BIM Designer - Rail

Job Description

We are seeking an experienced BIM Modeller with a strong background in rail infrastructure to produce and maintain high-quality, federated 3D models developed to LOD 350. The successful candidate will create discipline models in which elements are graphically represented as specific systems - with accurate quantity, size, shape, location, orientation, and defined interfaces and connections to adjacent systems - enabling reliable coordination, clash detection, and downstream construction use.

Key Responsibilities

• Develop and maintain rail discipline models (trackwork, alignments, earthworks, drainage, structures, stations, platforms, OCS/catenary, signalling and systems routing) to LOD 350, with modelled interfaces between systems suitable for clash detection and coordination.
• Translate design inputs - alignments, survey data, 2D drawings, engineering sketches and specifications - into accurate, data-rich 3D models.
• Apply project BIM standards, the BIM Execution Plan (BEP), naming conventions, and agreed Levels of Development / Information per the model progression schedule.
• Embed and manage object parameters and attribute data so models are usable for quantity take-off, scheduling, and asset information requirements.
• Participate in federated model coordination and clash-detection sessions; identify, log, and resolve clashes between disciplines.
• Maintain model integrity, version control, and revision history within the Common Data Environment (CDE).
• Produce model-derived outputs: plans, sections, schedules, quantities, and visualisations.
• Liaise with engineers, designers, BIM Coordinators, and other disciplines to ensure design intent is accurately captured.
• Support QA/QC checks on models and contributes to continuous improvement of modelling workflows and content libraries.

Qualifications

Required Qualifications & Experience

• 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.

Software Proficiency

• 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)
• Point-cloud / survey data handling is an advantage

Additional Information

Preferred / Desirable

• 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.

What Success Looks Like

Clean, coordinated, standards-compliant rail models delivered to LOD 350 on schedule, with minimal unresolved clashes, reliable embedded data, and outputs that the wider project team and downstream stakeholders can use with confidence.
