Improved collaboration with BIM/CIM models – Wisconsin DOT

The construction of the busiest interchange in the state of Wisconsin is on its way.  The work involves an active use of  digital BIM / CIM models which replace inefficient paper-based communication and enable combination of final construction geometry with key information such as dimensions, volumes, coordinates, construction materials and quality requirements. The engineered 3D model  allows the entire project team to see roadway design updates, and smart functionality such as automated clash detection helps both designers and engineers to spot potential clashes.

Construction of a busy interchange area

———————————————————-

The Zoo Interchange is Wisconsin’s busiest interchange connecting 12 miles of I-94, I-894 and US 45 corridors and also reconstruction of 5 miles of adjacent streets in western Milwaukee County, Wisconsin near the Milwaukee County Zoo. Construction is underway with costs estimated to be 1.7B$ during 2012 – 2018. The work involves 68 bridges including 6 RR structures, 1 system / 7 service interchanges, 108 retaining walls, 15 noise walls, 2 box culverts, 115 sign structures & numerous utilities. CIM-VDC 3D modeling is one of the key components in the Zoo IC design process.

Wisconsin DOT started by piloting the Viasys VDC solution in 2012. Today, all of the design data has been integrated into a single collaboration model that is actively used for design analysis, e.g. for clash detection, 4D and 5D simulations. A smooth integration to Autodesk® Civil 3D® allows engineers to see roadway design updates and search clashes immediately inside the combined CIM model.

Viasys VDC product family provides Wisconsin DOT with the needed cost-effective solution for advanced modeling. The ability to support open data model standard formats like LandXML and IFC is critical in a major project like Zoo IC allowing data import from other key design systems such as Bentley® InRoads® and Autodesk® Revit®. The parametric modeling approach enabled by VDC Modeler software helps convert design disciplines still working in 2D to 3D. Furthermore, the software readily attaches materials and textures for automatic and rapid model visualization.
