Adoção de práticas da produção enxuta na construção civil

The civil construction sector has been stimulated to industrialize itself by the adoption of lean production practices in its constructive process. Given this fact, this research verify and identify good practices and difficulties in implementing lean production in construction companies in the State of São Paulo, in order to be able to formulate recommendations to potentiate the performance of the lean concepts applied. The research method used was a multiple case study, where the companies analyzed are constructors that have already initiated the lean application in their systems. From the results, a case analysis was conducted in order to note the constructors' situation in relation to lean construction and, base on this analysis, recommendations were proposed for the companies reflect on lean principles and apply them along to your construction management

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

Estudo da reutilização de materiais reciclados em obras de construção civil

This graduation project aims to study and analyze the reuse of solid waste projects in Civil Construction, checking the different factors such as economic viability, production processes, classification of the main materials, advantages and disadvantages, always seeking to guide themselves according Brazilian legislation establishing criteria for Waste Management of Construction. In addition, points are studied that prevent the expansion of recycling construction waste. It also offers needs improvements to the implementation of recycling to be carried out on a more expressive than current

Considerações sobre o gerenciamento da construção civil em obras residenciais verticais

The civil construction is an industrial sector of great economic importance and that it comes exponentially growing in the country. However, this activity is deficient in its management processes, and in this context that the management of construction as a way of organizing and controlling all the technical and construction of an enterprise. The literature shows that the manager has a key role throughout the process of planning, execution and analysis of the results of the work being of prime importance that all steps have its due attention in order to avoid any technical problems or lack information. The management’s main objective is the transparency of technical and financial information to investors and their assessments of physical and financial performances of the work intervened positively in quality, deadlines and costs. In this sense, this paper aims to present consideration about the proper management of a residential development in vertical construction

Importância da avaliação do ciclo de vida na análise de produtos: possíveis aplicações na construção civil

Much has been discussed lately about reusing waste in new construction materials and countless studies have been carried out based on this objective. However, before these products can be called “sustainable” and a recycling system can be effectively implemented, it is fundamental for all the aspects involved in this action to be understood, and more important, what are the true gains for the productive sector and what are the benefits for the environment if this was to occur. In order to obtain a general framework for all environmental aspects and potential impacts associated with these products, over their entire life cycle, the most appropriate methodology is the Life Cycle Assessment (LCA). In view of the above, the objective of this work is to provide an overview of current studies of LCA, its history, its importance, its standards and the methodology employed and its applications related to civil construction. It is expected, to obtain a more complete scenario of the influences from a study of LCA, as well as establishing a contribution for the assessment of specific products and processes for civil construction, disseminating the importance of the use of this tool within the sector.

Physical and mechanical characteristic of particleboards produced with residues of sugarcane and stem leaves of bamboo bonded with castor oil adhesive

In this research the aim was produce a particleboard with alternative materials and evaluated its physical and mechanical characteristics. The raw materials used are residues from sucarcane bagasse (SC) (Saccharum officinarum) and stem leaves of bamboo (B) (Dendrocalamus giganteus), bonded with a bi component adhesive based on castor oil. It was produced particleboards with five different traces: 100% SC, 75% SC+25% B, 50% SC+50% B, 25% SC +75%B and 100 % B. Their physical and mechanical characteristics were evaluated accordingly to Brazilian standard NBR 14810-3. Regarding the results obtained, it can be detached that for physical and mechanical evaluation it is evident a negative relation among the amount the sugarcane bagasse and their physical and mechanical characteristics, that is particleboards with low concentrations of sugarcane bagasse had better results. However all particleboards could be recommended for use as sealing particleboards in the segment of civil construction.

Benefícios na execução de uma obra sustentável em contrapartida aos métodos tradicionais da construção civil

The civil construction sector in Brazil is, simultaneously, a necessity that drives the economy and an evil that degrades the environment. Simple choices adopted in an enterprise can make big difference in harm caused by constructive practices, minimizing its harmful to the environment and making it sustainable. These choices, however, involve the use of materials and techniques often unknown by the builders, since the construction industry is very traditional. Even worse, the eco-friendly materials and sustainable techniques also face another obstacle to its use: the prejudice. Builders and customers prefer traditional methods to sustain belief that they present lower quality and higher price. This work raises awareness of the urgency with traditional methods must be overridden, showing practical and simple ways for this replacement, as well as confirm the quality equal to or even higher in the use of alternative materials and techniques, without addition in cost. Thus, the benefits are generated for all parties involved, from builders to residents

The use of software Mapavox for teaching graphics and games to blind and low vision students: a development through practices

Current policies on education to visually impaired point for a growing trend of including students with special educational needs in regular schools. However, most often this inclusion is not accompanied by an appropriate professional trained or infrastructure, which has been presented as a big problem for regular school teachers who have students with visual impairments in their classroom. Based on this situation, the Group of Extension in Tactile Cartography from UNESP - University of the State of São Paulo - Campus de Rio Claro - SP - Brazil has been developing educational material of geography and cartography to blind students at a special school. Among the materials developed in this study highlight the development of graphics and board games provided with sound capabilities through MAPAVOX, software developed in partnership with UFRJ - Federal University from Rio de Janeiro - RJ - Brazil. Through this software, sound capabilities can be inserted into built materials, giving them a multi-sensory character. In most cases the necessary conditions for building specific materials to students with visual impairments is expensive and beyond the reach of features from a regular school, so the survey sought to use easy access and low cost materials like Cork, leaf aluminum, material for fixing and others. The development of these materials was supported by preparation in laboratory and its subsequent test through practices involving blind students. The methodology used on the survey is based on qualitative research and non comparative analysis of the results. In other words, the material is built based on the special students perception and reality construction, not being mere adaptations of visual materials, but a construction focused on the reality of the visually impaired. The results proved were quite successful as the materials prepared were effective on mediating the learning process of students with disabilities. Geographical and cartographic concepts were seized by the students through the technology used, associated with the use of materials that took into account in its building process the perception of the students.

The position effect of structural Eucalyptus round timber on the flexural modulus of elasticity

A madeira roliça possui grande emprego nas construções civis, desempenhando a função de vigas, colunas, fundações, postes para distribuição de energia elétrica, entre outras, apresentando a vantagem de não ser processada, como é o caso da madeira serrada. O projeto envolvendo elementos roliços requer, além de outras variáveis estruturais, o conhecimento do módulo de elasticidade. No Brasil, os documentos normativos que tratam da determinação das propriedades de rigidez e resistência para peças roliças de madeira estão em vigência há mais de vinte anos sem revisão técnica. A madeira roliça, por geralmente possuir eixo com curvatura não nula, pode apresentar, segundo a posição da peça no ensaio de flexão, valores diferentes do módulo de elasticidade. Este trabalho tem como objetivo analisara influência da posição de peças roliças de madeira de Eucalyptus grandis na determinação do módulo de elasticidade na flexão. O ensaio de flexão utilizado é o de três pontos, sendo cada peça avaliada em duas posições distintas, definidas mediante o giro da seção transversal em torno do eixo. Os resultados encontrados indicam a necessidade do ensaio de flexão em, pelo menos, duas posições distintas da peça.
