Note: Identified underground utilities have been interpreted from electronic detection utilising GPR and EMF. The utilities shown are an indication of their approximate location and depth (where shown). Furthermore, due to the quality of the GPR files collected on site this is the best possible identification of all items below ground we are able to achieve for a plan view drawing. There was a high level of impedance to the penetrating radar waves due to the blue metal on the surface. The EMF locating done on site assisted us in identifying the underground utilities, however interference from the energised switchyard does affect these readings. We have done our best to ensure the depths and locations correlate with the GPR data as close as possible under the circumstances.
