There are doors and there are doors. I have been in transit systems where the doors are at waist height (high enough to be a barrier but still climbable) and others were they are part of a floor to ceiling barrier. The former kind clearly require less (or no) ventilation changes, the latter do.I concur w/this; though would note, a whole of ventilation improvement has been invested in for the last 10 years;
Also, the project scope should be the same now as 10 years ago, but the estimates per station are over triple (inclusive of future year inflation); on constant scope, that rate of increase seems dubious.
