Common questions
Before you send a note.
The fastest route to a useful answer is a reproducible example.
Are these tools approved for construction documents?
No blanket approval is claimed. The utilities are reference tools for preliminary checks. The responsible professional must verify assumptions, criteria, code requirements, manufacturer information, and required precision for the project.
Does the site save calculator inputs?
No. The public calculators run locally in the browser and do not send or save values to Dickson Engineering. Review the privacy notice for details about ordinary web hosting and email contact.
Can I request another calculator?
Yes. Describe the recurring task, who performs it, the inputs and outputs, and how the result is currently checked. Use the product feedback form.
I found an accessibility barrier.
Email jeremy@dicksonengineering.com with the page, device, browser, and the task you could not complete. Dickson Engineering will work to provide the information or function in an accessible form.
