Piping Man-hours Estimation. Calculate man hours. Rough estimation of the order of magnitude (ROM) in the piping. In this post and the following, we will estimate the number of man-hours required to assemble the welded piping as shown in the figure using three calculation methods.
Working Time Calculation – Calculate man hours. Calculation of the labor required to execute a reinforced concrete base.
In this example, we are calculating the labor hours required to build a reinforced concrete foundation.
