Carlson Civil Suite

perpetual license (~$4,450 Civil Suite bundle); optional ~10%/yr maintenance; subscription option available Design the Building

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 composite score
Perpetual-license civil CAD suite for grading, roads, lots, and hydrology -- public perpetual pricing (~$4,450 bundle) and AutoLISP/.NET scripting via its AutoCAD/IntelliCAD engine give it strong interoperability (DWG/DGN/LandXML), though it is desktop-only with no REST API.

Alternatives in Civil & Infrastructure

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
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.
