Abstract:For over a decade, the Minnesota Department of Transportation (MnDOT) has pursued Digital As-Builts (DABs) both strategically and pragmatically. MnDOT uses DABs to maintain current information about specific asset classes as they are renewed or created through the construction process. However, manual, field-based processes are resource intensive. MnDOT is now considering how new design technology can introduce efficiencies into the DABs process. MnDOT has two pilot projects that have developed and piloted a more streamlined, model-based methodology. This case study describes how MnDOT is maturing the DABs program by considering the Transportation Asset Management System (TAMS) data needs while implementing digital project delivery. The case study further describes the model-based workflows developed on one pilot project that will be used to deliver DABs on a second pilot project. Finally, this case study describes how MnDOT has continuously evolved the DABs program alongside new developments in TAMS data collection to make use of the most efficient data collection method for each asset class.
