Computer representation of building codes for automated compliance checking

Macit İlal, Sibel / Günaydın, H. Murat

AbstractDevelopment of automated building code compliance checking systems requires appropriate representations for building codes. Building codes are complex documents written in natural languages, and the development of computable representations is challenging. This paper presents a new model and an accompanying modeling methodology for the representation of building codes that may be utilized in the development of future automated compliance checking systems.The new model combines the semantic modeling approach of the SMARTcodes project with the theoretical foundations established by Nyman and Fenves, namely the four level representation. This hybrid model organizes the representation in four levels and allows for separate modeling of domain concepts, individual rule statements, relationships between rules, and the overall organization of the building code.The model is evaluated with a case study. The İzmir Municipality Housing and Zoning Code is chosen as it is representative of complex building codes that are in effect throughout Turkey. The formalizable rules in the section of Izmir code that apply to all types of buildings, are represented in computer implementable format based on the new model. The research presented in this paper shows that decomposing a building code into four levels and modeling rules based on the semantic-oriented paradigm is an effective modeling strategy for representing building codes in a computable form.

Highlights•A new hybrid model and methodology for representing building codes is presented.•The model modifies the semantic representation based on the four level paradigm.•Four level decomposition helps eliminate inconsistencies and redundancies.•The model is independent of checking systems.•The Izmir Municipality Housing and Zoning Code is used as a demonstrative case.
