ABSTRACT
The digitalisation of building permitting processes has a significant potential to improve efficiency, transparency, and accuracy. One of the key components of building permitting digitalisation is Automated Compliance Checking (ACC). However, transforming regulatory requirements into machine-readable formats to enable ACC processes remains a challenge due to the complexity and variability of legal texts. This chapter examines the application of the Information Delivery Specification (IDS), an open standard from buildingSMART International, as a bridge between regulatory requirements and Building Information Modelling (BIM)-based ACC. IDS enables the definition of information requirements for BIM models in a standardised, machine-readable format, which facilitates both information availability checks and some logical dependencies. While IDS supports formal and logical checks, limitations remain in some cases. These include handling exceptions, complex dependencies, and spatial checks. Two implementation cases, drawn from the City of Vienna and Nepal, are presented to illustrate practical, real-world applications of the proposed approach. The chapter also discusses the importance of combining IDS with complementary tools and rule-based methodologies to achieve comprehensive ACC process in building permitting. Interdisciplinary collaboration among legal, domain, and Information Technology experts is essential to develop accurate, interoperable, and scalable digital permitting solutions. Overall, IDS represents a promising step towards harmonised, efficient, and transparent building permitting processes, with potential for further enhancement through extensions and integration with openBIM standards.
