co joined assembly 10 fortification of structural integrity may include strengthening structural integrity to enable a modular fill material forming co joined assembly to better withstand stresses that may be induced by lifting and transporting especially if loaded with rebar accordingly at least one strengthening element may be established on a modular fill material forming co joined assembly 10 a strengthening element may be an element that imparts adequate or perhaps merely increased strength to the structural integrity of a modular fill material forming co joined assembly 10 under some circumstances a strengthening element may be a high strength fastener joining a lift securement element 20 to a component of a modular fill material forming co joined assembly 10 of course a modular fill material forming co joined assembly 10 may have a centroid 45 under some circumstances it may be that a centroid 45 of a modular fill material forming co joined assembly 10 may be estimated prior to positioning a lift securement element 20 in some applications a centroid 45 of a modular fill material forming co joined assembly 10 may be a mass centroid 45 or an area centroid 45 a centroid 45 of a modular fill material forming co joined assembly 10 may further have an axis of lift an axis of lift for a centroid 45 of a modular fill material forming co joined assembly 10 may be an axis oriented in the direction in which a modular fill material forming co joined assembly 10 may be lifted in some situations an axis of lift for a centroid 45 of a modular fill material forming co joined.
