Background

Procore’s Gantt chart is interactive, allowing you to make real-time adjustments without typing data into the table. This visual approach is often the fastest way to refine a schedule or look-ahead. In an editable schedule, Procore dynamically updates the logic chain as you move or resize bars.

Things to Consider

  • Required User Permissions: 'Standard' level permissions or higher on the project’s Scheduling tool.

  • Note: In a Read-Only master schedule (Option 1), these graphical edits are only available within the Look Ahead tab.

Steps

  1. Navigate to the project's Scheduling tool.

  2. Adjust Activity Duration:

    • Hover your mouse over the right edge of an activity bar until the cursor changes.

    • Click and drag the bar to extend or shorten its length.

    • Note: The table will instantly reflect the new duration in days.

  3. Update Activity Progress:

    • Locate the white arrow at the bottom of the colored activity bar.

    • Click and drag the arrow to the right to increase the percent complete.

    • Note: The shaded portion of the bar represents the work finished.

  4. Change Activity Dates (Drag-and-Drop):

    • Click and hold the center of a activity bar.

    • Drag the bar horizontally to a new start or finish date and release.

    • Important!: If you move an activity accidentally, click the Undo icon instead of re-dragging the bar to its previous position.

  5. Draw a Dependency:

    • Click the circle at the end of a predecessor activity bar.

    • Drag the connection line to the beginning of the successor activity bar to create a Finish-to-Start dependency.

  6. Edit Lag via Connection:

    • Double-click the dependency arrow connecting two activities on the Gantt chart.

    • Enter the desired lag time and click Save.

Advanced Gnatt Editing

  1. Pin Successors (Move without Shifting):

    • Hold the Ctrl (Windows) or Cmd (Mac) key while dragging an activity bar on the Gantt chart.

    • This allows you to move the activity or change its duration without shifting its successors (automatically adding positive or negative lag).

  2. Use Relationship Shorthand:

    • Instead of using the modal, click into the Predecessor or Successor columns in the grid.

    • Type the shorthand code: [Row ID][Type][Lag].

    • Example: Type 5SS+2d to link to row 5 with a Start-to-Start relationship and 2 days of lag.

  3. Deactivate Dependencies:

    • Double-tap a dependency arrow on the Gantt chart.

    • In the modal, select Deactivate.

    • Note: Deactivated links appear as dashed lines and no longer drive schedule logic.
