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.
Focusing on a smaller time period for 4D simulation could be useful for making sure that the work done in that time is fully understood by the construction team. For example, we might want to make sure that the electrical system is viewable as a whole while that is being installed. This keeps the project on track and can also make the project schedule more specific and measurable.
What level of detail should be included in a 4D simulation?
Enough detail to get an overview of the building. Making a simulation of a model, you may want to focus on structure, in which case you shouldn’t include details beyond the foundational elements. In other cases, you might want to show a client a 4D simulation in which you would want it to appear aesthetically pleasing and get them excited. Or, you may be wanting to highlight a specific area to have your client choose between options, in which case that part would be emphasized in the simulation, with more detail.
How can model-based quantity takeoff improve the design process?
This can give you an idea of how much material is going to be needed for the project, and allows for time within the design process to alter structures or materials or amounts to fall within a stricter budget. It could also show you that you have more room to work with, and can enhance designs if need be.
