> The comparison to non-US based projects is inadequate
Can you explain why? For example comparing NYC's subway to Paris' subway. Why would one be more expensive than the other, since I don't think the base cost are that different
(I'm not from the US, I'm just trying to understand your point)
I think there are just a lot of intangibles so it's hard to compare mega projects, like the existing state of the subway where it is integrating into (like extensions), how many stations are being added, cost of labor, etc. I think comparing dozens of similar projects like the cost of replacing one street light, overpass or kilometer of highway from a non-US project, or even better within a single city in the same country, would be more informative.
