Civil Calculator All-in-One

Civil Calculator All-in-One brings the calculations you actually run on site into a single, fast app — concrete volumes, rebar, earthwork, Eurocode checks and unit conversions. No connection needed. Built for civil and structural engineers, site managers, technicians, contractors and engineering students. MATERIALS • Concrete Volume — footing, slab, beam, column and wall, with waste factor, concrete weight and ready-mix truck count • Concrete Mix Design — simplified site method (Dreux) • Rebar Quantity — reinforcement ratio in kg/m³ • Rebar Pro (US/EU) — sections, spacing, estimation and reference tables • Bricks & Blocks — count per wall or partition • Mortar, Render & Screed — dosage and quantities SITE WORKS • Earthwork — cut and fill, swell factor, truck count • 3-4-5 Layout — squaring and setting out right angles • Slopes & Levels — slope percentage, angle, true length • Scaffolding — allowable loads per class EUROCODE CHECKS • Floor Load (EC1) — live loads by usage category • Beam Deflection (EC2/EC3) — allowable deflection check • Steel Column Base Plate — stress under the base plate • ULS/SLS Combinations — 1.35G + 1.5Q and other load combinations CONVERTERS • Force and Weight — kN, tonnes, daN, kg • Pressure and Stress — MPa, bar, psi, N/mm² • Volume and Mass — m³ to tonnes for concrete and steel • Metric and Imperial — m, cm, mm to ft, in HISTORY & PROJECTS • Save any result and find it again later • Group your calculations by project • Export to PDF and share straight from the app WHY IT STAYS ON YOUR PHONE Works offline. Every calculation runs on the device, so a basement, a tunnel or a remote site is no obstacle. Shows its working. Each result lists the intermediate values — net volume, waste, total, weight — not just a single number you have to trust. Bilingual. English and French, switched in one tap. Comfortable to read. Light and dark themes, tuned for bright sunlight and for the site hut. No account, no sign-up. Civil Calculator All-in-One is a calculation aid intended for preliminary sizing and on-site verification. Results should always be reviewed and validated by the engineer responsible for the design.
