Climbing down a 25 story building inspecting the windows one after another is not a simple job. Despite years of innovation, some jobs are still done manually. With the help better quality support, safety kits and materials people involve themselves in some of the tough and dangerous jobs dealing with extreme height, pressure or both. If you are working on the window sills of such a high building wind speeds can be a big hurdle for operating safely. These require the best people trained in such trade and experts in their work.
To ensure not just safety of the personnel but also the satisfactory completion of the project such highly qualified tradesperson is required. To enable a seamless and error-free work, some of these might be performed more than once. For example, window reglazing is a process that consumes a lot of time. It cannot be done fast or easily. It needs proper attention to detail while your operator is hanging some 150 meters above the ground. Such conditions can be really fatiguing. To allow work of only high standards industries dealing with technical access and specialized access have people to do work like rope access inspections. These only deal with the primary work of surveying the property manually using nothing but ropeways. In this case, not that fun-filled ride though. So, what are your choices? Next to none. With aerial survey technology using things like drones, we are still far away from anything like a machine that can do the filling of cracks using sealants or reglazing the windows. That is still very much a job for humans.
So, removing those fancy aerial drones and quadropters from the equation, you still need a company that has the best-trained people in this sport, those who have years of experience, and tools to take up big projects spanning days and weeks. For example, abseiling window cleaners are very common workers but it requires a lot of bravery to go ahead. People who are extremely brilliant in using ropes, handling equipment high above in the air and being calm can only go ahead. This requires medical fitness and skills that can be tested even when you are drunk. Such is the level of training imparted on the staff. These windows are hard to access and therefore cleaning is done seldom. Yet, only companies’ experts in the same can access the otherwise extremely difficult regions outside the building, on its walls and exterior, because tough jobs are best left to experts in those fields.
