As well as carrying out a full Utility Mapping Survey, we do provide CAT scans whereby the position, type and depth of buried services & utilities are sprayed onto the ground surface.
We can either survey a whole area or provide service clearance for a number of invasive Ground Investigation (GI) locations or positions. This includes borehole, window sample, trial pit or core sample locations.
Example Utility Mark Out Survey
Although a drawing is not provided, the methodology used is the same (use of EML, cover lifting and GPR) as for any other utility mapping survey with GPR targets sprayed onto the ground surface in real time.
This provides a cost effective alternative when smaller excavations are planned, such as the installation of bollards, signs and flag poles, or to mark up services prior to cable route installations.
