Bentley OpenFlows StormCAD
Storm sewer analysis and design software now licensed as part of Bentley's OpenFlows Storm family. StormCAD remains the named storm-network design capability inside the current OpenFlows Storm packaging, focused on rainfall-to-outlet sewer design, hydraulic sizing, and CAD/GIS-connected stormwater workflows.
2.6 /5 composite score
Situational -- StormCAD is still the straightforward storm-sewer design tier inside Bentley's current OpenFlows Storm bundle, with strong CAD/GIS interoperability and public entry pricing, but it stays Windows-desktop-first and ties best into Bentley-heavy utility workflows rather than lightweight drainage tasks.

Alternatives in Civil & Infrastructure
AutoCAD-based civil engineering design and documentation platform for grading/surfaces, road and rail corridor modeling, pipe network hydraulics, and survey -- the civil-engineering flagship that turns conceptual InfraWorks models into construction-ready plan/profile sheets and quantity takeoffs.
3.4/5
Parametric BIM platform for advanced infrastructure design to build workflows -- extends Allplan Ultimate with integrated bridge structural analysis (AASHTO LRFD and Eurocode with national annexes), code-based reinforcement design and checking, parametric road/alignment modeling, 4D construction sequencing, and prestressing tendon modeling; supports all relevant file interfaces (IFC, BCF, LandXML, DWG, DGN, RVT, 3DM) plus Python API and Visual Scripting for automated workflows; part of the Nemetschek Group, with transparent published subscription pricing on the Allplan e-store.
3.4/5
Early-stage conceptual infrastructure design tool that builds a GIS-rich 3D context model (terrain, imagery, existing utilities) for rapid road, bridge, rail, and drainage concept design and stakeholder visualization before detailed design moves into Civil 3D or Revit.
3.2/5
Standard airport pavement thickness design software developed and distributed free by the U.S. Federal Aviation Administration (FAA) -- implements the FAA AC 150/5320-6G pavement design methodology using layered elastic analysis and the ACR/PCR pavement-strength reporting method; the mandatory tool for any U.S. airport pavement engineer working on FAA-funded airport projects, with companion backcalculation (BAKFAA) and runway-exit-design (REDIM) software.
