Job Summary
The 3D Modeller / Designer – Fire Fighting Systems will produce detailed 3D models, coordination drawings and fabrication information for firefighting and lifesafety systems. The role involves converting design intent and specifications into accurate BIM/3D models, preparing shop drawings, and supporting design, procurement and site teams to ensure manufacturability, installation coordination and compliance with relevant codes and standards.
Key Responsibilities2. Coordination & Clash Resolution3. Technical Compliance & Standards4. Production Support & Handover5. Continuous Improvement & Collaboration
- 3D Modelling & Drawing Production
- Create and maintain detailed 3D models for firefighting systems including wet/dry risers, sprinklers, hydrants, pump sets, tanks and pipework using BIM/CAD tools
- Produce accurate fabrication and shop drawings, isometrics, splice and support details derived from models
- Ensure models include correct routing, clearances, hangers and coordination with other services
- Prepare layout and detail drawings suitable for procurement, fabrication and site erection
- Coordinate models with mechanical, electrical, structural and architectural disciplines to identify and resolve clashes
- Run clash detection sessions, document issues and implement agreed resolutions within the model
- Attend coordination meetings and present modelling progress and clash mitigation proposals
- Ensure designs and models comply with NFPA, BS and local authority requirements and project specifications
- Interpret design drawings, hydraulic calculations and manufacturer data to reflect correct component selection and arrangement
- Identify design inconsistencies or constraints and propose practical, costeffective modelling solutions
- Support procurement and fabrication teams with model extracts, BOMs, cutting lists and spool drawings
- Provide site support during installation queries, producing revised details and asbuilt models as required
- Handover complete model data and documentation to project teams upon milestone delivery
- Work closely with design engineers, estimators and project managers to align modelling deliverables with programme requirements
- Contribute to BIM standards, modelling templates and best practice for firefighting system workflows
- Participate in postproject reviews and share lessons learned to improve future modelling efficiency
Requirements
