The research was applied at the Maestro Almir Garcez Assaí Music School (EMMAGA) in Bacabal-MA, aiming to address the growing need for sustainable solutions in civil construction and the potential of green coconut husk fiber, an abundant waste in Brazil, as a sound-absorbing material. Initially, the sound conditions of room D-01 at EMMAGA were assessed through measurements of sound pressure levels, according to NBR 10152:2020, and estimation of reverberation time, using the Norris Eyring formula with the Reverb software, identifying deficiencies that compromise acoustic comfort. Subsequently, the performance of the proposed intervention, which combines coconut panels and double wall gypsum board, was simulated again adopting the absorption coefficients of the fiber panels and absorbing elements for calculation purposes, eleven musicians seated with instruments. The simulation results demonstrated a significant reduction and balance in reverberation, validating the effectiveness of the proposed solution. It is concluded that this combination of materials represents a viable, sustainable, and high-performance alternative for sound optimization in educational environments. 2025-07-11T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/5842 Título: Manifestações patológicas na construção civil: revisão bibliográfica para identificação de problemas e estratégias para preservação Abstact: Assessing, diagnosing and preserving properties affected by pathologies are essential steps to prevent problems from becoming more serious, offering safety to users and ensuring the longevity of buildings. Maintaining the integrity of structures through efficient preventive maintenance ensures protection while also contributing to the sustainability and preservation of architectural heritage, avoiding waste and high costs in the future. The objective, therefore, was to investigate the influence of pathological manifestations in civil construction, aiming at the evaluation, diagnosis and preservation of properties. Methodologically, it was an exploratory and comparative bibliographic review based on qualitative research. As a result, it was found that conservation measures are not always easy and can entail high costs, especially in older buildings, where losses can be considerable. Therefore, a thorough assessment of the pathology, combined with appropriate planning of resources and techniques, is essential to ensure the effectiveness of repairs and the lasting maintenance of buildings. It was also concluded that defects identified in constructions require a thorough examination and efficient corrective actions to ensure the safety and longevity of buildings. Carrying out an appropriate diagnosis, along with well-planned and implemented corrective actions, can prevent the deterioration of structures and help create a safer urban environment. 2025-07-21T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/5841 Título: Manifestações patológicas de umidade em residências afetadas pelas enchentes do Rio Mearim: estudo de caso na cidade de Bacabal/MA Abstact: This final project focuses on pathological manifestations of moisture in homes affected by the Mearim River floods, focusing on homes located on Rua Santa Teresinha, in the municipality of Bcabal, Maranhão. The overall objective is to diagnose the pathological manifestations resulting from moisture in the affected homes, as well as describe and present these anomalies, evaluate the construction systems, and identify aspects related to safety, health, and habitability. The research was developed with the combination of two methods, descriptive and exploratory, through a qualitative approach, using bibliographic surveys, visual inspections and photographic records, carried out during the month of May 2024. Four residences that present similar construction characteristics were analyzed, composed of masonry walls, without a conventional structural system (beams and pillars), with painted and ceramic coverings and, in some cases, exposed subfloor. The main pathological manifestations identified were damp patches, mold, mildew, peeling mortar and paint, and hygroscopic cracks. The results indicate that, although no imminent risk of structural collapse was observed, the buildings are in unsanitary conditions, compromising the comfort, habitability, and health of residents, particularly due to the presence of significant internal humidity and insufficient ventilation.The conclusion is that moisture from floods significantly contributes to the degradation of building elements and the loss of residential performance, necessitating the adoption of corrective and preventive measures, although it is recognized that, in the context analyzed, families lack the resources to carry out these interventions. The study contributes technically to the field of Civil Engineering by understanding the pathological manifestations of moisture, and socially by highlighting the importance of public policies for technical assistance in social housing. 2025-07-11T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/5840 Título: Avaliação do gerenciamento de resíduos de construção civil e demolição gerados em canteiros de obras no município de Bacabal - MA Abstact: The construction industry plays a vital role in society's development, utilizing a variety of resources to achieve results. However, this scenario promotes the generation of waste that negatively impacts the environment and compromises the comprehensive development of sustainability in civil engineering. In this context, this study seeks to evaluate the management practices used on construction sites by identifying waste types, analyzing daily management practices, and recommending best practices. To this end, a structured questionnaire was administered to construction professionals to understand their perceptions of waste management on construction sites in the region, based on a literature review and a structured interview with the Municipal Department of the Environment. The results revealed that the lack of a sanitary landfill hindered the effective implementation of management measures. It also revealed that sorting is an effective method for management within the construction site, as it facilitates the identification of materials for possible reuse or recycling. Nevertheless, it was proven that the main measure is the reduction that can be incorporated into the project planning through the use of BIM technology. The study notes that the main waste materials discarded at construction sites are masonry, wood, concrete, plaster, and plastic. Therefore, the main obstacle to implementing management measures is the culture of improper disposal. Therefore, the main solution is environmental education. 2025-07-11T00:00:00Z
