We can consider masonry with one of the main foundation of the construction system for the development of a project, vertical sealing masonry is a subsystem that directly interferes in the construction processes that comes next as electrical and communication installations, hydraulic installations, coating and finishes in general, waterproofing, acoustic insulation and frames, we come to the conclusion of the importance not only economic subsystem , but also of its great importance in relation to the deadlines for the execution of the other services of the work. Remembering that a construction system is a set of subsystems and components that relate to each other. And the relationship between these components and the subsystems respects a mode of organization. The objective of this study is to evaluate the technicaleconomic feasibility of a construction process of sealing masonry with vertical holes, considering a system with agility, that is, a system that decreases execution time, focusing directly on the production of labor, in addition to low mortar consumption. Based on the productivity and quality history of the conventional system with block with holes horizontally well with its needs and characteristics, we will analyze the positive and negative points of both. The rationalized masonry system is based on productivity, quality and flexibility, providing clean, fast and safe works. In general, I will analyze the cost of benefit that this system focuses on civil construction, that is, an economic analysis of a sealing masonry model will be presented, and thus taking into account the productivity gain, and respect for the environment, because through the study we can verify the reduction of waste generated by masonry, such as waste from brick breaks (in the settlement and conventional and precarious act of instilling the facilities. This system has feasibility for high standard enterprise with reinforced concrete structure, because it is allowed modification, because the block has the sealing function, and to resist only the weight of the masonry of which it is part, and in addition to the agility at the time of electrical and hydraulic installations, because it is born right after the marking of the first spun.
Avaliação do comportamento mecânico da mistura de um solo Laterítico com cimento Portland

The present study proposes to evaluate in a comparative way the influence of the addition of Portland Cement on the physical and mechanical properties of a soil sample collected in the metropolitan region of Manaus-AM. For this purpose, consistency and granulometry limits have been tested for characterisation; compaction, to obtain optimal humidity and maximum dry apparent specific mass, and finally, test for Índice de Suporte Califórnia – ISC and expansion. The comparative analysis was done by interpreting the results obtained with the soil in the natural condition (SN) in front of samples with addition of 3% Portland cement (SN + 3% CP). The results point to little influence on the physical parameters, however a 563% improvement in ISC.
Gestão de resíduos sólidos urbanos em Manaus – análise das modalidades: coleta domiciliar e coleta seletiva
(2023-03-12) Silva, Lais de Souza
The urban solid waste (USW) management has been earn prominence around the world, because an inadequate management cause a series of negative impacts on the human Life. The impacts go since atmospheric pollution until visual pollution and even same the health population. The article is about management solid waste USW in the modality home and selective collection one of being more practiced on the city but behind bad consequences for the population and the other is on the process implementation with focus on reducing impacts in the environment. The chalegend of USW management is ponder the exaggerated generation and ensure environment a good final disposal of wastes. The objective of this study is to show how could be done the USW management in the modality home collection and selective collection. The methodology used to achieve established objectives was bibliographic search exploratory documentary as qualitative nature cause it aim valuable results that add knowlegde to the society such informations was taken of publications made in the databases, most used for research in Brazil, and in the world and in the government web sites. The study points out as a result that we have a idealized management in the theory way but in the practice form there are one deficiency in your implementation.

Reconstrução de um projeto comercial com a utilização da tecnologia scanner para BIM
(2023-03-31) Oliveira, Wenderson Igor de Almeida; Silva, Felipe Wilson Leão da; Barros, Laerte Melo
Modeling aims to make built environments easier to understand, define and quantify materials, visualize, and simulate physical spaces. Currently, building information models (BIM) have been widely used in the creation phase of new constructions, but the use of BIM becomes a challenging process when it needs to be applied in buildings that were built before the technology existed. And today, engineering and construction needs more efficient information models for the reconstruction of 3D projects of old buildings and the architectural heritage of large cities, to facilitate decisionmaking in renovations and new adaptations. The traditional process to create or update the 3D modeling of a building built before BIM is a time-consuming and laborious procedure. Laser scanning technology from point clouds with the integration of a global positioning system, for refinement and adjustment of the external and internal environments of the building help to reduce errors. This article proposes a procedure capable of integrating images and accurate information from a mobile LiDAR scanner by point clouds, a positioning system, and finally, a reconstruction BIM model. The results showed that the procedures improved the quality of the reconstruction in terms of completeness, precision, and speed in modeling.
Renaturalização de cursos d’água em Manaus/AM
(2020-05-12) Chaves, Adelina Cristina Augusto; Carvalho, Iraúna Maiconã
The Manaus City has important urban watersheds that have high levels of pollution, occupation of the margins, reduction of natural drainage and accumulation of solid waste. Such areas need alternatives that enable the landscape to change positively, improving the quality of these areas, mobility and leisure in the community. This work identifies and maps the main streams and water courses in the Manaus’s watersheds and proposes alternatives for the naturalization of the streams' areas, aiming to guarantee the return of the water courses in their fullness. It uses georeferenced hydrological maps of the Manaus’s watersheds, research by public agencies and a bibliographic review by local scientists, who investigate the recovery of riverbeds. Hence, it delimits the watersheds and proposes alternatives for the renaturalization of watercourses. In this way, it aims to contribute to the discussion regarding environmental sustainability and contribute to raising awareness of the need to implement actions with socio-environmental responsibility.
