A big mall like Villaggio was constructed based on the design and as approved by the Civil Defense Department (yes, all plans passes through CD prior to given a permit to start work). The designer or consultant already based their specifications and design criteria on what foreseen to be the mall when it is operational.

But of course the mall at the start is not yet leased individually except for the big areas pre-leased by whoever. But for the small other shops, all are provisions including all the facilities such as electrical, plumbing (if it needs if the area is allocated for eateries or restaurants) etc etc. But as a whole, there are general requirements such as fire sprinklers, smoke extraction fans pressurized escape routes and exits etc etc.
