A system for fabricating a slab from a construction material having both unhardened and hardened states includes a form panel unit and a pair of spaced structural supporting members. The supporting members are adapted for assisting in supporting said slab made the construction material. The form panel unit includes a panel member adapted for use as part of a form to retain said construction material when in an unhardened state and has generally opposed upper and lower surfaces. The panel unit also has at least one reinforcement unit having at least one reinforcement member mounted above the upper surface of the panel member is interconnected to the panel member. The form panel unit is configured so that the panel member can be positioned between the supporting members, such that said unhardened construction material can be retained above the upper surface of the panel member to permit hardening of said construction material from its unhardened state to its hardened state. The reinforcement member has a portion mounted on at least one of the supporting members so that the panel member is at least in part suspended from at least one supporting member, and wherein the supporting member has an upper portion extending above the upper surface of said panel member so as to be embedded in the construction material.
