Inspeção predial dentro dos prazos de garantia legal: edificações verticais de múltiplos pavimentos

Giovani Galvão dos Santos Ribeiro 29 September 2015 (has links)
As ações de Inspeção Predial em edificações verticais dentro do período de garantia legal são procedimentos essenciais dentro da Engenharia Diagnóstica. Fundamentados nestes procedimentos pode-se identificar precocemente danos que reduzem a vida útil dos subsistemas construtivos, bem como planejar e monitorar ações e planos de manutenções, proporcionando maior funcionalidade e segurança da edificação, garantindo a maximização dos prazos de garantia legais dos seus subsistemas construtivos. O objetivo deste trabalho é propor um roteiro para o processo de inspeção, permitindo que este seja utilizado por profissionais das diversas modalidades da Engenharia e Arquitetura, Peritos, etc., devidamente qualificados para a realização da inspeção predial, bem como Administradores de Condomínios, Sindicatos de Habitação, Síndicos, proporcionando assim uma padronização no processo de inspeção destas edificações, facilitando a identificação das não conformidades bem como a tempestividade da notificação destas ao construtor, através da elaboração de um roteiro com as etapas de inspeção de cada subsistema com seus respectivos prazos de manutenção. Este trabalho fornecerá subsídios para implantação de procedimentos que deverão se tornar rotina aos administradores das edificações recentemente construídas, minimizando as manifestações patológicas através do diagnóstico precoce, prolongando a vida útil dos subsistemas e gerando uma melhor relação de convivência entre condomínios e construtoras. / The Building Inspection actions in vertical buildings within the legal warranty period are essential procedures within the Diagnostic Engineering. Based on these procedures can identify early damage to reduce the service life of the building subsystems, as well as planning and monitoring actions and maintenance plans, providing greater functionality and security of the building, ensuring the maximization of the legal warranty periods of the constructive subsystems.The objective of this paper is to propose a roadmap for the inspection process, allowing it to be used by professionals from various forms of Engineering and Architecture, experts, etc., suitably qualified to carry out the building inspection and Condominium Managers, Unions Housing, Liquidators, thus providing standardization in these buildings inspection process, facilitating the identification of non-compliance as well as the timing of the notification of these to the constructor, by drawing up a road map with the inspection steps of each subsystem with their respective deadlines maintenance. This work will provide subsidies for the implementation of procedures to become routine for administrators of the buildings recently built, minimizing the pathological manifestations through early diagnosis, prolonging the useful life of the subsystem and generating a better relationship of coexistence between condominiums and builders.

Conception d'un outil cognitif d'assistance à la prise de vue pour la photogrammétrie terrestre

Bach, Matthieu 16 April 2018 (has links)
Les infrastructures canadiennes se faisant de plus en plus vieillissantes, il est primordial d'en effectuer une surveillance régulière afin de garantir la sécurité publique. L'inspection des infrastructures consiste à suivre les déformations tridimensionnelles d'une structure sur une période donnée. Les techniques de photogrammétrie à courte portée figurent parmi les solutions permettant d'élaborer des modélisations 3D précises de structure et d'en réaliser la surveillance. Malgré leurs nombreux avantages, elles impliquent un nombre important d'étapes dont la qualité de réalisation dépend de l'expertise de l'opérateur. Ce mémoire présente la solution ergonomique de photogrammétrie courte portée qui a été élaborée pour l'acquisition et la modélisation 3D d'objets complexes. Plus spécifiquement, les composants de cette solution visent à apporter une assistance à un utilisateur non expert en photogrammétrie lors de l'acquisition des prises de vue afin de lui permettre de respecter les tolérances relatives à la configuration d'acquisition qui garantiront que le modèle 3D élaboré répond aux spécifications de précision et de complétude attendues.

Aerial inspection of complex structures using multi-modal procedures and data processing a comprehensive solution for drone-based multi-modal inspection of industrial components

