Too bad they don't use "Roman concrete" (made from pozzolanic ash from near Mount Vesuvius. It reacted with lime and sea water to form a compound called calcium aluminate hydrate, contributing to the concrete's self-healing properties), but since Metrolinx is looking to save many, it would be too expensive to use. Metrolinx goes for the cheapest not the best.

I can't actually tell if this is a joke or not. Roman's didn't use concrete in the same way at all so every comparison is quite laughable.
 
No comment on the history lesson but concrete does need extended curing time for heavy loads. However, the rebar structure of the piers are relatively light weight so this work could move forward within a week if crews are ready.
 
One not so great news regarding Martin Grove station.

I had noticed that the tree clearing at Martin Grove station didn't include any mention of the western side of Martin Grove that was proposed for this station. I contacted the ECWE in the Metrolinx website and they stated that the decision has been made to have just one entrance at the northeast corner. Reasons listed were one entrance is sufficient for the demand, minimize impact to the community, avoid major construction in the roadway, and the need to relocate significant utilities. The final note in the email stated that this change keeps Martin Grove consistent with the other underground stations. Yes, consistently bad, that's for sure!

This means all underground stations only have entrances on one corner of the street. Folks de-boarding from buses on the other corners will have to made do with crossing 5-7 lanes (possibly twice) of high speed traffic before entering the station. Safety first mindset for the ECWE planners for sure!

As mentioned previously in this thread, pedestrian refugee islands (with beg button or motion detectors) are needed.

They should really build a bus loop to the north of the entrance building. This would help with riders getting to the entrance and allow route restructuring in the area.

The netherlands has by far the most impressive implementation of such a system where in many cases the motion detection will halt traffic only on the side of the road that has pedestrians walking, while allowing the opposit car traffic to continue flowing until the pedestrian reaches the island in the middle.
 
Construction pics posted today by the project's X account.

Let’s check in on the elevated guideway. Work has started on the piers, the reinforced concrete columns which will support the guideway.

Steel bars and spacers are added to the piers’ foundations – known as caissons – to make sure the concrete is evenly supported when poured.

Next, a steel reinforcement cage is built and a steel form, made of four large blue panels, is slid over the cage to shape the pier.

Concrete is then poured into the mold. It takes about four days to harden, at which point the mold is removed and the finished pier is revealed.The piers will vary in height, from 5 to 14 metres. In total, 54 piers will be built for the elevated guideway.

Now we wait till they contract out the systems/stations/rail contract and see how much this project balloons.

At least they only spent 1.6b for a completed tunnel and half way done with the second shorter tunnel.

wait a minute.... they dont have a contract on trackwork yet???!! what type of crack are they on to sit on their hands? now costs will be 2x higher vs a signed contract from last year.
 
This is how most of the recent Mx projects are phased. On ontario line the equivalent contract went out earlier as the MSF needed to be built. For Eglinton, a bunch of things this contract would do as advance works are already done by the main crosstown. Some of the work that would be done under this contract is also already being done by the existing contractors.

Its fine to phase the contract but to have such a wide gap in between is really risking cost escalation and further delays.
 
The work needs to happen when it's scheduled regardless of when you sign the contract, and the price would reflect that regardless of when it was signed (you plan for inflation to costs).
