Job Introduction

Role

The BIM / CAD Technician is responsible for producing, updating and quality-assuring 3D models, 2D CAD outputs and associated model data across SCS JV assets. The role primarily supports Stage 5 construction and Stage 6 as-built model development using approved design, construction, survey and field-change information. The role also provides data development and automation support to improve model quality, validation and information delivery, working under the direction of the BIM Lead / BIM Coordinator and in accordance with SCS and HS2 BIM and CAD requirements.

Flexible working

We welcome you to ask about the flexibility you need. This might be part-time, remote working, or compressed hours for example. Anyone who applies for a role can ask about flexibility at interview. In return, we will explore what is possible for the role.

Main Responsibilities

• 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.

The Ideal Candidate

Required Qualifications & Skills

• Relevant technical qualification in CAD, BIM, digital engineering, software development or an equivalent level of demonstrable technical experience.
• Practical experience producing accurate 3D CAD/BIM models and 2D technical drawings or model-derived outputs.
• Experience interpreting drawings, mark-ups, technical requirements, survey or construction information and converting these into controlled graphical outputs.
• Strong attention to detail and a methodical approach to model and data quality assurance.
• Understanding of BIM through the design, construction and handover lifecycle.
• Understanding of model properties, metadata, structured data and information quality checking.
• Practical scripting or programming capability using Python, SQL or comparable technologies.
• Experience working within a multi-disciplinary project environment and communicating technical issues clearly.
• Commitment to continuing professional development and learning project-specific BIM, CDE and authoring standards. Desirable/Advantageous Qualifications & Skills
• Experience using Bentley and/or Autodesk BIM/CAD tools such as OpenBuildings Designer, MicroStation, Revit, Navisworks or Solibri.
• Familiarity with ProjectWise, ACC, iTwin and Common Data Environment workflows.
• Familiarity with IFC file types and schema, including mapping, conversion and validation between model formats.
• Experience working with large data sets, databases, APIs and ETL or data transformation/validation workflows.
• Understanding of BI requirements including data manipulation, analysis and visualisation, with Microsoft Power BI experience advantageous.
• Experience of parametric modelling, object/component libraries, complex assemblies or model-based technical production.
• Awareness of asset information, classification, model metadata, unique asset identifiers and BIM deliverables such as MPDT and DAC.
• Knowledge and awareness of survey methods, point clouds, red-line information and as-built model development.
• Experience within large, complex infrastructure, construction or rail projects.
• Awareness of PAS/BS1192 and ISO 19650 information management standards; relevant certification is advantageous.
• Experience of Python, SQL, REST APIs, web technologies or similar tools used to develop controlled internal data solutions.
