As the world continues to grow and urbanize, new urban infrastructure is being constructed at an unprecedented rate while old world infrastructure is being replaced and upgraded.  This has lead to a greater demand for accurate and current utility locating and mapping. This demand is further exacerbated by the fact that infrastructure construction costs continue to rise and the slightest delay or extra cost associated with insufficient utility locating has an even more profound affect on projects and communities.  Fortunately, the cost of advanced rapid 3D mapping has decreased considerably in the last few years, while the ease of use and speed with which data can be post-processed and made available has drastically improved.  This presentation covers advancements in rapid 3D mapping and how the creation of utility 3D digital twin can improve utility locating, support extraction of utilities from existing data, and support the creation of smart infrastructure and community-wide digital twins.
