This study aimed to attend the importance of holding management programs involving the waste of construction and demolition at the University by the resulting environmental, economic and social benefits, and analysis of the main stages of Waste Management of Construction and Demolition, whose based on the National Solid Waste Policy, as well as verification of the importance of implementing these steps in the design of works, assisting in future studies of this type of waste and the problems accompanying the University

Proposta de adequação à construção sustentável: tecnologias e alternativas para instituições de ensino

Due to the huge impact negative on the environmental caused by the civil construction, the university plays a majorital role in the proposal of studies and projects that aim the sustainable building. Nowadays, it has been noted the great demand for projects which contain a systemic focus in the tripod of the sustainable development, that is to say, more and more the consumers are demanding that the final result of a project contemplate the social, economic and environmental areas. According to the National Industry Confederation (CNI) and the Brazilian Chamber of the Industry and the Construction (CBIS), the goal for 2020 is that the constructions have an environmental performance 20% higher in comparison to the actual one, starting with an index defined by many indicators, such as: water consumption, energy, residues generation and social-environmental performance of the bought products. In this case, the theme of the project comes around the adequation of scholar institutions to the sustainable construction through simple changes of tecnologies and habits aiming the growth of the environmental eficiency of the enterprise and, consequently, the improve of sustainable practices inside the institution. Once the change is proposed, it will be furnished datas liable of reproduction for the adequation of others scholar institutions, according to it's necessity or interest. After the realization of the studies, it was possible to notice that the environmental performance of a scholar institution can be improved through the implantation of tecnologies of fast return in the investment, such as: flow reducers, rain water reuse system, green roof, retrofit of lamps and execution of a photovoltaic system. Besides the fast return of investment, the monthly economy of the applied tecnologies combined can reach 75% when compared to the actual spending with water and electric energy

Estudo sobre o uso de agregados reciclados na composição de concretos e argamassas

Two of the major problems caused by construction activity are the production of construction and demolition waste (CDW) and the exploitation of mineral resources, causing big impacts on the environment. Therefore, the recycling has been shown as an alternative to mitigate the harmful effects of waste on the urban environment and prevent the exploitation of new raw materials. This course work aims to study the behavior of recycled aggregates from Vale do Paraíba in concrete and mortar. Initially, it presents the definitions of recycled aggregates according to CONAMA Resolution No. 307/2002, the aggregate settings for concrete and mortar (such as the grain size, its origin and density, and the characterization parameters according to ABNT), and the definition of ACI method of concrete mix design. Afterwards, it presents the characterization of materials separated by assays. After that, it shows the theoretical concrete proportioning applying the ACI method and experimental concrete proportioning. Then, the analysis of results is performed to finally conclude that the materials provided can't be used to replace natural aggregates because they cannot have the same performance. With the studies, it could be observed that the recycled aggregate presents a great complexity and diversity in origin, therefore the form how the material should be handled requires great care

Aproveitamento da água de chuva para fins não potáveis para um condomínio sustentável: um estudo de caso

The End of Course Work this aims, the hydrological cycle of water on our planet, and explain about its importance in the lives of living beings, finally, carry out a detailed analysis regarding the financial feasibility of implementing a system Shauer sustainable in the condominium, the first being the pickup of river water, which will use a reservoir for capitation and filtering, a reservoir for water storage filtered and pumps that will redirects it to outside faucets and toilets use in residences

Proposta de captação de água de chuva de para fins não potáveis em projetos residenciais

Water is an economic, strategic and social valuable resource of the utmost importance to society. This renewable natural resource is increasingly scarce with the growing of populations, industries and agriculture, in addition to the pollution surface and underground water and the waste have aggravated this situation. Investments in the sector of water resources so that this resource meets in quantity and quality the demand from its multiple uses, represent a significant portion of national and regional budgets. Therefore, the use of alternative sources of water capture can reduce the pressure on conventional public water supply systems. In this work was designed and executed a rain water collection system to a residence in the city of Barueri (SP), which can be applied to other residences. In this system, the rooftop of the residence was used as the waterproof and capture area. The gutter and the PVC conductors were used for driving the water to two connected reservoirs. The stored water was designed to address activities that are not potable, such as washing clothes and external areas and garden irrigation. The system showed economic viability, with 34-month return of investment time, wherein after that period, in addition to environmental and social benefits derived from the implementation of the project, the economy made with the payment of public supply rates should be considered. This rainwater capture system is inexpensive and uses materials available in the market. Therefore, its application to a greater number of households should be encouraged as a measure of sustainable water management

Da coordenação modular à construção modular: estudos de caso

The presented work aimed to present the Modular Construction scenario, relating it to the fundamentals assumptions on the Modular Coordination Theory. The presentation of this theory, its historical development, its scope and tools, were conceived to further, show how the applicability on the conceptual and design phases is done. Also, studies cases are shown, in order to illustrate didactically how this process occurs. Basing on these studies, considerations are made about the use of modulation in projects in Brazil, at the expense of what happens on the international scenario, to highlight the importance of Modular Coordination for raising the standards of construction quality and rationality in the country

Avaliação da rigidez torcional do chassi de um protótipo Baja SAE através do método de elementos finitos e de ensaio experimental

The torsional stiffness of chassis is one of the most important properties of a vehicle's structure and therefore its measurement is important. For the first time, the torsional stiffness was considered on the design of a prototype Baja SAE of the team from UNESP - FEG, Equipe Piratas do Vale Bardahl. According to the team's opinion, the increase of stiffness on this prototype, called MB1114, made possible a great improvement in its performance during competitions. In this work, the experimental evaluation of the torsional stiffness from this prototype is performed, detailing the analysis of results, as well as, the hysteresis' effect, least-squares regression and uncertainty analysis. It also shows that it is possible to measure the torsional stiffness of chassis with a low experimental uncertainty without expending many resources. The test rig costed R$ 32,50 due the reuse of materials and the use of instrumentation already available on campus. Furthermore, it is simple to produce and can be easily stocked. Those features are important for Baja and Formula SAE teams. Lastly, the measured value is used to validate the finite element analysis performed by the team during this prototype's design, because similar studies will be performed for the new cars. After investigating the finite element analysis, one result 13,5% higher than the measured value was reached. This difference is believed to be occurred due the imperfections of the finite element model, in other words, for not been possible to simulate every phenomena present on the real model

Avaliação do software Autodesk Revit 2016 para quantificação por meio da modelagem da informação da construção

The building budgeting quickly and accurately is a challenge faced by the companies in the sector. The cost estimation process is performed from the quantity takeoff and this process of quantification, historically, through the analysis of the project, scope of work and project information contained in 2D design, text files and spreadsheets. This method, in many cases, present itself flawed, influencing the making management decisions, once it is closely coupled to time and cost management. In this scenario, this work intends to make a critical analysis of conventional process of quantity takeoff, from the quantification through 2D designs, and with the use of the software Autodesk Revit 2016, which uses the concepts of building information modeling for automated quantity takeoff of 3D model construction. It is noted that the 3D modeling process should be aligned with the goals of budgeting. The use of BIM technology programs provides several benefits compared to traditional quantity takeoff process, representing gains in productivity, transparency and assertiveness
