Scheduling and 4D Simulation

BIM for Architecture, Engineering, and Construction Curriculum

Exercise 5.3.1: Creating a 4D Simulation

In this exercise, students will learn how to:

  • Link a schedule file to the TimeLiner tool and generate the hierarchy of tasks.
  • Create selection sets and search sets to facilitate linking model elements to the schedule tasks.
  • Specify simulation settings and run a 4D simulation.

  • Continuing from the point where the tutorial left off, creating additional search and selection sets to select groups of model objects between Level 2 and the Roof level. Each set should contain the elements to be mapped to a specific task in the construction schedule.
  • Use the TimeLiner tool to attach the sets of objects to their associated schedule tasks.
  • Run a 4D simulation of the construction schedule. Modify the playback duration and interval size to achieve the desired visual effect for effectively sharing the simulation with others.

Exercise 5.3.2: Identifying Time-Based Clashes

In this exercise, students will learn how to:

  • Reveal a time-based clash by linking a clash test to the project schedule.
  • Add schedule tasks to accurately reflect the existence of temporary construction objects, and attach model geometry to that task.
  • Run a time-based clash test to confirm the elimination of the time-based clash.
  • Run a 4D simulation that includes the appearance and disappearance of temporary object to the project.

  • Use the project schedule to determine the date by which the material lift must be removed in order to avoid interfering with the installation of the building stair.
  • Modify the schedule task linked to the materials lift so that it reflects the required installation and removal dates.
  • Perform a time-based clash test between the Construction_Equipment and the Architectural_Shell models to confirm that a clash no longer exists between the materials lift and the stair. Be sure to link to the TimeLiner when you run this test in the Clash Detective tool.
