Are you in Burnaby? (Edmonds or Metro?)

UBC launches campaign for SkyTrain extension 'all the way' to campus.
Check out the UBC Rapid Transit website.

I mean, if UBC offers up 1/3rd of the cash, it might actually be a possibility.

That's over a Billion with the latest estimates. I doubt it. I'd be pleasantly surprised if they offered $500M.

Charge a toll for people to drive onto campus

Good to see them still suggesting a 2nd station at South Campus:

Full Rail to UBC study is posted online:

https://www.translink.ca/-/media/Documen...9_01_24_technical_report_rail_to_ubc.pdf

A lot of detail in that report, perhaps the cost breakdown.

At-grade LRT = 70M/km
At-grade SkyTrain = 80M/km
Elevated SkyTrain = 140M/km
Tunnelled SkyTrain = 160M/km

At-grade station = 5M
Elevated station = 50M
Tunneled station = 100M

60% contingency!

i have always wondered where they get contingency numbers from... 40-60% seems very very very high to me. shouldn't we be better at budgeting then this?

even including inflation, that seems high.

It's quite standard practice to be using high contingencies at early stages of the project, given the potential risks without detailed designs.

yeah and i get that, but still, 40-60%? that still seems crazy high.

Seen this all the time in projects. The quotes always come in super low. Also with inflation being around 2-3% this contingency drops quite a bit.

Welcome to the tunnelling industry.

Anything geotechnical depends hugely on what ground conditions may be encountered. No matter how much money you spend on exploratory activities, you may still end up missing something which costs lots of money and time to mitigate. Most of that time, those activities also end up on the critical schedule path as well.

Yes but I'll be disappointed if that's all UBC wants to pay for.

Also, that's quite the corner on that map. They'll need some real estate to get the train turned like that, I wonder how well that has been mapped out.

WarrenC12 · #**9594** Posted **Jan 23, 2019, 3:53 PM**

So a $20M/km premium to put it underground? I think that's within the City of Vancouver's budget to pay for that premium. Perhaps another tax on high end west side homes that will benefit?

That doesn't seem even close to right to me. At-grade stations on the Skytrain system aren't that much smaller or easier.

For a recent example look at Moody Station (at-grade) vs. Burquitlam (elevated) on the Evergreen Extension.

Sheba · #**9596** Posted **Jan 23, 2019, 7:49 PM**

At the end of an article: "It hasn't been decided whether that line would run underground or on an elevated track." Oh suuure the west side will have an elevated Skytrain line. At most some of the line on UBC land might be on-ground or in a trench.

csbvan · #**9597** Posted **Jan 23, 2019, 7:57 PM**

By the time they begin construction on the line out to UBC, nobody will actually live on the West Side to complain about the elevated track.

I think that figure refers to the at-grade stations for the LRT options (but doesn't differentiate)

The write up says they haven't examined detailed routing. I think that map is just "connect the [station] dots".
If it's tunnelled, they'd need to keep it away from vibration-sensitive research labs (This was an issue at University of Washington).
I suspect Wesbrook Mall would be the corridor, as that leads to the village centre at South Campus, Main Mall is too close to engineering, and East Mall is close to hospital and biological sciences labs.

As a former civil engineer, the number I usually see is 30% contingency. 60% strikes me as ridiculously high.

It's for inflation too. Reasonable to assume that's half of the 60% number.
