Aplicação da análise de valor agregado para o controle de prazos e custos em obras públicas
Descripción
Extension of deadlines and costs are common events in civil construction, especially in public works. Studies are carried out at different levels with the aim of developing methods and tools that contribute to the management in relation to compliance with the time and cost previously established. The present study aims to investigate the use of the Earned Value Management (EVM) method in the process that precedes the bidding, as well as in the stages of contracting and execution, offering support for taking preventive and/or corrective actions regarding the need for amendments to deadlines and costs. The work analyzed three infrastructure works already completed, which had extensions of deadlines and costs during their construction processes, applying the EVM method to them. The result of the analyzes obtained in this study indicates that the three works had the need for amendments to deadlines, costs, and contractual readjustments, in different periods of their construction, evidencing that there was not, on the part of the Public Administration, a preliminary analysis of the technical parts and of its feasibility in complying with the signed agreements. In the same way, the company that won the bidding process corroborated such preliminary information to the project management, both in the identification of the projected resources to be disbursed monthly and in the actual physical and financial progress, having in the application of the EVM a support for taking preventive actions, prior to the bidding process, as well as in the physical-financial management, during the execution, aiming at mitigating the need for contractual amendments.Nenhuma
