Abstract
In a machine for driving screw anchors and other foundation components, a desired embedment depth is calculated based on a minimum required embedment depth, work point height and length of available upper leg sections. Once calculated, the machine automatically drives the screw anchor to the depth so that one of the available upper leg lengths will fit between the driven screw anchor and apex truss hardware. If uplift is detected during driving, the machine will add additional embedment depth. In-situ validation of driven screw anchors may be performed after the embedment depth is reached.
