Análise qualitativa da compatibilização de projetos através da aplicação da metodologia BIM. Estudo de caso: projeto escola SESI-AP
(UNIFAP - Universidade Federal do Amapá, 2023-08-23) SANTOS, Raigo Lima; SOUZA, Heldio José Carneiro; http://lattes.cnpq.br/8262388913887180; https://orcid.org/0009-0003-5229-8910
The production of projects, the construction of works and the development of all types of projects through BIM (Building Information Modeling) processes, provided great advances for civil construction and all the stages that are part of the life cycle of an enterprise. BIM has been technologically structured over the decades, mainly through the parameterization of its tools and, in the current situation, it has been replacing all the traditional processes of CAD projects and, with that, it has been bringing concrete and validated solutions to the old bottlenecks traditional processes, among which the compatibility of projects stands out. In Brazil, there is already a strong incentive to adopt BIM, through Laws, Decrees and Standards that have been produced with this objective. Among such incentives, Decree No. 10,306 of April 2, 2020 stands out, in which it places the compatibility stage as an integral part of the design processes, introduced in part b) of its Art. 4, in which the detection of physical and functional interference is referenced. It is evident that BIM has a wide field of applicability, however, the work in question will be restricted to qualitatively evaluating the project compatibility process through a case study of a project developed using the BIM methodology, in the year of 2022, by the Company Line Projetos e Construções, located in the municipality of Macapá, capital of the state of Amapá. The pondered project was labeled Sesi School - Ap, characterized as a two-story building, with 2490 m², with all systems developed, modeled and made compatible through Autodesk's Revit software in a workflow with BimCollab. In this design process, vertical coordination was applied, in the figure of the coordinator as the main intervenor, and horizontal coordination, in the figure of the collaborators. The main results achieved with this approach were assertiveness in the modeling process of each system involved; high productivity for project production; real-time integration of all developed models; synchronous and bidirectional communication between the actors involved; the expressive decrease of the incompatibilities between the projected systems; records of information, as well as decision-making and traceability of solutions adopted throughout the project.
Análises dos impactos financeiros da pós crise pandêmica de COVID-19 na rede de suprimentos de uma empresa de médio porte na cidade de Macapá/AP
(UNIFAP - Universidade Federal do Amapá, 2023) RIBEIRO, Rafael Cordeiro; NUNES, Regis Brito; https://lattes.cnpq.br/5252360529673878; https://orcid.org/0000-0003-3894-7139
Taking into account the instability of the national economy, especially those caused by the COVID-19 pandemic. In the construction sector, the accuracy of cost assessment in the supply chain of a project, as well as its frequent updates, is essential for the success of a venture, ensuring compliance with established values and providing maximum profitability. In this regard, this research aimed to analyze how the crisis resulting from COVID-19 influenced the prices of the main inputs in a medium-sized construction company in the city of Macapá, Amapá. Thus, a case study was conducted, where the collected data originate from archived and completed purchasing processes of a medium-sized construction company in the city of Macapá, Amapá. A significant variation was identified between SINAPI costs and the purchase price of the inputs used for the project's construction. Taking into consideration the pandemic scenario and the economic instability experienced in the country, this variation between SINAPI and the purchase price can be justified.
Análise dos processos de gerenciamento de manutenção predial na rede estadual de ensino do Amapá pela Secretaria de Estado da Educação

