ALVENARIA ESTRUTURAL E DE VEDAÇÃO: Uma análise comparativa de custos de dois empreendimentos multifamiliar

Abstract

The present research aimed at a comparative analysis of costs in a multifamily residential project, using structural masonry and sealing methods. Due to the great market needs of imposing deadlines, we must be looking for new and practical constructive executions that meet both financially and efficiently. The construction system in structural masonry is one of the methods that corresponds to the needs of civil construction, minimum waste of materials, greater agility, guarantee of resistance against future pathologies, its piping is passed during the progress of the laying of the blocks, maximizing the time of execution . Finally, the advantages and disadvantages of its uses were presented. Making structural masonry a good choice of constructive method. The use of non-reinforced masonry is recommended whenever possible, as it is simpler to execute and provides greater savings. The choice of the type of structural block to be used is linked to several factors: level of aesthetic requirement, availability of existing blocks in the market, ease of handling on site, strength and types. Negative factor, the absence of structural walls in one direction compromises the supports for the slabs, it is not advisable to change internal walls, since its blocks have structural functions. The wood used in the masonry forms of sealing and the bricks of small dimensions, of low resistance employed, cuts in the walls contribute to the workmanship to be less productive the time of workmanship and generating more wastes during the course of the design. The need for specialized labor in the fence, such as: bricklayer, shipbuilder, carpenter, electrician, plumber and servant to perform the same tasks of the structural, and in the same, this establishment is reduced by the simultaneity of the execution stages, which induces the versatility of the worker through relatively easy training. On the other hand, the fence has a great freedom of conception of the architectural project, being able to conquer great gaps. Structural masonry is more feasible, in this case study, because it is more productive and is 18% more economical, but it has limitations for high ventures and can not have internal changes.
