OCNLR Level 3 Diploma in Building Information Modelling (BIM)

OCN-LONDON

vocational

This subtopic focuses on the practical application of BIM software to create detailed 3D building models, ensuring data-rich components and accurate geometry. Learners will also explore model management techniques, including collaboration and version control, and the methods to extract and publish project information such as schedules, drawings, and reports for project stakeholders. Mastery of these skills is essential for modern construction roles where digital coordination and information delivery are paramount.

What You Need to Demonstrate

Key skills and knowledge for this topic

Award credit for demonstrating accurate creation of a building model with correctly defined levels, grids, and building elements (walls, floors, roofs, etc.) in a recognized BIM software environment.
Evidence of effective model management must include use of worksharing or cloud collaboration features to coordinate with other disciplines, with clear version history and change tracking.
To meet the publishing requirement, the learner must produce at least one properly formatted set of construction documents (plans, elevations, schedules) exported from the BIM model, ensuring consistent naming conventions and data integrity.
Award credit for demonstrating proficiency in using industry-standard BIM software (e.g., Revit, ArchiCAD) to generate a building model with accurate geometry, grids, levels, and structural components.
Award credit for correctly implementing and managing a BIM model, including the setup of worksets, shared coordinates, and the use of object styles and view templates to maintain consistency.
Award credit for developing and publishing information that meets Level of Development (LOD) and data requirements, such as producing schedules, detail drawings, and exported IFC files with proper metadata.
Award credit for evidencing quality assurance processes, such as model audits for clash detection, adherence to the BIM Execution Plan (BEP), and the application of naming conventions.

Examiner Tips

Expert advice for maximising your marks

💡Always verify your model’s integrity by running clash detection and reviewing warnings before final submission; this shows proactive model management.
💡When publishing information, ensure you include a transmittal log or document register to demonstrate a structured approach to information delivery, as expected in industry standards.
💡Familiarise yourself with the specific BIM software's interface and shortcuts before the assessment; hands-on efficiency is often evaluated.
💡Always refer back to the project brief and BIM Execution Plan when producing outputs—marks are awarded for compliance with defined standards.
💡For publishing information, double-check that exported files (e.g., PDFs, DWGs, IFCs) match the required naming conventions and data structures.
💡Use model checking tools regularly during the task to identify clashes and data inconsistencies early, demonstrating professional diligence.

Common Mistakes

Pitfalls to avoid in your exam answers

Overlooking the setup of project base points and coordinate systems, leading to misalignment when models are shared or linked with other disciplinary models.
Failing to apply consistent object styles and naming conventions, which causes confusion during model management and when generating published outputs.
Neglecting to purge or audit the model regularly, resulting in bloated file sizes and performance issues, and potentially corrupt data when publishing.
Modelling without establishing correct project base points and coordinates, leading to misalignment when federating models from other disciplines.
Over-modelling or under-modelling elements relative to the required LOD, resulting in models that are too heavy to work with or lack necessary information for downstream use.
Neglecting to properly embed and verify non-geometric data, such as fire ratings, U-values, or manufacturer details, which compromises the 'I' in BIM.
Relying on 2D drafting overrides instead of accurately modelling in 3D, which causes discrepancies in schedules and drawings.
