Only the product (not its connection to the site) is pre-engineered. Each installation requires a site-specific foundation to be designed by a locally licensed Structural Engineer.
We provide Loading Criteria and Sample Foundation Designs based upon typical Arizona soil and weather conditions. It is essential that a Structural Engineer, licensed local to the installation, design the foundation according to the installation's soil and weather conditions.
The Sample Foundation Designs are NOT FOR CONSTRUCTION. It is necessary, however, to use the anchor bolt sizes and layouts shown therein.
