Gas Holder drone Inspections- Bromley-By-Bow, Central London 

Updated: Jul 24, 2020

Last year we conducted a number of aerial UAS inspections to former Victorian gas holders around the Birmingham area for nationwide civil and structural engineering firm. So, when our client secured a further contract to carry out similar works in the London area, of course we were only too happy to conduct the flights for them again. 

The project involved 2 of 7 cast iron Victorian structures. The gas holders were built between 1872 and 1878 to a design by the engineers Clark & Kirkham. They are all grade II listed with Historic England.The site location sits nestled between the restricted London airspace of R160, R159 (Isle of Dogs), and London City Airport. The Runway Protection Zone (RPZ) of London City Airport was located approx. 1km away. All under the control of Heathrow Air Traffic Control (Class D airspace). 


Coupled with the airspace considerations, the site also sat adjacent to a nearby Transport For London rail lines and some potentially congested perimeter roads. 

Although a relatively complicated and congested area of aerial activity UAV, Global Drone Surveys were able to safely and legally conduct the work through our diligence and communication with required agencies, coupled with highly skilled and knowledgeable pilots and payload operators.