Nooralishahi, Parham 28 July 2023 (has links)
Thèse ou mémoire avec insertion d'articles / Les systèmes aériens autonomes (UAV/UAS), communément appelés drones, sont un sujet de plus en plus important dans les inspections par essais non-destructifs (END). Avec les avancées technologiques significatives des caméras thermiques, les méthodes d'inspection visuelle acquièrent continuellement de l'attention dans les inspections END. Les inspections dans les zones difficiles d'accès sont coûteuses, parfois impossibles en raison de la nature de la zone ou des dangers possibles pour les ressources humaines. L'inspection de spécimens complexes et de grande taille, notamment les des structures courbes, nécessite des relevés approfondis sous différents aspects, ce qui est presque impossible ou très coûteux avec des véhicules terrestres ou des ressources humaines. Ainsi, en raison de leur grande manœuvrabilité, les industries investissent davantage dans les drones pour surmonter les problèmes mentionnés et aider les inspecteurs à examiner les composants de manière approfondie. De plus, grâce à des développements récents, les UAVs peuvent également accéder à des zones éloignées ou difficiles d'accès et transporter de nombreuses charges utiles. Malgré les énormes avantages de l'utilisation des drones pour l'inspection, certains défis doivent être relevés. Ces dernières années, de nombreuses études se sont concentrées sur l'utilisation d'images thermiques/visibles pour inspecter différentes structures. Cependant, l'utilisation de données d'inspection multimodales par drone, y compris les données d'imagerie visible, thermique et de profondeur, pour fournir une compréhension approfondie de l'échantillon et de son environnement afin de produire une analyse plus précise, doit être étudiée en détail. Tout d'abord, cette étude aborde les défis communs des inspections par drone. La détection de l'effet de la réflexion thermique dans une inspection thermographique est le premier défi abordé dans cette étude. Ensuite, l'effet des mouvements constants et soudains d'un drone sur l'analyse des séquences d'images thermiques est étudié de manière approfondie. En outre, les résultats sont évalués à l'aide d'un scénario d'utilisation où le drone surveille un endroit fixe tout en restant en vol stationnaire. Par la suite, cette étude vise à développer une plateforme multi-sensorielle comprenant une structure de montage, des capteurs d'imagerie et un ordinateur embarqué. La solution logicielle intégrée à cette plate-forme fournit les fonctions requises d'acquisition, de transmission, de stockage et de traitement des données. De plus, cette étude se concentre sur le traitement de modalités multiples ou individuelles. Notamment, une méthode de segmentation par auto-apprentissage est proposée dans le contexte de la détection de défauts dans les images thermiques. Aussi, un algorithme de détection de fissures par drone est présenté pour analyser l'inspection visuelle des chaussées et des structures en béton. Ensuite, cette étude s'est concentrée sur le traitement des données multi-modales acquises par la plateforme multi-sensorielle présentée. En effet, l'utilisation d'images thermiques et visibles couplées pour améliorer la détection des anomalies est étudiée de manière approfondie. Plusieurs scénarios d'utilisation sont introduits présentant différentes approches pour améliorer l'efficacité de la détection. Ces derniers fournissent un aperçu de l'applicabilité des sous-études introduites. Pour chacun d'entre eux, de multiples expériences sont menées pour démontrer les applications des méthodes proposées dans des scénarios de cas réels. / Unmanned Aerial Vehicles/Systems (UAVs/UAS), commonly known as drones, is a rising topic in Non-Destructive Testing (NDT) inspections. With significant technological advancements in thermal cameras, visual inspection methods continuously gain much attention in non-destructive inspections. Inspections in remote or hard-to-access areas are costly and sometimes impossible due to the area's nature or the possible dangers facing human resources. Inspection of complex and large specimens, especially with curvaceous structures, requires extensive surveys from different aspects, which is nearly impossible or very costly using ground vehicles or human resources. Thus, industries are investing more in drones to overcome mentioned problems as they have high flexibility of maneuver, which can assist inspectors in examining the components thoroughly. They can also access remote or hard-to-access areas and carry many payloads thanks to recent developments. Despite the enormous benefits of using drones for inspection, some challenges need to be addressed. In recent years, many studies focused on using thermal/visible images to inspect different structures. However, using multi-modal data, including visible, thermal, and depth imagery data, provides an extensive understanding of the specimen and surrounding environment in case of drone-enabled inspections and produces a more accurate analysis that needs to be thoroughly studied. Firstly, this study addresses the common challenges in drone-based inspections in the scope of this research. Detecting the effect of thermal reflection in a thermographic inspection is the first challenge addressed in this study. Later, the effect of a drone's constant and sudden motions on analyzing thermal image sequences is investigated comprehensively. Also, the results are evaluated using a use-case scenario where the drone monitors a fixed location while hovering. Also, the next part of this study aims to develop a multi-sensory platform, including a mounting structure, imagery sensors, and an onboard computer. The software solution embedded in this platform provides the required data acquisition, transmission, storage, and processing features. Later, this study focuses on the processing of multiple or individual modalities. Firstly, a self-training segmentation method is proposed in the context of defect detection in thermal images. Also, a drone-enabled crack detection algorithm is presented for analyzing the visual inspection of pavement and concrete structures. Next, this study focused on processing multi-modal data acquired by the presented multi-sensory platform. Firstly, using coupled thermal and visible images to enhance abnormality detection is investigated thoroughly. Several use-case scenarios are introduced, presenting different approaches to enhance the detection's efficiency. In order to provide insight into the applicability of the introduced sub-studies. For each of them, multiple experiments are conducted demonstrating the applications of the proposed methods in real-case scenarios.

