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.”

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.”

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.

Most engineers run Calcs.com alongside Tekla Tedds on a new project first. Full adoption typically happens within a few weeks.
