What is the maximum spacing allowed between intermediate ties for a base greater than 3 feet?

The maximum spacing allowed between intermediate ties for a base greater than 3 feet is established to ensure the safety and stability of scaffolding structures. For scaffolding that has a base greater than 3 feet, the maximum spacing for intermediate ties is 26 feet. This regulation is grounded in safety standards, which dictate that the ties must adequately support the scaffold and prevent tipping or collapse. Spacing ties too far apart may compromise the scaffold's rigidity and structural integrity, increasing the risk of accidents or failure.

The determination of the distance is based on engineering principles that account for wind loads, material properties, and the overall configuration of the scaffold structure. Therefore, adhering to this maximum spacing is critical for maintaining safety standards and ensuring that the scaffold remains secure during use.
