During the first 5 years after One Blackfriars was built, it wasn’t able to receive a successful all-around clean and therefore, it had only managed 2 out of 4 cleans a year.
This was due to the wind, the location and the shape of the building. Whilst architecture is becoming more unique in its designs – it can pose more challenges when it comes to window cleaning.
Blackfriars had 3 previously installed BMU’s for cradle cleaning, however, only one was used during previous cleans due to the winds – this created a longer window clean and meant deadlines weren’t met.
