As work resumed post-Covid with new subcontractors, we encountered a host of complex modeling challenges that spanned across all disciplines of the EXPO 2020 Metro project. For the purpose of this case study, we will delve deeper into the unique challenges in two critical areas: landscaping and signage.
Our team grappled with complex landscaping modeling tasks, such as exact tile patterns, MEP assets like lighting and wiring, and modeling high-detail natural elements. Creating landscape gradients for effective onsite drainage was another crucial challenge.
The signage sector demanded accurate modeling of a variety of wayfinding elements, such as directional, informational, and regulatory signs. Ensuring legibility, visual consistency, correct location, and accessibility to all, including those with disabilities, were key aspects considered.
Track & Signalling
Mastering Bentley's OpenRail brought about technical challenges. The precision required in modeling complex track alignments and signaling systems was demanding. Our team struggled with replicating dynamic track conditions, and correctly positioning intricate interlocking systems was a tough task. Accommodating varying rolling stock compatibility within models was another hurdle. Overall, these technical challenges demanded a deep understanding of OpenRail, which was challenging but essential for quality BIM models.
