Monitoring time and costs has been traditionally served as a basis for control of construction projects; this is because one of the main causes of legal conflicts derived from a construction contract is the breach on delivery time of the project, and because the main goal of a construction firm is to get a profit that it considers appropriate. In the late nineteenth century, Frederick Taylor laid the foundations in order to ascending the management to the category of science, and through engineering techniques he changed the paradigms of productivity in industry. After several decades of research on project management the Earned Value technique was developed, which allowed control the execution of a project through its budget and its schedule; and in the early twenty-first century took another step in how to make a project assessment for performance of time, through Earned Schedule technique. The aim of this study was to evaluate the effectiveness of two project management methods: Earned Schedule and Earned Value; to control the time and cost in construction projects executed in Mexico. For achieving this, time and cost performance indicators and predictors from six projects were calculated. Results showed better performance in projects using the method of Earned Schedule to control the time; and independence between the performance indicators of time and cost.
