While technically the second largest, this venue takes the crown for total floor area . Unlike the specialized cricket or football stadiums in the west, this multi-purpose venue includes a massive athletics track and a separate indoor swimming pool within its shell. For MEP engineers, the challenge here isn't just the size—it's the age. Maintaining air quality and humidity control in a 1989 concrete behemoth with a fabric roof is a daunting retrofit challenge.
If a list includes all venues regardless of shape, the Indianapolis Motor Speedway (approx. 257,325 capacity) and the Bristol Motor Speedway (approx. 153,000) would top the list. However, BIMsmith and architectural firms often categorize these as "Speedways" or "Circuits" rather than traditional stadiums, excluding them from standard stadium rankings.
