The project marked the first use of 3D modeling software by WisDOT. The department obtained laser mapping units, new desktop, laptop, and tablet computers, and GPS rovers in preparation of the project. Two terabytes of data were generated from surveying the site. Computer-generated models of the new interchange design could then be created. The models were uploaded to GPS rovers at the site which used them to search for any conflicts with utilities. Data collected by the rovers was then entered into the modeling software so conflicts could be resolved. Finished models were shared with contractors so they would not have to make their own. Model data was also used for automated machine guidance during construction.
