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?
An example of how a simulation that focuses on a 1 or 2 week period could be useful for planning on the specific route in which one detail needs to be constructed. For example, if columns need to be constructed in a spiral or some unique way, a simulation that focuses on the construction during this brief period could be useful.
What level of detail should be included in a 4D simulation?
- Should you include all of the elements in the building model?
I think all structural elements in the building model should be included in 4D simulation. I see 4D simulations being very useful to show different contractors, so things like furniture would not need to be included in a 4D simulation that will be shown to specifically the construction contractor. Then again, if plumbing or electrical elements are being installed in between moments of construction, I think it also makes sense to include these details in a 4D simulation being shown to the construction contractor.
How can model-based quantity takeoff improve the design process?
- How can designers improve their designs using the information provided by preliminary estimates of the cost of building their design ideas?
Designers can improve their designs using the information provided by preliminary estimates of the cost of building their design ideas by looking at the different material costs of the different structural elements. If the cost for one structural elements is egregiously high, then the designer will know what specific part of the design needs to be improved or a different, more creative look, needs to used to decrease the price.
