![]() Side brackets, cantilevered platforms, pulleys or hoists and wind conditions must be considered and compensated with additional ties/or guides. ![]() The ties must be installed as the erection progresses and not removed until the scaffolding is dismantled to that height.Vertical ties must be placed at the end of the scaffolding and at no more than 30 feet horizontal intervals.The ties must be placed as close to the top as possible in case they are less than four times the minimum base width of the scaffolding. The bottom tie to the building must be placed no higher than four times the minimum base width and every 26 feet vertically thereafter.OSHA requires that scaffolding to be secured to the building when the height of the scaffolding exceeds four times the minimum base width.Wood planks used for scaffolding must be specifically approved and marked by an approved grading agency. Damaged or deteriorated equipment should not be used. Before erecting scaffolding all equipment must be inspected to make sure that they are in good condition and are serviceable. Stationary or fixed scaffolding over 125 feet in height and movable or rolling scaffolding over 60 feet in height must be designed by a professional engineer. ![]() The load carrying capacity information for scaffolding components is available from the manufacturer. ![]() Frame spacing and mudsill size can only be determined after calculating the total loads to be imposed on the scaffolding and the strength of the structure. Wind conditions and weather protection covering are also important considerations. The job site should be inspected for ground conditions, strength of the supporting building, proximity to power lines (minimum distance of 10 feet must be maintained between energized power lines and the scaffolding) and overhead obstructions. ![]()
