A recent aerial survey by Overdrones on a church in North London has revealed missing stonework right at the top of the spire - where the lightning conductor meets the weather vane - previously invisible to even the most powerful binoculars.

The commissioning surveyor, Ryan Bunce & Co, praised the flexibility of the aerial drone survey by commenting: “No other form of survey could have revealed this potentially serious problem so quickly and so cost effectively”, he said. “We weren’t even looking for this fault - but the quality of drone and High Definition camera setup has enabled us to digitally zoom into this flaw to give us an accurate representation of the problem and how to remedy it before it caused major damage to the building”, he added.

Commenting on the project’s success Dean Overton, Director and Chief Pilot at Overdrones, said:” All drones are not the same. We operate in a completely different world to that of the ubiquitous, “hobbyist” type drone operators”. “Their low end drones”, he went on to say, “are just not up to the task of producing the quality necessary for a meaningful survey like this”. “What’s more”, he added, “by using two crew - as opposed to the single man operation of the “hobbyist” drones - we are able to maximise the quality of the output as well as improving the safety factor for the Client”.

Ryan Bunce & Co agreed with this analysis: “We are convinced that high quality aerial drone technology like this has an important role to play in the future of both building surveying and construction project marketing”.
