The problem
The big suites force you into a do-everything platform you don't need.
You rebuild the same shear-wall spreadsheet on every project. SolidCalcs is just the residential calcs you actually run — done right, ready to stamp.
The tools
The high-frequency residential workflows
Each tool outputs a clean, stamp-ready calculation package. No spreadsheet archaeology.

Why SolidCalcs
A tool engineers rely on
Code-current, always
Built to ASCE 7-22, CBC 2025, NDS, AISC 360, and NAAMM FP 1001 — updated as codes change.
Clean, stamp-ready output
Defensible calculation packages with clear assumptions, references, and demand/capacity ratios.
Built by a practicing engineer
Designed around the workflows you actually run on residential projects — not a generic platform.
Far cheaper than the big suites
Pay for the calcs you use. No five-figure all-in-one license for tools you'll never open.
