The top of the Silvertooth Judicial Center in downtown Sarasota was incredibly dirty and needed to be cleaned, but the County had a limited budget to do so. We proposed to clean from the 2’ wide parapet catwalk at the top of the building which meant that our hoses had to be run up almost 180’ from the ground based trucks (pictured) and we had to clean walls that towered above us without ladders. We invented cleaning devices with a propulsion jet to stay again the walls and to clean. We lowered them over the side to clean down as far as we could reach. All work was in a very high security area and had to be monitored by guards at all times. (Sorry, some of the before and after shots are out of sequence, but I am sure you can figure that out).
