We locate the presence or absence of underground services on sites using ground penetrating radar (GPR) and electromagnetic equipment, such as CAT and genny.
Anybody wishing to dig, should by law (HSE regulations), know what services are located below, before breaking ground. Powers underground utility detection surveys will provide you with comprehensive services locations to the required PAS 128:2022 British Standard. They show the position, type and depth of live, abandoned or redundant service networks based on PAS 128:2022 Quality Levels (QL) agreed in advance.
Quality Assured PAS 128:2022 Surveys
PAS 128:2022 is a best practice specification in the gathering of underground services data, transformed into detailed drawings or models that show the location of services underground. Underground service locations can be identified to any of the PAS 128:2022 Quality Levels based on survey type, location accuracy, inclusion of post-processing and level of supporting data. We can work with you to determine which Quality Level can be achieved in advance of the site survey.
PAS 128 Quality Levels D, C, B, A:
Survey Level | Survey Type | Relative Location Accuracy | Relative Cost |
D | Desktop Utility Records Search | Lowest | Lowest |
C | Site Reconnaissance | Medium Low | Medium |
B | Detection | Medium High | Medium |
A | Verification | Highest | Highest |
“We are proud to say Erddig has been selected as one of the locations chosen by the Welsh Government and Natural Resources Wales to have a new commemorative woodland in remembrance of those lost during Covid-19. This project is extremely meaningful and having the Powers team on site conducting a topographic survey has helped us to determine the lay of the land and create a planting scheme for where the new trees will go. The Powers team was great at communicating with our team, and carried out the work quickly and effectively.”
