1) The slanted guideway above Como Lake is not 100% fixed as of today. Its still slightly mis-aligned, but there were lots of workmen at both ends. So presumably they are still working on it. Whether it means more road closure, we don't know...

2) The guideways are in place up to the last of the Burquitlam Station beam. The last segment is still attached to the gantry crane so I guess the epoxy is still drying (though its been wet lately so I dunno how that will work).

3) There is only *ONE* column left to be poured between Foster St and Cameron. The rest are pretty much complete, with only the form on top of a column immediately south of Gatineau Place and a few of those square thingies on top need to be filled for the one south of that (and north of the steel guideways).

4) The stack of rails that I reported at the South Tunnel portal area seemed to have increased in volume. Maybe they will be used for the TBM and may be stored there while they reconfigure the North Tunnel portal area, but still seems so counterintuitive to store them there, only to move them later (plenty of places to put them in North Port Moody). I do feel that perhaps those rails are for the Skytrain, and they will start to instal them once the Como Lake guideway has been fixed.

4)
if the rails are being piled up at the South Tunnel portal area (near Como Lake and Clarke Road), I would expect them to be used on the elevated track guideways that the gantry crane has already built. As the gantry crane builds the elevated track guideways (heading south to Lougheed), more rails will likely be stored there just before they are installed on the new track guideways.

Since the TBM will take the rest of this year to complete the tunnel and then most of next year will be needed to finish the tunnel interior, I can't see these rails sitting and rusting for over a year while the tunnel is being built and finished.

Interesting article on EGL construction techniques:

http://www.canadianconsultingengineer.co...ouvers-evergreen-line/1002997439/?&er=NA

I am fascinated by the use of wood timber.

Not surprised by that as long as the wood stay wet it can last indefinitely. In Venice a lot of the piles are hundreds of years old, they only get damaged at the point where they are exposed to air. The sections under water are as good as new.
Interesting to see confirmation that the piles will help deal withliquification, I remember years ago reading that every tower that went up in Richmond helped counter the liquification concerns due to the pilings and the safest part of Richmond in an earthquake would be the densest areas.

Great post!

Thanks for posting.

Agreed! Thanks for posting the article, Olden Retreiver.

I wonder if the Evergreen Line construction will be featured in a Discovery Channel special. The replacement of the BC Place roof was...

The schedule for more works at Lougheed Station is now up.

Interestingly enough, it will take until July to finish up the Lougheed curved guideways, just in time for the gantry crane to reach Gatineau Place.

------------------------------------------------------------------------------
Nighttime Structural Work in the Lougheed Town Centre Station Area

Girders for the structure that tie into the existing SkyTrain system and travel up North Road have been set-up and crews will now install the concrete deck for this section of elevated guideway.

In order to avoid disruption to daytime transit service at the Lougheed Town Centre Station and due to the proximity of the guideway to existing SkyTrain operations, some nighttime work is required between late April and July.

For more detailed information on when nighttime work is planned - See more at: click

The first blue column form has been erected near Coquitlam Station, also the at-grade guideway excavation has reached Falcon Drive.

I'm sure that's no coincidence, but rather the result of a well thought-out plan.

Makes the Georgia Viaducts look sexy

[dpogue]

They were pouring concrete this morning. Trying to remember, I think it was in the first steel girder on the inbound.

Taking video from the front of the train doesn't show anything new at this point. I'll try to get a video looking backwards at some point.

Considering the unfinished monstrosity that was there before, that "fugly piece of engineering" is the most beautiful thing that has ever been put up in the area.

Yeah...isn't SNC Lavalin simply that great?

And what is so ugly about it? It looks like an elevated guide way found anywhere in the world (including the all so loved world class cities).

This is what functionality looks like people.

These structures are everywhere in Japan, and there is a reason why Japan constantly ranks as the worlds best rail system.

I am so happy to see this "fugly" engineering being built, for it means once again metro-Vancouver is expanding its mass transit with the correct technology

Regardless of the unique roof canopy, the concrete guideway design at Lougheed station is hard to fathom, even knowing the original intention.

Lougheed could have looked like the following instead, while still allowing for a three- or four-platform station. These are functional but not "fugly".

Yeah, the track layout is weird, but that's probably a consequence of the history and accommodating all train movements.
The original intent (in the LSRP) was for Coquitlam trains to run to Columbia or to VCC (a wye opening to the south, not the east).
That changed with the phasing of the line and the reorientation of the station (due to property and political issues).

People should just let go of the basketweave or the fact that SNC Lavalin bagged the contract instead of EL Partners. The examples shown here...

1) The one in New West was built out of necessity, not because of some grand design to make it pretty.

2) The Canada Line was built and designed in one go. There was no "phasing" or "extensions". The Evergreen Line is an extension. Had it been part of the original Millenium Line construction contract from the very beginning and built all in one go, perhaps the Lougheed guideways would have been prettier. But it is what it is, and just be thankful that its getting built.

After all, what is even uglier is the fact that you had that unfinished third platform all these years, with a hump to nowhere. The sole role of that unfinished abomination seems to generate a bajillion posts here in Skyscraperpage where forumers would speculate on how it will be built out in the future, for over a decade.

[Zassk]

My point was that the Lougheed structure looks like nothing else in the whole SkyTrain system. It's ugly not just because it was half-built, but also because it contrasts with what was built everywhere else on the M-line project. Why it was built in such a unique manner, I have no idea. I'm sure there's some history to that (or some engineer's pet project). Anyway, we are stuck with it now.

IIRC, the original steel truss/roof canopy design was to embody the trees around the area, and provide that architectural statement of being a regional centre/transit hub for the eventual evergreen line, with similar station treatment that was posted pages earlier. As gleaned from past open houses I've attended, there is a real desire to not have flyovers and superstructures for the stations, and having 3 distinct platforms also complicates things as well. Given all the possible track movements (and some missing, in my opinion) this had to be considered as well.

But to echo the current feeling, I'm just glad it's going ahead...I'll suffer with standard bus shelter glazing and wrong railing for a small section so I can get to Coquitlam on my one train ride from VCC-Clark

Not surprising, since it is one of the pillars built for the PoCo track stub, and was sitting unused for a decade since Lougheed was completed.

The mold, fungus and mildew (and other unidentifiable debris) on the unfinished trackbeds and the 3rd platform was disgusting, but since it didn't impact train service, nobody wanted to spend $$s to clean it up.

Pity whoever had to do the cleanup there at the beginning of this construction project.
