10. Plan for the long term

1. Establish the model as the primary project document

• Define early that the 3D model will replace drawings as the contractual source of truth.

• Ensure model content is complete, accurate, and unambiguous.

• Embed all critical design information—geometry, attributes, specifications—directly within model objects.

• Structure the model logically so users can navigate and locate information quickly

Why it matters: A model-first approach only works when the information normally dispersed across drawings is fully integrated into the model.

2. Invest in model quality from the start

• Allocate additional time during early design stages to build a precise and detailed model.

• Validate geometry, object relationships, and metadata before issuing the model for tender.

• Maintain a clear naming and classification system for model elements.

Why it matters: Contractors must be able to reliably interpret information without referring to drawing sheets.

3. Use a shared digital environment for communication

• Adopt a cloud-based common data environment, such as Trimble Connect, to host, view, and discuss the model.

• Use shared views, screenshots, and object-linked comments to communicate queries and resolutions.

• Ensure all project partners—designers, clients, contractors—operate within the same environment.

Why it matters: A shared model builds a shared understanding. It reduces misinterpretation and streamlines issue resolution.

4. Maintain consistency across organizations

• Align on contractual expectations for a model-based tender.

• Define responsibilities for modelling standards, updates, and information ownership.

• Provide clear instructions on how the model governs over any supporting documentation.

Why it matters: When drawings are reduced or eliminated, clarity around roles becomes essential.

5. Support the workflow with clear processes

• Develop workflows for model review, communication, and issue tracking directly within the digital environment.

• Encourage teams to use model-based viewpoints rather than marking up separate documents.

• Standardise how screenshots, links, and comments are shared to maintain traceability.

Why it matters: Effective model-based collaboration depends on consistent processes, not just technology.

6. Recognise where 2D documentation still adds value

• Retain selected 2D outputs—such as profiles or linear geometry—where they genuinely improve interpretation.

• Use drawings as supporting information rather than primary contractual documents.

• Ensure any 2D views are derived directly from the model to maintain alignment.

Why it matters: Some engineering relationships remain clearer in 2D; hybrid support can strengthen understanding.

7. Use the model as a communication tool on-site

• Encourage site teams to reference the model during coordination meetings, inspections, and issue resolution.

• Share model links or viewpoints when clarifying questions remotely.

• Where connectivity or hardware constraints exist, provide preloaded local versions or simplified model sections.

Why it matters: Model-based discussion improves clarity and reduces rework even when live updates are not used.

8. Foster a culture of shared learning

• Acknowledge that many team members may be new to model-based delivery.

• Encourage openness, experimentation, and feedback throughout the project.

• Document lessons learned to support continuous improvement.

Why it matters: Cultural readiness is as important as technical capability when shifting to digital delivery.

9. Ensure compliance with standards and contractual frameworks

• Validate that the model aligns with national standards, classification systems, and legal requirements.

• Define how the model will be archived, referenced, and preserved as formal documentation.

• Engage legal and procurement teams early to align contractual frameworks with model-based workflows.

Why it matters: A model-only tender must meet technical and legal thresholds to stand as a contract.

10. Plan for the long term

• Treat each model-based project as part of a broader digital transformation journey.

• Document successes, challenges, and enhancements for future projects.

• Invest in training, modelling standards, and scalable workflows.

Why it matters: Model-based delivery becomes more efficient as organizations build experience and refine processes.
