Construction projects frequently need to use overtime and overmanning to get work done on time. Overtime and overmanning often appear concurrently, especially when acceleration has been ordered. However, the calculation of the number of workers required for overtime and overmanning is often left to the experience and judgment of the foreman or superintendent. Whereas the overtime and overmanning estimate of superintendents and foremen is sometimes correct, it is sometimes incorrect also. The reason is that factors such as efficiency loss are not taken into account in an objective manner. More pertinently, calculations for efficiency loss are often not normally performed on job sites when overtime and overmanning must be designed. When we really delve deeply into the problem, we see that calculation of overtime with overmanning is a lengthy process involving iterations. Using a sample problem, this paper demonstrates how overtime and overmanning should be objectively and correctly designed using standard charts prevalent in the industry.
