Impacto da ABNT NBR 15575 na qualidade da construção civil

The quality in construction is increasingly a concern in this sector, in view of the occurrence of problems in civil works, even when a contractor is certified by ISO 9001. The ISO 9001 certification does not ensure the maintenance of quality because it only establishes the requirements for a quality management system (QMS) to ensure standardization of processes and products. With the development of ISO 15575, standard performance, the builders took on a quality parameter with the requirements established by this Standard, which must be met. Thus, the implementation of a quality management system (QMS) becomes essential, showing users the concern for quality. This study aimed to verify, through a case study, the impact of NBR 15575 quality construction and how that standard of performance may be the key element of ISO 9001 to ensure quality maintenance of civil works

Atualização do conceito de qualidade na construção civil

The quality control is of great importance for the development of any organization, mainly for providing an assurance of delivering high quality services and goods for the consumers. Quality can be defined by the word „change‟, for the company which intends to implement a quality control system must be open to changes. This can be noticed from the JURAN concept (1992 In SILVEIRA ET AL., 2002): “Quality is to fit for usage”, i.e., depending on the goal, the situation and the consumer, quality is seen in different ways, since each one has different wishes and opinions. Taking in to account the availability of means such as norms, theories and tools, that contribute for an efficient quality management system, this discrepancy of opinions and the lack of objectivity of this concept can be solved, since through the analyzes of these means one can set quality standards, i.e., market references which fulfill both consumers and builders demands. Thus, the quality concept ceases to be something so abstract, non-measurable, to become a more objective concept. Finally, the goal of this work is to analyze the quality concept through bibliographic studies and possible consumers‟ enquires, aiming at the building industry, and show how the quality, often taken as something abstract, can be a measurable and objective concept, that benefits both the consumer as well as the enterprise of this branch

Gestão de resíduos de demolição e da construção civil no município de Guaratinguetá-SP

The large volume of waste generated by construction and demolition has become increasingly a matter of concern to society. The handling and disposal of RCD's to gain prominence as over the years intensified the requirements for a sustainable world.

This study examines the methods used in waste management since he was not done any treatment to the present day. Presents comparative tables on the feasibility of installing a central crushing of inert waste and implementation of an inert waste landfill in the municipality of Guaratinguetá and Cachoeira Paulista. And yet the work being done by the city of Guaratinguetá reuse the material in class A in paving roads

Gestão da qualidade na construção civil

Quality Management has become an essential requirement for all companies intending to compete and ensure its place in the labor market. Several tools have been created as a way of ensuring the effectiveness of quality management, in order to control and manage the quality of services and products to ensure a final product with a high degree of competition and quality, besides satisfaction and exceeding customer expectations. Due to the great importance it has at the presente time on the world stage and internationally, civil construction felt the need to eliminate the defects and the lack of quality that have become so common over time to ensure a quality product and it´s customers satisfaction. It was then that this industry began to implement and develop more modern techniques and tools for quality control in construction. Quality achieved position in global market, defining which companies would continue and which companies would leave it, not to mention it became insistently required by the customer. Some tools such as ISO 9000 guided companies seeking a quality management. This presentation will present some of these management tools and their applicability in the civil construction industry. Thus, it will be evident that despite the current resources it is necessary that civil construction professionals abandon the idea that considers quality management a problem and begin thinking about it as a solution to prevent future errors and ensure the quality of their services

Avaliação de momentos fletores em estruturas de fundação tipo radier em concreto armado

It aims the comparison of these moments between an analytical plates theory and a computational numerical simulation. It is accented the details of studies about analytical theory as well the process, step by step, of a program that has as an influence the method of finite elements. The theory of plates has an extremely importance when it is talked about slabs and it takes as a base some fundamental hypotheses (that the middle point of the plate is considered flat and under formable) the points that are normal in relation to the middle surface is not considered because of its intensity that is irrelevant in comparison to the rest. The computational programs offer good results when they are applied in a correct way and, it resolves numerous functions in a short period of time. The objective is to highlight the importance of bending moments, its points of maximum and minimum, that has the objective of realize a good reinforcement sizing for a reinforced concrete. Furthermore, it can propitiate an economy in places that is demanded a small quantity of steel, before dimensioned for a load that is distributed in all the surface of the plate, at the same intensity
