Worth writing about
- A number that looks wrong. The most useful message we can get. Tell us the inputs you used and what you expected, and we will check the arithmetic against the published guidance.
- A calculator you need. If you are estimating something on a horse property and doing it on the back of an envelope, tell us what it is.
- A density figure from a real supplier. Our blended-footing assumption is an approximation. Real invoices make it better.
- Corrections to cited guidance. Extension publications get revised. If we are pointing at something outdated, let us know.
- Accessibility problems. If any part of the site is hard to use with a screen reader, keyboard, or magnification, that is a bug and we will treat it as one.
What we cannot do
We cannot specify footing for your arena, recommend a contractor, settle a dispute with a supplier, or act as an engineer. The calculators are a planning aid; the decisions and the liability stay with you and the professionals you hire. See the terms and disclaimer for the full position.
Privacy
There is no contact form on this site on purpose — a form means collecting data, and we would rather not. If you email us, we keep the message for as long as it takes to deal with it. See the privacy policy.
