Because soil conditions vary considerably from site to site, Strong Poles cannot design any portion of the pole foundation, or even recommend a minimum standard. When ordered, we supply anchor bolt assemblies that are sized based on the stress involved at the pole base. We recommend that our customers should consult with a local structural engineer who is familiar with the sites’ soil conditions. They will reference other building codes that use more in depth definitions of soil conditions and loads. Strong Poles will be happy to provide base reaction information for the SteadyMax poles (overturning moment and shear), if the Engineer needs the additional data for the design.
