Proposta de Roteiro Metodológico para Inspeção Predial Preventiva Baseada na ABNT NBR 16747:2020

Abstract

Building inspection is an important tool for assessing the safety, functionality, conservation, and durability of buildings, contributing to the early identification of irregularities and to the planning of maintenance interventions. This study presents a methodological proposal to support preventive building inspection, based on the guidelines of ABNT NBR 16747 (2020) and the principles of Building Diagnostics Engineering. The research is based on the observation that, although technical standards and regulations related to building inspection exist, there is still limited standardization of inspection procedures, which may lead to differences in data collection, documentation, and interpretation. The adopted methodology consisted of a literature review, analysis of technical standards, and examination of tools used in building inspections, aiming to develop a practical and systematic inspection methodology. As a result, a technical inspection guide, an operational checklist for field inspections, an evaluation and classification checklist for identified irregularities, and flowcharts to support irregularity assessment and intervention priority definition were developed. The proposal also incorporates the classification of irregularities according to their nature and origin, including the category of natural anomalies, as well as the application of the GUT Matrix as a complementary tool for prioritizing corrective actions. It is concluded that the proposed methodology provides instruments capable of supporting the organization of inspection stages, contributing to a more systematic and standardized inspection process. Future studies are recommended to apply the methodology to real buildings to evaluate their effectiveness and identify opportunities for improvement.
