Therefore formal requirements for buildings and technical rules in practice are examined and can be checked. For this purpose the open specification for checking functional requirements of a digital building model OpenBIMRL can be used. Architects or engineers may verify their BIM model with a pre-defined set of rules or entire rule-sets. This may be a set of rules for specific countries or usage (housing, commercial). In OpenBIMRL, functional requirements are formulated using a web-based platform separated from the actual rule checking engine. These rules consist of two main components: information extraction through predefined building blocks called Nodes, followed by the application of logical operations and comparisons. Previously, testing and verification of these rules on BIM models required a separate, non-portable program. To address this limitation, we conceived a redesign of the engine into a pure dependency structure devoid of user interaction. A server-client architecture was chosen with a RESTful endpoint. This change enables rule creators and end-users to view the outputs of defined rules and their respective Nodes directly in a concise format and within the 3D model itself.enhttps://creativecommons.org/licenses/by/4.0/automationBuilding Information Modeling (BIM)functional requirementsArts::720: ArchitectureComputer Science, Information and General Works::004: Computer SciencesTechnology::621: Applied PhysicsAdding an extensive feedback loop for the creation and validation of functional requirements of BIM modelsConference Paper10.15480/882.1355010.15480/882.13550Conference Paper
