BIM Modeler Rail
On-siteBengaluru, Karnataka, India
Job Summary
Develop and maintain rail discipline models for trackwork, alignments, earthworks, and structures to LOD 350, translating design inputs and survey data into accurate, data-rich 3D representations with defined system interfaces. Embed object parameters for quantity take-off and scheduling, then participate in federated model coordination to identify and resolve clashes between disciplines. Produce model-derived outputs including plans, sections, schedules, and visualizations while liaising with engineers and designers to ensure design intent is captured. Maintain model integrity within the Common Data Environment and support QA/QC checks to enhance modelling workflows. Deliver clean, standards-compliant models with minimal unresolved clashes for downstream construction use.
Required Qualifications
- Diploma or degree in Civil Engineering, Architecture, Construction, Geomatics, or a related field (or equivalent practical experience)
- Demonstrable experience as a BIM Modeller on rail or transport / linear infrastructure projects
- Proven track record delivering models to LOD 350, including modelled system interfaces and connections (not just standalone geometry)
- Solid understanding of BIM concepts: LOD/LOI, model federation, clash detection, and the ISO 19650 information-management workflow
- Strong knowledge of rail-specific elements: track geometry and alignments, turnouts/switches, ballast and sleepers, platforms, overhead line equipment, and corridor/structure interfaces
- Ability to read and interpret civil and structural engineering drawings and specifications
- Attention to detail, strong spatial awareness, and good coordination/communication skills
- Autodesk: Revit, Civil 3D, InfraWorks, Navisworks (clash detection / coordination)
- Bentley: OpenRail Designer, MicroStation, ProStructures / OpenBuildings (advantageous for rail projects)
- Familiarity with a Common Data Environment (e.g., BIM 360 / ACC, ProjectWise, or equivalent)
Desired Qualifications
- Experience across multiple LODs and understanding of model progression from LOD 200 → 350 → 400
- Exposure to 4D (sequencing) or 5D (cost) workflows
- Knowledge of relevant rail standards and authority requirements applicable to your region
- Experience producing or maintaining BIM content / family libraries
- ISO 19650 awareness or certification
- Point-cloud / survey data handling is an advantage
