Rule Checking Method-centered Approach to Represent Building Permit Requirements

Abstract

This paper aims to describe rule checking method, classification and its demonstration. As applications of BIM extends, there have been some challenging projects on automated building compliance checking. The current rule-making method is developercentered and thus is difficult to define rules without propound programming knowledge. This paper introduces high level rule making methods with law sentence-centered approach. The proposed methods have intuitive naming convention and are directly mapped with the predicate of the law sentences. Therefore, it is easy to infer function of the methods. According to the type of object and property in instance level, three hierarchies of method classification were set: 1) level 1 divides types of instance, 2) level 2 classifies the type of property, and 3) level 3 specifies the content of checking. From the level 3, representative rule checking method is defined. The representative method is subdivided into extended methods according to the specific object and property to check. The rule checking methods are combined together to form an intermediate pseudocode. The pseudo-code is later to be parsed into computer executable form. This paper mainly focuses on 1) introducing law sentence -centered rule checking method, 2) object and property-based classification of rule checking method, 3) method extensibility and 4) demonstration of rule checking methods with actual requirement sentences from the Korea Building Permit. The high level rule checking method is developed as a part of KBimLogic. KBimLogic is a software that translates the Korea Building Permit requirement into computer executable format. KBimLogic is now under development with government funding.
