Module 9 - Points to Ponder

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.

• A simulation of only a few weeks can be helpful in showing specific stages in greater detail. For example if a specific crew, like framers, are present to work on the building, it could be beneficial to have a 4d simulation detailing the work necessary by them during their time working on the project, showing in detail the stages of their specific trade.

What level of detail should be included in a 4D simulation?

• No the 4d simulation is not meant to include all details. It is intended to show the construction stages of the structure, so only structural and key elements should be included. It would be unnecessary to include elements like furniture or windows.

How can the feedback shown in a 4D simulation help you to optimize the project schedule?

• the feedback shown in the 4d simulation can help optimize the schedule by helping figuring out which tasks need to be done in which order. It shows the building at every stage of construction, so it will help to highlight errors in how the stages are arranged.
