I'm unironically curious about this though. All the preliminary roadwork and utility relocation seems to go by so slowly, as well as stuff like building bridges, but when they get to the tracklaying and all, it feels like these projects start to move way faster. Anyone in the construction industry have insight as to how the pace changes over the course of a project?

The first (and last) 10-20% typically goes much slower. Productivity and worker density is highest between 30-60% complete.

For very large projects 2-3 percent a month is high, but there's also a discipline based component; when we see large concrete pours we will probably see the number spike in civil, but electrical % per period may peak during the major cable pulls before terminations really get going.

As well underground work with existing utilities requires the right expertise and equipment. Hydro vac daylighting is costly, slow and disruptive; I'm guessing they don't do it 24/7.
 
There will be a lot of work on the stations during the winter. As well as all the Traction station (Power stations). But I agree this project seems to have a lot of lags. Stoney plain road looks like they just walked away a year ago. Those sections should have been done already.

I would point out that this only includes half of the major 2024 construction season. We won't know how successful construction was this summer until the Q3 report drops and it would not surprise me if there is a jump up into the 26-28% range. While there is only 2 weeks left in Q3 they are nearing completion (or have now completed) on a number of major elements such as elevated guide way installation, SPR bridge and AH bridge.

I'm also not feeling too pessimistic about this. The fact that the major pieces (bridges and guideways) are largely done and seem to have been built without any major deficiencies - at least that we know of so far - is a positive for me.

I wish the city still had the “baseline schedule”, like they did for the early days of the VLSE project reports. I think that gives a better idea of whether MIP is behind or not.

and that is precisely why we don't have one, can't let the public know what's going on...

Meh, I disagree. Both have their pros and cons. The independent certifier actually allows us to see how close we are to service commencement, but at such a distance to 2028, having it seems irrelevant.

Sad part when I think of it, is the area where west and south meet downtown has yet to be touched. I doubt that it's as simple as adding track.

I expect that entire section of road from 102 St -107 St will be closed during construction. Waiting until fall to close off the Avenue seems fine to me given the proximity to the Saturday Downtown Market.

yeah, we're too far out at this point...

If the public knows what's going on, the premier might decide to randomly cancel the project if there's any delay 🙄

It's not often I feel bad for Calgary, but the green line being cancelled is a tragedy

The only positive is that Edmonton is given a chance to catch up with the C-Train. Otherwise I feel bad that Calgary has received this major setback.
