Towards AR-enabled informed decision-making in subsurface utility projects through visualising 3D capture data of as-built utilities

This paper examines how AR-enabled informed decision-making can be facilitated through visualising 3D capture data of as-built subsurface utilities. Through semi-structured interviews with respondents from the underground construction industry, it was reviled that visualising 3D capture data in AR help prevent excavation damages and otherwise aid the decision-making processes involved in planning and excavating subsurface infrastructure through, 1) allowing evaluation of positional placement of subsurface infrastructure, 2) Showing underground utilities, not accessible through traditional utility records and 3) improving the visualisation of utility types and materials.
