3D Modeller / Designer – Fire Fighting Systems

Job Summary

The 3D Modeller / Designer – Fire Fighting Systems will produce detailed 3D models, coordination drawings and fabrication information for firefighting and life‑safety 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 Responsibilities

1. 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
2. Coordination & Clash Resolution 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
3. Technical Compliance & Standards 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, cost‑effective modelling solutions
4. Production Support & Handover Support procurement and fabrication teams with model extracts, BOMs, cutting lists and spool drawings Provide site support during installation queries, producing revised details and as‑built models as required Handover complete model data and documentation to project teams upon milestone delivery
5. Continuous Improvement & Collaboration 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 post‑project reviews and share lessons learned to improve future modelling efficiency Requirements Education Diploma or degree in Mechanical Engineering, Building Services, BIM/CAD, or related discipline Experience 2–6 years’ experience in 3D modelling/BIM for firefighting, sprinkler and life‑safety systems or related building services Proven track record producing shop drawings, isometrics and fabrication information from 3D models Technical Competencies Proficiency in BIM and CAD software such as Revit, AutoCAD, Navisworks and relevant modelling plugins Experience with clash detection workflows, Navisworks Manage or similar tools Knowledge of firefighting systems: sprinklers, risers, hydrants, pumps, tanks and related fittings Ability to read and interpret mechanical, hydraulic and installation drawings and specifications Competence in producing BOMs, cutting lists and ISO drawings; familiarity with Excel for schedules and take‑offs What We Offer Opportunity to work on complex, high‑profile projects within a multidisciplinary team Professional development and training in BIM/CAD and fire protection systems Collaborative working environment with clear career progression
