Comparativo de prazos entre o sistema construtivo convencional e a construção a seco: estudo de caso creche tipo 2 padrão FNDE

Abstract

Conventional construction is the oldest and most widely used method in civil construction. It is a system in which the structures are molded in loco and that uses concrete, bricks and steel to be molded and assembled on site. Despite its wide use over the years, this construction system is very time-consuming and requires a high amount of resources and manpower, in addition to facing major problems such as efficiency and sustainability. In view of this situation, the dry construction system is presented, being an innovative approach that has been gaining popularity in recent years. In this system, the structures are assembled from prefabricated panels, modular elements and interlocking systems, eliminating the use of materials such as bricks and cement. With the continuous search for more sustainable and efficient systems, dry construction has been highlighted as an advantageous possibility for the future of the civil construction industry. Thus, in the present work, a time comparison between the conventional and dry construction systems was carried out, following the planning methodology of Mattos (2010) presented in his book that deals with planning and control of works. From this comparative study, whose object of study is the case of a type 2 FNDE day care center, it was possible to identify that the dry system presented 64.29% less time in relation to the conventional constructive system in the execution of the superstructure, 72.30 % less in the duration of the execution in relation to the fence and 69.89% reduction in the time of the total execution of the work.
