Build on the calculation engine engineers already trust

Tap into the same engine engineers already rely on across Calcs.com, with validated, standards-aligned calculators. Add structural engineering capability to your product, without building the validation platform behind it.

How CalcsConnect works with you

Step 1
Send your inputs
Your product sends calculation inputs, project details, or site coordinates to CalcsConnect.
Step 2
Calcs.com runs the calc
CalcsConnect runs the same standards-aligned engine behind Calcs.com, checked against standards including ASCE 7, Eurocode, and NDS.
Step 3
Get results
Return loads, a pass or fail, and a signed-off PDF report, right when your user needs it.

Why partners build on Calcs.com

Your product, our verified engine

Calcs.com owns the engine, standards alignment, and updates. You own everything your users see. Every calculation you return is already checked against standards and proven in real engineering work.

Answers at the decision

Bring code-backed loads and pass or fail results into the workflow where decisions already happen. Users get the engineering answer before work moves downstream, not after.

Same paper trail, different front door

Reports generated through your software come from the same PDF pipeline engineers already use in Calcs.com. Your users get the calculation package they can review, share, and sign off on, without recreating the work in another system.

What you can build with CalcsConnect

Run calculations from your product

Trigger a calc and return the result backed by the standard it was checked against, without opening Calcs.com.

Get site design data from coordinates

Drop a pin and return design values for wind, snow, seismic, and other environmental loads supported by Calcs.com.

Manage projects programmatically

Create, organize, list, and link projects so calculation work stays connected to your users' workflows.

Generate signed-off PDF reports

Export the same calculation reports engineers already trust from Calcs.com.

Two ways to build

For software vendors

Add engineering answers your customers can defend, without owning the validation problem.

•Check model or drawing outputs against code
•Generate connection geometry, plates, bolts, and calculation outputs
•Add site-specific design loads to quoting or modeling workflows
•Return signed-off PDF reports from inside your product

For in-house development teams

Give the tools your engineers already build a foundation they can trust.

•Replace spreadsheet-based checks with validated calculators
•Automate repetitive engineering workflows
•Connect internal tools to Calcs.com project and report outputs
•Validate new automations against completed jobs already run in Calcs.com

Frequently asked questions

What is CalcsConnect?

CalcsConnect is the structural calculation API from Calcs.com. It lets other products run code-checked calculations, retrieve site design data, manage project workflows, and generate PDF calculation reports.

Who is CalcsConnect for?

It is for software vendors that need structural engineering answers inside their product, and for in-house development teams building their own tools, automations, or quoting workflows.

Does CalcsConnect replace engineers?

No. It removes duplicate work, manual lookup steps, and the need to rebuild calculation logic. Engineers stay accountable for the design.

Which standards does it support?

Calcs.com supports calculations and site data aligned to named standards including ASCE 7, Eurocode, and NDS.

Can partners generate reports?

Yes. CalcsConnect can generate the same PDF calculation reports produced by Calcs.com, including exporting a subset of sheets when users only need part of the calculation book.
