We are qualified UAV pilots with CAA Permission for Commercial Operations for both Rotary
and Fixed wing UAV projects. Being both building surveyors and UAV operators allows us to
not only fly the missions to capture the data, we can provide interpretation and recommendations
based on the data also. We use leading photogrammetry software to enable us to convert done captured
data into detailed 3D building models and maps.
Core Services:
+ Difficult Access inspection and report
We are able to provide HD photos and video of difficult to reach locations without the requirement
to hire in expensive access equipment or risk personnel working at height. Our drones stream a live
HD feed to a ground station, allowing clients to view areas of interest in real time.
+ Façade Mapping
Using our UAV mounted HD camera and photogrammetry process we are able to produce accurate, detailed
geometrically corrected orthomosiac’s of building facades. This service allows clients to obtain a
detailed survey of a building façade, with the option to digitise areas of interest.
+ Aerial mapping
Using UAV’s to capture data allows large areas to be mapped efficiently and quickly. Accurate,
georeferenced orthomosaics, digital terrain models, point clouds and contour maps are provided,
always checked against traditionally surveyed ground control points to ensure accuracy.
+ Stockpile Analysis
We can provide rapid and accurate stockpile analysis, allowing for clients to determine cut and fill
volumes quickly and safely. The use of drones removes the requirement for personnel to enter areas where
machines may be working, allowing operations to continue in quarries for example without the need for
interruption for surveying works.
+ 3D Building modelling
We are able to provide accurate, detailed point cloud data derived from photogrammetry of building roofs,
facades and the site. The 3D point cloud data is then drawn into a 3D model of the building, either in 3D
AutoCad or Revit as required by the client.
+ 4K Video and Photos
Our drones are equipped with 4K cameras, if you just want photos and video of your site we can provide that
too.

large area topographical surface model. Client required a grid digital surface model at
200mm centres.

+ Roof survey support
+ Project to support a land surveying practice with the
production of a full 3D drawing of a roof complex. The client was using laser scanning
for the elevations and internals, however no safe access was available to the roof. We
were tasked to provide a high res point cloud of the roof to tie into the existing laser
scanning data.
