Tedds produces calc sheets. Calcs.com manages the whole design.
In Tedds, each calculation is its own document. When a load changes, you open every affected sheet and update it manually. Calcs.com connects members through a live load path - change a roof load and every linked beam, column, and footing recalculates. Engineers who move from Tedds typically run the same project in half the time once they stop managing individual files.
The software has made us a minimum of 30% more productive. It's eliminated at least 30% of the workload.

Calculation reports reviewers actually want to read
Tedds outputs Word documents that need formatting before they go to a client or AHJ. Calcs.com exports clean, structured PDF calc packs that include project metadata, code references, and member summaries. Reviewers can follow the logic from first principles without a formatting pass from the engineer who ran the calc.
Doing the design in Calcs.com and being able to export the printout means our calculations are legible and easy to follow for reviewers.

One workspace for the whole team, on any device
Tedds is a Windows desktop tool. Calcs.com runs in a browser on any machine - no IT ticket, no install, no license provisioning. An engineer can start a trial on their own and run a real project before raising it with their principal or IT team. Once the firm adopts it, project defaults are set once and shared across the team, so junior engineers work from the same code editions and load assumptions as principals, with no stale template files circulating by email.

What engineers say
Yes, it costs money, but you spend money to make money, and the money you make is based on the time you save.
Matt Ward
Principal Engineer
I like that Calcs.com shows the code reference section for each calculation and function. That means every time I use it, there's a potential for me to learn something.
