Also covers

Bentley OpenBridge Designer also appears in these sub-categories:

Structural Analysis
The structural placement is tied to bridge-specific modeling, analysis, load rating, and code-check workflows rather than general building analysis; C5 3/5 reflects Bentley-ecosystem integrations, and C3 2/5 reflects the specialized MicroStation-based workflow.

Alternatives in Civil & Infrastructure

Quadri (Novapoint)
Cloud-based civil infrastructure BIM collaboration platform enabling real-time teamwork on road, railway, tunnel, bridge, water/sewer design. Quadri provides central model storage; Novapoint provides design tools.
3.6/5
Carlson Civil Suite
AutoCAD/IntelliCAD-based desktop civil design suite (Carlson Civil, Survey, Hydrology, GIS) for grading, roads, lots, and hydrology. Sold as a perpetual license (Civil Suite bundle around $4,450) with optional annual maintenance and a subscription option. Scriptable via AutoLISP and .NET through its AutoCAD/IntelliCAD engine; reads/writes DWG, DGN, and LandXML.
3.6/5
Autodesk Civil 3D
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
Allplan Civil (Bridge)
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.
