ABSTRACT
The project effort represents the amount of work needed to bring the project to its completion. The number of heterogeneous specialists is related to the heterogeneity of a company's functionalities that are involved in the project. This is a primary variable since different functions often have different targets, different approaches and heterogeneous operating practices. The main objective of cost and schedule management in construction projects is the proper utilization of human resources, facilities, materials and funds to achieve a successful completion of the project with respect to the specific cost, time and technical performance constraints. An Estimate at Completion (EAC) and an Estimate to Complete (ETC) are regularly delivered to the customer at specified dates in order to provide an appraisal of the total expenditure of the project upon its completion and of the total expenditure for the work to be performed from the specified date until the project is completed.
