A BIM-Based Framework for Code Compliance Audit of Universal Accessibility Design Requirements

Abstract

The study aims to enhance the Universal Design evaluation process by leveraging Building Information Modelling (BIM) to automate accessibility assessment for buildings. With a growing aging population, increased disability prevalence, and the necessity to accommodate diverse travelers, Universal Design Evaluation gains importance. However, traditional manual evaluation methods exhibit errors. BIM, as a comprehensive 3D model incorporating building information, offers a practical alternative for assessing universal accessibility. This study proposes a framework utilizing BIM to measure accessibility in both existing and new building plans, aiming to ensure Universal Design principles are incorporated. By automating accessibility assessment through Dynamo using BIM data during the design stage, can potentially lead to significant reductions in time and labour for review, enhancing the proficiency of the evaluation process. Additionally, BIM facilitates early identification of accessibility issues, minimizing adverse effects of design changes during construction. The transition to automated BIM-based checking systems not only streamlines the design approval process but also promotes transparency within the Architecture, Engineering and Construction (AEC) business, signalling positive advancement in Universal Design implementation. Persons with disabilities (PWD) constitute a significant portion of society, necessitating comprehensive support, including accessible environments, and full inclusion in all spheres of life. Despite existing accessibility codes, the absence of an accessible system for PWD highlights systemic challenges. Automated code checking emerges as a critical phase in the design and construction process, requiring standardization and technological advancements. By integrating Universal Design and BIM, the study seeks to optimize accessibility and minimize the need for future renovations, emphasizing the necessity of automation and digitalization in enhancing inclusivity and efficiency in architectural design and construction processes.
