Abstract: The earned value method (EVM) is a method that measures the amount of work actually done on a project. The purpose of this paper is to learn about the technique of the earned schedule (ES) as a tool additional to managing the schedule in construction projects, and observe its effectiveness compared to the EVM, and determine the amount of delay when the project does not finish on the planned date. The results on a real case have shown a difference between both these tools, when the project has finished the SV = 0 of the EVM. This represents the EV = PV = BAC, and the SV(t) of the ES represents a negative value. It indicates the amount of delay in the project; meanwhile, when the project has also been completed, the SPI = 1 indicates that the EV = PV = BAC and the SPI(t) of the ES can have different values from 1. This represents the rate of progress per period toward completion. Another difference is the SPI trend toward 1, which starts at 2/3 of the progress. The calculations made with the ES(t) on the SV and SPI are more reliable than the EVM, and the effectiveness of the ES(t) is observed in the projects with late completion.
