Abstract
A system for forming concrete structural elements including a plurality of runners forming a spaced array; a plurality of supports extending upwardly from and connecting intersecting runners; and a plurality of coffer plates secured in position over the supports by a plurality of anchor nuts capable of interacting with the concrete poured to form the structural element. The coffer plates initially act as a mold for the structural element being formed. Thereafter, the array of runners and supports are used to suspend finishing components (plumbing lines, eletrical conduit, electrical wiring and fixtures, ceilings, non-load-bearing walls, etc.) from the structural element without requiring alteration of the concrete forming the structural element.
