Dubai Metro

This case study illustrates our instrumental role in the EXPO 2020 Metro project, highlighting our BIM services' adaptability and precision. We collaborated with a variety of subcontractors across several sectors, surmounting complex modeling challenges and delivering on time, contributing to the wider vision of EXPO 2020 and UAE.

Background

Being a Roads and Transport Authority project

We worked in conjunction with a variety of subcontractors across diverse industries to deliver different aspects of the EXPO 2020 Metro project. Our collaboration spanned various verticals, such as wayfinding, landscaping, architecture, structure, MEP (Mechanical, Electrical, and Plumbing), and rail elements.

Challenges

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.

Landscaping

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.

Signage

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.

Proposed Solution & Implementation

Navigating through the challenges, we devised comprehensive solutions to overcome technical difficulties, capitalizing on our perseverance and innovation in each of the three key areas.

Landscaping

For the landscaping sector, we dealt with the complexities by focusing on breaking down tasks into manageable parts. To model detailed natural elements, tile patterns, and key MEP assets, we used the granular detailing capabilities of our BIM software. In creating landscape gradients, we exploited the software's engineering-level precision features, enabling us to model complex drainage and water management systems.

Signage

In the signage sector, overcoming the challenges demanded a meticulous approach. We leveraged the capabilities of our BIM software to build accurate models of a variety of wayfinding elements. To ensure accessibility and compliance, we utilized features allowing us to check viewing angles, distances, and the legibility of signs, thereby achieving visually consistent and correctly located signage models.

Rail

Addressing rail sector challenges in Bentley's OpenRail, we adopted a phased approach for modeling track alignments and switches, validating accuracy against reference models. To handle dynamic track conditions and intricate interlockings, we used OpenRail's simulation capabilities for accurate modeling.

We addressed varying rolling stock compatibility using OpenRail's flexible modeling environment, creating multiple configurations within a single model. OpenRail's safety-checking and accessibility features ensured our models met safety standards and were usable by all personnel.

These technical solutions, paired with team training, helped us overcome challenges, leading to the creation of quality BIM models in the rail sector.

Results

This case study highlights our journey through a series of challenges and solutions in creating BIM models in signage, landscaping, and the rail sectors. Despite initial hurdles, particularly with the unfamiliar Bentley's OpenRail, our strategic, phased approach combined with the adoption of innovative technical solutions enabled us to deliver high-quality models. Continuous team training further enhanced our proficiency. Our perseverance and commitment to overcome these challenges underscore our dedication to delivering quality, demonstrating our ability to navigate complex scenarios and deliver on our promises, no matter the difficulties encountered.
