So power is off in Millwoods again this afternoon - Western Pacific trucks parked on both tracks at MWTC, one with a big spool of cable. Signal post across the from the firehall has a pile of wires hanging out the access hole at the base of the pole with another Western Pacific truck there. Why are we still pulling wires for the signaling system almost a month after the thing was supposed to be open?

What else isn't done that they are hiding behind the pier issue - seems to be a repeat of their constant blaming the concrete in the river for delays.

Maybe they can learn something from this 25+m pit they've excavated around existing Skytrain columns (and station in the background) in Burnaby.

Maybe the competent people were working on this instead of here - that would explain a lot.

I saw a bunch of work done on one of the piers east of 75 Street at the CN rail crossing. Also, the tarps and scaffolding are down north of Davies Station.

Closeup photos from tonight. These are the piers between the parking lot and 75 St, in that median between the SUP and road. Yes, those are box nails plugging the holes.

The piers on Wagner road just have more testing equipment on them. It looks pretty minimal, given how extensive the scaffolding etc was.

Or an epoxy injection point.
Lol i was just making an idle comment about the choice of materials. Given the effort put in to scaffolding and enclosing some piers, and the amount of patching and monitoring on this pier (this is the one that’s had the survey marker on it for the last few weeks), and the overall ‘scientific exploration’ happening, i just thought it was funny that these holes were plugged with nails from home depot. You can pull them out and put them back and they don’t seal. I’m sure it’s fine, I just thought it looked funny.
But yes, it’s likely they are for epoxy.

The material applied to the cracks is most likely Ultra High Toughness Cementitious Composite or UHTCC which, when properly bonded, will make the crack area stronger than the adjacent non-cracked area.
The hoarding and enclosure was simply meant to keep foreign particles from settling in the new composite.
