Optimizing Road Infrastructure Design using I-BIM Technology

Abstract: Infrastructure Building Information Modeling (I-BIM) has emerged as an important supporting technology for managing infrastructure project design, construction, and operation. This paper presents the development of an I-BIM model that can holistically capture the components and their integration characteristics of a road project. Extending previous works, the development deems to provide detailed road design analysis including drainage, signage, and lighting, traffic lanes of variable width, inclined pavement layers, vegetation and plantation, etc. In addition, the difficulties in developing “irregular” components and aligning them with each other and with the longitudinal land terrain are examined.
