Decking — Shored vs Unshored Decision
Shored vs Unshored Decision for composite floor and roof deck work.
Unshored construction is steel's default — the beam carries its own wet concrete. Shoring buys a flatter slab and a smaller beam at the price of renting a forest of props AND a re-shore schedule. The three-way trade (shore/camber/stiffen) is priced per project, never assumed.
Formula
Note: Erection-planning estimate only. Member weights, connection capacities and tolerances for execution must come from the issued drawings, the EOR and the erection engineer — never from a generic calculator.
