Cannot represent a bar chart.

It can't clearly reflect the complex interrelation among tasks, the key work and key lines that affect the construction period, the key of the whole project, and it's not convenient for schedule controllers to grasp the main contradiction.

Advantages of the bar chart: it directly reflects the sequence, start and end time, calendar time structure and project progress of each work.

Advantages of network diagram: it can clearly express the logical relationship between various tasks. The disadvantage is that drawing is very difficult and the workload of revision is very large, which requires higher users and makes it difficult to read drawings.

Precautions:

Because the bar chart is too simple, there is nothing to describe more complicated planning arrangements. The bar chart can't describe the complicated and mutually restrictive logical relationship among various activities in the project, which is often encountered when arranging large-scale project plans. Bar charts can clearly show the duration of work. According to relevant information, the bar chart is also called Gantt chart, which shows the activity sequence and duration of any specific project intuitively through the activity list and time scale.

Secondly, the bar chart can only describe the time sequence relationship of various activities in the project plan, and cannot reflect more other planning contents that the project planner or implementer pays attention to at the same time, such as the key activities that affect the total project duration.