Schools, among public buildings, constitute an important portion of the country's built heritage. The majority of public schools are located in old buildings that require greater attention, as they end up exceeding the useful life of the project, or showing premature degradation. Services related to building maintenance directly influence the quality, comfort and safety that a building provides to its users. Furthermore, building maintenance activities are essential for the economic conservation of buildings. Taking into account the school infrastructure, it plays an important role in student learning, as an environment that does not provide comfort, functionality and safety limits the development of teaching and its potential, in addition to demotivating those who attend there, not only students, but also teachers, technicians and the community in general. In this sense, this research aimed to analyze the procedures adopted by the State Department of Education of Amapá in managing building maintenance in state schools, with the aim of understanding the current model, as well as identifying the main gaps and existing challenges. Thus, the research was conducted using a mixed approach, combining quantitative and qualitative methods, allowing a comprehensive and in depth understanding of the subject. The building maintenance management processes in the Amapá State Education Network face challenges that include the diversity of buildings, budgetary shortages, difficulties in prioritizing works, adaptations necessary to comply with accessibility and health surveillance standards, among others. Furthermore, the methodology used in tenders is often not suitable for the variable nature of maintenance, resulting in unforeseen costs and limitations in service capacity. To overcome these challenges and improve the system, it is essential to adopt a more flexible approach, considering the diversity of schools and their specific needs. The standardization of processes and procedures, together with the appropriate choice of methodology used in tenders for contracting building maintenance services, can contribute to the effectiveness, economy and quality of the services provided.
Aproveitamento da água da chuva para fins não potáveis: Estudo de caso aplicado a duas edificações padrões da UNIFAP

Cities are experiencing increasing difficulties to ensure the public supply of drinking water. Given the current scenario of population increase and the non-rational use of water resources in Macapá-AP, the present work was motivated to seek the technical and economic feasibility to propose a sustainable solution for the use of rainwater, in order to minimize problems related to water supply and stormwater management (urban drainage) in the current and future scenario at the Federal University of Amapá (UNIFAP) campus mark zero. This study evaluates the technical and economic feasibility of using rainwater for non-potable purposes as an alternative source of water supply in two standard buildings at UNIFAP. Initially, to analyze the technical feasibility, the catchment areas were surveyed, the rainfall data of the region was collected, the total and non-potable water demand was estimated. Subsequently, the computer program Netuno was used to determine the volume of the lower reservoir, which indicated an ideal volume of 20 m³ for the reservoir, for the upper reservoir the volume of 5m³ was previously adopted, whose together represented a potential saving of drinking water of 21.27%. For the assessment of economic viability, the cost of implementing the investment, labor costs, maintenance costs and the savings resulting from the use of drinking water before and after the installation of the system were considered. This was done by applying the local water tariff, and a balance of the period needed to recover the investment. The economic analysis showed that the estimated cost of implementing the system would be R$56,947.49, and compared to the annual savings of R$19,972.77, brought about by replacing 21.27% of drinking water with rainwater, results in an estimated payback period of 2 years, 10 months and 10 days. The advantages resulting from this system are not only financial, but also environmental and cultural. The reduction in the volume of precipitation, thanks to the stored portion, can mitigate the impact of precipitation capable of generating flooding on campus.

Since the civil construction sector represents a social and economic milestone, both in Brazil and worldwide, which seeks to meet community demands, whether housing, industrial, infrastructure, etc., its constant rise has required an increase in the technical standards employed, that is, the uninterrupted development of the processes of improvement and elaboration of materials, equipment and constructive techniques. Among these criteria is the adoption of inputs with greater mechanical resistance, durability and better surface finishes, as in the case of reinforced concrete that replaced the former use of stones (BAUER, 1999). Despite being a material that is best used on the construction site, reinforced concrete, as well as other civil construction materials, has limitations in terms of durability and performance that cause the appearance of structural pathologies over time. In this way, it appears that any and all buildings, however satisfactorily designed and executed, will present over the years some manifestation of structural deterioration and consequently some pathology of a structural nature. Faced with this situation, a new sector of technical development in civil engineering called structural reinforcement appears, which seeks to discuss analytical behavior and structural problems in a scientific and technical way. This new topic seeks to understand the origins, manifestation, mechanisms and systems of structural degradation (SOUZA; RIPPER, 2009). In this way, the present work seeks to present, in a succinct way, the causes and constructive techniques of structural reinforcement applied in a situation in a case study of reinforced concrete elements in centered compression (pillars), as well as the stages of analysis, development and elaboration of structural recovery projects.
