Electrical BIM Modeller

Key Responsibilities: 

• Develop, update, and maintain detailed 3D BIM models for electrical systems including:  

• • Power distribution (HV/MV/LV) System 

• • Earthing & bonding (E&B) for rail systems 

• • Cable tray/containment and conduit routing in stations, tunnels, and depots 

• • Fire alarm, public address, CCTV, access control, SCADA interfaces 

• • Traction power room interfaces (TSS/ATSS/SSP/PRS) where applicable 

• • Signalling system along the line  

• • Other rail system assets within the rail environment  

• Produce coordinated drawings (plans, sections, elevations, schematics, SLDs, containment layouts) as per project requirements. 

• Collaborate with architecture/structural/mechanical teams, railway systems engineers, and BIM managers for:  

• • Clash detection & resolution 

• • Model integration 

• • Interface coordination (Rail System & others) 

• Follow project BIM Execution Plans (BEP), modelling standards, naming conventions, classification systems, and documentation protocols. 

• Ensure model structuring aligns with ISO 19650 workflows. 

• Perform model audits and ensure model integrity throughout all stages of design. 

• Maintain version control and ensure accuracy, completeness, and consistency. 

• Generate equipment schedules, cable quantities, and BOQ inputs when required. 

• Attend design and BIM coordination meetings. 

• Support model-based discussions with engineering teams and stakeholders.  

• Prepare as-built models and digital handover documentation compliant with client and operator standards.  

• Assist senior engineers and BIM coordinators with workflow improvements, template development, and best practices for electrical BIM delivery.
