4D simulations are often used to show the construction sequence for an entire project, but shorter simulations that focus on a specific period of time are also useful.
Can you provide examples of how a simulation that focuses on a 1 or 2 week period could be useful for planning?
A simulation focusing on a 1-2 week period could be useful in situations where a specific stakeholder is focused on constructing one aspect of the building, for example, during the mechanical, electrical, or plumbing stage of the project. At that point, engineers wouldn’t need to see the entire simulation, but the timeframe that’s relevant to their particular work. Additionally, it might help to break up the simulation to understand in greater detail what needs to be completed in that specific timeframe, and that all previous elements have been completed appropriately before beginning.
What level of detail should be included in a 4D simulation?
Should you include all of the elements in the building model?
No, I don’t think you should include all of the elements in the building model. I think the level of detail should be as high-level as possible, while still maintaining the necessary information to plan for construction. This would be similar to how we prioritized and/or excluded design details in Module 4 for constructors vs. clients.
How can the feedback shown in a 4D simulation help you to optimize the project schedule?
The feedback can help you optimize the project schedule by linking tasks visually to what needs to be completed. This would highlight any inconsistencies or errors in planning, for example, if a slab on an upper level of your building is scheduled to be completed without the necessary structural columns or framing.
What are the main benefits of linking model elements to the project schedule?
The main benefits of linking model elements to the project schedule include the ability to plan accurately and limit any inconsistencies or errors, better collaboration and communication across different stakeholders, and the ability to experiment with the feasibility of different tasks being completed at different times.
