Decking — Concrete on Deck Volume
Concrete on Deck Volume for composite floor and roof deck work.
Concrete on unshored deck always over-runs the geometric volume: beams deflect under the wet load and the dish refills to level — the ponding allowance is real concrete that real pumps must supply. Eight percent surprises only the people who didn't add it.
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.

About Decking — Concrete on Deck Volume
Decking — Concrete on Deck Volume computes the governing relationship V = A × (topping + flute equiv) × (1 + ponding) live as you type. Concrete on unshored deck always over-runs the geometric volume: beams deflect under the wet load and the dish refills to level — the ponding allowance is real concrete that real pumps must supply. Eight percent surprises only the people who didn't add it. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Decking — Concrete on Deck Volume
- 1Enter your values — Deck area, Topping above flutes, Average flute fill, Ponding from deflection (sensible defaults are pre-filled).
- 2Read the live results: Concrete volume.
- 3Check the "with your numbers" line to see V = A × (topping + flute equiv) × (1 + ponding) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Decking — Concrete on Deck Volume?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula V = A × (topping + flute equiv) × (1 + ponding) with authoritative sources cited on the page (SDI — Steel Deck Institute manuals; AISC 303 — Code of Standard Practice for Steel Buildings)
- ✓Concrete on unshored deck always over-runs the geometric volume: beams deflect under the wet load and the dish refills to level — the ponding allowance is real concrete that real pumps must supply.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the decking — concrete on deck volume use?+
It evaluates V = A × (topping + flute equiv) × (1 + ponding), exactly as published. Sources: SDI — Steel Deck Institute manuals; AISC 303 — Code of Standard Practice for Steel Buildings. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Concrete on unshored deck always over-runs the geometric volume: beams deflect under the wet load and the dish refills to level — the ponding allowance is real concrete that real pumps must supply. 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.
When is this calculator the right tool for the job?+
Concrete on Deck Volume for composite floor and roof deck work. A free structural steel delivery & erection tool. Eight percent surprises only the people who didn't add it. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
