Num contexto em que construções antigas são alvo de intervenções profundas como reabilitações, há interesse em otimizar as soluções aplicadas para que sejam duráveis e economicamente rentáveis. Todos os elementos construtivos apresentam uma vida útil, que corresponde ao período de tempo em que estes servem as funções para que são projetados (fase de serviço) e onde devem ser aplicadas operações aos elementos que cumpram o objetivo de prolongar essa mesma vida útil. Há, portanto, a necessidade de implementar estratégias de intervenção que otimizem a vida útil de um edifício, após uma ação de reabilitação. Revela-se interessante pelo panorama de construção em Portugal, que apresenta muitas construções antigas e degradadas que aliando a reabilitação a operações de manutenção, se obteria um cenário próspero e economicamente sustentável. Neste sentido, a manutenção ganha uma dimensão importante na fase de exploração de um edifício. Se estiverem sistematizadas, num plano, todas as operações a realizar e as suas periodicidades, consegue-se a otimização desejada com custos controlados, que é a grande vantagem do processo, pois permite obter a melhor solução de custos associados à utilização dos edifícios. O presente relatório de estágio teve como objetivo o estudo da vida útil dos elementos fonte manutenção de um edifício reabilitado, recorrendo ao Método Fatorial e foi proposto um Plano de Inspeção e Manutenção (PIME) a ser implementado pela empresa que acolheu o estágio curricular de que trata este relatório, onde foram reunidas todas as operações consideradas relevantes para o bom desempenho dos elementos construtivos e respetivas periodicidades, recorrendo a pesquisa do estado da arte para a sua elaboração. Foi possível avaliar a durabilidade dos elementos construtivos, com base numa série de fatores, adaptados ao caso de estudo, que condicionam as suas vidas úteis, chegando aos valores das vidas úteis estimadas desses elementos. O Plano de Inspeção e Manutenção foi elaborado na medida de servir como base de apoio para ser adaptado às necessidades do edifício. Por fim, foi apresentado um estudo comparativo de custos associados às ações de manutenção, onde se verificou uma clara vantagem no controlo e avaliação dos custos, para se proceder à escolha da melhor solução.
In a context where old buildings are the target of profound interventions such as rehabilitations, there is an interest in optimizing the solutions that are applied so that they are durable and cost-effective. All building elements have a service life, which corresponds to the period of time when they serve the functions for which they are designed (service phase) and where operations must be applied to the elements that achieve the goal of prolonging this same service life. There is, therefore, the need to implement intervention strategies that optimize the service life of a building, after a rehabilitation action. It is interesting to consider the construction panorama in Portugal, which presents many old and deteriorated buildings, that by combining rehabilitation with maintenance operations, a prosperous and economically sustainable scenario would be obtained. In this sense, maintenance takes on an important dimension in the operational phase of a building. If all the operations to be performed and their periodicities are systematized in a plan, the desired optimization with controlled costs is achieved, which is the great advantage of the process, since it allows obtaining the best solution for costs associated with the use of buildings. The present report aimed to study the life cycle of the elements that will be source of maintenance actions of a rehabilitated building, using the Factorial Method. A Plan of Inspection and Maintenance was proposed to be implemented by the company that hosted the curricular internship that this report concerns, where all the operations considered relevant for the good performance of the constructive elements and their respective periodicities were gathered, using the state of the art research for its elaboration. It was possible to evaluate the durability of the construction elements, based on a series of factors, adapted to the case of study, that condition their service lives, reaching the values of the estimated service lives of these elements. An Inspection and Maintenance Plan was elaborated to serve as a support basis to be adapted to the needs of the building. Finally, a comparative study of costs associated to maintenance actions was presented, where it was verified a clear advantage in the control and evaluation of costs, to proceed to the choice of the best solution.
