The aim of this present research is to investigate about aplication of the supply chain management in Civil Construction, through perception of brasilian building companies directors. Research purpose includes potential benefits and main dificults analysis in supply chain management, beyond to identify decision criterions for suppliers and sales chain (commission agent and real state agency) choice and reduction, to facilility management in companies. The methodology used in this work considers the application of a questionnaire with scales of the type Likert being constituted of variables that compose the aspects of evaluation and of behaviors, beyond questions to identify the market profile of the respondents. For analysis statistics is used the descriptive, clusters and variance, ANOVA, analysis last two to verify the connections between variables. The results show more perception as for long terms contracts with suppliers for purchase of materials and services being decisive for companies nowadays (40%) than as for exclusive contracts with commission agents (30%). There is a positive appraisal about viability of hipotetic situations showed, but more caution as for disposition to apply them too. Another results aim for biggers dificults in management of chain links formed by commission agents and real state agencies, than chain links formed by anothers suppliers of materials and services. The companies for study were chosen among to those with ISO 9000 certificate until november 2001, considering that these companies have the best management systems, probably

Este trabalho relata a pesquisa desenvolvida sobre a prática pedagógica de educação em ciências vivida e construída junto com educadores atuantes no ensino fundamental da Escola São José de uma comunidade ribeirinha, situada na Ilha Grande no município de Belém. Com a intenção de conhecer para compreender a prática pedagógica desses educadores ribeirinhos, buscando um elo entre a educação em ciências e as práticas sócio-culturais cotidianas daquela comunidade tendo em vista possíveis interações e estudos de temas sociais no ensino de ciências. Partiu-se de inquietações, tais como: como se configuram as práticas pedagógicas que os professores da Escola São José, vêm construindo, com respeito às questões sócio-culturais da comunidade da Ilha Grande, na produção do conhecimento escolar na educação em ciências de crianças ribeirinhas? A opção metodológica de investigação foi a pesquisa participante, ao buscar-se um caminho investigativo que não fosse solitário, mas sim, em companhia dos participantes no esforço de juntos aprender, partilhar, criar num processo dialógico e humanizante. Destaca-se a abordagem narrativa como forma de expressar a compreensão e possíveis respostas aos questionamentos diante das vivências, aprendizagens e escuta das vozes advindas do processo de pesquisa. Foram realizadas entrevistas semi-estruturadas, e encontros pedagógicos para estudo e planejamento com os professores na proposição de atividades sobre temas socialmente significativos, na área da educação em ciências. Dos momentos de entrevistas, construíram-se dados que possibilitaram a emergência de temas em relação à escola e ao ensino de ciências, concepções e práticas daqueles educadores ribeirinhos, tais como: o que pensam os professores a respeito do ensino de ciências, o lugar das questões sócioculturais neste ensino, e a afetividade como peculiaridade naquela escola ribeirinha. Abordou-se a temática: O açaizeiro – palmeira fonte de vida. Os dados e o relato construídos a partir desta abordagem foram organizados em forma de eixos temáticos, os quais se constituem recortes das experiências vividas nos encontros pedagógicos, nos quais se destacam relações da prática pedagógica dos educadores ribeirinhos com as questões sócio-culturais da comunidade da Ilha Grande. Práticas pedagógicas já existentes, outras que foram sendo construídas no caminhar de uma proposta/aposta de educação em ciências. As análises possibilitaram conhecer e compreender as práticas pedagógicas em três dimensões: Práticas aproximadoras; Práticas conciliadoras e Práticas construtoras. De modo que na interação com os sujeitos proporcionaram emergir (re) conciliações, desvelamentos, assumir inacabamentos e perceber-se em transição ao ensinar ciências, tendo como ponto de partida uma temática sócio-cultural daquela comunidade.

This work presents a fast, easy, standardized and planned method to build family homes in order to collaborate with the decline of housing deficit and, at the same time, meet families who wish to invest in building their own houses, once that our country is experiencing an economical prosperity . This method has been widely used nowadays because it is being deployed in large-scale and in a standardized pattern, reducing decreasing significantly the construction time. The concrete wall, shaped in loco depends on unique processes. For this reason, a well trained staff is required so the constructive process can be executed in a fast pace, showing better results than other construction methods. This project will address all the materials used to build the molded concrete walls in loco, their sequence assembly, application, types, characteristics and performances. At the end, a way used by building companies of locating the concrete will also be given. Although there is no specific Brazilian norm for this type of construction, a study on this topic will soon be released. Therefore, the studies for the execution of this project were based on Brazilian standards prevailing at the time, construction magazines and books that are based on building methods considered more common

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

On the grounds of the great advances achieved over recent years, the process HF/ERW (High-Frequency/Electric Resistance Welding)welded pipe have played an active role in the oil and gas industry for deep water applications, at high and extremely low temperatures, under high pressure and in highly corrosive environments, gradually replacing manufactured pipes by other processes. However, studies have shown that defects in the welded joints are a the leading causes of pipelines failures, which has required the determination of toughness values in this region, in compliance with the strict recommendations of the codes and standards with manufacturers and construction companies, on the oil and gas sector. As part of the validation process required toughness values, this research project focuses on a microstructural analysis in HF / ERW tubes microalloyed, steel grade API 5CT P110, designed to explore oil and gas in deep waters, the subject of strategic relevance to the country because of the recent discoveries in the Santos mega fields: Tupi and Libra (pre-salt). In this scientific work will be presented and discussed the results of mechanical tensile and Charpy, a few CTOD tests curves (showing the trend of toughness values to be obtained), and the microstructures of the base material obtained by optical microscopy, with special emphasis on the formation of nonmetallic inclusions in the welded joint

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

This paper has it is hypotesis on the government program “My Home, My Life” and the assumption that it is a public politic attached to the market logic of financialization of the housing. It is understood that this program encourage capital for the main constructors and incorporated of brazilian heritage elite. It also served as well to promote more rentability to international capital and intensified the sociospacial segregration process as real state speculation has been potencialized. This work aims to present and discuss the program contradictions that have been sustained on the speech of wide subsidy offer and habitance construcution for low income workers - month income until three minimum salaries. Documents have shown that in the first phase of the program, habitance construction for this sector of population corresponded only to 5,5% of total habitation deficit. Businessmen on residance civil construction and public politic representatives have confirmed that the program interests are linked to financial market logic.The real benefits are not for low income workers, but for real state agents through extraordinaty profits of land and the so called new medium workers class(worker class C).We will search for embasement on the country history through the different governments and housing policies, in value theory and the concept of land income to understand the financialization process of the housing. We will also analyse oficial documents and the agents speech involved in real state market to show program contradictions and whose the real benefts are for
