Column Formwork (Shuttering) Area Calculator
Shuttering contact area for rectangular RCC columns — the m² number quantity surveyors bill.
Formwork is measured on CONTACT area only — column tops and footing seats don't count. Beams: 2 sides + soffit; slabs: soffit only. CPWD norms allow 10–12 reuses of ply shuttering.
Formula
Column Formwork (Shuttering) Area Calculator is a free formwork area calculator for civil engineers, contractors and quantity surveyors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Column Formwork (Shuttering) Area Calculator
Shuttering contact area for rectangular RCC columns — the m² number quantity surveyors bill. The calculation implements A = 2 × (w + d) × h × n (perimeter × height, contact faces only) (IS 1200 Part 5 — formwork measurement). Formwork is measured on CONTACT area only — column tops and footing seats don't count. Beams: 2 sides + soffit; slabs: soffit only. CPWD norms allow 10–12 reuses of ply shuttering.

Frequently asked questions
What formula does the Column Formwork (Shuttering) Area Calculator use?+
It computes A = 2 × (w + d) × h × n (perimeter × height, contact faces only), per IS 1200 Part 5 — formwork measurement. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Formwork is measured on CONTACT area only — column tops and footing seats don't count. Beams: 2 sides + soffit; slabs: soffit only. CPWD norms allow 10–12 reuses of ply shuttering.
Does it include wastage?+
Yes — standard wastage/bulking factors are built in and stated in the formula line, so the quantity is an orderable number, not a bare geometric volume.
Is the Column Formwork (Shuttering) Area Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
