The potential of automated rule-based verification for fire safety measures in BIM

Abstract The aim of this study is the operationalisation of Eastman et al.’s (2009) code checking method applied to the modelling and automated verification of fire regulations for multifamily residential units in the state of São Paulo, using specific BIM tools. The method adopted was constructive research. The solution evaluation process applied the methodology in the verification of a five-stories H-shaped residential building in a social housing project built by the Housing and Urban Development Company of the state of São Paulo. The resulting devices are as follows: (i) a set of rules for fire safety code-checking for buildings with an area of over 750 m 2 and a height of 6 m to 12 m, which can be replicated to 90.8% of the remaining heights; (ii) a hierarchy to guide the coordination of the application of the various modules and rules on the object of study; (iii) a description of the required preparation of the BIM model; and (vi) clarification of the subset of model objects and properties needed for the automated verification process, which provides indications of a specific Model View Definition (MVD) for this code checking. The solution developed will make it possible to maximise the application of laws and regulations related to fire safety measures in buildings.

**摘要** 本研究旨在将伊斯曼等人（Eastman et al.，2009）提出的规范审核方法进行可操作化落地，针对圣保罗州多户住宅单元的消防法规建模与自动验证工作，采用特定的建筑信息模型（Building Information Modeling, BIM）工具开展相关研究。本研究采用的方法为建构式研究法。解决方案评估流程将该方法应用于由圣保罗州住房与城市发展公司承建的社会住房项目中的一栋五层H型住宅建筑的验证工作。最终形成的研究成果如下：（一）针对建筑面积超过750平方米、建筑高度介于6米至12米的建筑制定的消防安全规范审核规则集，该规则集可推广覆盖90.8%的其余建筑高度区间；（二）用于指导研究对象上各模块与规则应用协同的层级框架；（三）针对建筑信息模型（BIM）模型所需前期准备工作的详细说明；（四）明确自动化验证流程所需的模型对象与属性子集，为本规范审核工作指明了特定的模型视图定义（Model View Definition, MVD）方向。本研究开发的解决方案可最大化推动建筑消防安全相关法律法规的落地实施。
