How we do it

40SEVEN’s most comprehensive service involves the 3-D mapping of all utilities on a site, including the identification, location and depth measurements of existing services.

Surveys can be presented as a detailed colour-coded, scale hard copy drawing or as a CAD file with digital photographs to aid understanding. They enable contractors to work with far greater confidence than if they used statutory records, which are often outdated, incomplete and inaccurate.

One of the increasingly popular solutions to gathering information about buried assets is Electronic Cross Sections (ECS), commonly known as trial scans.

40SEVEN typically scan and collect underground utility data from an area of two to three metres square. We have adopted the best available technology, techniques and procedures in order to generate an accurate and detailed map of utilities buried within the survey area.

Following completion of the survey you will be supplied with a photo of the survey area, a cross-section CAD drawing of services found. Additionally, we can supply you with an overhead plan if required.

Using trial scan techniques provide numerous benefits in comparison to traditional methods, for example, trial pits.

  • Little or nominal disruption to traffic or pedestrians as trial pits and traditional excavation techniques do not have to be used
  • No-dig technology
  • No additional scarring
  • No expensive re-instatement works
  • Environmentally friendly
  • High productivity
  • Low cost

Marking out of utilities should be performed prior to any excavation or drilling as a rule, rather than the exception.

Existing data on buried assets is often inaccurate, incomplete or out of date. Failure to establish the accurate position of a buried utility or other potential hazard is not only costly but has serious health and safety implications.

Our services can be applied to a wide range of projects and as well as being a comprehensive and convenient method of identifying the precise location of utilities, it is cost-effective and safer compared with traditional excavation methods.

Not all surveys requiring the location of buried services are the same. Your needs may differ from project to project and therefore we offer our experienced  Project Managers to discuss your needs, objectives of the survey and make recommendations to ensure the service that you buy is fit for purpose and meets expectations.
