The scaffold baseplates and mudsills increase the area where the downward forces of the scaffold are transmitted. However, complex or unusual scaffolds should be purpose-designed, with loading calculations and design drawings signed off by a chartered engineer or scaffold designer, with the scaffold company building to that design. Damage an obligation to make good any damage within a reasonable time period. While an engineering degree is not a prerequisite, that assessment normally requires some technical skills, and the competent person making that determination would have to have those skills.
