As building information modeling gains ground as a great tool for above-ground design and construction, new three-dimensional underground imaging technologies such as SUE PLUS -- Subsurface Utility Engineering that provides Precision Locating of Underground Structures -- has emerged to allow the AEC team to leverage the use of BIM for underground utilities and infrastructure. "[Subsurface utility engineering] is no less important than any other engineering discipline, and it has direct project cost impacts, it has social benefits, and it is of immense importance since it increases safety and reduces potential liability of project stakeholders," says Mark Wallbom.
