12d Solutions

What 12d Solutions does

12d Solutions Pty Ltd is a privately held Australian software company, founded in 1988 by Dr Lee Gregory and Alan Gray, that develops 12d Model, a Windows-based civil engineering, surveying, and water engineering platform used across road, rail, land development, airport, mining, drainage, and environmental projects in over 65 countries. The product is built on a proprietary string-based data model with Super Alignments, Trimesh Objects, and Super Strings for metadata-rich 3D modeling, and is extensible through 20+ specialized modules (Survey, Detailed Alignment Design, Volumetrics, 12d Track, Urban Drainage, Sewer, Rivers and Flooding, RoadFlow, TUFLOW Interface, Pipeline, Visualisation, GIS, ADAC, BIM/Digital Engineering, 12d Field, Input/Output) layered on a 12d Model Base core. 12d Model supports open interchange via IFC, 12da/12dXML, LandXML, DWG/DXF, FDO-based GIS connectors, and integrations with TUFLOW, HEC-RAS, Revit, ArchiCAD, Tekla, VectorWorks, Navisworks, and Revizto.

The company monetizes through both perpetual licenses and monthly subscriptions, an annual maintenance program providing priority support and updates, and paid training delivered via certified partners plus a self-paced online platform (SPOT). Distribution is sales-led through wholly-owned subsidiaries in Australia (Sydney HQ), New Zealand (12d NZ Ltd, Wellington) and the UK (12d UK Ltd, London), augmented by regional resellers covering Australia (Extra Dimension Solutions), SE Asia, India (Voyage Technologies), and the Americas. Customer base spans large engineering consultancies (Arup, GHD, SMEC, AECOM) and government transportation agencies (Brisbane City Council, Transport for NSW, Roads and Maritime NSW, Queensland Transport and Main Roads), with 12d Synergy offered as a companion data management and worksharing product. The company has remained founder-controlled with no disclosed external funding, and continues to invest in standards-setting roles via founding membership in the Open BIM Alliance and active participation in BuildingSMART IFC development.

Scale indicators3 records

Recent moves6 records

Expansion highlights6 records

Direct peers

• Autodesk: Maker of AutoCAD Civil 3D, InfraWorks and Revit, the dominant civil engineering design and BIM platforms. Directly competes with 12d Model in road, rail, drainage and survey workflows but bundles civil tools inside a much broader AEC portfolio.
• Trimble: Trimble Business Center (TBC), Trimble Access and Tekla serve surveying, civil and structural workflows with tight hardware integration. Overlaps with 12d Model in surveying and field data collection (similar to 12d Field).
• Bentley Systems: Provider of OpenRoads, OpenSite, Power InRoads, GEOPAK and OpenRail for civil and rail design. Closest direct competitor in road and rail alignment modeling, going head-to-head with 12d on transport authority projects globally.
• Carlson Software: Carlson Survey, Carlson Civil and Carlson Mining are niche competitors to 12d Model with a similar focus on surveying, civil and mining workflows, often serving smaller consulting firms and individual surveyors.
• Topcon Positioning Group: MAGNET Collage, 3D-MC and Pocket 3D target the same surveying and civil construction markets. Competes with 12d on instrument integration and field-to-office surveying workflows.

Emerging players

• ZWSOFT (ZWCAD): ZWCAD is a low-cost DWG-compatible CAD alternative often paired with regional civil engineering extensions. Competes more on price and localization in emerging markets where 12d also pursues growth.
• Bricsys (Hexagon): BricsCAD is a DWG-based CAD platform increasingly used by civil and survey firms as a lower-cost alternative to AutoCAD. Indirectly competitive via the 12d Model CAD environment and IFC ecosystem.

Broad incumbents

• Dassault Systèmes: Through its 3DEXPERIENCE platform and Civil Design applications, Dassault targets infrastructure and civil engineering workflows. Overlaps with 12d in larger enterprise BIM and digital twin engagements but competes from a much broader PLM base.
• Hexagon AB (Leica Geosystems / Hexagon Geospatial): Through Leica Geosystems and Hexagon Geospatial, the company offers surveying instruments, ERDAS IMAGINE and GeoMedia for geospatial workflows. Competes in surveying-adjacent segments but is not focused on civil design authoring.

Regional players

• Civil Designer (Institute for Municipal Engineering of South Africa / Civil Software Solutions): Civil Designer is an integrated civil engineering package popular across Africa with road, drainage, water and sewer design modules. Comparable in scope to 12d Model but primarily serving the South African and Sub-Saharan markets.
