Escolha de sistemas de acesso a fachadas de edifícios verticais por processo de análise hierárquica (AHP)

Abstract

Civil construction has been significantly modernized in the last decades, technological advances include the evolution of knowledge, which results in a change from the empiricalartisanal scenario of formerly to a scientific-industrial reality (FILHO, 2009; RIBEIRO, 2009). For these changes to occur, the construction management system has been completely overhauled. Including the insertion of new management tools in companies and in the beds, involving all stages of the site (SOUZA, 2005). This work aims to apply the AHP hierarchical analysis process for choosing vertical facade access systems. In order to carry out this work a bibliographic research was carried out and a simplified comparative table was elaborated by the Hierarchical Process Analysis (AHP) method, with the definition of analysis criteria and the elaboration of weights coefficients for the quantitative evaluation of the equipment. The comparison was made between Scaffolding Fachadeiro and Rocker, as these are the most used systems in facade coatings. The comparison made, the Scaffold Fachadeiro presents 26% in points of advantages in relation to the Rocker. And it was also analyzed, even the Fence Scaffold presenting higher costs, it presents effective results in work safety. And they are advantages with respect to work safety, quality and productivity, which have a significant impact on the choice of equipment. Meeting the objectives, with the application of the scaffolding facade.
