^Hard to believe I'm making excuses for ML - but - I'm not sure that skills trades shortage is the culprit here (although it may be a factor).
Playing amateur sidewalk superintendent here, it looks like a great deal of work has been accomplished (the trackbed now extends from the north end of the platform to the end of previously laid track on the eventual T1 at the West Toronto tunnel) (the bridge to the south is in the process of being shifted) (track bed is being readied to the south towards Parkdale).
The missing piece seems to be the formwork for the pedestrian tunnel(s). The excavation is complete, and has been shotcreted. It's not clear if some pause is needed to dewater. The presumed next step is for a foundation to be poured and formwork erected. The tunnel is then poured and then backfilled.
One theory is - we push the design of these projects too fast, and the contractor is not ready to proceed because drawings and paperwork aren't complete, or some other part of the procurement is not ready. If the case, that would definitely be on ML. (Wouldn't be the first time that someone has added a change request at the eleventh hour.....)(... or someone discovers a buried utility that wasn't on the drawings and needs to be moved....)
Another theory is - with the intense fishbowl around public projects, robust contingencies have been inserted in the plan, and we are seeing this as "delay" where it's actually just burning off the clock after the previously noted work was completed successfully on schedule. That's on ML but also on us as the public as observers - we get the amount of risk tolerance we ask for, and if we are obsessed with schedule adherence, the schedule will not take risks with timing. If we had demanded less float, maybe the contractor would have bid higher, but we won't pay for that.....
Theory three is - possibly the contractor is still busy with an earlier job and can't get to this one - it's on ML if the contract doesn't penalise the contractor for not showing on time, but even here - does ML fire the contractor and start procurement all over again? Certainly not. So the penalty can't be excessive and we swallow the delay.
All speculation, and in the end it doesn't matter - we want things moving faster, and clearly they aren't - but we better be sure we know the root cause before we try to solve this.
