A public contact address has not been configured for this preview. You can still prepare and download an issue report from any calculator.

Report a calculation issue

  1. Open the calculator and reproduce the result.
  2. Choose “Download issue report” below the calculator. The report includes your current inputs, units, results, and warnings.
  3. Add what you expected and the source supporting that result. Review the file before sharing it.

Downloading a report does not send it anywhere. Do not include personal information or private project addresses.

Review process

Calculation corrections should be reproduced with a documented example and a regression test. Price suggestions should identify the location, date, specification, and scope of the quote. A calculator change is not an approval of a construction design.
