The Earned Value Management (EVM) method is not very common in the construction industry. Large companies have developed their own information systems, because EVM is not adapted to the specific economic model of this sector, and small businesses and professionals are unaware of it. This paper develops two different applications of the EVM method: a simplified model, for the professional in charge of supervising the execution of the works, based on the available information, and a more complex model, targeted to the small construction company, since its cost management system must integrate actual and estimated cost with revenues. Models have been implemented in Presto, software widely used in construction, suggesting the necessary changes so that professionals and small businesses get all the EMV results from data that they already use in their tasks. The goal is to replace a passive point of view, limited to record what is happening in the works, by an active strategy enabling them to take decisions and anticipate to possible deviations from cost and time.
