SiteForge: Construction Calc

Every civil and construction calculation you actually use, in one app that works with no signal.

No account. Nothing you calculate leaves your phone.

SET YOUR UNITS ONCE
Pick metric or imperial at the start and every calculator opens that way. When one field needs something else — a thickness in millimetres, a bar in inches — change that field alone and the app tells you it has done so. No hunting through a dropdown on every line.

THE CALCULATIONS A SITE ACTUALLY NEEDS
Concrete slabs, beams, columns, footings, walls, tanks and pipes. Cement, sand and aggregate from any mix ratio. Brick and block walls with openings and mortar. Plaster, paint, tile, adhesive and grout. Excavation, filling, truck trips, asphalt and road gradients. Rebar weight, slab and column schedules, stirrup and helix cutting lengths. Beam reactions, moments and deflections. Formwork contact area. Soil relations. Roofs, stairs, pools and tanks. Area, volume, material weight and seventeen unit converters.

IRREGULAR PLOTS WITH MORE THAN FIVE SIDES
Enter up to fifty coordinates, reorder them, and get the area, the perimeter and the centroid. If the outline crosses over itself the app says so instead of handing you a confident wrong number. Most calculators stop at four or five sides; this one does not.

EVERY RESULT SHOWS ITS WORKING
Tap Formula and notes on any calculator and you get the equation, what each symbol means, and the assumptions behind it. That panel is free on every calculator, including the paid ones, because a number you cannot check is a number you cannot use.

PROJECTS, HISTORY AND FAVOURITES
Star the tools you use daily and they sit on the home screen. Every calculation is kept so you can reopen it with the same numbers. Group them under a site or a client, add a note, and share a result as plain text to anyone.

BUILT FOR A PHONE ON A BUILDING SITE
Every calculation runs on the device. No signal, no problem. Dark mode for a site office, large tabular numbers for a bright afternoon, and a layout that uses the whole screen on a tablet.

FREE FOREVER, NOT A TRIAL
• Every quantity, area, volume, material weight and unit conversion calculator
• The formula and assumptions behind any calculator you can open
• Sharing a result as plain text
• Exporting everything you have saved
These do not move behind payment. If a Pro subscription ever lapses, Pro features lock and your data never does: every project and every saved calculation stays exactly where it is.

SITEFORGE PRO
Advanced RCC and bar bending schedules, structural beam and column analysis, soil mechanics, superelevation and curve tools, cost estimation, custom materials and prices, PDF and CSV export, and unlimited projects, history and favourites. Available as a yearly subscription or as a single lifetime purchase that never expires.

TWENTY LANGUAGES
English, German, Spanish, French, Portuguese (Brazil), Italian, Dutch, Polish, Turkish, Swedish, Indonesian, Vietnamese, Russian, Ukrainian, Hindi, Thai, Japanese, Korean, Chinese (Simplified) and Arabic, with full right-to-left support.

SiteForge is a calculation tool, not an engineering design service. Every figure is an estimate worked out from the numbers you enter, and you are responsible for checking both. It does not replace a licensed engineer or your local building codes, and structural, foundation and soil results in particular should be verified by a qualified professional before anything is built.
