Drone audit first

PwC UK has undertaken a stock count audit using a drone for the first time. It is all part of the Big 4 firm’s wider drive to harness emerging technologies to enhance audit quality and efficiency.

The drone, which was manufactured and operated by QuestUAV captured over 300 images of the coal reserves at one the UK’s last remaining coal-fired power stations, Aberthaw in South Wales.

The images from the drone were used to create a point cloud ‘digital twin’ of the coal pile in order to measure its volume. The value of the coal was then calculated to within 99+% accuracy based on that volume measurement.
