Who we work with
What can aerial drone surveys be used for?
A variety of sites can be mapped with a drone, and they are particularly effective for large land and topographic surveys.
They also offer a great solution for capturing data on inaccessible areas to facilitate roof inspections, removing the need for costly and time intensive scaffolding or cherry pickers and MEWP’s.
Drones can also be used for construction inspections acting as a quick and efficient solution for monitoring progress and providing as-built data on a construction project.
Environmental & Property conditions
Drone surveys can also be used to capture photogrammetry for environmental and property condition surveys resulting in high-resolution orthomosaics. The viewer can use these detailed images to visualise small previously unreachable areas.
Thermal detection surveys
We are also finding drone surveys are useful for thermal detection and thermal imaging for BREEAM compliance, where a thermal imaging camera can be used to detect differences in heat emitting from a building or site both during the day and at night.
What are the benefits of an aerial drone survey?
Drone surveys offer a versatile solution for mapping large sites. A topographic survey that previously would require two surveyors on site for a week can be completed in just hours. This increase in productivity and efficiency of our surveyors, saves time and reduces the cost of the survey while maintaining the quality and accuracy of the data.
As mentioned above the drone mapping survey makes inaccessible locations accessible for data capture and surveys can be conducted with minimal disruption to the site or property being mapped. They also minimise health and safety risk on site through use of remote LiDAR measurements.
Are there any restrictions when using a drone for a survey?
Our Aerial Drone Survey partners are licenced by the CAA (Civil Aviation Authority) and are subject to the UK aviation regulations. This ensures that all legalities are covered when commissioning CADS for an aerial drone survey.
Drone surveys are also not suitable for capturing data on densely wooded land and cannot be undertaken during adverse weather conditions.
In collaboration with you, we will define a specification which meets your requirements and ensures the most appropriate technology is employed. Please get in touch with us if you have a project that you would like to discuss.

Topographic drone survey and traditional measured building survey at a Scottish school
Our client, a renowned UK architectural practice, commissioned CADS to deliver a topographic and measured building survey. The data was required for an extension and refurbishment project of a Scottish primary school.
Given the extent of the site, over 75,000 sqm, we recommended using a drone to capture the topographic element of the survey. The drone mounted with a LiDAR scanner and data sensors captured the basic building footprint, eaves and ridge heights of the category B listed building. This was detailed to LoD1 in the topographic digital terrain model.
In addition CADS undertook a 2D measured building survey using a terrestrial laser scanner; and the deliverables included 2D floor plans, sections and external elevations.
