TFT’s Unmanned Aerial Vehicle (UAV) carried out condition surveys on otherwise inaccessible roofs as part of a Planned Preventative Maintenance programme for the Royal Borough of Windsor and Maidenhead.

We were instructed to undertake a schedule of condition and planned preventative maintenance programme on Windsor’s Guildhall and Theatre Royal. Both buildings are listed and both required a good understanding of their current condition in order for the client to obtain the required funding to maintain these landmark structures.

The roofs provide limited access from within and due to their location adjacent to Windsor Castle, closing the road for a platform lift was not possible in the timescale as the Changing of the Guard parade passed by on a regular basis. The solution was to use an Unmanned Aerial Vehicle (UAV) to traverse the entire roof area and stream High Definition video imagery of every detail. The quality of the footage has opened up previously inaccessible areas, allowing us to comment on the condition and highlight any areas of concern to the client. This information will provide the Council with relevant information to enable them to obtain the necessary funding, ensuring that these landmark buildings are properly maintained, that future work is planned for and that these buildings continue to serve the public.
