NCR builds plenty of shit too, you're aware that Shady sands (largest city they have) is exclusively post-war constructions right?Why would that suggest better buildings would be more common place? The best buildings in the Post War literally come from people use nuclear reactors that easily blow up said base.
The NCR in New Vegas still relies on using pre existing structures instead of building their own after five years of being in the Mojave and sending over a thousand people each year there.
If the NCR with substantial man power can't do it because they're too far from their core territory why would the less numerous and less unified East Coast people be any better?

Uhhh all over the fucking place? When like 9/10 of humanity has been destroyed, that's a lot of houses to scavenge for pipes and you can use all sorts of shit as filters, sand, gravel, carbon, etc. Filters aren't rocket science. XDWhere are people getting the filters and tubes from?
Protip, the faster something emits radiation (AKA, the more radioactive it is), the quicker it loses radiation emissions.Your average FO nuke is radiating anywhere from 20-250 rads a second AFTER immediate detonation,

The IRL nukes are outputting a lot less than that and expire much sooner, not to mention the East Coast got hit by more nukes than the West.
