Montreal Metro Laval Extension

It's been announced that the three new subway stations in Laval will open for service on Saturday April 28.
 
Montreal has mastered the art of concrete. They use it like no other city I've ever seen. Olympic Stadium, highway system interchanges, various office complexes, and the subway.


Yeah right... stadium with chunks of it falling, collapsing overpasses, worst highways you'll ever drive on, mob run construction (good example is in Vaudreuil, you have to drive well past where the exit should be to do a huge loop to get to the same spot were you could have been at 3 minutes earlier... nothing like bilking the public for senseless construction)...

thank God we haven't mastered it !!
 
^And don't forget the original concrete surface for highway 13 to Mirabel airport, a road with so much undulation that it would induce sea-sickness. The problem was solved when it fell apart and was resurfaced with asphalt.
 
For my part, I was making reference to the construction of a highway. Montreal's subway goes through considerable amounts of rock so in many cases there is an opportunity to construct a solid structure right from the start.

With respect to the Montreal Olympic Stadium, aren't most stadiums largely constructed from concrete? The concrete tower of the stadium posed a number of engineering problems, and there were a number of accusations that the structure as a whole would have a tough time standing up to Montreal's climate.
 
SimplyDan:

yes, agreed. Montreal uses concrete in a grander manner when constructing it's projects. There are a few other cities around the world that use concrete the way Montreal does, but not on Montreal's scale.

Olympic Stadium, the highway system, tunnelled highway under downtown, the subway stations: they are all done on a massive scale. There are endless photo ops.
 
Yeah, except that they spend a fraction of what we spend per mile.

I think it's a pretty large fraction though - 3/4s or 7/8s or so. Don't have the figures in front on me, but the original esitmate for the Laval extension was ridiculously low, and the budget was blown so much that an inquiry was held to determine how that all happened. Somebody, anybody, have the details handy?

According to the Montreal transit system's website http://www.stm.info
the cost had originally been budgeted at $803.6 million, for 5.2 km. of distance. Apparently it ended up being $745 million, or $143.2 million per km. The Sheppard subway in Toronto came out at about $155 million per km.

Direct comparisons are tough, but it looks like Montreal did pretty well, esdpecially considering that they had to go under a river.
 
Also note that the TTC claims that subway construction costs have rocketed to $230 million per km since the Sheppard subway was built. That's what they are projecting for York/Vaughan, even though much of it goes through undeveloped, government-owned land and doesn't have any natural obstacles of note. Forget Madrid, maybe we should be talking to Montreal about how to get our costs down.
 
Unimaginative, Montreal's metro trains are very narrow compared to Toronto's subways trains. In fact their trains are narrower than a standard city bus.

Widths
TTC subway: 3.135m
D40LF or Orion VII bus: 2.6m
STM metro: 2.5m
