Automated Compliance Checking System for Structural Design Codes in a BIM Environment

This study proposes a framework for developing an automated compliance checking (ACC) system that supports the verification of structural calculations in openBIM format. The framework consists of four main aspects: 1) classification of design codes depending on structural components and limit states to be checked; 2) preparation of a structural model according to Industry Foundation Classes; 3) interpretation of conditions in design codes into a machine-readable rule language; and 4) design of an ACC system, with a focus on the rule flow in the structural design code. The framework was demonstrated through a detailed example of an ACC system using ifcOWL, SWQRL, and the Drools inference engine. The ACC system was developed to check the strength and serviceability of a prestressed concrete girder bridge and its components. The developed ACC system verified the actual design example. The proposed framework can help develop ACC systems in structural engineering and can be customized to meet user requirements and accommodate various data sources and design codes.
