Abstract:

Automation of the code compliance checking has been explored extensively, particularly in recent years with the emergence of building information modelling (BIM). Still, automated code compliance checking has not yet been fully realized, as there is no standardized method for rule interpretation and building model preparation for code compliance. Manual verification of design code compliance, meanwhile, requires significant effort and time and is error-prone, while uncertainty and inconsistency in assessment lead to delays in the construction process. In this paper, the development of a prototype to automate municipal bylaw and wall framing code compliance checking for residential building is presented. The building rules have been classified into three groups based on the complexity involved in translation into computer-readable format and complexity in retrieving the required information, and they are represented based on building objects, which makes the regulations easier to understand and assists in translating the regulations into a computer-readable format. By creating a model view based on the required element’s parameters extracted from a model for checking purposes, the prototype application offers automated code compliance checking functionality to validate designs based on building code requirements and construction engineering specifications. The implementation of the prototype and its benefits compared to manual checking is demonstrated.
