Underground Utilities Tracing

The detection and mapping of utility surveys can be one of the most beneficial surveys done before a building project.
The failure to identify the locations of buried services before a project takes place can result in increased costs and delays, as well as serious health and safety implications. Services drawing obtained from utility companies are not always sufficiently accurate to allow for proper planning.

What is a Utility Survey?

It is a series of non-intrusive measurements undertaken before site works commencing. They can locate the positions of buried services and help reduce costly delays and risks. They can be used across all locations and projects from industrial, commercial, and new builds to rural areas and city centre sites.

What is it used for?

Utility surveys are used to locate underground pipelines and wires to locate water, power, gas, telecommunications, fibre optics, and drainage so that these services are not disturbed during any building or excavation works. We can cross-reference our findings with local utility drawing records.


What are the benefits of an Utility Survey?

The biggest benefit is the cost and time saved on a project. Minor errors in the location of utilities can cause lengthy delays that can be difficult to rectify and make companies liable for any damage that is caused due to their project.

What can you expect from our Utility Survey?

EMP Surveys uses radio detection and ground penetrating radar techniques to locate underground utilities. The services can be mapped accurately, and results supplied in CAD format.

Verification (PAS 128 type A)

This type of survey can complement a detection survey (survey type B). By visual inspection, we can obtain further information to improve the confidence level and obtain additional information about a particular service. Visual inspection of a service can be via access points such as manhole / inspection chamber, or by its excavation and exposure. For further details about confined space entry or utility excavation, please contact us to discuss further.

Detection (PAS 128 type B)

This survey is accompanied by a desktop utility report (survey type D). The detection survey is a non-penetrative survey conducted using at least 2 geophysical survey techniques. A consultation with the client during the quotation phase will identify the methodology used to conduct the survey. The final deliverable will be in the form of an AutoCAD file with a quality/confidence level assigned to all located services, and accompanied by a written report and photographic record.

Site reconnaissance (PAS 128 type C)

This survey is accompanied by a desktop utility report (survey type D). It will involve a site reconnaissance visit to identify features that may indicate the presence of a service such as; manholes, valves, utility markers, street furniture and historic excavation scars. The deliverable will be in the form of a records overlay onto an existing topographical survey or OS base plan.

Desktop utility records search (PAS 128 type D)

This survey type would be in the form of a report identifying all known utility owners and their assets within an area including a list of affected and non-affected providers, along with any plans, maps, and diagrams provided. The deliverable would be in the form of a PDF document containing all information.
