Revit BIM Experience Award Winner
Walter P Moore is an engineering and consulting firm that specializes in structural and infrastructure engineering. Founded in 1931, Walter P Moore is headquartered in Texas and has more than 400 professionals in 12 offices coast to coast. The firm has built a reputation for mastering engineering challenges (like the Houston Astrodome, the world’s first domed stadium) and undertakes a large variety of building types--from convention centers and performance halls to airports, sports stadiums, corporate campuses, entertainment centers, healthcare and education facilities, and urban roadway systems and other infrastructure.
An early adopter of Revit Structure, Walter P Moore has used the software in production since the fall of 2005 with 90 projects executed using Revit Structure, including 45 projects completed through to construction documentation. The firm’s structural engineering practice has completely transitioned to the Revit Structure platform and frequently collaborates with architects using Revit Architecture. The firm also uses Autodesk NavisWorks for inter-discipline design collaboration and coordination with their architecture and MEP project partners. Recognizing the potential of integrated 3D delivery platforms, the firm has embraced AutoCAD Civil 3D and anticipates 100% adoption within its civil engineering group by the end of 2008.

Notable Revit BIM Projects
University of Florida, Biomedical Sciences Building
Project: Currently in design development, this multi-disciplinary biomedical research facility at the University of Florida will serve as a center for animal research into genetics and cancer. The 160,000-square foot facility will house a state-of-the-art animal care facility and provide nearly 85,000 square feet of laboratory and research space. In addition, it will also provide facility office space and administrative space for the biomedical sciences department. The concrete-framed structure is six levels, the top floor being a mechanical penthouse. The building interfaces with adjacent structures on two sides, and each floor is approximately 17,000 square feet.
BIM Experience: The use of the Autodesk BIM approach on this project has resulted in a significant time savings on the project schedule to date. The reduction in time is due to a series of efficiencies throughout the design process, such as the ability of Revit to automatically coordinate the construction documentation and the design model, the use of a single model for both design and structural analysis, and the use of Autodesk NavisWorks for inter-discipline clash detection and design coordination.
To facilitate that design coordination, this project also features close collaboration with the architect (who uses Revit Architecture) and the project’s MEP engineering firm (who uses AutoCAD MEP). The shared Autodesk structural, architectural and mechanical models are integrated through the use of Autodesk NavisWorks, enabling the cross-discipline design coordination and clash detection. The team has been able to coordinate components across the major design disciplines even to the point of overlaying the architect’s reflective ceiling plan grids and the diffuser locations from the mechanical system to verify alignment—resulting in a dramatic reduction of interferences.
U.S. Federal Courthouse, Jackson, Mississippi
Project: This new $92.4 million facility is currently in construction and will provide six district courtrooms, three magistrate courtrooms, three bankruptcy courtrooms, and 14 chambers (district, magistrate, bankruptcy and court of appeals). As a U.S. federal government building, the project must conform to the rules set forth by the U.S. General Services Administration (GSA)—the government agency which builds and manages federal facilities. The eight-level structure—a combination of concrete and structural steel—was designed in accordance with GSA security guidelines to prevent progressive collapse and in accordance with the GSA’s blast design criteria.
BIM Experience: Walter P Moore employed Revit Structure on this landmark project for the GSA’s BIM pilot program, collaborating with H3 Hardy Collaboration Architecture using Revit Architecture, and Cook, Douglass, Farr, Lemons using AutoCAD MEP.
Project reviews were conducted using a combined building model instead of the traditional two-dimensional drawings. This enabled all the project stakeholders—the GSA, the design teams, even the contractors and trades—to see the design as it evolved and get a better understanding of the project. Autodesk NavisWorks was used to bring the models together for inter-discipline coordination and clash detection.
The improvements derived from use of BIM were particularly noticeable on this project because it was started using traditional drawing-based design methods—before Walter P Moore had transitioned to Revit. At the start of the design development stage, the structural design team began using Revit Structure and discovered numerous coordination errors that had been overlooked using standard drawings.
As a part of the BIM pilot program, material schedules were extracted from the model for use in comparing against the material quantities developed by the contractor using a traditional approach of estimating quantities from the drawings alone. Results of this comparative exercise showed that the BIM-based material schedules compared favorably with those produced by the traditional, and more costly, approach. Significant value was achieved by leveraging the individual discipline models in a higher order collaboration process.
