Comments on: The costs of Second Ave. construction http://secondavenuesagas.com/2010/01/14/the-costs-of-second-ave-construction/ A New York City Subway Blog Mon, 13 Feb 2012 08:03:51 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Joe http://secondavenuesagas.com/2010/01/14/the-costs-of-second-ave-construction/#comment-216522 Joe Fri, 30 Sep 2011 22:43:21 +0000 http://secondavenuesagas.com/?p=4784#comment-216522 As I mentioned earlier, hard rock often makes tunnelling easier than wet soil. London was hardly completely rebuilt after WW2. We're not talking Hiroshima here. Some buildings were destroyed but most remain and the urban fabric is very much intact, underground infrastructure included. Tall buildings don't make much difference if you're just tunnelling under streets. Paris is also much older than New York, has a denser subway network, and has catacombs. The cost of construction in the NYC area is mind-boggling. The Tappan Zee bridge is another example of a completely unexceptional project costing at least five times more than it would in any other developed country, or even in another part of the US.

Drilling through soggy mud like in London is often much more challenging.

But other rail projects in the UK have been budgeted at several times as much as comparable projects in Continental Europe

That’s the outsourcing overhead. :-(

What the heck is going on here? Well, I guess that's a deep cavern station, but that only accounts for some of it.... is there seriously a "part 2" to 96th St. Station, and if so why does it cost nearly as much?!? A billion dollars for one station?

With all this stuff planned, buying two "MTA TBMs" and using them for all projects would probably have saved a lot. That’s a very good point.

Therefore I think it has a pretty decent chance of getting done, much much more cheaply than anything else.

London has had complete down-to-the-inch plans for the locations of all utilities since the mid-1800s, meaning that you get very little unexpected when you dig. Paris developed similar records later. Apparently not so for New York. That makes stuff absurdly more expensive. It still doesn't account for all the costs though.

NYC was built on solid rock making tunnel boring a lot more complicated. Other factors to consider are that london was rebuilt after being bombed in WW2, and Paris doesn't have tall buildings. Not quite an apples to apples comparison. London and Paris were both built on soil, so deep tunneling to avoid hitting utilities is easy.
