Starting in April of 2012, Draper Aden Associates began marking all of the existing utilities associated with Miss Utility marking tickets (roughly 10-20/week). DAA monitors the on-call system, marks underground utilities as needed, and codes the ticket for the positive response. We also document our marking by collecting our designations using sub-foot handheld GPS which UVA utilizes to check and update their GIS. Through the use of surface geophysical tools, including electromagnetic radio frequency, ground penetrating radar, and RFID marker balls combined with sub-foot handheld GPS, we are able to provide University of Virginia with valuable information to numerous departments across UVA including Facilities Management; Energy & Utilities; Facilities Planning & Construction; the Office of the Architect; and Space & Real Estate Management for planning, operational, and budgeting purposes. With the subsurface utility information collected, through both traditional and innovative new technologies, we are able to provide the University with accurate information that is compatible with their existing GIS Map.
