GSP 42.3-48 SUE


KMA provided subsurface utility engineering (SUE) services. The vacuum excavation method was used to verify the locations of major utilities and underground structures to determine potential impacts to the design of the planned mainline widening and bridge improvements.

A total of 52 test holes were excavated using a Vacmaster vacuum machine. Utilities identified and described in the survey along the GSP included telephone, fiber optic cable, and gas.
