Yes, but we've already crossed that bridge, haven't we? The big universities are on the margins of the city, and it's too late to change that. The downtown campuses you mentioned are tiny compared to a full campus. How many $billion would it cost to build a landmark campus for, say, 15,000 students on the flats by Finning? Honest question - I'm guessing $2 billion wouldn't get us very far, but I have nothing to back that up. Whatever the cost is, it would be way cheaper to build a 2nd whole university in the endowment lands, or to build up Langara into a world-class campus, or a similar use of cheaper land.

Can someone tell me, if 10th Ave is the route under consideration, why boring is the preferred option (among those at the 'I support Extending SkyTrain to UBC group)?

I thought the point of boring was to not disrupt traffic along Broadway. If 10th is the chosen route (which it should be) why not use cut and cover?

I've always liked the idea of turning International Village into a satellite UBC university campus...it's a huge building, go after the SFU Surrey model.

$2-billion could actually build you a pretty substantial campus...though it's residential, just think about how much we can build with $800-million for the Olympic Village.

Most urban campuses are built piecemeal or added to by purchasing and renovating older buildings, much like SFU has been doing downtown. There would be no need to build a unified set of buildings all at once for a landmark campus. It could even start, as has been planned, as a combined campus of Emily Carr, UBC, SFU, and BCIT (or whatever the institutions are/were), then become a separate university later.

I suspect their support for boring under 10th Ave is a reaction to criticism of cut-and-cover on Cambie. One of the advantages of cut-and-cover, it's shallowness, would fit nicely with station entrances on Broadway. The stations could be like storefronts facing Broadway, like at Broadway-City Hall, housing TVMs and ticket validators with lightly sloping ramps up and down to stacked platforms and tunnels under 10th.

Of course traffic on 10th Avenue would be disrupted, but it's already a bikeway with extensive traffic calming. Most of the traffic is bikes, and they can be diverted to 13th (flatter and on top of the hill), for example, or the existing bikeway on 7th (flat but at the bottom of the hill). Traffic will be disrupted at each station house even with a bored tunnel.

That's why I thought the route was moved to 10th, because cut and cover wouldn't really disrupt any traffic (except cyclists) and are there really any businesses that will complain along 10th before Alma?.

If you aren't doing cut & cover, I don;t think the problem is as big. Areas to not have cut & cover would be west of Macdonald.

The costs of cut & cover and tunnel boring are actually quite close but cut & cover is a lot faster than tunnel boring. One reason why the cut and cover of Canada Line was so negative is because the entire road was torn apart. Instead of ripping the entire road apart, if you do it one by one, it wouldn't be as big as a problem: that being said, doing it that way is slower.

Cut and cover really isn't that much cheaper. It just can be built faster and is easy to meet a deadline. If you run behind schedule, you just start another front.

Also, most of the way from Main to Alma, the properties on 10th have alley ways behind them. And I believe any building along there new enough to have bellow ground parking as the access from the alley.

So I don't think cut and cover would interfere much with normal life in many parts.

Also, if you do it in segments starting in the east and moving west we wouldn't need to close the entire road, and could even open stations as they come online. The entire project might take longer, but if there were continuous results, I think it would be better to have a station or 2 open every year than have the whole thing open at once in 2020.

question about side platforms and centre platforms. if a boring machine is used, would that mean stations will have centre platforms? whereas cut and cover would mean side platforms

Phase one, connecting with the Canada Line, should start construction as soon as funding is available, such as the federal gas tax collected in Metro Vancouver.

It depends on how the tunnel is bored. For instance, if we are using two smaller tunnel boring machines, then the platforms would be in the centre. But if we are using one large tunnel boring machine (capable of holding two tracks), then side platforms would be used.

As for Cut & Cover, both side and centre can be used, but it is usually side platforms. It really depends on how the tunnels are constructed, the size of the stations (as in, the pit for the station), and the amount of money you have.

With regards to the False Creek Flats university idea, would newcomers please take a look at this thread:http://forum.skyscraperpage.com/showthread.php?t=154696 It is unfortunate the photos are no longer there, but the reading is still worthwhile.

And for my two cents...

From VCC Clark > Fraser St: Elevated transitioning to grade
Fraser St > Great Northern Way site (henceforce known as GNW Station): At grade transitioning to bored tunnel through future Great Northern Way development. TBM inserted on site
GNW Station > 10th & Yukon: bored Tunnel. TBM extracted on CoV parking lot site.
10 & Yukon > 10th & Alma: Cut and Cover.
10 & Alma >10th & Sasamat: Bored tunnel. TBM inserted on old Shell gas station site.

Two smaller tunnels running at different elevations (i.e., stacked) would result in side platforms. Or you could also, in theory, turn a middle platform into two side platforms, by simply installing a wall down the middle, not that it would be the logical thing to do.

Not every building. Some blocks have no curb cuts. Some have a couple. VGH emergency is accessed off 10th near Laurel as is at least one loading bay. There's a firehall on 10th between Hemlock and Granville. City Hall has a parking entrance on 10th. There are also maybe five to ten apartment buildings in total between Main and Arbutus with parking entrances off 10th.

As long as the stations are cut n' cover, does it matter whether a bored tunnel or cut n' cover is used between stations, as the stations themselves would be shallow stations, right?

