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 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 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 costeffective 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 asbuilt 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 postproject 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

• 26 years experience in 3D modelling/BIM for firefighting sprinkler and lifesafety 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 takeoffs

What We Offer

• Opportunity to work on complex highprofile projects within a multidisciplinary team

• Professional development and training in BIM/CAD and fire protection systems

• Collaborative working environment with clear career progression
