Mapping
Detailed maps of underground infrastructure are regularly needed for infrastructure design. Subsurface utility mapping and engineering (SUM/SUE) service providers now turn to GPR for subsurface mapping to augment the traditional locating methods.  

By clearing an area with LMX100 GPR scanning, unknown or unrecorded buried structures can be identified and marked. Correlating responses with as-built records enables verification and identification of buried utilities. Vacuum excavation can then be targeted to expose GPR targets from undocumented infrastructure or natural obstructions. Total station or GPS surveying of mark-outs delivers updated georeferenced drawings for design needs.

  Design and planning new construction requires detailed understanding of the presence and location of potentially conflicting subsurface structures. This case study shows GPR used in the subsurface utility mapping and engineering (SUM/SUE) process for a new transit corridor.