Comments:

TBM probably won't work near GNW Station - it's all landfill and probably too soft/unstable for a TBM. I would expect cut and cover until the turn south under Prince Edward St (staging area north of GNW @ Prince Edward St).

Tunnel could be bored to 10th & Blanca - TBM exit site could be on University Golf Course land. The station at Sasamat could be largely under the street with an exit on an expropriated retail site. Having the TBM exit off to the side would require the demolition and expropriation of a larger number of retail properties. Alternatively, the TBM could be extracted from an in-street pit, but that would cause more traffic headaches.

Arrrrrrrrgh!

Arguing against Skytrain under Broadway and using the London DLR as your case study?

Hello! Are you there McFly? Think will ya?!

The DLR is a fully automated, fully grade separated, medium capacity rail way. The exact same thing as Skytrain! The only difference is that the DLR stations are closer together, about 750m from each other. Which is something we could do with Skytrain if we wanted. And Skytrain has a much higher capacity and is more successful than the DLR.

I can't tell if he is arguing for or against Skytrain anymore? Or is he saying that first we spend hundreds of millions on a slow system, THEN build the subway once it is proved he is a moron for not building Skytrain first? Why not cut to the chase and build Skytrain right away, no need to build a system that will be obsolete by the time it opens.

The reason it was so cheap was because it was built in a run down industrial part of town, that was then redeveloped. And they didn't build the DLR as a first step, it was an accident it was so popular. The system was too small for a growing mega city like London, so they had to augment it with a Subway.

And the lack of developments around stations in Vancouver is the Vancouver's problem, not a Skytrain problem. The city of Vancouver is deadly slow at developing land and rezoning. It will happen eventually, especially around some Canada Line stations, but if you want to see what Skytrain can do look at New West or Metrotown or Joyce, or Guilmore/Brentwood/Holdom.

There will be development around stations on Broadway, as pieces of the land, especially on Broadway are already zoned commercial (its easier to rezone commercial to mixed use high density than low density residential to something else). Just look at all the building that HAS happened on Cambie South of Broadway, and all along the Broadway Corridor from Cambie to Burrard. There is room for much more than Skytrain can help make a reality.
I will second your arrrrrghhh. I will call bullshit on on commuters preferring an elevated DLR station to a tube station. All they want is access to a frequent transit service and will pay a premium to be within easy walking distance. There is a reason that Rightmove, the UK's biggest property website allows to search for properties within 1/4 and half mile distances from a station.

Also I hate the hindsight bullshit about how the Jubilee line extension was inevitable. That the DLR was built to small etc. It's a woeful ignorance of how the former docklands came to be the new city it is now.

The problem for the Docks is that they were situated in the the big loops that the river makes downstream. This meant that all this now empty land was far from the main railways and roads that bypassed them to the North and South.

The Docks were isolated and the communities that lived there were isolated from the rest of the city.

Previous regeneration schemes of the 60's and 70's had failed to take off. There are many interesting books (well, to an urban geographer) on the blow by blow accounts of how this came about and how the Docklands developed but I'll keep it brief.

Those put in charge of regenerating the area had to find a way of opening up the docks for redevelopment. At the time it was envisigned that the Docks would become the typical inner London full of middle tier support companies occupying crinkley metal sheds providing catering, PR, trades and incubator space for new businesses.

Now modelling suggested that the low level of development just needed an enhanced bus service. But agencies involved argued that to change opinions about the East End (urgh dirty and nasty) you needed a high profile sign that change was permanent.

They argued that a light rail service would boost demand and more intensive redevelopment would take place. So they cobbled together some former freight routes with some new viaduct over the docks and built the initial railway for just £77 million. Which was cheap even in 1987. Little did they realise what they had unleashed. Suddenly apartment blocks and low rise office blocks were sprouting before it had opened and they started planning platform extensions.

The DLR has been continually expanded since it has opened and now carries 60 million passengers up from 7 million. By the time the latest expansion works are done close £2 billion would have been spent and passenger numbers should be around 100 million. Now with hindsight they could have built it one go and could saved them selves some money in construction. But such a huge investment would never have been approved without any obvious demand.

The lesson to be drawn, is build for what you can support in passenger number upon opening. But leave enough space for expansion. If allow as much development as possible near transit, then watch your passenger numbers soar over the years.

. . . . .

May I say I agree in principle with these two members? They both show foresight and common sense:

1: Build it underground, not on columns, stilts, or down the middle of the street.

2: Plan for the future, and build it big enough. The Canada Line (all the way from Paris) already seems prematurely small with short platforms and two-car trains (which, yes, I know, can be made into three-car trains. Wowee)

Foresight, aesthetic prowess, and the capacity to, as Samuel Goldwyn (MGM Studios) said; "Do it big, do it right, and give it class."

Something Canadians (Vancouverites anyway) just can't seem to grasp, by and large. Excuse the superciliousness, but these posts seem to know what they're talking about, and living in Paris, with a dense Métro system, a long-haul, high-speed commuter subway (the RER) plus commuter trains of all stripes, I have seen a successful transit system up close, and ridden on others that work because of the foresight that was put into building them. Too bad the province is nearly broke, and the people think small-town.
