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?
Simulations that focus on only a 1 or 2 week period are useful because they facilitate short-term planning in fast-paced environments. This could assist in simulating specifically how steel construction would be carried out, helping the different groups working on the project see how their work may overlap if precautionary measures aren’t taken; thus, improving coordination and minimizing the effects of last minute changes.
What level of detail should be included in a 4D simulation?
- Should you include all of the elements in the building model?
A 4D model should include larger elements that are used in the construction process, such as beams, walls, roofs, and other major elements. By excluding smaller elements, the model would be able to load faster and not become difficult to understand. If elements such as screws and bolts were included, the visualization could become difficult and not add much to an understanding of the project’s development. This level of detail should especially to earlier phases in project development, as the larger elements play a larger role. Once the project reaches further stages in develop, smaller elements become more relevant and could be detailed in a 4D model.
How can the feedback shown in a 4D simulation help you to optimize the project schedule?
- What are the main benefits of linking model elements to the project schedule?
By linking model elements to the project schedule, teams are more able to easily visualize project flow and coordinate to avoid scheduling conflicts. By avoiding two crews working on the same area at the same time, the efficiency of the project improves. Furthermore, linking model elements to a project schedule also creates a shared image for the whole team, which can improve a deeper understanding of the project and create more realistic schedules.
