We have completed a large amount of Topographical and UAV surveys for GA Smiths, predominantly these surveys are used for volumetric analysis of sites and quarries they are working on. Some of the better know sites would be places such as Glensanda and Duntilland quarries where new areas of the quarries are being opened up, we provided the relevant surveys before, during and after to record progress continually and calculate the overall quantities removed from these areas.
