What is a bar chart (Gantt chart) in construction scheduling?

A bar chart (Gantt chart) displays project activities as horizontal bars along a timeline. Each bar shows activity start date, duration, and completion date. It provides easy visualization of schedule, resource allocation, and progress. Limitations include not showing dependencies between activities or critical path. Modern bar charts often include dependency links and progress tracking. They remain popular for communicating schedules to field teams and stakeholders due to simplicity.
