Frequently Asked Questions

Cimbra is a structural optimization platform for precast concrete design. It generates optimal designs for weight, cost, depth, or embodied carbon — all verified against ACI 318-19.

Cimbra is built for structural engineers and precast concrete manufacturers who need to quickly evaluate and optimize products during early-stage design and bidding.

Cimbra currently supports ACI 318-19. Eurocode 2 support is coming soon.

Cimbra is a computational tool intended for use by qualified professionals. All results are preliminary and must be independently verified by a licensed Professional Engineer (PE) before use in design, fabrication, or construction.

You configure and select molds from your library that represent your actual casting beds and manufacturing capabilities. Cimbra optimizes within each mold's geometry constraints, so results map directly to what you can produce.

Yes. In project mode, you define a table with different spans and loads. Cimbra optimizes each span independently using your selected materials and mold geometries producing a design matrix where the user can find the best designs for each span or designs that work efficiently for multiple spans.

The 30-day free trial includes full access to Cimbra's optimization platform, with restrictions on new mold design input and report export.

Cimbra is $250/month or $1,995/year per seat. Annual billing saves 34%. See our pricing page for details.

Cimbra generates professional PDF structural reports and CSV data exports. Reports include section drawings, reinforcement details, structural diagrams, and ACI 318 verification tables.

Yes. All data is encrypted in transit (TLS) and at rest (AES-256), stored in Google Cloud Firestore in the United States. Firestore security rules ensure you can only access your own projects. See our Privacy Policy for full details.
