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

1. 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

1. 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

1. 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

1. 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
