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.
