66 SEPTEMBER 2018 COATINGSPROMAG.COM in that the crew was working high in the air on roofs sloping at 7:12, 9:12, and 14:12, 35 days is a very short time frame. Steep Slopes = Safety Concerns With extreme slopes such as those found on the Colonnade Office Tower roofs, ensuring proper fall protection is a huge challenge. According to Moore, approximately 100,000 square feet (9,290.3 m²) of the project was a 7:12 slope, 35,000 square feet (3,251.6 m²) was a 9:12 slope, and 25,000 square feet (2,322.6 m²) was a 14:12 slope. "Power washing a flat roof and installing a slippery silicone coating is treacherous enough. Working at these slopes and at elevations between 75 and 100 feet [22.9–30.5 m] was extremely difficult," said Moore. Permanent anchor points were engineered and installed around the base of the roofs at 10 feet (3.1 m) on-center. ese anchor points were used as part of the fall protection system; however, they were only a part of the intricate safety solutions used by the West Roofing team. Granite Industries Coping Type Guardrail Systems were installed at 8 feet (2.4 m) on-center. "ese deploy a vice style anchor to the top of the parapet, extending 42 inches [106.7 cm] above the parapet wall and providing a secondary protection system," stated Moore. To begin the safety line installation in each section of the roofs, it was necessary to get a rope started over the top of the metal roof system from the gutter access point. According to Moore, the height to ridge was over 30 feet (9.1 m) vertically and 54 feet (16.5 m) horizontally, creating a difficult start to the process. "We utilized a powder-actuated rope gun to shoot the starter rope over the ridge, then tied on the larger life line rope, and dragged that up and over the ridge to the anchor point, providing a fall arrest anchor point rated to 5,000 pounds [2,268.0 kg] at the base on the opposite side. is provided a first point to be able to climb to the ridge of the roof where we then installed additional positioning anchor points, at 10 feet [3.1 m] on-center, where the applicators would tie a second life line to keep them positioned while they were installing the products or washing the roofs," explained Moore. e powder-actuated rope gun may sound like a gadget used in James Bond and other spy films, but in reality, it is a device origi- nally developed for the rock climbing world. It is now also a useful tool for many roofers. West Roofing used one from Landfall. e crews were also outfitted with 3M's DBI Sala and Miller Tower harnesses designed for rappelling skyscrapers. ese harnesses afforded the crew relative comfort while ascending and descending the extreme slopes. "Our guys were literally outfitted with rock climbing gear, including helmets and soft-sole mountain climbing boots. Our rope grabs and ascend- ers were designed for use in rock climbing and had all the safety ratings required for use in this application," explained Moore. At certain times during the job, the crew also wore magne- tized boots designed for use in accessing metal roof systems. e magnetized boots by Cougar Paws provided more traction when the roof was wet and slippery. And when the crew was applying the silicone coating system, they wore disposable Tyvek pants and shirts, as well as 3M half-masks with cartridge respirators. e extreme slope of the roof even made the final manufac- turer's warranty inspection challenging. "Most inspectors are not used to walking 14:12 slopes.
