BSI PAS128 surveying is a British Standard methodology for utility surveys in the UK.
Giving a more detailed result than standard surveys.
BOREHOLE CLEARANCE SURVEYS
Using ground-penetrating radar (GPR) and electromagnetic locators (EML), Rock Surveying can detect, trace and map buried utilities to confirm their exact location in the vicinity of proposed boreholes and excavations.
DESKTOP UTILITY SEARCHES
Desktop utility searches are carried out as part of due diligence when researching a project and are used to gain as much information as possible on the existing utilities under a proposed site.
SPECIALISTS IN HIGH-RISK ENVIRONMENTS
Rock Surveying offers underground utility surveying accurately locating the routing and depth of all buried services. We undertake surveys to PAS128 standard for borehole clearances, setting out locations, site mark-up at the construction stage and drainage connectivity, including CCTV.
Land and boundary surveys provide information on the legal ownership of a property and its land boundaries.
DRAINAGE MAPPING & CCTV
Drainage mapping provides accurate information of drains and sewers under a proposed site, including how building features will connect with drainage works.
