Increasing knowledge whilst creating dramatic efficiencies

The Avon gorge is one of the most familiar landmarks in Bristol, a geological marvel that has played an important role in shaping the local inhabitants since the Iron Age.

As some of the cliff faces boarder a road, detailed surveys of the gorge need to be carried out at regular intervals. Ordinarily such geological surveys involve teams of climbers working in difficult and dangerous conditions over a significant period of time and frequently leads to road closures with resulting traffic disruption and cost to the city council who are required to ensure that the cliff face poses no threat to the road below. In an ever increasing effort to modernise, save cost and create efficiencies the city council commissioned a detailed survey of a two- kilometre stretch of the cliff face on the Clifton side of the gorge using the latest drone and sensor technology.

Future Aerial were selected to capture the large amounts of high definition imagery and data whilst working closely with engineering consultants to create a detailed analysis of the rock faces. The imagery has been used to create a 3D map of the gorge that can be revisited and referenced to analyse areas of interest or concern. The project is believed to be the first of its kind anywhere in the country.
