They are not talking about “mechanical” systems such as HVAC, they are instead describing a “Mechanically attached roofing system”. That’s a specific term, and covers metal roofs of a specific type and construction.
Concrete is a superior substitute. Concrete deck your datacenter and you’re done. It’s considered pretty bulletproof. Figuratively and literally.
Our DCs have concrete floors walls and ceilings.
