This is the southwestern coast of Canada, we get very mild winter temperatures at this time of year ranging from 0-10 degrees C. We hardly ever get snow, and the thermometer rarely dips below 0. We're basically like Seattle.

It could be -10C and we'd still be able to work outside, although it would be a little uncomfortable. There's something called adding layers... and 15 minutes into the work you don't feel the cold.

Below freezing temps would make some jobs difficult for sure. I.e., Anytime you want to use water, you have to be aware that it could become frozen, possibly damaging pipes, material... Material in general can become difficult to work with. Temps right now are above freezing, so there are no problems.

0 Celcius is too cold. However im more worried about the concrete, is most of the concrete done or is there special ways to do it with the cold (i know about the styrofoam, but i think that only works to 0C not below). Thats more what i mean.

And seattle is too cold.

Don't worry about the concrete. Vancouver has been in the construction business for years. I can't answer your question about concrete and cold temps. It's never been a major issue here, at least from what I've observed. Temperature would likely have an impact on how long things cure, but other than that I don't know much more.

cold has an uncanny ability to make the concrete brittle and break like a calcium starved bone... at least in my experience.

Im sure you guys just use less water in the mixture, but inquiring minds want to know !

I don't call it cheating, rather provincial and federal subsidies/equalization payments.

Looks like they didn't cheap out on the glass facade afterall....the glass goes all the way to the roof:

2008-11-23 - Richmond - Brighouse Station
































I quite like it.

That's why you don't enter the cheat codes... You go to simptropolis and download the Simolean tree... plant the simolean tree and money grows for you. That's not cheating now is it? =)

On another note, I mentioned in SSP, Stadium and Main St. should be the next stations having the TV screens installed.

I know that sometimes concrete is covered and then warm air is blown between the concrete and the cover until the concrete is solid. Less or more water, you still can't make concrete properly in very cold conditions unless you warm it up.

From the Canada Line website - pics inside 3 stations - lots more pics at the links

Waterfront Station:

South Exit (next to UK Building)


Vancouver City Centre Station:

This is where the down escalator would be installed if they do so in future (open space for now):

... Actually I think that 15,000 ppdph is rather low, considering the investment going into the system. I think it may max out in the next 10 -15 years, which is hardly a life for the Billions of dollars going into it. How nearby would a twinning line go in? Would they consider Granville? (20 years from now)

What is the B-Line running at these days? 9,0000 ppdph?

The 98 B-Line runs at something like 2,000 pphpd during peak.

What I don't understand, and find pretty hilarious, is that he speaks normally in other sections of this forum. It's only when he bashes Vancouver that he turns on the garbled, cracked-out, cat-in-the-hat BS. Example from the Canada section:

Mind you, what about those clustered business districts up Yonge and the Don Mills one (plus others I might miss mentioning here)? Surely a fair number of their daytime inhabitants there would ditch their vehicles were regional rail services reintroduced through Summerhill, no?
So my question to Trainrover is why not speak normally all the time? At least if you had some constructive criticism people would actually be able to understand you.

And the 99? I dunno.... I just see the potential for some pretty huge density nodes along the RAV corridor. If the 98 has 2,000 and the 99 (more?) and the 99 runs to an end-desitation with a daytime popultion of 50-60K... the RAV has shockingly high potential ridership .I'm concerned 15,000 pphpd will happen much sooner.

I think it it very reasonable to expect extraordinarily high traffic on the RAV.. If Vancouver is going to allow big growth in the next big development wave, transit-oriented growth, the rapid transit corridors are the logical place for that to go.

BTW the station pics look great. I can't wait to see them in person when it is open! After recently riding the NYC subway I am very grateful for high quality modern, accessible stations. Are they leaving space for fare-control measures? I know Vancouver doesn't use them now, but that may change..

The 99 might be something like 4,000-5,000 during peak hours.

There's a reason why they built the Broadway-City Hall Station of the Canada Line so big and spacious, as seen in the above pictures.

The 15,000 pphpd should be fine, though when the Canada Line opens it will have a capacity of around 8,500 pphpd. 15,000 can only be achieved with longer cars and more trains AND platform extensions. The Millennium Line currently runs a capacity of something like 8,000 pphpd as well.

It'll be fine (or at least I hope, in the past this has been my worry as well). Consider that 15,000 pphpd is the peak hour capacity of the Expo Line, that's a lot of capacity and I highly doubt we'll see that anytime soon with the Canada Line.

I would be more concerned with platform crowding at some of the more busier stations.

We probably wouldn't see capacity issues until the M-Line is extended to UBC with a major interchange at Cambie and Broadway to Broadway-City Hall Station.


And yes, future fare gate spaces have been designed into all of the stations (same goes with the M-Line)....example:

Those new station interior pics are great. For the most part they look much roomier than I was expecting. I can't wait to check out the Canada Line once it's done. I'm even thinking of trying to find a new place around Cambie next summer.

While I realize any temperature that doesn't make you sweat is probably too cold for you, it rarely gets below 0C here so I don't think it's a major construction issue. Right now it's 12C (53.6F) here while places much further south like Chicago (which is at the same latitude as the northern border of California) have already seen snow this year. Construction never stops during the winter so I assume when it eventually dips below 0C we do something along the lines of this article I found:

Quote:
COLD WEATHER CURING

Concrete can be placed safely throughout the colder months if precautions are taken. During colder weather, the mix should be adapted to the ambient temperature by heating the concrete, adding accelerators, and providing protection. From November 1 through March 15, Mayco heats all concrete to meet the requirements of CSA and to maintain reasonable setting times and strength gain. Mayco's Polarcon™ is an accelerating system, which decreases setting times during cold weather.

Concrete generates heat during hydration, the chemical process by which cement reacts with water to form a hard stable paste. Hydration is affected by initial concrete temperature, ambient air temperature, the dimensions of the concrete and mix design. The temperature of the concrete during and after placement is critical since concrete sets more slowly as the temperature drops. Finishing and form removal may be delayed in cool weather and strength development can be impaired if appropriate precautions are not taken.

Do not place concrete on frozen ground, on snow, or in freezing weather. If concrete freezes while in a saturated condition, surface problems like scaling, spalling or cracking can arise due to the expansion and contraction of frozen water inside the concrete. During freezing weather, water curing of concrete should be terminated 12 hours before the end of the protection period. Do not use a curing agent if there is any chance that the concrete will freeze during the curing period.

Protect concrete from freezing temperatures for 3 to 7 days after placing.
Leave forms in place as long as possible. Corners and edges are most vulnerable (cover and heat if necessary).
Protect flatwork by covering and heating, or using insulated blankets, or covering with plastic and straw.
This information has been provided to assist you with your cold weather construction. For a complete review of cold weather concrete practices, please refer to CSA A23.1 – 94 Section 21.

look how long it took the expo line to dense up

and in vancouver it has barely densified up - perhaps joyce station but the rest of the vancouver stations haven't densified up in over 20 years

I don't forsee the RAV line being any quicker to densify than the expo line - oakridge has the most potential to do so

and marine drive could do it

the rest of the stations probably not in the near future
