Health and safety with the model
How can the model help people build, maintain and change the building safely?
Designers decide most of the risks, the programme decides when people are exposed to them, and the handover decides whether future workers know. The model connects all three: see hazards in 3D, check the sequence in 4D, and attach what's left to the assets.
Understand
What it is, in plain language
- Pedia · WorkflowsDesign risk registerThe designers' record of significant health and safety risks in a design: how each was eliminated or reduced, and what remains for others to manage.
- Pedia · WorkflowsHealth and safety fileThe information the client keeps for anyone who later maintains, alters or demolishes a building: the residual risks and how to work safely with them.
- Pedia · GlossaryHandoverTransferring the completed works and their information from the delivery team to the client and operator.

Short lessons with a quick check
- Lesson · 3 min · quizDesigning out hazardsDesigners decide most of the risks people will face when building, maintaining and demolishing a building. The model is where you can see them, remove them, and record the ones left.
- Lesson · 3 min · quizSafe sequencing with 4DA 4D model shows not only when things are built but who is working where, and under what. Use it to find work stacked over other work, loads lifted over people, and edges left open.
- Lesson · 3 min · quizHealth and safety information at handoverThe people who maintain, alter and eventually demolish a building need to know the risks that were left in it. Tie that information to the elements in the model and the asset register, not to a binder nobody opens.

Tools that export Excel, PDF and Word
- Tool · Excel · PDF · Word3D IFC ViewerUse it to look at a model without installing software, or to show where requirements fail.
- Tool · Excel · PDF · Word4D SimulatorUse it to check a programme against the model before it goes to site, to show the sequence to the team, or to see where the job stands against the plan.
- Tool · Excel · PDF · WordAsset Register BuilderUse it before handover to see whether the asset data will work for the facilities team, or to start an asset register from the record model.
- Tool · Excel · PDF · WordCoordination Meeting PackUse it every week: agenda, attendance, issue log, actions and minutes.

The one I see most often on real projects: writing a warning on a drawing where the hazard could have been designed out. Tick off the checklist as you put each thing in place.
Common mistakes
What goes wrong most often on real projects.
- Writing a warning on a drawing where the hazard could have been designed out.
- Design risk registers that stop at construction and forget maintenance.
- Never looking at the 4D model for stacked work, lifts over people or open edges.
- Handing over safety information as one huge PDF nobody opens when the work is planned.
