4D Planning

Searching...
    Go to advanced search
    In 4D planning, this refers to the ability to incorporate and simulate schedules and construction processes into a model. This provides a better basis for alternative planning and construction processes, better control over construction progress, faster billing, and a clearer overview of on-site operations, thereby improving the coordination of site setup and logistics.

    Option 1: Using MS Project

    • Create processes

    Option 2: using a CSV file

    • Select template file: "Schedule(Excel)_TEMPLATE.xlsx"
    • Create activity types (predefined; additional types can be added)
    Activity Type/Process TypeWhat happens to the element
    ConstructionCreated elements
    Abortcancelled elements
    TemporaryTemporary elements
    • Each process should be on a separate line (e.g., "Build ground floor walls, replace existing ground floor doors," etc.)
    • Specify dates
    • Save as .csv
    • Open with a text editor
    • Replace all ";" with "," (under Edit -> Replace)
    •  Save as .csv

    Create and define Revit parameters

    If the required 4D_... parameters have not already been created and defined in the template, they can be loaded into the project from the shared parameter list and assigned to the appropriate categories.

    The activity hierarchy must be recreated the first time; after that, it will only be synchronized.

    Simulate and export

    • Check whether the simulation is correct.

    Animation (Optional)

    • Open Animator
    • Create each process to be simulated
    • Create a keyframe at 0:00 and 0:05.00. A diamond will then appear at the beginning and end, respectively.
