Creating a 4D Simulation
Who are the project team members that might be most interested in seeing the 4D simulation?
Team members responsible for planning and executing construction operations are most interested in the 4D simulation results. For example, the construction superintendent, contractors, and subcontractors.
Can you automatically map schedule tasks to search or selection sets in the composite model?
If you carefully match the names between the sets and the schedule tasks, automatic mapping is possible. The TimeLiner rules tab includes an option to Map TimeLiner Tasks from Column Name to Selection Sets with the Same Name. Using this rule, all items associated with a search set will be attached to the task of the same name.
What types of projects would receive the greatest benefit from creating 4D simulations to illustrate the construction process to the general public or governing officials?
Busy downtown construction sites where commercial and residential property owners will feel the impacts of the construction process on their daily routines are good candidates for 4D simulation. Also, transportation projects where major detours will be needed during the course of completing the project.
Identifying Time-Based Clashes
How do you model dynamic representations of temporary items - for example, work packages, ships, cranes, and other installation equipment? Can you perform a clash test that takes these moving work packages into account?
You could use the Animator window to create animation scenes with these objects, so that they will be moving around a project site, change their size, and so forth.
Since these moving objects could collide, soft clashing enables the automated checking of this. In a soft clash test, at each step of a scene sequence, Clash Detective checks to see if a clash has occurred. If it has, the time of the clash is logged, along with the event that caused the clash.
