Our topographical surveys are undertaken in 3D. This allows the results to be presented in contoured or terrain modelled formats.

The resultant survey models can then be utilised for requirements such as master planning, groundworks planning, planning applications etc.

Using measured survey data, volumes and quantities can be calculated utilising dedicated software.

Volumes are required in a range of instances, including: Stockpiles (Quarried aggregates, Soil mounds, Recycled aggregates, Coal stocks etc), Quarrying, Muckshifting, Cut & fill etc.

Whether it be for earthmoving planning purposes, costing/charging purposes, accurate volume information can be invaluable.

Water course surveying, where a series of cross sections are surveyed, to give a full picture of a specified length of watercourse is a specialist discipline. Our surveyors have surveyed and produced thousands of cross sections on a variety of rivers and other watercourses. Having river modelling knowledge and experience is invaluable during the data capture stage as when carried out correctly, it considerably improves the integrity of the final model results and ensures that all features of hydraulic significance are correctly recorded.

Once the site measurements have been completed, the gathered data is processed using specialised software to create the final model.

For carrying out this highly specialised survey work, CDM Surveys Limited employ the services of fully trained industry experienced surveyors, the latest electromagnetic, ground probing radar equipment, remote inspection equipment and proven techniques to detect and map underground services to a high degree of accuracy across a wide range of environments; including industrial, commercial, brown field and regeneration sites, urban and city centre locations.

We understand that knowing the accurate location, nature and depths of existing buried utilities is of paramount importance to those engaged in feasibility studies, design, construction and maintenance of assets.

Like Topographical Surveys and GPS Surveys, our Underground Utility Mapping services are often required by Architects, Building Developers and Engineers who need the specific details of underground features on a specific segment of land.

CCTV survey technology is the most cost effective and most efficient way to inspect sewers and drains. CCTV surveys are used when a drainage problem has been identified, or the client would like to inspect the drain to avoid any drainage problems in the future. The survey is a precise way to get an instant, accurate look at the current condition of underground drains.

To complete a CCTV drainage survey, we use a specialised remote-controlled camera system alongside a software that is specifically designed to survey for CCTV drains surveys. The images that the cameras relay allow our surveyors to assess the condition of the drains or sewer without disrupting the surrounding properties or environments.
