Main Responsibilities
The BIM / CAD Technician is responsible for
- Produce and update 3D BIM/CAD models and model-derived 2D technical outputs in
project-approved authoring software, in accordance with the SCS BIM Execution Plan and
HS2 CAD Specification (HS2-HS2-IM-SPE-000-000006).
- Update models from approved inputs including design changes, field changes, NCRs, red-
line information, survey data and as-built records; raise discrepancies and do not introduce
unapproved design changes.
- Apply SCS modelling requirements for project coordinates, levels, naming, classification,
Level of Detail (LoD), Level of Model Information (LoMI), asset identifiers,
properties/metadata and model structure.
- Perform model QA and health checks, basic clash and coordination reviews, and support
federated model production and validation across disciplines and supply chain packages.
- Support native and IFC information exchange, model conversion and validation, checking
that geometry and property information remain complete and consistent following
translation.
- Ensure models and drawings are managed through the Common Data Environment
(ProjectWise / ACC) with the correct naming, revision, status, metadata and traceability.
- Support key BIM deliverables including the Data Acceptance Certificate (DAC), Model
Production Delivery Table (MPDT), model assurance records and graphical/non-graphical
information checks for Stage 5 and Stage 6 handover.
- Work with BIM Coordinators, engineering, design, construction, survey and the supply
chain to resolve modelling and information issues and keep model information aligned with
the approved construction status.
- Support controlled data development and automation using Python, SQL, ETL or similar
tools to improve repetitive model/data checks, extraction, transformation, reporting and
quality assurance.
