Concrete

In development

Slabs, footings, bags and rebar on the job — with the same engine and the same provenance as the website.

The app runs the same calculation engine as the calculators on this site, so a figure you get on the roof is the figure you would get at a desk — including the sources and assumptions behind it.

It is not available yet. There is no download and no mailing list; when it ships it will be linked from the apps page.
