BIM Modeller – 3D Coordination & Clash Resolution

Bradfield Robertson | Major Infrastructure Projects

About the Role

Bradfield Robertson is seeking an experienced and technically capable BIM Modeller / 3D Design Coordinator to support the delivery of infrastructure projects across Australia, including transport, airports, energy, roads, utilities and community infrastructure.

The successful candidate will be responsible for reviewing, coordinating and updating multidisciplinary 3D engineering models to identify and resolve clashes between building services, utilities, structural elements, foundations and other critical infrastructure.

Working closely with engineers, designers and project delivery teams, you will use Autodesk Revit, Navisworks and other BIM modelling and coordination software to identify design conflicts, develop practical engineering solutions and implement agreed modifications within coordinated 3D models.

This role requires more than simply identifying clashes. We are looking for someone who can understand the engineering implications of design conflicts, proactively investigate alternative arrangements and develop practical, constructible solutions that minimise impacts on surrounding infrastructure, design requirements and project delivery.

Key Responsibilities

- Undertake detailed 3D model reviews and clash detection using Revit, Navisworks and other relevant BIM software.
- Identify, assess and resolve clashes between mechanical, electrical and plumbing (MEP) services, structural elements, civil infrastructure, foundations, underground utilities and other project components.




- Modify and coordinate the positioning, alignment and routing of services and utilities to avoid conflicts with structural foundations, critical infrastructure and other design constraints.
- Develop practical clash resolution solutions in consultation with relevant engineering disciplines, considering constructability, access, maintenance, design standards and spatial constraints.
- Update and maintain accurate, coordinated 3D models incorporating agreed design modifications and clash resolutions.
- Prepare comprehensive clash detection and resolution reports, clearly documenting identified issues, proposed solutions, design changes, outstanding actions and resolution status.
- Coordinate with civil, structural, mechanical, electrical and other engineering disciplines to ensure integrated and consistent design outcomes.
- Participate in multidisciplinary design coordination meetings, providing technical input and recommendations to resolve complex design interfaces.
- Review model information for accuracy, completeness, spatial coordination and compliance with project BIM requirements.
- Support design development,



technical reviews and construction readiness activities through effective model coordination and issue resolution.

About You – The Ideal Candidate

We are looking for a proactive, detail-oriented BIM professional with strong 3D modelling capabilities and a practical understanding of multidisciplinary engineering design.

You will have demonstrated experience working with complex infrastructure or building services models and the ability to independently identify design conflicts, investigate alternative solutions and implement coordinated model updates.

Importantly, you will understand how different engineering disciplines interact and appreciate the implications of relocating services or utilities around foundations, structural elements and other critical infrastructure.

The ideal candidate will possess solid problem-solving skills, sound technical judgement and the ability to communicate design issues and proposed resolutions clearly to engineering and project delivery teams.

You will be comfortable working within multidisciplinary environments, managing competing design constraints and delivering accurate modelling outputs within project deadlines.

Essential Skills and Experience

- Demonstrated proficiency in Autodesk Revit, with experience developing, modifying and coordinating multidisciplinary 3D models.
- Strong working knowledge of Autodesk Navisworks, including clash detection, clash management and coordination workflows.
- Proven experience identifying, investigating and resolving clashes between MEP services, structural elements, civil infrastructure and underground utilities.
