Monorail

This project involves advanced engineering analysis for a major Monorail system, covering five passenger prototype stations, an Administration building, and a massive 13,000 m² Main Depot. The scope focused on utilizing Computational Fluid Dynamics (CFD) to verify the design of smoke management systems and precision cooling units. The analysis covered a mix of “Closed” and “Open” station types, as well as critical Data Center rooms across all buildings.

The main challenge was the extreme variety of environments we had to simulate. A fire behaves very differently in an “Open” station, compared to a “Closed” underground-style station or a high-ceiling industrial Depot. We had to prove that the roof-mounted fans were powerful enough to pull smoke up and away from passengers on the platforms, effectively clearing the escape routes. Additionally, we had to ensure the cooling systems (CRAC units) in the Data Centers could handle the heat load without leaving any “hot spots” that could damage sensitive equipment.

We created detailed 3D computer models to simulate real-world fire and airflow scenarios before a single fan was installed. For the stations, we verified that the extraction systems successfully lifted smoke from the platform and concourse levels, keeping the air breathable for evacuation. For the Data Centers, we mapped the airflow to ensure the cooling units provided even coverage. This “virtual testing” confirmed that the designs were safe, efficient, and fully compliant with safety standards.
