Edit the Gantt Chart
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
Navigate to the project's Scheduling tool.
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.
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.
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.
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.
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
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).
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+2dto link to row 5 with a Start-to-Start relationship and 2 days of lag.
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.
