Underground Utility Location
Whether you are designing or constructing the need to know where existing buried services is critical to ensure that both safety and costs are controlled. At 40SEVEN we offer a range of utility location and mapping services to suit your needs and your project. The risk-reduction that non-intrusive utility location methods offer can give you peace of mind as well as show best practice.By using a combination of latest technologies and good surveying practises we can accurately locate and map buried pipes and cables of all types. With regulation increasing in the UK and recent prosecution under the NSWA legislation it is now even more important that you take the appropriate action to deal with services before, during and after excavation.
GPR Surveys
The use of Ground Penetrating Radar (GPR) has become standard in the majority of utility location and mapping surveys where there could be a presence of non-metallic services present. As much of the UK"s ageing services infrastructure is undergoing replacement with new non-conductive pipes it is imperative that surveying techniques keep up with the demands as the location of these pipes is often more difficult. GPR can prove to be an effective tool for this type of locate thus reducing your risk of striking a PE Gas pipe that can not be found using conventional CAT and Genny type equipment!GPR is also an effective approach for locating other underground points of interest such as structures and voids. Using the same principle as when looking for utilities, we are mapping the differences in the properties of the ground and the interpretation the radargram returned. When working in support of core sampling it may also able to show the the varying strata across a site.

We pride ourselves on being able to deliver a high quality product and meeting clients delivery requirements without compromise.Topographical Surveys provide a detailed picture of an area of land. All features are shown to a level of detail and scale appropriate to the individual project. Surveys can be related to National (OS) Grid and Datum, generally by the use of GPS. Each surveyed point is positioned in 3 dimensions, allowing drawings to be shown with contours and spot levels, which then allow us to produce accurate ground models and 3D visualisations if required.
CCTV Surveys