Amélioration de l'inspection thermique des bâtiments grâce à l'analyse de texture

Hesam, Setayesh 04 April 2024 (has links)
Titre de l'écran-titre (visionné le 25 mars 2024) / Ce mémoire présente une nouvelle approche automatisée pour détecter les fuites thermiques lors des inspections de bâtiments. Nous exposons un cadre intégrant de manière cohérente l'enregistrement automatique d'images, la segmentation d'images et la fusion des résultats segmentés issus à la fois d'images visibles et thermiques. Notre recherche compare rigoureusement les techniques d'enregistrement manuel et automatique d'images, démontrant que la méthode automatique, exploitant l'algorithme de la Transformée de Caractéristiques Invariantes à l'Échelle (SIFT), surpasse l'approche manuelle en termes d'efficacité, de précision et de reproductibilité. La segmentation des images utilise une approche supervisée pour les images visibles, en adoptant spécifiquement une architecture UNET++ et Resnet 152, tandis que les images thermiques sont segmentées en utilisant la méthode non supervisée de Kanezaki. Les résultats segmentés de ces divers types d'images sont ultérieurement fusionnés, fournissant une représentation exhaustive et précise des fuites thermiques à travers différentes parties du bâtiment. La qualité de la fusion dépend de la précision des étapes antérieures, soulignant l'importance de chaque étape dans ce système intégré. Ce travail démontre l'efficacité de notre nouvelle approche dans le domaine de l'inspection automatisée des bâtiments et ouvre la voie à de futures explorations et innovations dans ce domaine. Le mémoire est structuré en quatre chapitres, débutant par une revue exhaustive de la littérature, suivie de la méthodologie proposée, des résultats et des discussions, et se conclut par les orientations pour les travaux futurs.

Avaliação de estruturas de edifícios em concreto armado com vistas à reabilitação / Evaluation of building structures in concrete with a view to rehabilitation

Jackline de Assis Lopes Santos Oliveira 27 March 2008 (has links)
Com o crescente número de ocorrências patológicas encontradas nas estruturas de concreto armado, conforme levantamento de danos realizado por Dal Molin, 1988; Andrade, 1997, cresce também a demanda por serviços de inspeção e manutenção nos condomínios residenciais no Estado de Pernambuco e em todo o País. Entretanto, é possível observar que a prática de inspeções periódicas ainda não faz parte da cultura de uma determinada faixa da população, que não possui meios econômicos, e conhecimento da importância da manutenção para garantir a integridade da estrutura. Estas inspeções visam detectar danos à estrutura em tempo hábil a minorar os custos de reparo, aplicando assim uma manutenção preventiva como forma de garantir a vida útil estimada em projeto para a edificação. Foi utilizado neste trabalho um roteiro de inspeção com utilização de ensaios e metodologia de quantificação de danos, para verificar o estado de degradação de três edifícios residenciais, com mais de vinte anos de construídos e próximos à orla marítima onde a agressividade ambiental é forte. A deterioração encontrada em cada um dos edifícios foi devido à intervenção inadequada realizada em cada prédio. A última intervenção realizada na Edificação A, foi corretiva executada por mão de obra não qualificada orientada pelo próprio condomínio, que não tem conhecimento técnico na área de engenharia civil. Na edificação B, a situação é semelhante, agravada pela opinião de alguns condôminos de que não há necessidade desta rotina, mesmo a estrutura estando em estado crítico, conforme confirmado com a aplicação da metodologia ora proposta. E para a edificação C, na ocasião da pesquisa, existia uma empresa de engenharia civil executando os serviços de manutenção, porém isto se deve, de forma pontual, a gestão atual do condomínio / With the growing number of serious problems found in the reinforced concrete structures, according to the research on damage done by Dal Molin in 1998 and Andrade 1997, there has been a growing demand for inspections and the maintenance of residential buildings both in Pernambuco and country as a whole. However, it is possible to observe that the practice of periodical inspections is still not part of the culture of a specific section of the population, who don`t have the financial means nor a knowledge of the importance of maintenance as a guarantor of the building`s safety. These inspections aim to detect structural faults in time to minimize repair costs. Preventative maintenance is meant to guarantee the useful life of the building. In this study, there was an inspection schedule using tests and a methodology to measure damage, to check the state of direpair of three residential buildings, all more than 20 years old, all on the coast where the environmental effects are strong. The deterioration found in each of these buildings was due to inadequate preventative measures. The last action taken in Building A was undertaken by unqualified labourers directed by the condominium with no technical knowledge in the area of the civil engineering. In Building B, the situation is similar, worsened by the opinion of several residents who think that there in no need for this kind of inspection. And this even though the building is in a critical state according to the research done. As for Building C, at the time of our research, there was a civil engineering firm performing maintenance services, though this is due to last minute action taken by the present management of the building
