At the beginning of 2024, Accord project released the digital building permit ontology called Architecture Engineering and Construction Compliance Checking and Permitting Ontology. The Architecture Engineering and Construction Compliance Checking and Permitting Ontology (AEC3PO) offers a transformative approach to compliance checking in the AEC sector.
Digital building permit ontology modeling the complete spectrum of permitting and compliance checking and serving as the backbone for a domain-specific rule language and formalization methodology. Organized into thirteen detailed modules and nearly 80 classes, AEC3PO captures the essence of regulatory documents, outlining the rules within, and defining the specific check methods for operationalization.
It systematically structures each compliance statement, categorizing them by nature—be it numerical, human evaluated, or categorical thereof—thus offering a detailed representation of the multifaceted rules and regulations. AEC3PO is a vast network of 803 axioms, including 174 logical axioms that underpin the inferential logic of the system, and 118 declaration axioms to distinctly specify elements.
This ontology has been tested with regulations from demo countries such as the United Kingdom, Finland, and Spain, demonstrating its capability to bring semantic inclusion to the entire compliance checking process, a testament to its practical applicability and industry-wide significance, highlighting its role as the foundation of the rule formalization methodology that encompasses the entirety of the compliance checking process—from regulatory document modeling to compliance verification reporting.
The model will enable the industry to integrate technical solutions for automating compliance checking of buildings in their design, construction, and renovation/demolition lifecycle phases. This open resource is provided with the methodology for regulations’ digitalization that can be applied and is a critical stepstone for the digitalization of compliance checking in the whole industry. As an industry-aligned model, AEC3PO ensures seamless integration into both the construction sector and the European Legislation framework.
