The consideration of the lateral stability of falsework is important.In the design of falsework, there is a difference between falsework which is top-restrained and falsework which is freestanding.Top-restrained falsework does not provide its own lateral stability but relies on external support. This support is normally provided by the adjacent permanent works.This TWf Information Sheet acts as a reminder to consider the lateral stability of falsework.TW23.067, 9.5.23
