It is good shoring practice, and strongly recommended by Hi-Lite that Lateral stability/strength be provided for by the falsework deck structure, with loads being taken to elements of the existing permanent structure.

A second alternative is to provide additional bracing by means of a tube and clamp system, taking lateral loads to the permanent structure; or to mudsills or other suitable resisting elements. Where these approaches are not practical, the Super Hi-Lite System may be used to resist lateral loads, with an accompanying derating of the vertical capacity.

The calculated capacities in Table 3are based on a 2.5 factor of safety on both the vertical and lateral loads combined to comply with the existing 1975 CSA Canadian Standards Association Code S269.1.
