Diagnóstico de patologias e proposta do projecto de reabilitação de um edifício de 3 andares na Cidade de Maputo

Abstract

This work addresses the study of the existing pathologies in a building located in the City of Maputo, with the aim of identifying, diagnosing, and proposing appropriate solutions for its rehabilitation. The methodology adopted included visual inspection, photographic recording, and mapping of the pathologies. In parallel, a comprehensive literature review was carried out, focusing on standards, technical recommendations, and specialized literature. Based on this information, the pathologies were classified and diagnosed, grouping them by type, causes, consequences, and possible solutions. Finally, intervention proposals were defined within the scope of the executive project, including technical specifications, procedures, and a bill of quantities. The results show that the most recurrent pathologies are cracks and stains associated with humidity, followed by degradation of coatings and localized detachments. The severity analysis revealed that most anomalies are minor, although there is a significant set of medium-level pathologies and a small but relevant proportion of severe ones. This distribution made it possible to establish intervention priorities and guide the design of the proposed solutions. It is concluded that the building presents clear signs of deterioration, mainly related to infiltrations, hygrothermal variations, maintenance shortcomings, and ageing of materials. The interventions proposed in the executive project constitute essential measures to restore performance and extend the service life of the construction.
