Este relatório resultou do estágio curricular colaborativo entre o Instituto Superior de Engenharia do
Porto e a empresa VN2R, tendo como objetivo principal a análise de metodologias para integração de
informação em modelos BIM para a verificação da segurança contra incêndios, com foco na
compartimentação corta-fogo.
Para atingir o objetivo mencionado, foi necessário, inicialmente, estudar o enquadramento
regulamentar português de segurança contra incêndios, nomeadamente o Lei n.º 123/2019 e a Portaria
n.º 135/2020. Foram analisados os critérios de classificação de utilizações-tipo, categorias de risco, locais
de risco e as áreas máximas de compartimentação corta-fogo, destacando-se as variáveis críticas
necessárias à verificação regulamentar.
O caso de estudo consistiu num edifício habitacional de dois pisos, incluindo divisões residenciais e
garagem integrada. Através deste modelo BIM e com recurso ao Autodesk Revit, foi possível avaliar
quatro metodologias distintas para representação de compartimentos corta-fogo: Room Tool, Spaces &
Zones, Area Tool e extensões externas.
Numa fase posterior, desenvolveram-se scripts automáticos em Dynamo através de quatro iterações. A
integração do processo com o formato IFC também foi explorada, utilizando propriedades como
IfcZone para agrupamento de compartimentos e propriedades personalizadas para armazenar dados de
segurança contra incêndios, atendendo à relevância da interoperabilidade entre plataformas BIM.
Em complementaridade, a metodologia envolveu a tradução dos requisitos regulamentares do artigo
10.º (Locais de Risco), anexo III (Categorias de Risco) e artigo 18.º (Áreas Máximas de
Compartimentação) em fluxogramas de raiz logicamente estruturados, e posteriormente
implementados em três questionários online interativos desenvolvidos em linguagem HTML. Estas
ferramentas, testadas e validadas por técnicos de SCIE, permitem orientar profissionais nas suas
atividades profissionais, reduzindo erros de interpretação regulamentar e uniformizando critérios de
classificação.
This report resulted from a collaborative curricular internship between the Instituto Superior de Engenharia do Porto and the company VN2R, with the main objective of analysing methodologies for integrating information in BIM models for fire safety verification, with a focus on fire compartmentation. To achieve the mentioned objective, it was necessary, initially, to study the Portuguese regulatory framework for fire safety, namely Law No. 123/2019 and Ordinance No. 135/2020. The classification criteria for usage types, risk categories, risk locations and maximum areas of fire compartmentation were analysed, highlighting the critical variables necessary for regulatory verification. The case study consisted of a two-storey residential building, including residential divisions and an integrated garage. Through this BIM model and using Autodesk Revit, it was possible to evaluate four distinct methodologies for representing fire compartments: Room Tool, Spaces & Zones, Area Tool and external extensions. In a subsequent phase, automatic scripts were developed in Dynamo through four iterations. The integration of the process with the IFC format was also explored, using properties such as IfcZone for compartment grouping and custom properties to store fire safety data, considering the relevance of interoperability between BIM platforms. In addition, the methodology involved the translation of regulatory requirements from Article 10 (Risk Locations), Annex III (Risk Categories) and Article 18 (Maximum Fire Compartmentation Areas) into logically structured flowcharts from scratch and subsequently implemented in three interactive online questionnaires developed in HTML language. These tools, tested and validated by fire safety technicians, allow professionals to be guided in their professional activities, reducing regulatory interpretation errors and standardising classification criteria.
