TECHNICAL OVERVIEW

We understand that knowing the identification, accurate location, and depths of existing buried utilities is of paramount importance to those engaged in feasibility projects, design, construction and maintenance of buried assets. As an experienced specialist we remove the uncertainty associated with reliance on old, incomplete, unclear or unavailable record information. We use the latest dual frequency ground penetrating radar systems along with Radiodetection's latest RD8100 Precision Locators to conduct your utility mapping survey.

Our Process

We will receive an initial enquiry about a project.

Survey boundaries are discussed and defined. Along with site address, contacts and access arrangements/constraints.

Prior to our site visits we request for the Topographical base plan to be provided to us along with any Utility Record Drawings that may be available, if there are none available we offer to do a Desktop Utility Record Search pack.

Once this has all been arranged and is in place we go to site to conduct our on site Utility Mapping Survey.

We recommend that the survey area is cleared ahead of, and for the duration of the survey, as vehicles, construction materials, temporary fencing or other obstructions may limit the effectiveness of our investigation.

If practicable, areas of vegetation should be cleared ahead of our arrival.

If practicable, areas of grass should be topped/mown as short as possible ahead of our arrival. Instruction should be given to estate management or grass mowing teams not to operate whilst surveying is underway, unless agreed with the survey team, as survey ground markings may be lost; necessitating works to be re-done.

If possible, site occupiers should be made aware of our survey and requirements ahead of our arrival.

The client should make us aware of any known unusual or site specific hazards as soon as is reasonably practicable, and ahead of our arrival on site. 

See example of our Method statement.

Once all survey data has been collected on site, the results are taken back into the office where the data can be processed and the CAD drawings produced, after vigorous checks these drawings are then released to the client.

DRAWINGS PROVIDED

We issue both PDF and latest AutoCAD drawings of our survey results.

All of our drawings would be issued onto the Topographical base plan provided to us in AutoCAD format, each colour coded line is individually layered with clear depths and notes referencing to the line, which can be found in the drawing legend.
