Why the use of bar charts is popular in the construction industry?

Bar charts are useful and used to detect the amount of resources needed for one particular project. Resource aggregation is done by adding resources vertically in the schedule. The purpose of this aggregation is to estimate the work production and establishing estimates for man-hour and equipment needed.
