Quite possibly the slickest construction site entry, or maybe testing a prototype for the TTC turnstiles?
Thereâs even a digital/video screen/card reader.

Not too much notable activity over the past week. On the north site, preparation work in advance of the start of the actual excavation activities is still under way. South site the major focus has been installation of the first level of the perimeter bracing - four more levels (for a total of five) to come.
The crane is still not in use - at the community conference call update on Thursday, October 3, the delay was attributed to a defective sensor, which is to be replaced. In the interim, mobile cranes are being brought in as required.
Sunday morning work underway at the north site at 8 AM. Still no excavation activity, site drainage work still to be completed, along with additional ground level concrete base for the supporting work area.
South side - Monday morning, October 7 - the tower crane is finally in regular operation.
Major milestone for the King Bathurst station this morning. Principal excavation has started on the north side of the station complex - excavator working, trucks arriving empty and leaving full. The north side excavation is to take place 24 hours a day, to excavate the access shaft and the station cavern itself. (The south side excavation is just for the passenger access portion of the station complex, will not be on a 24 hour basis.) the gantry crane on the north side is not yet operational - the gantry boom has not arrived, so mobile cranes are to be used in the interim.

North side excavation work moving quickly. Two excavators working, one well inside the hole, the joint of its boom is only partially visible when it is moving a load of earth over for the other excavator to remove.
Meanwhile on the south side, staging activities preparing for the next level of excavation.
October 15: In the absence of the gantry crane being ready for the north side (the cross-boom is still not here), up to the end of last week, digging was being done with a couple of excavators, the one that was lower in the hole piling up dirt at one end for the upper excavator to reach and load into the trucks. As of this morning, a temporary (hopefully) mobile crane is now on site to participate in the excavation process.
How it works - after the bin has been filled at the bottom of the shaft, the crane lifts it up and positions the bin beside the blue frame on the right. The blue frame has a flange on its side - the crane lowers the bin against the flange, and as it lowers down, the top of the flange puts upward pressure on the bin, allowing the bottom to open up and release the load. Once the bin is empty, the crane lifts up the bin, which causes the bottom to close back up, and lowers the bin back into the shaft. One bin load per truck. The filled truck pulls out and the next empty truck pulls into position while the bin completes its fill cycle in the shaft.
October 23 - Next stage of excavation for the south side has started. Along with a site worker putting on a show for the picture.
North side - trim being installed along the corner - suspect that it is more to stop the wind catching the canopy covering than for its esthetic effect.
Flange device used to open the bins of excavated earth. This one is from the south side of King Street, not in use yet as the excavators can still load directly into the trucks, but is the same as the one in the north side being used in the post above.
