Resumo
The main objective of this research is to proceed to the rising of the indexes, to identify the pathologies and to characterize the constructions that presented occurrences of pathological manifestations in foundations and structures in the
constructions executed in the State of Goiás, with age of up to ten years. The researches was classified as documental, considering that, to make possible the accomplishment of the same, the files of Regional Council of Engineering, Architecture and Agronomy of Goiás were analyzed -Crea/GO, with a total sample of 545 reports. It was observed that most of the processes are concerning the last seven years. This Organ was chosen by the fact that all of the technical documents are elaborated by professionals, and, mainly, for
Official Organ to be considered. The Method of the Incidence was adopted as methodology recommended for this study observing that in the reports and decisions, elaborated by Crea-GO doesn't be in the number of occurrences of a same pathology and yes only the incidence of the same. The main conclusions of this research were: the main pathological manifestation was found in the foundations repression with a rate of 37.50% followed by collapse with a rate of 22.50%, both in relation to all the pathologies found in the foundation stage, the main pathological manifestation found in stage structure were the cracks with an index of 32.14% compared to all the pathologies found in stage design, regardless of the number executed and the second structural pathological
manifestation found in step structure was the structural deformation with an index 19.84% as compared to all the pathologies found in stage design, regardless of the structural piece performed, the building of single-family residential use were the same who had diseases with a rate of 47.50%,
followed by residential conference with 35 %, 77.50% of the buildings showed that diseases were carried out by private tutors and, for the buildings surveyed 40% had impairment evaluation of use of buildings facing the diseases occurred
in moderate severity, and the rate for high severity was 5%. The disease occurred in low gravity, 45%, most pathological manifestations of both the foundation and structure, occurred in the first year of age of the building. 52.17% in the foundation and concrete structure in 40% of the buildings
surveyed, 35% caused damage to neighboring buildings, and 53.49% of this damage occurred within the first year after completion of the work, and the buildings with an area of 5001 m² to 10,000 m² which caused the highest
percentage of damage, and the recklessness and incompetence were more technical errors committed by professionals with rates of 32.50% each, followed by neglect of index 22.50 %.
