn project, Autodesk Revit Structure helped us set up layout controls, design-build 5,000 yards of concrete duct bank, and clarify some incredibly complicated foundations. The construction team saved time and reduced the risk of rework." Eliminating Clashes The use of BIM on the projects extended well beyond the concrete work Barton Malow self- performs. The Barton Malow team and their sub- contractors modeled the 6,000 drawings that made up the rest of the construction documentation. Each contractor utilized its own software, with not all of the contractors utilizing Autodesk products. Autodesk Navisworks software allowed Barton Malow to aggregate the various model files into a single, integrated project model. Referring to the model as a guide, Barton Malow explored and visualized its construction plans in collaboration with the engineers and subcontractors. "With the Navisworks model, everyone can more easily visualize the project as a whole," explains Chris Horney, project engineer for Barton Malow. "That catalyzes collaboration across the project team. Navisworks helps us share ideas about how to optimize construction sequencing, and makes it easier to capture those ideas." The Autodesk Navisworks model also proved invaluable for helping resolve coordination issues across disciplines. Within Navisworks software, the team performed clash detection tests. A significant number of conflicts were identified. By working with the project engineers, the team resolved clashes. "Due to the complexity of the production lines, there were a number of clashes between elements such as equipment, encased conduit, piping, existing concrete, and structural steel," explains Horney. "The ability to bring together multiple file types within Autodesk Navisworks software was a huge advantage on this job." BIM for Commissioning and Handover Using Autodesk ® BIM 360™ Field, a cloud-based service, Barton Malow is leveraging BIM in the field for construction, commissioning, and ultimately, handover. BIM 360 Field allows workers on the job site to update construction information on mobile devices. Automated integration between the BIM 360 Field service and Autodesk Navisworks software helps keep the single project model updated. Critical information is then available in Navisworks as a BIM-based handover deliverable to the owner. This creates value in ongoing operations as owners can save time by finding key documents for training staff and important data, such as warranty start dates for equipment. According to Horney, using BIM in the field should prove especially valuable during equipment commissioning, "Synchronizing the commissioning process with BIM 360 Field and Navisworks can allow us to link accurate install dates, maintenance manuals, and operational information to the project model. We're saving time as we capture critical data on materials, systems, and equipment." BIM for Operations Throughout the project, Severstal Dearborn has reviewed the construction model with extended project stakeholders using Autodesk ® Navisworks ® Freedom software, a free* visualization tool. It has helped them keep up with progress and provide feedback. BIM accelerates construction planning processes by as much as 88 percent. *Free products are subject to the terms and conditions of the end-user license agreement that accompanies download of the software.
