The Gantt chart is a widely-used tool for tracking deadlines and schedules during construction projects. It visually represents the project timeline, showing tasks along a horizontal time scale. Each task is represented by a bar, with the length of the bar indicating the duration of the task and its position on the timeline showing the start and end dates. This makes it easy to identify overlapping tasks, dependencies, and critical deadlines.

In construction projects, where timing is crucial for coordination among various stakeholders and trades, Gantt charts allow teams to manage schedules effectively, ensuring that all tasks are completed on time. Their visual nature assists in communicating the progress of the project to all involved, making it a preferred choice among project managers and interior designers.

The other options, while useful in their own contexts, do not serve primarily to track deadlines. A milestone chart focuses on key events or milestones rather than the detailed timeline of each task. The budget relates to financial aspects of the project rather than scheduling. A CPM chart, or Critical Path Method chart, is a more complex scheduling tool that emphasizes task dependencies and critical paths but may not be as straightforward or visually intuitive as a Gantt chart for everyday project tracking.
