Why podium areas need their own lines
A podium deck collects things no internal area does: leaf litter, wind-blown rubbish, bird droppings, food from residents and workers using the space, and standing water where drainage is imperfect. It also has furniture that gets moved, planters that shed material and a surface that is usually paver, tile or timber decking rather than anything found inside. None of that is covered by an internal task list.
Grouping it under common areas therefore produces a poor result, because the person pricing a common area scope is picturing corridors and lobbies. Naming the deck separately, with its area, its surface and the items on it, is what makes the work realistic. It also lets a building decide how much attention the space genuinely warrants, which varies enormously between buildings. It also lets the cost sit where the responsibility does.
